Haivo's load break switch is light and easy to handle. You can check each part without trouble. Regular checks help you find problems early and keep your system safe.
It is important to keep contacts clean. Clean contacts help the load break switch work well. Dirt or dust can make connections bad. Oxidation can also cause overheating. There are two main cleaners you can use. Solvent-based cleaners are good for tough dirt. Water-based cleaners are safer for people and nature. Most jobs need a special contact cleaner. This cleaner removes dirt fast and well.
Here is an easy way to clean contacts:
Pick a contact cleaner that fits your contact type.
Put the cleaner on with a cotton swab or soft brush.
Clean the surface gently. Do not push too hard.
Wipe off extra cleaner and dirt.
Tip: Let the cleaner dry all the way before turning the switch on.
Cleaning Method | Description |
|---|---|
Specialized Contact Cleaners | Solvent cleaners remove dirt from contacts quickly. |
Mechanical Cleaning Methods | Brushes or swabs take dirt off contact surfaces. |
Insulators stop electricity from leaking out. Always clean insulators before using the switch for the first time. This is very important for SF6 load break switches. Dust or dirt on insulators can cause problems. When cleaning, look for cracks or damage. Broken insulators can be dangerous. Use a dry cloth or soft brush to clean off dust. If you see cracks, change the insulator right away.
The enclosure keeps inside parts safe from water, dust, and chemicals. When you clean the load break switch, clean the enclosure too. Use a damp cloth to wipe off dirt. Make sure gaskets seal tight to keep out water. Check that latches close all the way. If there are vents, make sure they keep water out to stop moisture from building up.
Note: Keeping the enclosure clean helps stop contamination and keeps the switch safe.
It is important to keep moving parts working well. These parts are linkages, handles, and the opening mechanism. If these parts get dry or sticky, the switch may not work. You might notice slow movement or hear grinding sounds. Good lubrication stops these problems and keeps your system safe. Always look for old grease or signs of wear before adding new lubricant.
Tip: Clean off old grease and dirt first. This helps new grease work better and last longer.
Picking the right lubricant is important for switches. You need a product that stops rust and helps parts move easily. Manufacturers suggest different lubricants for load break switch moving parts. Here is a table to help you choose:
Lubricant Type | Description |
|---|---|
Mineral oil-based greases | Good for normal temperatures and loads. Easy to find and cheap. |
Synthetic greases | Work in very hot or cold places. Handle heavy loads. Cost more but last longer. |
Solid lubricants | Best for dry or tough places. Protect for a long time with less maintenance. |
Do not use graphite, molybdenum disulfide, or PTFE lubricants on electrical contacts. These can make resistance go up and cause trouble. Do not use metal-filled lubricants unless you know they are safe. Some materials can cause rust or let electricity go where it should not.
Lubrication is an important part of regular maintenance. You should check and add lubricant during every inspection. If you do this, your load break switch will last longer. Skipping lubrication can make switches fail early. Replace worn parts when you see them. Good lubrication keeps switches working and your network safe.

Replacing worn parts makes switches last longer.
Routine maintenance stops breakdowns and keeps things safe.
Always follow your manufacturer's schedule for the best results.
You should check insulation resistance often. This helps you find problems early. Use a megohmmeter to see if insulators stop electricity from leaking. High insulation resistance means your load break switch is safe. Low resistance can mean there is moisture or dirt. Clean the insulators and test again. Write down your results so you can see changes later.
Tip: Test insulation resistance after cleaning and before using the switch again.
Contact resistance testing is needed for every distribution network. Use a low-resistance ohmmeter to check how well contacts carry current. Try to get values less than 1 ohm. Low contact resistance keeps switches working well and stops overheating. If resistance is high, clean the contacts and tighten connections. Change any worn parts if resistance stays high.
Here is a simple table to help you understand contact resistance testing:
Test Tool | Target Value | What It Means |
|---|---|---|
Low-resistance Ohmmeter | < 1 ohm | Good contact, safe operation |
Low-resistance Ohmmeter | > 1 ohm | Possible problem, check contacts |
Functional checks make sure your load break switch works right. Follow these steps when you test:
Make sure the switch moves smoothly and parts are strong.
Measure contact resistance to stop overheating.
Do a dielectric test to check if insulation is strong.
Test the switch under load to see if it opens and closes safely.
Interrupt current flow to see if the switch can handle faults.
Do these tests every time you finish maintenance. This keeps your system safe and working well. Regular testing helps you find problems early and avoid downtime in your distribution network.
Always follow safety rules when you do electrical testing.
Check your load break switch for parts that wear out. Some parts work hard every day and get weak. When you look at switches, watch for these common worn parts:
Contacts: These touch when the switch opens or closes. Arcing can wear them down and make them work less well.
Springs: Springs help the switch move fast. If they get loose, the switch may not work right.
Linkages: Linkages connect moving parts. Wear can make them stiff or loose.
Insulation materials: Insulators keep electricity in the right place. Dirt or cracks can make them weak.
If you find any worn parts, replace them. This keeps your switch safe and working well. You can use a table to track which parts need fixing:
Component | Signs of Wear | Action Needed |
|---|---|---|
Contacts | Pitting, erosion | Replace |
Springs | Loss of tension | Replace |
Linkages | Stiffness, looseness | Repair/Replace |
Insulation material | Cracks, dirt | Clean/Replace |
Tip: Always use the manufacturer's guide when you change parts. This helps you avoid mistakes and keeps your system safe.
Look for damaged parts every time you check the switch. Damage can happen from heat, water, or stress. If you see broken porcelain, bent handles, or cracked enclosures, fix them fast. Damaged parts can cause problems or be unsafe.
Fix broken pieces right away and check for other issues. Sometimes, tightening connections can fix loose parts. If you ignore damage, your load break switch may stop working or be unsafe.
Keep a record of repairs you do. This helps you see patterns and plan future checks. Regular checks and quick fixes keep your switches working well and help them last longer.
You must follow lockout/tagout steps before working. These steps keep you and your team safe from electrical danger. If you skip them, you could get hurt or break equipment. Use this table to help you do each step:
Step | Description |
|---|---|
1 | Tell everyone about the lockout/tagout and why you are doing it. |
2 | Turn off equipment slowly to stop hazards. |
3 | Find and use devices to cut off all energy. |
4 | Put locks and tags on devices to keep them safe. |
5 | Get rid of leftover energy by disconnecting and holding it back. |
6 | Make sure everyone is safe and pick the right safety gear. |
Always check every step twice. Missing a step can break equipment or hurt you.
You need the right safety gear for every job. The kind of PPE depends on the switch and how much energy there is. Always check how much energy could be there before you start. Use tests or tables to pick the best protection. This keeps you safe from arc flash and lowers the chance of getting hurt or breaking equipment. Wear gloves that insulate, safety glasses, and clothes that resist flames.
Always use safe habits when you work on a load break switch. Follow all safety rules and do not hurry. Keep your work area neat and dry. Use tools that insulate and stand on a rubber mat. Never touch parts that have power. If you see sparks or hear odd sounds, stop and tell someone. Good safety habits stop accidents and help your equipment work well.
Remember: Safety is most important. Careful work and good habits keep you and your team safe from harm.
You should check your switches often. Regular checks help you spot problems early. This keeps your system safe. Experts say to follow rules like NEMA Standards Publication KS 3. These rules tell you how to inspect and take care of switches. They work for places like factories and big buildings. Look at your load break switch at least every six months. If your switches are used a lot or in tough places, check them more often.
Check switches every six months.
Check more often in dusty or wet places.
Write down each check in a logbook.
Regular checks help you find wear or rust before it gets bad.
Cleaning is important for scheduled maintenance. Clean contacts, insulators, and enclosures every time you check the switch. Dust and dirt can pile up quickly, especially outside or in busy places. Clean your load break switch before you use it for the first time. After that, clean it at least two times each year. If you see dirt or water, clean the switch right away.
Part to Clean | How Often |
|---|---|
Contacts | Every 6 months |
Insulators | Every 6 months |
Enclosure | Every 6 months |
Tip: Clean more often if there is lots of dust or water.
Lubrication helps moving parts work well. Add lubricant every time you do scheduled maintenance. Always wipe off old grease before you put on new grease. Most makers say to lubricate linkages, handles, and opening parts every six months. If you see slow movement or hear noise, add lubricant right away.
Lubricate moving parts every six months.
Use the right lubricant for your switch.
Change worn parts when you check the switch.
Haivo Electrical makes switches that last a long time. You do not need to do much maintenance. The switches work well for many years.
Contacts inside load break switches can get corroded as time passes. This happens when you use the switch and electric arcs appear. High current and arcs make oxidation and corrosion worse.
When you open or close an electromechanical switch, contacts wear down a little. High current and electric arcs can cause oxidation and corrosion.
Here are some problems you should watch for:
Moisture can cause oxidation or corrosion. This makes an oxide layer and raises resistance.
Different metals can react in wet places. This makes compounds that stop electricity.
Using the switch a lot can bend contacts. Bent contacts can corrode more.
You can stop contact corrosion by keeping switches dry and clean. Check switches often to find corrosion early. Replace bad contacts before they hurt your network.
Environmental contamination can make load break switches have problems.
Metal parts can rust when moisture is around.
Humidity can hurt insulation and cause short circuits.
Humidity can raise contact resistance. This can waste power and make things hot.
Humidity can lower thermal performance and damage the switch.
Keep switches safe from dust, water, and chemicals. Clean enclosures and check seals often to stop these problems.
Mechanical wear hurts moving parts in load break switches.
Look for broken pieces and rust.
Check for bad wires and grounding issues.
Make sure there are no wiring mistakes or loose wires.
Clean the outside of the breaker to stop overheating.
Lubricate moving parts as the maker says.
You can lower mechanical wear by doing regular maintenance. Change worn parts fast to keep switches working well.
Insulation aging happens a lot in load break switches.
High temperatures make insulation break down faster, especially in factories.
Bad sealing lets moisture in. This weakens insulation and raises the chance of faults.
Insulation gets weaker with age from moisture, heat, and chemicals.
Mechanical wear can also make insulation fail, especially in hot places.
Insulating materials get worse over time, especially with heat and moisture.
Check insulation often and change it if you see aging. Good insulation keeps your network safe and working well.
You might ask how load break switches are different from vacuum circuit breakers. Both help control electrical circuits, but they do not work the same way. Load break switches open or close a circuit when things are normal. Vacuum circuit breakers can stop much bigger currents, especially if there is a fault.
Here is a table that shows how they are not the same:
Feature | Load Break Switch | Circuit Breaker |
|---|---|---|
Primary Function | Open/close circuit under normal load current | Automatically interrupt fault currents; manual control |
Protection Capability | No inherent fault protection | Provides fault protection (overload, short-circuit) |
Interrupting Capacity | Limited to normal load currents | High interrupting capacity for fault currents |
Operating Mechanism | Manual or motor-operated, slower | Automatic trip mechanism, rapid operation |
Typical Application | Isolation, sectionalizing, switching normal loads | Overcurrent, short-circuit, motor protection |
Trip Characteristics | None (does not trip automatically) | Defined trip curves (instantaneous, long-time, etc.) |
Vacuum circuit breakers do not need much maintenance. You only need to check them about once a year. They last a long time and do not break often. This makes them good for places where you want less work and high dependability.
Tip: Pick vacuum circuit breakers if you need strong fault protection and want to spend less time on maintenance.
Gas-insulated switchgear uses special gas, like SF6, to keep electrical parts safe. You see GIS in places where there is not much room or where you need extra safety from the weather. GIS keeps out dust, water, and chemicals.
You must check the gas pressure and look for leaks when you do maintenance. Gas leaks can hurt the environment, so you should fix them quickly. GIS lasts a long time, but you need to follow the maintenance plan to keep it working well.
Note: Use GIS if you need small equipment and strong protection from bad weather or pollution.
You need to check your load break switch often. This helps you find problems early. Make a list for each inspection. Write down what you see every time. Fix any problems as soon as you find them. Doing regular maintenance stops sudden failures. It also helps your electrical system last longer.
Tip: Set reminders so you remember to check your switch. This way, you will not forget any inspections.
Pick switches made from strong materials. Good materials do not rust or wear out fast. Using high-quality parts makes your system safer. You will not have to fix things as much. Haivo Electrical uses advanced materials in their switches. This gives you better performance and longer use.
Here is a table that shows the benefits:
