The 3 Best Composite Insulator Types of 2024

Composite insulators have become increasingly popular in electrical applications due to their lightweight design and superior performance. Here, we highlight the three best composite insulator types of 2024, explaining their components and advantages. A typical composite insulator consists of a core made of fiberglass or plastic, covered with a weather-resistant outer layer, often made from silicone or rubber. Key parts include:

 

  1. Core: Provides mechanical strength.
  2. Housing: Protects against environmental factors.
  3. End Fittings: Connects the insulator to electrical equipment.

Composite Insulator Parts

Composite insulators, also known as organic composite insulators, rubber insulators, or non ceramic insulators, are composite structural insulators made of organic composite materials, mainly composed of core rods, hardware, umbrella skirt sheaths, and adhesive layers.
 "Hardware is a transmission component of the mechanical load of a composite insulator, which is assembled with a core rod to form a connecting piece of the composite insulator.". The quality of the structure affects the strength of the core rod and the mechanical properties of the insulator.

 The umbrella skirt sheath is the external insulation part of the composite insulator , which is used to ensure that the composite insulator has sufficiently high external insulation performance against moisture and pollution flashover, and to protect the core rod from atmospheric erosion.

 The core rod is the load-bearing component of the mechanical load of the composite insulator, and is also the main component of the internal insulation.

 A part of the adhesive layer is used to complete the connection between the sheath and the core rod with adhesive; The other part is to use potting glue to complete the connection between the umbrella skirts. The quality of bonding is directly related to the level of internal insulation.

Why Use Composite Insulator？

High strength, light weight.

The strength of the composite insulator weight ratio is very high, the specific strength is very high. Its high mechanical strength comes from glass steel reinforced bar excellent mechanical properties, the glass fiber reinforced plastic in use by a large number of led the tensile strength of the pull rod can reach more than 1000 mpa and the mandrel is only about 2 g/cm3 density, so its strength is very high, which is about 5 ~ 10 times of quality carbon steel. Under the same voltage grade, the weight of the composite insulator only 1/7 ~ 1/10 for porcelain insulator

The wet flashing lightning pressure is high.

Low energy on the surface of hydrophobic organic composite material is the main reason for the composite insulator is excellent wet dirt resistance.

Haivo Advantage---Composite Insulator

The advantages of composite jacket insulators are good hydrophobicity, light weight, but poor UV resistance, easy aging and cracking, and short service life; Porcelain or glass insulators are heavy, adding to the burden on poles and towers, resulting in high cost.However, our company's composite outer insulator front extrusion and umbrella wearing process replaces the composite umbrella skirt with a large disc diameter and thin porcelain umbrella skirt, and sets porcelain tubes between the umbrella skirts.

Advantage

1. Porcelain umbrella skirt and porcelain sleeve are made of inorganic materials, which have strong ultraviolet resistance, are not prone to aging and cracking, and have an exceptionally long service life;

2. The disc diameter, umbrella spacing, and creepage distance of the porcelain umbrella skirt can be adjusted at will. The large inclination angle of the umbrella increases the "protective creepage distance" of the insulator. Even if the upper half of the umbrella skirt is seriously misunderstood, due to the large protective creepage distance, it is safer to operate in rainy and foggy days.

3. The manufacturer of "Long Rod Extruded Porcelain Umbrella Skirt Insulator" only needs production equipment and testing equipment for extrusion, umbrella wearing, and seizure (outsourcing of porcelain umbrella skirt and porcelain sleeve), saving a large amount of equipment and mold investment required for the production of composite and glass insulators, and reducing production costs.
