Description

Haivo's 15kV Polymer Metal Oxide Lightning Surge Arrester is an advanced overvoltage protection device engineered exclusively for 15kV power transmission and distribution systems. As a leading manufacturer of electrical protection equipment, we design our gapless zinc oxide (ZnO) arresters to deliver superior performance against lightning strikes and switching surges, safeguarding critical infrastructure from costly damage and unplanned downtime. Our product line includes both silicone polymer and porcelain housing options to meet diverse environmental and operational requirements.

How Does a Gapless Metal Oxide Surge Arrester Work?

Unlike traditional spark-gap arresters, our gapless design leverages the exceptional non-linear volt-ampere characteristics of zinc oxide. At normal operating voltage, the arrester exhibits extremely high electrical resistance, allowing only microampere-level leakage current to flow. When an overvoltage event occurs, the resistance drops instantaneously, safely discharging surge energy to ground. Once the overvoltage subsides, the arrester automatically returns to its high-resistance state, ensuring continuous protection without the need for resetting.

Key Features & Benefits

Silicone polymer housing: Delivers excellent pollution resistance, UV stability and hydrophobic properties, ensuring reliable operation in harsh outdoor environments and extending service life to 20+ years.

Gapless construction: Eliminates discharge delay, providing faster response time and higher reliability compared to gapped designs.

Superior sealing capability: Prevents moisture ingress and internal contamination, maintaining stable performance throughout the product lifespan.

Easy installation and maintenance: Lightweight design reduces installation time and labor costs, while minimal maintenance requirements lower total ownership cost.

Wide operating temperature range: Functions reliably between -40℃ and +40℃, suitable for deployment in extreme climate conditions worldwide.

FAQ

What is the difference between polymer and porcelain housing surge arresters?

Polymer housing arresters are lighter, more impact-resistant and offer better pollution resistance compared to porcelain housing models. They are ideal for coastal areas, industrial zones and regions with high pollution levels. Porcelain housing arresters are more economical and suitable for general-purpose applications in clean environments.

What nominal discharge current ratings are available for 15kV surge arresters?

We offer 5kA, 10kA and 20kA nominal discharge current ratings for 15kV systems. The 5kA series is suitable for standard distribution applications, while the 10kA and 20kA series are recommended for high lightning activity areas and critical infrastructure.

Can your surge arresters operate at altitudes above 2000m?

For installations above 2000m, we can provide specially designed surge arresters with enhanced insulation performance to compensate for reduced air density at high altitudes.

Do you offer custom-made surge arresters?

Yes, we provide customized solutions including special voltage ratings, creepage distances and mounting configurations to meet specific project requirements.

What is the warranty period for your products?

All Haivo surge arresters come with a 2-year comprehensive warranty against defects in materials and workmanship. Extended warranty options are available upon request.
