Description

Technical Parameters

Gaodian Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of substation surge arrester in China. With abundant experience, we warmly welcome you to buy advanced substation surge arrester made in China here from our factory. We also accept customized orders.

This Polymer Surge Arrester is primarily installed in the power distribution rooms of substations or large industrial and mining enterprises:

Preventing overvoltages caused by lightning surges or internal system operations (such as large switchgear switching) from damaging the insulation of expensive equipment such as transformers, transformers, and circuit breakers.

Limiting overvoltage amplitude: Limiting instantaneous high voltage on the line to within the range that equipment can withstand.

Improving power supply reliability: Reducing power outage by maintaining low leakage current and stable insulation to prevent equipment from being damaged by overvoltage.

Key Advantages

advantages of substation surge arrester

Ultra-Fast Response

Zinc oxide surge arresters remove the conventional series discharge gap structure, achieving an ultra-quick response speed at the nanosecond level.

Strong Pollution Withstand Capability

Adopting silicone rubber composite housing, the material features outstanding hydrophobicity. It can effectively restrain surface creepage discharge even under heavy pollution, salt fog and high humidity environments.

High Safety & Anti-Explosion Performance

It will not burst or produce flying debris when electrical faults occur, greatly enhancing operational safety.

Low Maintenance Requirement

Superior sealing performance keeps internal ZnO resistor elements permanently dry, making the product maintenance-friendly and hassle-free.
