FAQ

Get answers to common questions about surge arresters.

What is a surge arrester?

A surge arrester is core overvoltage protection equipment for power grids. It relies on zinc oxide varistors with excellent nonlinear characteristics to rapidly discharge lightning surges and transient overvoltage to ground, limiting system voltage within safe ranges and protecting transformers, circuit breakers and other power equipment from insulation breakdown damage.

How do I install a surge arrester?

Installation methods vary by product type. Station arresters are fixed on support frames, line arresters are mounted on tower crossarms, and neutral-point arresters are connected to transformer neutral terminals. We provide complete step-by-step installation manuals, standard installation accessories, and professional remote video guidance; for large projects, on-site engineer support is available upon request.

Which power system scenarios use surge arresters?

Our arresters cover all mainstream power scenarios: high/medium/low voltage substations, overhead transmission lines, distribution transformers, transformer neutral points, wind farms, photovoltaic power stations, industrial power distribution rooms and cabinet power systems.

Are surge arresters safe for grid operation?

Yes. All our arresters pass strict IEC standard testing, equipped with anti-explosion, pollution-resistant and thermal runaway prevention structures. Composite housing products feature flame-retardant insulation materials to avoid fire risks during failure, ensuring long-term stable and safe grid operation

Can surge arresters be used in outdoor harsh environments?

Absolutely. Composite silicone rubber housings have strong resistance to UV radiation, acid rain, salt fog and extreme temperature fluctuations (-40℃ ~ +60℃). Porcelain housing types are suitable for heavily polluted industrial and coastal areas; we also offer customized anti-fouling coating solutions for ultra-severe environments.

How to select the correct surge arrester model for my project?

You only need to provide your system rated voltage, installation scenario (substation/line/neutral point), nominal discharge current requirement and local environmental pollution level. Our electrical engineers will match the corresponding model, rated voltage and residual pressure parameters for free, and provide targeted protection schemes.

Do you supply surge arresters with different housing materials?

Yes. We have two mainstream housing options: lightweight composite silicone rubber housing and high-insulation porcelain housing. Composite types are widely used for lines and mobile stations; porcelain types are preferred for heavy-pollution outdoor substations. Custom color and surface coating are also available.

What is the price range of your surge arresters?

Prices depend on voltage grade, housing material, technical parameters and order quantity. Small distribution network arresters have competitive unit prices, while high-voltage station arresters with customized structures have separate quotations. We offer volume-based wholesale discounts and stable factory direct supply without middlemen markup.

What is the service life of surge arresters?

Under normal operating and environmental conditions, our zinc oxide arrester products guarantee a service life of more than 20 years. We adopt high-purity zinc oxide resistor sheets and anti-ageing insulating housing, greatly reducing performance attenuation during long-term operation. Regular routine inspection can further extend service cycle.

Where can I purchase your surge arresters?

We are a direct manufacturer supporting global wholesale and project orders. You can send RFQ via email or online inquiry form, our sales team will reply within 24 hours. We support flexible FOB/CIF/DDP trade terms, arrange global logistics and provide full set of certification documents for customs clearance.
