Zinc Oxide Lightning Arrester
Zinc oxide lightning arrester is an essential overvoltage protection device widely used in power transmission and distribution systems. It adopts high-performance zinc oxide resistor discs with excellent non-linear voltage-current characteristics, no series gap, fast response and large discharge current capability.
ZMS lightning arresters are made of high-quality silicone rubber composite housing, featuring good waterproof, dustproof, anti-pollution and explosion-proof performance. With a small volume, lightweight, maintenance-free design, it is the ideal choice for power system lightning protection.
It is mainly suitable for 10kV, 35kV, 110kV and other voltage levels, widely used in substations, distribution cabinets, overhead lines, cable terminals and box transformers.

10kv Zinc Oxide Lightning Arrester
The product is made of zinc oxide based multi-metal oxide powder firing. It has intentional nonlinear volt-ampere characteristics, fast steep-slope response, large through-current capacity, etc. Gapped products use self-blowing gaps with equal pressure irradiation structure, which reduces the dispersion of discharge and has a small impact factor.
Zinc Oxide Arrester Features
- Small volume, light weight, collision resistance, transportation without touching loss, flexible installation, especially suitable for use in the switchgear.
- Special structure, overall molding, no air gap, good sealing performance, moisture-proof and explosion-proof.
- Large creepage distance, good water enhancement, strong dirt resistance, stable performance, reduce operation and maintenance.
- Unique formula of zinc oxide resistor sheet, high capacity, low leakage.
35kv Zinc Oxide Lightning Arrester
The core working element of this product is made of zinc oxide based multi-metal oxide powder firing. It has excellent nonlinear volt-ampere characteristics, fast steep-slope response and large through-current capacity. The use of polymer organic composite insulation outer sheath ensures the product’s smaller size, lighter weight, fouling resistance and excellent anti-explosion and anti-vibration characteristics. The product is commonly used in AC 220kV and below power generation, transmission, substation and distribution systems.

Detachable Zinc Oxide Arresters
Detachable lightning arrester can also be called drop type zinc oxide lightning arrester. The drop arrester is a distribution type zinc oxide arrester modified and cleverly installed on the drop mechanism of the drop fuse. Reach can be easily detected, repaired and replaced with the lightning arrester with the help of insulated pull lever, in the case of non-stop power.
Zinc Oxide Arrester Features
- Arrester unit can be loaded and unloaded at any time with electricity. Especially suitable for places where power failure is not appropriate.
- With disconnector, the arrester unit failure can automatically turn down and exit operation, the fault line normal operation.
- Due to the failure of the unit turned down to form a clear sign, easy to find, timely maintenance and replacement.
- Lightning arrester using composite jacket, falling mechanism using composite pillar, good water repellent, strong dirt resistance.
Lightning Arrester With Hot Fusion Type & Hot Explosion Type Disconnector
Lightning arrester disconnector is an accessory of lightning arrester, and lightning arrester used in series. Its purpose is when the arrester has an abnormal fault, the use of the arrester flowing through the frequency short-circuit current so that the disconnector action. So that the grounding end of the disconnector automatically disconnected, the arrester out of the system operation, to prevent further expansion of the accident.
Zinc Oxide Arrester Features
- Adapt to a wide range of action current: the product can be disconnected under a large frequency fault current (> 50A), but also under a small frequency fault current (50mA).
- Fast disengagement speed: it can be matched with the reclosing function of circuit breaker, which is not only applicable to various voltage levels and various types of lightning arresters, but also different grounding systems.
- High mechanical strength and good sealing performance: disconnector has high mechanical strength and good sealing performance before the action burst off.
- Easy to install and replace: disconnector using threaded external interface, and lightning arrester series connection is extremely convenient and reliable. Disconnector once the action is very convenient to replace, save time and effort.
