Zinc Oxide Lightning Arrester
Zinc Oxide Lightning Arrester is a new type of lightning arrester with good protection performance, it mainly has zinc oxide varistor composition. The zinc oxide surge arrester of ZMS adopts a high-quality composite insulation jacket, which has the advantages of miniaturization, safety, and maintenance-free products. Compared with traditional inorganic materials such as ceramics and glass, polymer conforming materials have the characteristics of small size, lightweight, high dirt resistance, explosion-proof, and shockproof.
Main Types: HY5WS, HY5WZ, HY5WR, HY5WT, HY5WD, HY10WZ, HY5WX
Zinc Oxide Arrester for Overhead Line Transmission
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.
Zinc Oxide Lightning Arrester Has Seven Main Characteristics
Through-Current Capability
Mainly reflected in the arrester has the ability to absorb a variety of lightning overvoltage, frequency transient overvoltage, operating overvoltage.
Protection Performance
Zinc oxide lightning arrester has good protection performance. It can protect various electrical appliances in the power system from voltage damage.
Sealing Performance
Arrester components using aging performance, good gas tightness of high quality in line with the outer sheath. Ensure that it is sealed reliably, so that the performance of the arrester is stable.
Mechanical Performance
Lightning arrester has excellent ability to withstand earthquake force. Has excellent ability to prevent high wind pressure. The top of the arrester bears the maximum allowable pressure of the overhead conductor.
Anti-Fouling Performance
Gapless zinc oxide arrester has high fouling resistance.
Work Frequency Withstanding Ability
Due to the power system, such as single-phase grounding, long line capacitance effect and dumping load and other reasons, will cause the rise of the industrial frequency voltage or generate a high amplitude transient overvoltage. Lightning arrester has the ability to withstand certain frequency voltage rise in a certain period of time.
Long-Term Operational Reliability
ZMS manufacturing companies zinc oxide arrester has high product quality and reasonable product selection. ZMS strictly requires itself to ensure the following three aspects of quality assurance: the rationality of the arrester finishing structure, the voltammetric characteristics of the zinc oxide valve piece and aging resistance characteristics; the sealing performance of the arrester. to achieve long-term effective operation of the product.
