Import 11kv Metal Oxide Lightning Arrester — Buy in wholesale FOB from Supplier in China

Zhejiang Langao Power Technology Co., Ltd, located in Yueqing City, Zhejiang Province, manufactures 11kV metal oxide lightning arresters for overvoltage protection in medium-voltage power distribution systems. These arresters use zinc oxide (ZnO) based varistor blocks as their core active components, which provide non-linear voltage-current characteristics to clamp transient overvoltages while maintaining high impedance under normal operating voltage. The supplier states the product uses integral injection molding and a two-sealing technology for enhanced environmental protection.

Metal oxide arresters (MOAs) are the standard technology for surge protection in modern electrical networks, having largely replaced older silicon carbide designs. The ZnO varistor formulation determines the arrester's protective level and energy absorption capability. Typical 11kV arresters are designed to protect distribution transformers, cable terminations, switchgear, and other connected equipment from lightning-induced and switching-induced voltage surges. The supplier notes features including electrical erosion resistance, aging resistance, and a compact, lightweight design for easier installation.

These arresters are purchased by power utilities, transformer manufacturers, and electrical infrastructure contractors for both new installations and replacement in existing networks. The listing indicates the product is intended for distribution system protection. Buyers should request specific technical data sheets from Zhejiang Langao Power Technology, including rated voltage, continuous operating voltage, nominal discharge current, and pressure relief class, as these critical parameters are not detailed in the current listing.

Zhejiang Langao Power Technology Co., Ltd is based in Wengyang Industrial Zone, Wengyang Street, Yueqing City, Zhejiang Province, China. Yueqing is a well-known hub for electrical equipment manufacturing in China. The supplier holds a 'harbor' trust tier on the platform, with a response rate of 0.00 and no average response hours recorded, which may indicate a recently added or not yet fully engaged profile.

The company's listing focuses on 11kV metal oxide lightning arresters, describing them as advanced overvoltage protectors for distribution transformers and electrical equipment. The product description highlights ZnO varistor technology, integral injection molding construction, and dual-sealing for environmental resistance. No information is provided regarding the company's founding year, number of employees, production capacity, export markets, or quality management certifications in the available data.
