Its product range covers power fittings, clamps, cable accessories, insulators, switches, breakers, fuses, arresters, and related products. Evidence supports ISO 9001 and ISO 14001 certification, dedicated research and testing facilities, production licensing, and product testing by several Chinese power-industry institutions. The supplied information does not sufficiently establish after-sales execution, financial credibility, customization capability, or identifiable customer cases. Some company-scale data is inconsistent across records, including employee count, establishment history, and facility size, so those details should be verified.

Supplier typeThe supplier is identified as a combined, limited company headquartered in Zhejiang, China, engaged in electrical and electronics and offering a broad portfolio of power fittings, cable accessories, switching equipment, and protection products. It also reports export activity and accepts FOB, CIF, and CFR quotation terms, indicating capability to engage in international trade.

These records provide explicit evidence of quality and environmental management certifications and product compliance-related credentials.

R&D capabilityThe supplier reports a dedicated technical research and development center recognized as a provincial township business technical service center and enterprise technical center, together with machinery, physics, chemistry, pressure, partial-discharge, and heat-cycle testing facilities. This directly supports established R&D and technical testing capability.

Production capacityEvidence includes a stated 35,000 m² manufacturing plant, production licenses, advanced laboratory equipment, a broad product portfolio, and testing of electric anchor clamps and related products by multiple power-industry institutions. The records support meaningful manufacturing capability, although company-scale figures differ across slices and should be verified.

Product Q&A

Q:How does the arrester disconnect during a fault?

When the arrester ages or fails, a power frequency short-circuit current flows, activating the disconnector (hot-melt or thermal-explosion type) to automatically drop and disconnect the element from the line.

Q:Can the arrester be replaced without shutting down the power?

Yes, it is designed for easy operation with an insulating hook stick under live-line conditions, allowing installation and replacement without de-energizing the line.

Q:What voltage levels does this arrester support?

It is designed for overvoltage and lightning protection in 10-35kV distribution networks, suitable for poles, towers, and distribution transformers.

Q:What materials are used for the insulator support?

The arrester consists of a silicone rubber or porcelain insulator support post, offering flexibility for different environmental requirements.

Q:Is the manufacturer capable of custom orders?

Yes, the company provides both OEM and ODM services and has 50 R&D engineers to support product development.
