The company is a formal high-tech enterprise, certified by the ISO9001 quality management system. All high-voltage products have passed national authoritative testing and type testing. We possess legal qualifications for production, sales, bidding, and supply, and can provide a complete set of qualification documents, test reports, and certificates of conformity.

Yes. Customized production is available based on project conditions, drawing parameters, and power grid standards. We support engineering support, OEM manufacturing, and bulk supply, meeting the needs of various projects, including State Grid, rural power grids, industrial enterprises, and photovoltaic/wind power.

Indoor circuit breakers (VS1/VD4 series) use epoxy resin insulation and steel plate cabinets, featuring a compact structure suitable for indoor switchgear use and offering high cost-effectiveness. Outdoor circuit breakers (ZW series) use silicone rubber composite insulation and stainless steel enclosures, providing waterproof, sunproof, anti-flashover, and salt spray resistance, allowing for all-weather use on outdoor poles.

Conventional vacuum circuit breakers have a mechanical life of over 10,000 cycles. The arc-extinguishing chamber maintains a stable vacuum, enabling long-term maintenance-free operation under normal conditions. Only annual routine inspections, bolt tightening, and insulation cleaning are required.
