XASR is committed to R&D and manufacturing of high-strength and high conductivity copper alloy materials, medium and high voltage electrical contact materials, copper chromium vacuum contact materials and CuCr contact materials.
Copper tungsten series contact materials and composite contact materials, high conductivity and high strength chromium zirconium copper series alloy materials, copper iron series alloy materials, and other special copper alloy materials…
Medium and high voltage electrical contact materials and products are mainly used in medium and high voltage switchgear, responsible for connecting and disconnecting circuits and load currents.
Normally,the application range of copper chromium contact products is 12KV-126KV, and the application range of copper tungsten contact products is above 126KV.
At present, XASR has made significant breakthroughs in the field of high voltage, high current, and large specification contact products, and has comprehensively developed copper chromium contacts for 126kV and 252kV high voltage level vacuum switches.
At the same time, the company participated in the national key research and development plan (key technology for 252 kV high-capacity vacuum breaking fully enclosed combination electrical appliances), which aims to eliminate the contradiction between vacuum breaking, insulation, and current flow at the 252 kV voltage level.
