MV Switchgear Parts & Epoxy Insulation Components
XBRELE manufactures precision-engineered Switchgear Parts for 12kV-40.5kV power systems. We supply the critical insulation backbone for KYN28, XGN, and GIS panels, ensuring seamless integration and IEC compliance.
Featuring advanced APG Technology and strict X-Ray Flaw Detection, our components deliver superior dielectric strength and zero partial discharge reliability.
Engineered for KYN28 & GIS Panel Reliability
XBRELE supplies the critical “passive ecosystem” for Medium Voltage power distribution. From the insulation backbone to the conductive core, our components are precision-molded to withstand the rigors of 12kV–40.5kV networks.
Quality starts with material science. We utilize international advanced APG (Automatic Pressure Gelation) technology for all Epoxy Contact Boxes and bushings, ensuring bubble-free insulation with superior dielectric strength. Every batch undergoes rigorous X-Ray flaw detection and Partial Discharge (PD) testing to guarantee zero internal defects.
Our mechanical portfolio is equally robust. Designed to integrate seamlessly with Vacuum Circuit Breakers, our high-purity T2 Copper Contacts feature thick silver plating for minimal resistance. Additionally, our snap-action JN15 Earthing Switches provide reliable safety grounding, fully compliant with IEC 60694 standards.
