Power Distribution Equipment Manufacturer Overview

XBRELE stands as a comprehensive Power Distribution Equipment Manufacturer, specializing in the engineering and production of core components for 12kV, 24kV, and 40.5kV networks. Unlike suppliers limited to single categories, our ISO9001-certified facility integrates four critical product lines, offering a streamlined sourcing experience for global panel builders and utility contractors.

Our portfolio anchors on Vacuum Circuit Breakers (VCB), including indoor VS1 and outdoor ZW32 series, engineered for reliable fault interruption in high-voltage environments. We complement this with high-endurance Vacuum Contactors for frequent switching operations in mining and industrial motors.

Beyond switching, XBRELE manufactures essential Power Transformers, ranging from energy-efficient Amorphous Alloy types to robust Oil-Immersed units (S11/S13). To complete the switchgear ecosystem, we produce precision-molded Epoxy Insulation Components, such as Contact Boxes and Wall Bushings, using advanced APG technology. This integrated manufacturing capability positions XBRELE as a preferred partner for complete Medium Voltage transmission and distribution solutions.

/// Common Queries

Sourcing & Manufacturing FAQ

Is XBRELE a trading company or a direct manufacturer? +
XBRELE is a specialized Medium Voltage Power Distribution Equipment Manufacturer based in China. Unlike trading companies, we operate a fully integrated facility encompassing mold design, APG epoxy casting, and Vacuum Circuit Breaker assembly. We invite global clients to verify our manufacturing capabilities via factory tours or video audits.
What international standards do your switchgear components comply with? +
Our switchgear parts are strictly type-tested to ensure compliance with IEC 60694 and GB 3906 standards. For the core switching units, we adhere to the IEC 62271-1 High-voltage switchgear standard. Specific components like our SF6 Load Break Switches and Surge Arresters undergo rigorous testing at authorized institutes (XIHARI) to guarantee grid safety.
What voltage levels does your equipment cover? +
As a comprehensive power distribution equipment manufacturer, our portfolio covers the complete Medium Voltage (MV) spectrum, specifically 12kV, 24kV, and 40.5kV systems. This range supports most utility substations, industrial power plants, and mining applications requiring reliable vacuum switching technology.
How do you ensure the insulation quality of your components? +
Insulation quality is controlled at the source using advanced APG (Automatic Pressure Gelation) technology. Every batch of our Epoxy Contact Boxes and Wall Bushings undergoes X-ray flaw detection to identify internal voids, followed by Partial Discharge (PD) testing to ensure long-term electrical stability in your switchgear panels.
Do you offer OEM customization for special dimensions? +
Yes, we provide comprehensive OEM/ODM services for switchgear components. Our in-house mold workshop allows us to customize dimensions for Contact Boxes, Insulators, and Sensors to fit non-standard busbar geometries or specific cabinet designs (e.g., KYN28, UniGear, MVnex types).
What is your typical lead time for production? +
For standard models (like VS1 VCBs or standard contact boxes), we often maintain stock for shipment within 3-5 days. For customized or bulk OEM orders of power distribution equipment, the typical production cycle is 15-20 days depending on order volume.
How are the products packaged for export? +
We use robust, seaworthy packaging to prevent damage. Epoxy components are individually wrapped in foam and placed in reinforced cartons. Heavier equipment like Vacuum Circuit Breakers and Transformers are secured in wooden crates on pallets to withstand long-distance logistics.
What is your warranty policy? +
We stand behind our manufacturing quality with a standard 12-18 month warranty from the date of shipment. In the rare event of a defect, our technical team provides immediate support, including remote troubleshooting or free replacement parts for our switchgear components.
