We professionally manufacture a full range of products including high and low voltage switchgear components, distribution boxes and control boxes. We support a minimum order quantity of 1 unit, achieve 30-day fast delivery, and provide full-process product service support.




Core Insulation and Switching Unit: Adopts eco-friendly gas-insulated arc-extinguishing chambers, integrated with vacuum circuit breakers/load switches for high insulation strength.
Secondary Control and Protection System: Built-in intelligent relay protection devices and PLC logic control modules for remote monitoring.
Auxiliary Components: Equipped with microcomputer protection devices, ammeters, and indicator lights for status monitoring.
The KYN28-12 features a metal-enclosed armored structure with a "middle-mounted withdrawable trolley" design. It integrates power control, protection, measurement, and distribution functions.
Withdrawable Trolley: Components like circuit breakers can move flexibly between service, test, and maintenance positions.
Multi-compartment Separation: Divided into independent busbar, circuit breaker, and cable compartments to prevent fault spread.
Mechanical Interlock: Multiple devices restrict misoperations such as switching on/off under load.
