Category: Products
Summary: Specializing in the research and development, design, manufacture, processing, sales and installation of high and low voltage complete sets of electrical equipment, it is a professional manufacturer of smart grids, high voltage ring network cabinets, medium and low voltage switchgear A high-tech enterprise of electrical products such as cable trays, charging piles, and smart meters.

Keywords: switchgear, distribution box, ring network cabinet


KYN28-12 metal armored removable switchgear is suitable for three-phase AC 50Hz, 7.2-12kV single bus segmented power system, used to receive and distribute electric energy and control, protect and monitor the circuit. The switchgear conforms to IEC-298, GB3906, DL404 and other standards.



Fully metal armored and closed, can effectively prevent the accident from spreading. The low-voltage part and the high-voltage part are completely isolated.

The protection level reaches IP4X after the door is closed, which can effectively prevent the human body and external solids from approaching the charged body and moving parts, ensuring personal safety and reliable operation of the equipment.

The cable room has ample space for easy installation and maintenance of cables

Five-proof interlock is simple and reliable, and can effectively prevent misoperation

Vacuum circuit breaker is maintenance-free

The handcart has good interchangeability and is very convenient to replace the circuit breaker

Configure advanced relay protection device to realize power system automation

Fully assembled structure, beautiful appearance, high machining accuracy

Reliable wall installation and small footprint

The double-sided maintenance solution is convenient, practical and reliable

The handcart room, busbar room and cable room are all equipped with pressure release channels, which can ensure personal safety and prevent accidents from expanding when arcing occurs due to faults.
