Product Introduction

The KYN28A-24 (SDK1-24) armored removable AC metal switchgear (hereinafter referred to as switchgear) produced by the company is suitable for indoor three-phase 50/60Hz power systems with a rated voltage of 24kV, mainly used in power plants, substations, industrial and mining enterprises and high-rise buildings, as a way to receive and distribute electric energy and control, protect and monitor circuits.

KYN28A-24(SDK1-24) Armoured removable AC metal switchgear has a variety of functions to prevent misoperation, including preventing moving handcarts with loads, preventing grounding switches from closing the position circuit breaker, preventing live grounding switches, and preventing accidental entry into live compartments. The switchgear is equipped with VS1 and VN2 series mid-mounted high-voltage AC vacuum circuit breakers and sealed vacuum switches with excellent performance. The secondary circuit of the switchgear is equipped with reliable control and protection elements, and the bus adopts the insulation means of heat shrinkable insulation material or epoxy coating, optimizes the electrical shape, and the cabinet structure is compact, and the switchgear is a power distribution equipment with stable technology, stable performance, reasonable structure, convenient use, safety and reliability.
