Product Introduction

KYN28-24 metal armored withdrawable switchgear is a high-voltage switchgear suitable for indoor three-phase 50/60Hz, rated voltage 24kV power systems. It is mainly used in power plants, substations, industrial and mining enterprises, and high-rise buildings to receive and distribute electrical energy, and to control, protect, and monitor circuits.

Application

: Ferrous metallurgy

: Mineral development

: Power system

: EPC general contractor

: Compact cabinet structure
Adopting an assembled structure, the components have strong universality, occupy a small area, and are easy to produce and install.

: Five prevention functions
It has the function of preventing misoperation, including preventing the handcart from moving with load, preventing the circuit breaker from closing when the grounding switch is closed, preventing the grounding switch from closing when it is live, and preventing accidental entry into the live compartment.

: Multiple handcart configurations
Multiple types of circuit breaker handcart, voltage transformer handcart, lightning arrester handcart, isolation handcart, etc. can be configured, with good interchangeability and flexible operation.

: Reliable insulation performance
The main circuit adopts composite insulation, and the busbar adopts heat shrinkable insulation material or epoxy coating to optimize the electrode shape and ensure insulation performance.
