Product Introduction

  • The KYN28A-12(GZS1) indoor metal-clad withdrawable AC switchgear is a complete indoor distribution unit suitable for three-phase AC 50Hz, rated voltage 3–10kV systems. It can be used in single busbar or double busbar sectional systems and is primarily designed for power plants, substations, and industrial or mining enterprise distribution networks. The switchgear is used for receiving, distributing electrical energy, and controlling, protecting, and monitoring electrical circuits.
  • The switchgear adopts a metal-clad, centralized withdrawable structure, equipped with high-performance vacuum circuit breakers, and fully complies with modern grid requirements for high-voltage switchgear. It also features a complete “five-proof” interlock system to ensure safe and reliable operation.

Structural Features

  • The switchgear consists of several independent functional compartments:
  • Busbar compartment
  • Circuit breaker compartment
  • Cable compartment
  • Control and instrument compartment
  • Compartments are separated by metal partitions and include independent overpressure relief channels.
  • The cabinet has a protection level of IP4X, and compartments are IP3X.
  • All live parts inside the cabinet are insulated with high-performance insulating materials that are arc-resistant, heat-resistant, flame-retardant, low-toxicity, moisture-resistant, and have excellent mechanical and electrical properties, ensuring safe and stable long-term operation.
