Product Introduction

  • The GCS type AC low voltage withdrawable switchgear is suitable for power plants, petrochemical industries, metallurgy, textile industries, and high-rise building power supply systems. It is especially applicable to large-scale power plants and petrochemical facilities with a high degree of automation and requirements for computer interface integration.
  • The equipment is used in three-phase AC systems with a frequency of 50 (60) Hz, rated working voltage of 380 (660) V, and rated current up to 4000 A. It serves as a low-voltage complete power distribution device for power generation and supply systems, motor centralized control, reactor current limiting, and reactive power compensation.
