Overview
GCS withdrawable switchgear is suitable for power distribution systems in power plants, petro-leum, chemical, metallurgy, textile, high-rise buildings and other industries.
In large-scale development Power plants, petrochemical systems, etc. have a high degree of automation and require a computer interface. As a three-phase AC frequency of 50 (60) Hz, it is rated Distribution and motor sets in power generation and power supply systems with working voltage of 380V (400V), (660V), rated current of 4000A and below A complete set of low-voltage power distribution devices for medium control and reac-tive power compensation. It meets the IEC 439-1 international professional standard.
Performance Specifications
The design of the device meets the following standards
- IEC439-1 Low voltage switchgear and control equipment
- GB7251 low voltage switchgear
- ZBK 36001 Low voltage withdrawal switchgear
