GCS series low voltage withdrawable type switch cabinet (short for "cabinet") is developed by united professional designers according to the requirements of related business departments,electric power users and design organizations. With high technical performance index, it can meet the demands of electric power marketing development, and compete with existing products. The equipment has currently been widely used in different places.
The cabinet is mainly applied in distribution system of power stations, oil industries, chemical industries, metallurgy industries, textile industries, and high-rise buildings. It also works in places, such as big power stations and petrochemical system requested by high degree automaticity and contacting with computers, as low-voltage power distribution unit in the system of three-phase ac frequency 50 (60)HZ,rated voltage 380 (400),V (660) V, rated current ≤5000A, to distribute and control electric power.
Design requirements meet the following standard : IEC439-1 Low voltage complete switch and control equipment, GB7151.1-2005 Low voltage complete switch equipment
