1. Overview

Low-voltage withdrawable switchgear is a new type of drawer-type switchgear, the structure type is assembled.The drawers of the same type can be interchanged, which is convenient for maintenance and installation. The technical performance of this product meets IEC39-85 standards,with protection level IP30, the breaking capacity of the main switch 80kA. It can be used for power conversion, distribution and control in circuits with rated voltage 380V or 660V, frequency 50Hz, rated current of main bus 3150A, feeder current 630A or below for power supply, power distribution of power distribution system and motor control centers, capacitor compensation in high-rise buildings, power plants, substations, petrochemical industry, factories, mines and enterprises, and can also be used for direct starting of motors.

The equipment meets the needs of the electric power market for capacity increase, computer interface, power centralized control, convenient installation, maintenance, shortened accident processing time, etc. The new type of low-voltage withdrawable switchgear is designed based on the principle of safety, economy, reasonableness and reliability, and the product has the features of high breaking and making capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong series utility, novel structure, and high protection level, etc.It can be used as a replacement product for the low-voltage withdrawable switchgear.
