SKGCS LV Withdrawal Power Distribution Cabinet


1. Overview

SKGCS (i.e. GCS) type LV Withdrawal Power Distribution Cabinet (hereinafter referred to as the device) is a new type of low-voltage withdrawable switchgear designed in accordance with the requirements of the Ministry of Electric Power, the majority of power users and design departments, in order to meet the needs of the growing power market for capacity expansion, computer interface, centralized power control, convenient installation and maintenance, and shortened accident handling time, based on the principles of safety, economy, rationality and reliability. The product has the characteristics of high breaking and connecting capacity, good dynamic stability, flexible electrical scheme, convenient combination, strong series and practicality, novel structure and high protection level. It can be used as a replacement product for domestic low-voltage withdrawable switchgear. Under the careful design and production of our company, this product has been continuously valued and affirmed by the power department and the majority of users. The main circuit scheme of our company's products has a total of 32 groups and 118 specifications, which are selected and compiled after soliciting the opinions of the majority of design, manufacturing, testing and use departments, including the needs of power generation, power supply and use and other users. The rated working current is 4000A, which is suitable for the selection of distribution transformers of 2500kVA and below. In addition, in order to improve the reliability and stability of power supply and meet the further needs of important power users such as power plants and cement plants, our company's technical personnel have further designed fixed-separation SKGCS products. In addition, capacitor compensation cabinets are designed to meet the needs of power supply and use and improve power factors, and reactor cabinets are designed considering the needs of comprehensive investment.

The device is suitable for power distribution systems in power plants, petroleum, chemical, cement, metallurgy, textiles and high-rise buildings. It is used in power supply and control systems with a high degree of automation and requiring computer interface, and is one of the more ideal low-voltage complete distribution devices.
