China Outdoor HV protective relays Manufacturer, Supplier, Factory

The GW5 outdoor isolation switch is a high-voltage electrical device designed to meet specific structural requirements. It consists of three independent single-phase isolation switches, making it a versatile and reliable option for various applications. The device complies with the standards outlined in the JB520-64 "AC High Voltage Isolation Switch" and features an additional grounding knife device for added safety. The CS-G manual operating mechanism is available in three variations: ungrounded, single-grounded, and double-grounded, providing users with options to suit their needs.

In recent years, with the progress of society, economy, and technology, engineering construction has become increasingly intricate. There is a rising demand for compact switch equipment that is low-maintenance and smart. Domestic and international switch manufacturers are working on 12KV 3150A Medium Voltage Electrical Switchgear Gas Insulation Switchgear, known as gas-insulated switchgear (C-GIS). This type of switchgear encases high-voltage elements like busbars, circuit breakers, isolating switches, and power cables in a shell with reduced gas pressure..

In recent years, with the growth of society and advancements in technology, engineering construction has become increasingly intricate. There is a rising demand for compact switch equipment that is easier to maintain and features intelligent functions. Manufacturers of switchgear, both locally and internationally, are focusing on developing 12KV 2000A High Current Gas Insulated Electrical Switchgear, which are also referred to as gas-insulated switchgear (C-GIS). These switchgear units house high-voltage elements like busbars, circuit breakers, isolating switches, and power cables within a shell that operates at reduced gas pressure.
