QEFG series environmentally friendly gas-insulated ring main unit

Product Overview:

The QEFG series environmentally friendly gas-insulated ring main unit is independently developed by Beijing Qingchang Electric Power. It uses a safe and environmentally friendly mixed gas as the insulating medium in the gas tank, replacing SF6 to solve the problem of SF6 gas leakage and pollution. With high operational safety, it serves as a core unit in the distribution network.

Due to the use of inert gases like nitrogen for insulation, the QEFG type environmentally friendly gas-insulated ring main unit has better environmental adaptability. This eco-friendly solution aligns with the development direction of China's power industry, making the QEFG type one of the most popular ring main units in China today. Compared to solid cabinets, the QEFG ring main unit is lighter and easier to transport and install. Its excellent intelligent design fully meets the current demands of China's smart grid, enhancing electricity safety, greatly improving daily work efficiency, and reducing the burden of manual management.

Product Features:

• Environmental Protection: The product does not use any harmful or greenhouse gases. Over 95% of the materials used are environmentally friendly and recyclable, with epoxy resin components accounting for less than 5%.

• Maintenance-Free: All high-voltage components are either gas-sealed or metal-enclosed, preventing rust and corrosion. The electrical components have a long lifespan and stable performance, achieving maintenance-free operation.

• Higher Reliability and Safety: The conductive parts of the main circuit are sealed in N2 gas, and the high-voltage live conductors are enclosed, making them unaffected by external environmental changes. This allows the equipment to operate in harsh environments for extended periods. It boasts high reliability with no risk of electric shock or fire. The excellent gas tightness means no gas replenishment is needed for 30 years.
