Good Parameter
1. Five pressures, no risk of leakage
The world's first technology to eliminate hidden dangers of gas leakage in products under pressure, and truly maintenance-free products
2. No SF6 greenhouse gas
The main insulation medium is natural air, and the greenhouse gas SF6 which is harmful to human body is not used, which is green and environmentally friendly.
3. No solid insulation wrap
Do not use solid insulation technical solutions that cause penetrating insulation failure and surface pollution flashover and creepage due to partial discharge
4. Atmospheric sealing
It adopts a fully sealed and fully insulated structure to improve the adaptability to the environment, and is stable, reliable, and effective during the entire life cycle.
5. Pressure balance device
The balance device with filtering function isolates the dust and dirt in the operating environment, and fundamentally prevents the occurrence of pollution flashover failures
6. Compact and small
Through atmospheric sealing technology, the product has the characteristics of high reliability, maintenance-free, compact and miniaturization, and completely replaces the traditional SF6 ring network cabinet.
Our RMU cabinets are widely used in urban ring network power supply systems due to their small space occupation, long life, maintenance-free, safe and reliable characteristics. The ring main unit in the cabinet can be equipped with SF6 ring main unit, environmental gas (N2) ring main unit, solid insulation ring main unit, and atmospheric air ring main unit. Automatic laser welding and helium leak detection equipment are used to ensure that the gas cabinet protection level reaches IP67. Cooperating with automated terminals, functions such as protection, remote control, telemetry, automation, and centralized line loss management can be realized. Factory strict performance testing and running-in test before delivery to ensure the quality of each product.
