Product Introduction

The 12kV Ring Main Unit (RMU) SF6 Gas RMU is an advanced, compact, and reliable solution for medium voltage power distribution networks. Intended to satisfy the thorough needs of modern electrical grids, this unit assumes a urgent part in guaranteeing the effective and safe distribution of electricity.
The SF6 gas-insulated RMU is prestigious for its excellent dielectric properties, which give predominant insulation and arc-quenching abilities. This settles on it an ideal decision for metropolitan and industrial applications where space is restricted and unwavering quality is fundamental.

The RMU consists of multiple switches that can isolate faults in the network, thereby enhancing the stability and resilience of the power supply. The unit's modular design considers simple incorporation into existing frameworks and offers adaptability for future developments. Each module can be equipped with circuit breakers, load break switches, and fuse switches, depending on the specific requirements of the application.

Incorporating SF6 gas technology ensures that the RMU operates safely under various environmental conditions, with minimal maintenance requirements. The gas acts as an effective insulator, reducing the risk of short circuits and electrical faults. Besides, the sealed nature of the unit forestalls the entrance of dust and dampness, accordingly expanding the life expectancy of the inside parts.
