Overview

The HXGN17-12 box-type fixed metal-enclosed switchgear (commonly known as a Ring Main Unit, RMU) is an AC high-voltage complete switchgear with a rated voltage of 12 kV and a rated frequency of 50 Hz. It is primarily used in three-phase AC ring networks, terminal distribution networks, and industrial power equipment to receive and distribute electrical energy. It is also suitable for installation in compact/prefabricated substations.

Structural Features

1. Adopts an all-assembled structure, which is lightweight and aesthetically pleasing. It can be freely combined and installed for unlimited expansion.

2. Can be equipped with either the FN12-10 pressure-type load break switch/combination unit or the FZN25-12 vacuum load break switch/combination unit, both with identical installation dimensions. Features compact size, maintenance-free operation, a three-pole linked mechanism, and a visible isolating gap.

3. The FN12-10 load break switch and combination unit offer flexible installation options, including left/right side mounting, front mounting, or inverted mounting.

4. Supports both manual and motorized operation, with remote control capabilities.

5. Equipped with a complete and reliable mechanical linkage and interlocking device, fully satisfying the "five-prevention" safety requirements.

6. Features linked, protective insulating shutters that automatically cover live contacts to ensure personnel safety.

7. Designed for front-operation and maintenance, allowing reliable wall-mounted installation.

8. The front door is fitted with an observation window for clear viewing of the internal components' operating status.
