Primary–Secondary Integrated Ring Main Cabinet
Eco-gas RMU + DTU in one outdoor enclosure for urban cable rings: metering-grade line-loss acquisition, small-current earth-fault location, 128-pt/cycle fault recording and local fault isolation.
- Metering-grade line-loss acquisition: real-time bay energy metering incl. bidirectional active and four-quadra
- Small-current earth-fault judgment & location: multi-algorithm analysis of phase and zero-sequence CT data pin
- Fault recording: 128 samples per cycle, 4 cycles pre- and 8 cycles post-fault with remote-signal status, cycli
A cleaner, more reliable approach to MV switching
The HP-ELS series replaces SF₆ with environmentally friendly insulating media while keeping the proven safety and performance utilities expect from gas-insulated switchgear.
Product Overview
The primary-and-secondary integrated ring main unit adopts a new generation of eco-friendly gas-insulation technology together with primary–secondary equipment integration. It mainly comprises an eco-friendly gas-insulated ring main unit, a distribution terminal unit (DTU), an outer enclosure and connecting cables. It suits the incoming/outgoing line control and connection of urban underground cable ring networks and of hybrid underground-cable / overhead-line networks, realizing both ring and radial power supply.
