Product Introduction

Product Features:

·The high-voltage ring main unit can optionally use LMG-12, LCG-12, SMG-12 and other series of ring main units. Flexible expandable combination schemes can be adopted according to terminal type or ring main type.

·The transformer can be dry-type, amorphous alloy or oil-immersed transformer, with a maximum capacity of 1250kVA.

·Low-voltage equipment can be configured according to power supply requirements using the State Grid standard SLVA low-voltage main incoming cabinet, feeder cabinet (outgoing circuits configured according to actual needs) and capacitor compensation cabinet. It can also adopt a reasonably laid out, compact and beautiful wall-mounted structure.

·The box-type substation can be equipped with station terminals and communication devices according to user requirements to realize automation "three-remote" functions, as well as high-voltage side DTU, low-voltage side TTU and other equipment.

·Space for energy metering can be reserved.

·Cable sealing plugs are added at the bottom of the high and low-voltage cabinets to prevent water vapor in the cable trench from entering the high and low-voltage cabinets along the cables. Condensation-proof cotton is installed on the inner side of the top of the high-voltage cabinet instrument room inside the box-type substation to absorb water vapor and prevent water droplets from dripping after condensation.
