Features

1. Compact structure with small volume, the volume is 1/3-1/5 of European style substation in same capacity. It reduces the floor space efficiently.
2. Whole sealing and full insulated structure ,no need insulation distance. This can protect personal safety.
3. High voltage wiring can use both in looped network and terminal with high reliability and flexibility.
4. The transformer is with excellent performance, low loss, low Noise, low temperature rise, high overload capacity, strong impact resistant ability and high anti-short circuit capacity.
5. Cable head with two type: 200A elbow connector and 600A “T” type fixed cable connector. Both can equip with all insulated Zn O lightning conductor. 200A elbow connector can use with load plug and with the function of insulation switch.
