Note: If the operating environment exceeds the above range,please contact our company.

Box variable structure is divided into transformer body, high voltage room,low voltage room, testing room, switch operating room and fuse room six compartment, can be divided into” 目 “font or”品 ” font arrangement.

The product has compact structure and good sealing performance. The high-voltage load switch, fuse, transformer body and other components of the product are sealed in the oil tank. The oil tank adopts vacuum oiling process during encapsulation, completely removing the moisture in the transformer. The transformer oil does not contact with the atmosphere during operation, ensuring the insulation performance of the transformer.

The high voltage side adopts the terminal load switch and the fuse protection, the fuse is the full range of current limiting protection fuse.

The outgoing line of the high voltage side adopts the copper busbar structure supported by the high voltage dry sleeve to facilitate the connection of multiple cables. The low voltage outgoing can be directly routed or configured according to customer requirements.

Rated voltage grade: 35kV

Rated voltage on low voltage side:0.315KV(0.27kV、0.48kV)

Rated capacity: 500kVA-1600kVA

Rated frequency: 50Hz

Rated short-time power frequency withstand voltage(low-voltage side): 5kV

Rated short-time  power frequency withstand voltage(high-voltage side): 85kV

Rated lightning shock withstand voltage (full wave):200kV

Protection grade: Tank IP68, high and low voltage chamber IP44, IP54
