Application
Full-sealed oil immersed power transformer has power rating of 30kVA~2500kVA suitable for the electric power transmission and distribution system with the voltage of 10KV and frequency of 50HZ, which is widely applied to high buildings, business center, subway, airport, station, mining enterprises, drilling platform, oil production platform and so on. This kind of power transformer is especially suitable for inflammable and explosive places and other severe places of high fire-proof requirement. Besides, it can also be used for powering and lighting in the residential area, shopping street, mining enterprises, village, etc.

Technical Parameter
Voltage grade: 10KV
Frequency: 50Hz, 60Hz
Phase No.: three phases
Power Capacity:30kVA~2500kVA

Advantage
1. Our power transformer is manufactured with foil winding and high quality insulating material and has a superior resistance to high temperature and voltage surges.
2. We adopt full-sealed design to keep the stability of oil.
3. The integral oil tank of our power transformer is composed of ripple-clip radiators and the surface of tank is treated with phosphating and antirust spraying, which is not easy to rust or damage and constant maintenance is not needed.
