Product Description

SC(B)11 Dry Type High Voltage Transformer

General Description:
Dry type resin insulated SC(B)11, SC(B)10, SC(B)9 distribution transformers are widely used for power supply & distribution in industrial and civil occasions, to step down grid voltage (6-35KV) to line voltage 400V. The transformers are resin insulated, which is safe, non-pollute, flame proof and can be installed directly on the load centre, with the merits of free maintenance, easy installation, low operation cost, low loss and excellent humidity resistance.
Main application in: High-rise buildings, airports, terminals, power plants, transformer stations, residential areas or packages of various sites.
