SC (B) 11 type epoxy resin cast dry-type power transformer is manufactured according to the standard "Dry-type Power Transformer". This product has low performance loss, good energy saving effect, economical operation and maintenance-free. In addition to advanced process structure, high resistance to short circuit and lightning strike, it also has the characteristics of flame retardant, moisture proof, dustproof and low noise, which can penetrate deep into the load. Widely used in high-rise buildings, airports, stations, docks, power plants, substations, etc. Especially suitable for installation and use in places with high fire requirements such as flammability and explosion.
The standard transformer produced by our company is without shell, and the protection level is IP0O. If customers need, we can provide shells with protection level of IP20 and IP23. The shell can be made of ordinary steel plates, stainless steel plates, aluminum alloys and other materials according to customer requirements, and processed for pickling, cleaning, and plastic spraying. The temperature control indicator and load recorder are installed on the low-pressure side of the shell, which is convenient for users to observe and reliable.
