Product use

SC (b) 10 epoxy resin casting dry-type transformer is manufactured according to the standard "dry type power transformer". The product has low performance loss, good energy-saving effect, economical operation and maintenance free. In addition to the advanced process structure, high level of short circuit resistance and lightning impulse, it also has the characteristics of flame resistance, moisture-proof, dust-proof and low-noise, which can go deep into the load center. It is widely used in high-rise buildings, airports, stations, wharves, power plants, substations, etc. It is especially suitable for installation and use in places with high fire prevention requirements such as inflammable and explosive.

The standard transformer produced by our company has no shell, and the protection grade is IP00. If the customer needs to provide the enclosure with the protection grade of IP20 and IP23. The shell can be made of ordinary steel plate, stainless steel plate, aluminum alloy and other materials according to the requirements of customers, and it can be treated by acid pickling, phosphating and plastic spraying. The temperature control display instrument and load measuring instrument are installed at the low pressure side of the shell, convenient for users to observe, safe and reliable.
