Description:

n  Product usage

SC (B) 10 epoxy resin cast dry-type transformer is manufactured according to standard of Dry-type Power Transformer, characterized with low performance loss, good energy saving effect, economic operation and no maintenance. In addition to high process structure metal, short-circuit resistance and lightning impulse level, it is still characterized with flame retardant, damp-proof, dust-proof and low noise, which can be connected to load center. It is widely used in high-rise buildings, airport, station, wharf, power plant, transformer substation, etc., especially applicable to be used in places with high fire protection requirements for flammable and combustible materials.

Standard transformer produced by the Company has no case, with the protection level of IP00, and case with the protection level of IP20 and IP23 can be provided as required by clients. Housing is made of such materials as common steel plate, corrosion resistant plate and aluminum alloy and then treated with acid pickling, phosphorization and plastics spraying according to the requirements of clients. Temperature control indicator and load recorder are installed on the low-tension side of the housing, convenient for observation and safe and reliable.

 

n  Product overview

Performance index of dry-type transformer produced by the Company meets various standards and it is demonstrated by users to have reliable operation and reach the national advanced level. This series of products are manufactured by using advanced foreign technology and design drawings and technical documents are complete, accurate and clear.
