The design of 10kv class H dry-type transformer
Abstract: The dry-type transformer most in use in China is class F insulated encapsulated-winding type. Recently , the class H Nomex-paper-insulated dry-type transfor-mer appears on china market , whose outstanding elect romechanical performance , heat resistance , safety , environment protecting capability and compatibility are validatedthrough class F1 fire-resistant test , class E2 environment compatibility test and class C2thermal impulse test . As a result, it is worth spreading. The technical characteristicsof the class no-encapsulated-winding dry-type power transformer with NOMEX paper are introduced. Its cost is compared with the cast-resin dry-type transformer.
