SG (B) 10-H dry series

Overview of SG (B) 10-H dry series

SG (B) 10 series non-encapsulated dry-type transformer is a new product with environmental protection, energy saving and safety concepts. It uses Nomex insulation material produced by DuPont of the United States. The high and low voltage windings of the transformer are made of oxygen-free and high-conductivity electromagnetic copper wires. , The carefully designed continuous, foil-type structure and vacuum pressure dipping process (VPI) make the partial discharge small, and there is no cracking, and no decrease in insulation level during the entire life cycle. The overall vacuum impregnation and high-temperature curing treatment, and the use of high-strength ceramic support, has a good ability to withstand sudden short-circuit current. The maximum allowable operating temperature of the H-class heat-resistant insulation-grade coil is 180 ° C, and the main insulation material is C-grade (heat-resistant up to 220 ° C) Nomex paper, leaving sufficient design margin. The product can be installed in dirty and humid environments and areas with high fire protection requirements and heavy loads. It has the characteristics of high reliability, good safety performance, good environmental protection, small size, light weight and beautiful appearance. Widely used in high-rise buildings, airports, subways, terminals, petrochemicals, densely populated areas, nuclear power plants and other places.
