Product features
Class H insulation:
The insulation and heat resistance grades of dry-type transformers include IB, F, H, C, etc. The heat-resistant temperatures are 130 ℃, 155 ℃, 180 ℃ and 220 ℃, respectively. DuPont new materials and new processes are used for this product. The insulation heat-resistant grade of SG (B) 10 dry-type transformer has reached Grade H, and the insulation heat-resistant grade of key parts has reached Grade C.

Security:
The SG (B) 10 new product is a dry-type transformer with upper limit safety performance. The insulating materials are not combustion-supporting, self-extinguishing, and non-toxic. Its combustible substances are less than 10% of the ring-gas cast products. At 800 ℃, the SG (B) 10 new product is more superior and benign in situations with high safety requirements, damp heat, and poor ventilation, such as electricity, subway, ship, chemical, metallurgy, etc.
Reliable:
The special coil design, process and material of SG (B) 10 new product make the product have better three-proofing performance (moisture-proof, mould-proof and smoke-proof), more able to withstand thermal shock, never crack and no partial discharge to produce a green system based on NOmex, and maintain good electrical and mechanical properties throughout the service life of the transformer. NOmex products are not easy to age, resistant to shrinkage and compression, and have strong elasticity, Therefore, it can ensure that even after several years of use, the coil of the transformer will remain tight and can withstand the short circuit pressure.
