1. Manufactured by vacuum pressure impregnation (VPI) process, air-cooled or air-cooled.
2. High insulation level: Can reach H or C level.
3. Safe and reliable: the material is flame-retardant, self-extinguishing, fire-proof and explosion-proof.
4. Reliable performance: moisture-proof, mildew-proof, and smoke-proof, and can withstand thermal shock, never cracking, and no partial discharge.
5. Strong overload capacity: the coil structure has good heat dissipation, and the insulating material is not easy to age.
SG(B)10/SG(B)11 series H-class non-encapsulated dry-type power transformers are open-type dry-type transformers manufactured using the American UL-certified NOMEX paper insulation system and vacuum pressure impregnation (VPI) technology.
The voltage level is 20kV and below, and the product capacity ranges from 100 to 5000kVA.
It is widely used in high-rise buildings, commercial centers, industrial and mining enterprises, petroleum platforms, subways, tunnels and other places.
