This is a 800kVA dry type power transformer. It is a three-phase transformer with F-class insulation (155℃), designed for indoor power distribution scenarios that require high safety, energy saving and reliability.The rated power of the step down dry type transformer is 800kVA with AN/AF cooling, the primary voltage is 10kV with ±2*2.5% tapping range (NLTC), the secondary voltage is 0.4kV , they formed a vector group of Dyn11.
Dry type power transformer use cast resin as the insulating medium, which provides excellent insulation and environmental protection. Combined with internal foil winding design, this construction greatly enhances dielectric strength and short-circuit resistance, guaranteeing dependable long-term operation for general distribution and special-use scenarios. Dry type power transformers support copper or aluminum windings with Class F or Class H insulation options; various enclosure grades are available to suit indoor and outdoor installation requirements. They are applicable to power transmission and distribution system,especially to heavy load centers and places with special fire protection requirements.
