Three-Phase Dry Transformers 25-6550 kVA for Reliable Power Supply Applications

Transformers of TC series for voltage classes up to 10 kV are designed for power supply of general purpose consumers. Transformers are designed for operation in areas with temperate climate for operation under a canopy or indoors (version U3 according to GOST 15150).Windings are multilayer, cylindrical, made of aluminium (copper) wire of rectangular (round) cross-section with glass fibre insulation and impregnated with organosilicon varnish, with a surface varnish layer. The interlayer insulation is made of glass fibre reinforced plastic. Magnetoconductor of transformer with air-barrier insulation is made of anisotropic steel with electrical insulating coating.
