Distribution Tranformers

Oil-immersed conservator tank transformer Factories, hotels, Employs the latest technology with high quality enamel coated copper conductor windings utilized in both sides of the coil. Transformer mineral oil is used as an electrical insulation and to assist in heat dissipation inside the transformer tankField drying of transformer insulation T&D Guardian cambodia transformer tank oil technologyDuring the circulation period the oil is heated and passed through several filters to remove particulate matter. The oil also passes through a vacuum chamber where gas and moisture is removed. While maintaining vacuum on the transformer tank, the oil is then removed, exposing the solid insulation surface(s) to deep vacuum.Fire Protection in Substation Transformers T&D WorldWhere a firewall is provided between transformers, it should extend at least 1 ft (0.31 m) above the top of the transformer casing and oil conservator tank and at least 2 ft (0.61 m) beyond the width of the transformer and cooling radiators or to the edge of the containment area, whichever is greater.
