Dry Type Transformer

Icon Powertech is a manufacturer and exporter of automatic voltage stabilisers, transformers with built-in stabilisers, rectifier equipment and special purpose transformers. The company offers Dry Type Transformers that are non-explosive, fire resistant, air insulated, and are cooled by natural circulation of air through ducts provide in the windings. High temperature and high dielectric insulating materials like glass fibre reinforced, Nomex insulating tapes are used in such a way that the entire assembly is capable of withstanding high electrical and mechanical stresses with good dissipation of heat causing low temperature rise within the prescribed limit of insulation class.

Standards: in general conforms to IS 11171-1985 for dry type transformers; windings made up of electrolytic grade, soft and bright annealed copper conductors covered with nomex insulating tapes; wound coils are preheated and impregnated with silicon varnish under vacuum pressure and undergo a curing cycle; low voltage coils are wound over glass fibre reinforced cylinder having high mechanical strength; high voltage coils are supported over yoke on glazed porcelain or resin insulators; core is made of CRGO silicon steel laminations duly annealed after shearing and assembled in mitred construction for low “no-load” loss; and the yoke frame has adjustable pressure plates to clamp and secure the coils adequately.

Rating: voltage grade up to 24 kV, capacity up to 5000 kVA.
