Suitable guide bars are provided inside the tanks to locate the position and to securely fix the Core Coil Assembly to the tank body and prevent any movement during transportation. A robust under base is provided with rollers unidirectional or bi-directional as required. Tanks and other metal clamping components are pretreated after shot blasting to remove rust and scales and then thoroughly cleaned and a coat of Zinc Chromate primer is applied to external surfaces and heat and oil resistant insulating lacquer varnish to internal surfaces. Additional cooling area is provided by pressed steel electrically welded radiators directly welded type or detachable type depending on the size of the transformer. Isolating shut off valves is provided for detachable radiators.
