  Oil cooled transformers are made for use on various systems ranging from 11kv to 33kv. the basic construction of the CT is similar to CT of all voltage classes in that the core is placed in a tank mounted on top of the bushing and adequate paper insulation is provided on it. The secondary leads are run through the bushing to the secondary terminal box placed at the bottom of the bushing.   The advantage of this type of construction is that the transformer is dynamically more stable under short circuit conditions, the various forces on the primary conductors tending to balance on another. Requisite number of the primary turn are put on the core and the two ends are bought out for connection into the system. The primary ends are terminated on the terminals 30 mm dia 80mm long for easy connection into the system.In the case of two ratio current transformer in which the different ratios are obtained by primary reconnection, four primary terminals are brought out on the tank(corresponding to the two primary windings) and these are connected in series or parallel, by connecting links provided depending upon the ratio required. The transformers are fully sealed in construction and are supplied filled with required quantity of oil. Adequate allowance is made for expansion of oil due to temperature variations and as such a breather is considered unnecessary.

Single phase Industrial Control Transformers and general Purpose transformers.A Control Transformer is a transformer which supplies power to control and or auxillary equipment not intended for direct connection to the main circuit. Control transformers are specifically used to provide control supply voltages for the control circuits of AC motor starters.
