The core coil assembly (CCA) is the winding assembly on the core. This is a vital part of the transformer also known as the active part. The construction of the CCA is significant from the performance point of the transformer. The CCA defines the insulation scheme, cooling, dynamic withstand capability, handling. Insulation scheme is categorized into major and minor insulation. Major insulation addresses the capability to withstand high voltages, isolation of the primary and secondary winding, clearances for voltage withstand. Minor insulation is the turn insulation, joint protection etc. Both the major and minor insulation are equally important for the successful operation of the transformer. Cooling is essential to prevent the thermal degradation of insulation. This enhances a transformer’s life. Transformers are cooled by convection or forced cooling. The cooling system is responsible for the free flow of oil in the assembly absorbing the heat generated by the windings and dissipating it. Transformers are designed to optimally excavate the heat from the windings through the gaps in the windings. This helps the transformer maintain the same levels of winding temperature and oil temperature during the loading cycle. The transformer experiences dynamic forces due to frequent loading and unloading. The sudden loading and withdrawal of load creates a tensile stress on the winding in the form of buckling forces or bursting forces. The construction of the CCA by providing sufficient radial and axial supports prevents the stress from causing any damage to the windings. Clamping of the windings axially is necessary to hold the assembly firmly. Clamping structure of the assembly has supports to route the tap and line terminals. Insulated vertical and horizontal strips of adequate thickness of a frame work to assist the routing of terminals. The assembly also provides facility to handle for ease of lowering the assembly into the tank and vice-versa.
