Winding terminations onto bushings
Winding termination interfaces with bushings shall be designed to allow for repeatable and safe connection under site conditions without jeopardizing the in-service integrity of the transformer.
The winding-end termination, insulation system and transport fixings shall be so designed that the integrity of the insulation system is not easily compromised during repeated work in this area.
Allowances shall be made for accommodating up to 100 mm tolerances on bushing axial dimensions and the fact that bushings may have to be rotated to get oil level inspection gauges to face in a direction that allow easy inspection from ground level. In particular, rotation or straining of insulated connections shall be avoided during the fastening of conductor pads from the winding onto the termination surfaces of the bushing.
Suitable inspection and access facilities into the tank shall be provided to minimize the possibility of creating faults during the installation of bushings.
