Comprehensive detail drawing for power transformer installation at the Thar 2×330MW CFB Coal-fired Power Plant in Pakistan. This drawing includes essential connection specifications for high-voltage and low-voltage bushings, terminals, and flanges for operational integration.
Key Components:
– High/low voltage bushing terminal connection details (1:10 scale)
– Transformer grounding plate dimensions
– Enclosed bus duct connection flanges for low-voltage side
– Various valve flanges: DN25 ball valve (nitrogen injection), DN100 ball valve (oil drainage), 80mm butterfly valve (oil filtering)
– Foundation layout with jack positioning (1:25 scale)
– Bushing lifting diagrams showing vertical clearances
All measurements are in millimeters with precise dimensional specifications for flange mounting holes, terminal connections, and clearance requirements. The drawing serves as a critical reference for installation crews and electrical engineers during transformer placement and connection to the plant’s electrical systems.
