Transformer oil leakage depends on these points

Specification seals replacement process
For different models and different capacity of the transformer, whether it is flanged or threaded connection, replace the seals must be cleared before connecting surface dust and rust, clean the numbered seals after the seal on both sides coated with sealant ( generally use 609 polymer liquid sealant ) , a period of time until the sealant drying after solvent evaporation , the flange , screw connections are tight .

Improve installation process level , to eliminate because of improper installation caused leakage
Deformation of the flange interface is uneven or misaligned first correction interface dislocation can not be corrected serious cut can be re-welding flange must ensure parallel interface . Installation for compression gasket thickness of 1/ 3 or so .

Quick sealing glue stick plugging plugging
This method is used in transformers tiny leak , drip situation, the transformer radiator wall is thinner , and the method is inappropriate welding plugging leaks can be taken to deal with this method of plugging. Use glue stick plugging plugging , you must completely remove plugging parts of the oil , tamper seal tape patent leather , oxides, exposing the metal color. Then adjusted by the ratio plugging glue for sealing against leakage area until no leakage so far.
