Insulation tube insulation material, is a general term, flame retardant, flexible, heat-resistant, easy to use, performance and reliability, if the insulation tube problems in need of repair should be aware of the following issues:

1, the Assembly must be in clean, dry conditions, preferably 40-50℃ temperature for Assembly. Capacitance core temperature higher than the ambient temperature 10-15degrees centigrade can reduce the effects of moisture, so it is best to assemble the front insulation pipe parts and capacitive heating core to 70-80deg c, keep the 3-4H, so as to exclude moisture on the surface, finish Assembly when the temperature has not been reduced as much as possible;

2, insulating tube on top of the seal. Seal at the top of the casing itself can be divided into casing seal and wear seal cable leads. Now that most of main transformer in substation of oil tank top with elastic corrugated sheets, together with compression spring, it to regulate the temperature. Assemble flexible corrugated board, of positive and negative pressure nut on the tube between the sealing ring and oil storage tank gasket must cooperate in order to prevent tension with corrugated plates in order to achieve the effect of sealing;

3, insulation tube wire is cable-type structure, if the terminal block at the top, seal tight between the conductive head, rain along the top of the casing strips, conductive and cables along the catheter into the internals of the transformer. Moisture enters transformers lead the roots will cause damp penetrate, causing power outages. To avoid this situation, and must be bolted firmly ensure the sealed.
