Electrical Insulation Polyester Shrinking Tape
Electrical insulation polyester shrinking tape is made of braiding with the special polyester fiber thread.
Electrical insulation polyester shrinking tape had good properties of chemical and insulation
So Electrical insulation polyester shrinking tape is suitable used as banding material of transformer.
electric machinery and electric appliance.Characteristics
Electrical insulation polyester shrinking tape is used to take the place of white gallon,
Electrical insulation polyester shrinking tape is easy construction and there is no need to be impregnated paint
electrical insulation polyester shrinking tape has High shrinkage rate and tensile strength, without loose and drop
Electrical insulation polyester shrinking tape is No pollute to transformer oil applications
Electrical insulation polyester shrinking tape is suitable to use as banding material in the transformer
mutual machinery, electric machinery, outside coil, lead line and so on.
