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