High Voltage Heat Shrinkable Insulation Tape

High Voltage Heat Shrinkable Insulation Tape
1.10-35kv insulation protection
2Use to repair the protecting layer of the cable
HB1501

High Voltage Heat Shrinkable Insulation Tape
Features:
1.complex structure
2.the materials of inside layer begin to melt and the materials of outside layer begin to contract when heating, at the same time, to form good adhesion between the layers
3.resistantance to ultraviolet radiation
4.anti-aging
5.anti-mildew
6.excellent electric insulation
7.high insulation resistance and flame resistance and mechanical strength.

Applications:
1.anti-pollution flashover , condensation-proof ,corrosion resistance for substation switchgear bus
2.anti-foreign material overlap seam seal for ground wires or other charged body anti-foreign material overlap seam seal
3.in case of personal injury and death
4.srying of insulation and protection for in short-circuiting of small animals
5.the tape to the cable outer sheath to avoid physical damage, burn, or erosion and damage caused by organic solvent to provide a partial repair.

10-35kv insulation protecting
Use to repair the protecting layer of the cable.
Can provide sealing and insulation for cable termination and joints.
Transformer substation use this tape to protect the switchgear against dew and antisepsis
Avoid short circuit termination and joints.
