1. Model Description
Specification: 1.8mm × 50mm × 3m
● Color: Black
Appearance: Double layered structure (composed of high-performance elastic insulation material and waterproof sealant), rolled up
Working conditions: -40~80 ℃
2. Product Features
Good self melting property, suitable for special waterproof, moisture-proof, insulated and sealed places, easy to stretch and wrap, strong plasticity, very convenient for wrapping irregular joints, forming a squeezing and tightening effect; Can be used for outdoor operations, in conjunction with PVC tape.
3. Main applications
Waterproof and insulation protection at the joints of communication equipment base stations, antennas, feeders, etc; Waterproof sealing of the ends and joints of communication cables; Urban distribution network renovation, waterproof sealing insulation for connections and branch clamps of overhead insulated lines; Cable joint treatment for underwater submersible motors and geographical cables for urban street lights; Places where open flames cannot be used in mines, oil fields, chemical and power facilities.
4. Instructions for use
Clean the dust, oil stains, and other debris at the cable joints; Unfold the tape, peel off the isolation paper and stretch the tape until the width narrows to 1/2 to 3/4 of the original; Wrap and wrap the tape in a 1/2 overlap manner while maintaining a certain tensile strength; After wrapping, it is advisable to use your hands to squeeze the tape at the covered area, so that the layers are tightly adhered without air gaps for sufficient bonding (be careful not to break the tape with fingertips); To prevent the tape from being worn out in practical environments, PVC tape should be used as a complementary layer on its outer layer; If necessary, the waterproof tape can be divided into different specifications for use in other places.
