Linerless Rubber Tape

Product introduction of linerless EPR rubber insulating self-adhesive tape:

Linerless rubber insulating self-adhesive tape is a kind of high-voltage self-melting ethylene-propylene rubber insulating tape with good conformability, excellent insulating performance and stability. ; Unlined EPR self-melting tape with good electrical insulation performance, chemical corrosion resistance and temperature resistance.

Specifications of non-lined insulating self-adhesive tape:

1) Standard length of unlined insulating self-adhesive tape: 9m/10m

2)Standard width of  the tape: 19mm/25mm/38mm/50mm

3) Standard thickness of unlined insulating self-adhesive tape: 0.76mm

4)Other sizes of non-lined insulating self-adhesive tape (can be customized according to user needs)

Application of linerless insulating self-adhesive tape:

1,Unlined insulating tape can be used for main insulation recovery of solid dielectric insulated cables of 69kV and below

2,Unlined insulating tape can be used for busbar insulation protection of 35kV and below, overhead wire lead insulation protection

3,The gap filling and moisture-proof sealing at the electrical connection can be used without lining tape

4,Unlined insulating tape can repair and electrically insulate the sheath of intermediate joints and terminals

5,Electrical insulation and moisture-proof sealing of high-voltage and communication cables

6, the wire of the motor

Features and advantages of linerless insulating self-adhesive tape:

1. No lining, easy to use, self-adhesive, high and low pressure resistance

2. The linerless insulating self-adhesive tape has good compatibility with various materials and cables and wires

3. EPR self-melting tape without lining is convenient and fast: no heating, no open flame, no special tools, no need to disassemble screws, suitable for construction in various temperature environments, fast and convenient 4. High reliability of unlined insulating self-adhesive tape: excellent physical and electrical properties

5. Unlined insulating self-adhesive tape can be used for cable joints and terminal insulation, and its emergency overload temperature can reach 130 ℃

6. No lining, smooth unwinding

7. Wide temperature range and good weather resistance

6. How to use the self-adhesive tape without lining:

The linerless rubber insulating self-adhesive tape is easy to use, and the linerless self-adhesive tape is convenient to unwind. The tape is stretched to 3/4 of its original width. In key positions, the tape can be stretched to the verge of cracking for winding. This will not change its physical and electrical properties. In less critical parts, it is not necessary to pull so much. long. At the end, press the tail for a moment (squeeze the force in the direction), and finally wrap 2 circles of PVC adhesive tape on the outer layer as a mechanical protection layer under conditions. When the unlined insulating self-adhesive tape is on the cable joint above 15KV, the linerless rubber tape should be fully stretched throughout the joint winding process.
