Scotch Electrical Semi-Conducting Tape 13 is a highly conformable, semi-conducting EPR (Ethylene Propylene Rubber) based high-voltage splicing tape. It is nonvulcanizing and shelf stable, with stable conductivity over a wide temperature range. Its conductivity is not affected, except by low-viscosity oils. The conductivity of cable semiconducting jackets is not affected by Scotch Electrical Semi-Conducting Tape 13.
FEATURES:
- Semi-conducting (low resistivity)
- Retains conductivity with strength
- Elongates easily to conform to irregular shapes
- Stable at elevated temperatures (130°C / 266°F)
- Compatible with most solid dielectric cable insulations and conductors
- Excellent resistance to cracking or checking from solvents, UV, or moisture
- Compatible with high-voltage splicing and terminating materials
- Usable for indoor or outdoor applications
- Meets requirement of ASTM-D-4388, Type IV
APPLICATIONS:
- To electrically round out high-voltage connectors and to bond to insulating materials to minimize electrical stresses
- Continue semi-conducting strand shielding found in solid dielectric (polyethylene, XLP, EPR, etc.) cables at 5 kV and above
- Provide shielding for cable joints on solid dielectric insulated power cables (shielded or concentric neutral)
- Replace semi-conducting layer beneath metallic shield of similar cablesin case of damage (screening)
- Make conductive portion of stress cone of power cable termination on solid dielectric insulated power cables
- Maintain positive connection between concentric neutral semi-conducting jackets of power cables and semi-conducting surfaces of plug-in units
- Establish a more positive contact between concentric neutral wires and pre-molded devices already installed with too much jacket exposed
- Round out bolted connections on insulated bus bars
