3M Scotch 13 Tape

 

Scotch 13 Electrical Semi Conducting Tape is used for high voltage connections and provides cable shield continuation. 3M Scotch 13 Tape is a highly conformable, semi-conducting EPR (Ethylene Propylene Rubber) based high-voltage splicing tape.

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	Replace semi-conducting layer beneath metallic shield in various medium-voltage cable repairs and splices Electrically round-out high-voltage connectors and bond to insulating materials to minimize electrical stresses Round-out bolted connections on insulated bus bars Provide shielding for cable splices on solid dielectric insulated power cables Not to be used for electrical insulation
Specifications	Scotch Electrical Semi-Conducting Tape 13 must be based on ethylene rubber and be capable of operation at the emergency cable temperature of 130°C It must be usable without covering, both indoors and outdoors, in a highly stretched condition, without splitting or cracking It must be compatible with all common solvents, adhesives, and high-voltage splicing and terminating insulations Must not adversely affect semi-conductive cable jackets

 

 

3M Scotch 13 Semi-Conducting Tape Installation

Scotch 13 tape is usually wrapped in half-lapped layers. Highly elongate Scotch 13 tape when over wrapping cable connectors, terminal lugs and near edges of cable metallic shield, semi-conducting cable tape and semi-conducting cable jackets.

Note: Stretching Scotch 13 Tape increases its conductance and will not harm it in any way. Caution : Scotch 13 Tape is not oil resistant - it should not be used in splicing and terminating cables which contain oil or slippery compounds as part of dielectric such as PILC.
