3M 13 Scotch Electrical Semi Conducting Tape (3/4" X 15')

Description

Scotch Electrical Semi-Conducting Tape 13 is a highly conformable, semi-conducting EPR (Ethlyene Propylene Rubber) based high-voltage splicing tape. It is non-vulcanizing and shelf stable with stable conductivity over a wide temperature range. Its conductivity is not affected by Scotch Electrical Semi-Conducting Tape 13

Semi-Conducting (low resistivity)
Retains conductivity with strength
Elongates easily to conform to irregular shapes
Stables 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
Useable for indoor to outdoor applications
Meets requirements 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 (polyethyelene, 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 cables in 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 bus bars

Field Test

Scotch® Electrical Semi-Conducting Tape 13 can be checked for resistance with an ohmmeter. After elongating the tape 25% of its original width, probe points placed one inch apart on tape should measure 10,000 ohms or less. Figure 1 illustrates the type of results which may be expected in the field.

Characterictic and Test Data

Effects of Scotch® Electrical Semi-Conducting Tape 13 on resistivity of semi-conductive cable shield.

The Insulated Conductor Committee (ICC) has set a standard for compatibility of materials placed on shielded cables. When tested according to ICC Guide P1026, products in contact shield shall have a resistance measurement below ten ohm-meters. Scotch® Electrical Semi-Conducting Tape 13 complies with requirements of ICC Guide P1026.

Resistivity of cable semi-conductive shield overwrapped with Scotch® Electrical Semi-Conducting Tape 13 remained the same as, or lower than, that of the exposed shield (control). This test shows Scotch® Electrical Semi-Conducting Tape 13 does not significantly affect semi-conductive cable shields.

Engineering/Architectural Specification

Jointing (splicing) and terminating shall be done according to engineering print supplied by manufacture of jointing or terimnation materials for specific cable approved by specifying engineer

Alternate: Jointing and terminating engineering drawing shall be compitable with specific cable approved by specifying engineer

Installation Techniques

Scotch® Electrical Semi-Conducting Tape 13 is usually wrapped in half-lapped layers. Highly elongate tape when overwrapping connectors, terminal lugs, and near edges of cable metallic shield, semi-conducting cable tape and semi-conducting jackets.

Note: Stretching 13 Tape increases its conductance and will not harm it in any way.

Caution: Scotch® Electrical Semi -Conducting Tape 13 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 or VCLC.

Techniques for proper use of this conductive tape are contained in standard and special prints available through 3M Systems for Splicing and Terminating. Ask your local 3M sales representative.
