Data Sheet

3. Specification

The insulating putty must be in tape form, the thickness of which must be a minimum of 100 mils (2,54 mm). The tape must be a rubber based tape capable of being formed and molded with moderate finger tension at temperatures as low as 32°F (0°C). Neither the tape nor any of its components shall cause the corrosion of copper. The tape must be compatible with most synthetic cable insulation as well as other splicing tapes.

4. Engineering/Architectural Specification

All 2300 volt or less feeder connections, taps and splices, on wires larger than 6 AWG with irregular shaped

connectors, shall be first built up with electrical insulating putty to eliminate both sharp corners and voids. Enough insulating putty shall be used until good overall padding is provided. Compress putty to fill all voids and generally smooth up before applying electrical splice protection.

All 600 volt or less splices and terminations on wires

larger than 6 AWG with irregular shaped connectors shall be insulated with a minimum of 1/4 inch (6,3 mm) of electrical insulating putty. The entire connection must be covered with the insulating putty. The insulating putty must then be over-wrapped with a vinyl tape applied with the same tension as it has when it comes from the roll. This vinyl tape shall provide an uniform covering of at least four layers, half lapped in two directions.

5. Installation Techniques

To round out irregular connections, mold and pack Scotchfil Electrical Insulation Putty with moderate finger pressure, eliminating voids and air spaces. The layers of Scotchfil will fuse into a homogeneous mass. Over-wrap with two half lapped layers of Scotch Super 33+ or Super 88 Vinyl Electrical Tape.

To create a resin dam in resin pressure splices, wrap a layer of moderately stretched Scotchfil insulation putty around the cleaned cable jacket at a distance of 3.0 inches (7,6 cm) from the jacket cutback. Lay the ground wire along the cable jacket and through the Scotchfil putty. Wrap several layers of highly elongated Scotchfil putty around the cable and ground wire. Bind Scotchfil putty tightly with several wraps of Scotch Super 33+ or Super 88 Vinyl Electrical Tape. The putty and vinyl tape will make a seal through which resin cannot flow.

6. Shelf Life

Scotchfil Electrical Insulation Putty has a 5 year shelf-life (from date of manufacture) when stored under the following recommended storage conditions. Store behind present stock in a clean dry place at a temperature of 70ºF and 40-50% relative humidity. Good stock rotation is recommended.

7. Availability

Scotchfil Electrical Insulation Putty is available in 1 1/2 in x 60 in (3,8 cm x 152,4 cm) rolls from your local 3M authorized electrical distributor.
