Installation Techniques

Rounding Out Irregular Connections

Mould and pack Scotchfil electrical insulation

putty with moderate finger pressure to eliminate

voids and air spaces. The layers of Scotchfil will

fuse together into a homogeneous mass.

Insulating 600V Connections

For a 25mm connector, cut a 50mm piece of

Scotchfil putty and place in position.

Cut an identical piece and put at a 90-degree

angle to the first, but on the opposite side of the

connector.

Apply moderate finger pressure to form a perfect

mould.

Wrap with Scotch brand electrical tape Super 33+

or Super 88.

Creating 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 75mm from the jacket cutback.

Lay the ground wire along the cable jacket and

though the Scotchfil putty. Wrap several layers

of highly elongated Scotchfil putty around cable

and ground wire. Bind Scotchfil putty tightly

with several wraps of Scotch brand Super 33+ or

Super 88 vinyl electrical tape. The putty and

vinyl tape will make a seal though which resin

cannot flow.

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 stock in a clean, dry

place at a temperature of 21°C (70°F) and 40 to

50% relative humidity. Good stock rotation is

also recommended.

Availability

Scotchfil brand electrical putty is available in a

38mm x 1.5M roll from 3M and your local 3M

authorised electrical distributor.
