7.0 Installation Techniques

HDT should be applied in half-lap layers

using moderate tension.

70 HDT Tape should be applied on all tape-

like terminations which will be operated

either outdoors or in areas subjected to

contamination or moisture. The following

procedure should be used:

If possible, connect the termination to its

final position. Otherwise, take care not to

damage the final overwrap of silicone tape

during installation. Overwrap the end seal

with several half-lapped layers. Overwrap

the entire termination with one additional

half-lapped layer. For upright termination,

begin from one inch on cable jacket and

end at the lug. For inverted termination,

end taping on the cable jacket. Wrap with

moderate tension (10 to 100% elongation).

Apply last lap with zero stretch. Press down

to avoid endlifting before fusion takes place.

70 HDT Tape can also be applied over the

exposed cable insulation and/or end seal

used in conjunction with molded (slip-on)

stress cones.

Techniques for the proper use of 70 HDT

Tape are contained in standard and special

prints available through the 3M Systems

for Splicing and Terminating Program.

This material may be obtained through

your local 3M Electrical Markets Division

representative.

NOTE REGARDING LINER REMOVAL:

To separate the liner from the tape when

starting a new roll, simply stretch the liner

and tape until the silicone tape breaks. The

liner will then separate at the point.

life (from the date of manufacture) when

conditions. Store behind present stock in

a clean dry place at a temperature of 70°F

and 40 to 50% relative humidity. Prolonged

exposure to temperatures in excess of 49°C
