24 Electrical Shielding Tape is an all-metal,
(Stretched and Unstretched)
Pass
open-weave, shielding braid tape in a flat, cable-like
form. It is conformable due to the open-weave knit
construction of two No. 36 AWG tinned copper wires.

Because of its construction, the tape interlocks
with the previous layer, thereby assuring a tighter
wrap (no solder bead is required)
The porosity of Scotch 24 Tape will permit
complete resin saturation when splicing
Usable for indoor and outdoor applications

Jointing (splicing) and terminating shall be done
according to the engineering print supplied by the
manufacturer of the jointing or termination materials
for the specific cable and approved by the specifying
engineer.
Alternate - the jointing and terminating engineering
drawing shall be compatible with the specific cable
or cables and approved for the specific voltage of
the cable.
