CABLE TAPE
1. Cut cable to proper length leaving conductor sufficiently
long to extend into the terminal lug.
2. Remove braid, tape, and inner insulation and expose the
conductor end for a distance of one inch plus the length of
conductor to go into the terminal lug.
3. Attach terminal to conductor.
4. Taper the insulation as shown.
5. Remove the braid and tape, if any, six inches from the
lug, exposing the insulation. Leave one-half inch of original
cable tape extending beyond the cutback braid.
6. Apply the end seal using GE Irrasil” electrical tape. Ob-
tain a smooth wrapping but do not stretch tape more than
necessary.
7. Bind down end of braid and tape, if any, with lrrasil tape
as shown on drawing.
6. Apply two layers half-lap of GE Irrasile tapeover-all from
lug to exposed braid.

TERMINATION OF INTERLOCKED-ARMOR CABLE
Interlocked-armor cable is terminated by means of
specially designed cable fittings. These terminators
consist generally of mounting bracket, armor clamp,
and supporting base and bushing with various modifi-
cations available for special types of sealing.
INTERLOCKED-ARMOR, NON-SHIELDED CABLE
RUBBER-COVERED- Refer to Figure 35 for general
information concerning termination. For details, refer
to Figure 33. Note that rubber covered cable requires
taping only near the terminal and not back to the ter-
minator fitting.
VARNISHED-CAMBRIC- Refer to Figure 35 for gen-
eral information concerning termination. Note that
varnished-cambric cable requires taping back to the
terminator fitting since the individual conductors or
“singles” have no braid. See Figure 34.
INTERLOCKED-ARh,iOR, SHIELDED CABLE
Interlocked-armor, rubber-covered, and varnished-
cambric insulated cables are sometimes shielded at rat-
ings of 5kV and below. If they should be, proceed to
terminate as detailed for other types of shielded
cables. Refer to Figure 36.
