jointing material and cable insulation. The molding process shall
include injection of molding material into the mold to ensure
void-free joints.
(3) Watertight taped-type joint: Consists of an approved
connector, self-fusing tape (splicing compound), self-bonding
semiconducting tape, tinned copper shielding tape or braid, and
plastic tape.
(4) Tape overcast-type joint: Watertight taped-type, overcast
with an epoxy resin construction for the cast-type, pressure
method. Provide joint suitable for the rated voltage of the
cable, to a limit of 15 KV.
(5) Vulcanized-type joint: Heat-pressure process of an approved
type and employing materials and equipment suitable for the type
and voltage of cables for which it is used. Materials used in the
jointing process shall be fully and permanently compatible with
materials in the cables. Provide joint suitable for the rated
voltage of the cable, to a limit of 5 KV.
(6) Heat-shrinkable joint: A uniform cross-section
heat-shrinkable polymeric construction consisting of a linear
stress relief system, a high dielectric strength insulating
material, and an integrally bonded outer conductor layer for
shielding. Replace original cable jacket with a heavy-wall
heat-shrinkable sleeve with hot-melt adhesive coating. Provide
joint suitable for the rated voltage of the cable.
(7) Cold-shrink rubber-type joint: Joint shall be of a cold
shrink design that does not require any heat source for its
installation. Splice insulation and jacket shall be of a
one-piece factory formed cold shrink sleeve made of black EPDM
rubber. Splice shall be packaged three splices per kit, including
complete installation instructions. Provide joint suitable for
the rated voltage of the cable, to a limit of 8.7 kV.
(8) Inline molded rubber-type joint: The concentric neutral (CN)
or jacketed concentric neutral (JCN) cable joint must meet the
requirements of IEEE Std 404 for the voltage rating of the cable
it is to be used on 15, 25 or 35 kV. It must be rated for
continuous operation at 90 degrees C, with an emergency overload
temperature rating of 130 degrees C. The joint shall be a slip-on
design made of molded peroxide cured EPDM rubber, with a separate
jacket over the splice and neutral wires consisting of an EPDM
rubber tube which has been factory stretched onto a spiraled core,
which is removed during installation. The splice shall be rated
for indoor, outdoor or direct burial applications.]

Cover the joined area with metallic tape, or material like the original
cable shield and connect it to the cable shield on each side of the splice.
