herein and as designated by the written instruction of the cable
manufacturer and termination kit manufacturer. Termination for
high-voltage cables shall be rated, and be capable of withstanding test
voltages, in accordance with IEEE Std 48. Terminations of single- and
multiconductor cables shall include the securing and sealing of the sheath
and insulation of the cable conductors, stress relief and grounding of
cable shields of shielded cable, and grounding of neutral conductors,
metallic sheaths, and armor. Adequately support cables and cable
terminations to avoid any excessive strain on the termination and the
conductor connection.

[Provide power cable joints (splices) suitable for continuous immersion in
water [and direct burial]. Make joints only in accessible locations in
manholes or handholes by using materials and methods specified herein and
as designated by the written instructions of the cable manufacturer and the
joint kit manufacturer. [Clearly mark joints buried directly in earth by
an identification slab.] Size connectors properly for the cable being
connected and crimp using a full circle compression tool.]

a.
Make medium-voltage joints by using a kit of one manufacturer and
with written approval of the manufacturer of the cable which is to
be spliced. Provide the [Contracting Officer] [Contractor's
Quality Control Representative] with a copy of the manufacturer's
instructions before jointing is started. Upon request, supply
manufacturer's design qualification test report in accordance with
IEEE Std 404. Joint design shall have been proof tested in
accordance with IEEE Std 404. Connectors for joint shall be
tin-plated electrolytic copper, having ends tapered and having
center stops to equalize cable insertion.
(1) Epoxy cast-type joint methods: Provide cast-type joint
insulation by means of a molded casting process employing a
thermosetting epoxy resin insulating material which shall be
applied by a gravity poured method or by a pressure injected
method. Provide component materials of the resin insulation in a
packaged form ready for convenient mixing without removing from
the package. Do not allow cables to be moved until after the
jointing material has completely set.
(2) EPR cast-type joint: Provide insulation by means of a molded
casting process employing an ethylene propylene-rubber (EPR)
jointing compound which results in an inseparable bond between the
