CABLE JOINTS, TERMINATIONS, AND CONNECTORS
2.5.1
Medium-Voltage Cable Joints
Medium-voltage cable joints shall comply with IEEE Std 404. Medium-voltage
cable terminations shall comply with IEEE Std 48. Joints shall be the
standard products of a manufacturer and shall be either of the factory
preformed type or of the kit type containing tapes and other required
parts. Joints shall have ratings not less than the ratings of the cables
on which they are installed. Splice kits may be of the heat-shrinkable
type for voltages up to 15 kV, of the premolded splice and connector type,
the conventional taped type, or the resin pressure-filled overcast taped
type for voltages up to 35 kV; except that for voltages of 7.5 kV or less a
resin pressure-filled type utilizing a plastic-tape mold is acceptable.
Joints used in manholes, handholes, vaults and pull boxes shall be
certified by the manufacturer for waterproof, submersible applications.
2.5.2
Medium-Voltage Separable Insulated Connectors
**************************************************************************
NOTE: Separable connectors shall not be used in
manholes (except where necessary for reason of
clearance at an airfield). Loadbreak types are
rated by IEEE Std 386 up to 200 amperes. Provide
test points only where the local facilities engineer
indicates that it is an operational requirement. If
loadbreak separable connectors are allowed as
substitutes for conventional permanent splices, the
Using Agency often presumes that the intent was that
they could be used for "switching functions." This
type of generic approach can allow unsafe
configurations with inadequate space for proper
hookstick operation. This substitution is
prohibited.
**************************************************************************
Separable insulated connectors shall comply with IEEE Std 386 and shall be
of suitable construction or standard splice kits shall be used. Separable
insulated connectors are acceptable for voltages up to 35 kV. Connectors
shall be of the loadbreak type as indicated, of suitable construction for
the application and the type of cable connected, and shall include cable
shield adaptors. Separable insulated connectors shall not be used as
substitutes for conventional permanent splices. External clamping points
and test points shall be provided.
2.5.3
Low-Voltage Cable Splices
Low-voltage cable splices and terminations shall be rated at not less than
600 Volts. Splices in conductors No. 10 AWG and smaller shall be made with
an insulated, solderless, pressure type connector, conforming to the
applicable requirements of UL 486A-486B. Splices in conductors No. 8 AWG
and larger shall be made with noninsulated, solderless, pressure type
connector, conforming to the applicable requirements of UL 486A-486B.
Splices shall then be covered with an insulation and jacket material
equivalent to the conductor insulation and jacket. Splices below grade or
in wet locations shall be sealed type conforming to ANSI C119.1 or shall be
waterproofed by a sealant-filled, thick wall, heat shrinkable,
thermosetting tubing or by pouring a thermosetting resin into a mold that
surrounds the joined conductors.
