3.1 Cable joint categories
Cable join ts arc generally described by oneof thecategories that follow. These descriptive categories are provided only for convenience. They are not intended to cover all possible joint constructions. Some joint constructions may incorporate characteristics of two or more of the design categories listed.
extruded: A joint in which both cables are insulated with extruded dielectric materials rated 2.5 kV to 500 kV.
laminated: A joint in which both cables have a dielectric that consists of fluid-impregnated paper or paper/synthetic laminated tape, or varnished cloth.
transition: A joint that connects an extruded dielectric cable to a laminated dielectric cable.
3.2 Joint constructions
field vulcanized: A joint constructed in the field using externally applied heat and pressure to cross-link the joint polynwric materials thclcdric.
filled: A joint consisting of an outer shell that is filled with an insulating material to occupy the space around the individual insulated conductor(s).
heat-shrink: A joint provided to the end user as one or more expanded polymeric components extruded that undergo thermally activated recovery when heated to an appropriate temperature Production electrical testing cannot be performed on this type of joint because the stress control. insulation, and shield layers are not intrated during the rnoldin or extrusion process.
fingerprinting: Tests made to establish and subsequently confirm the properties of materials or components used in cable accessories. The samples used for the initial tests shall be from the same batch as those used in the accessory design tests. For the purposes of this standard, this only applies to field- fabricated joint ctrnstructions such as heat shrinkable, multi-component cold-shrink joints, field vulcanized, and taped joints.
sectionalizer: A sectionalizer is used to minimize induced current in the cable sheath/shield by electrically interrupting the semicunducting shield and conducting metallic sheath or shield of the two cable lengths that are joined together. Sectionalizers are prinniilv 1i4d on c.ihk .fl1. uwr.iIine at 60 kV and ah&w ai described in IEEE Std 575
spLice b: The component in a power cable joint kit that provides the dielectric insulation and nuy or may not contain the stress control and shielding as integral components.
4. Service conditions
Today’s Current cable joint designs are considered suitable for use under the following service conditions. However, it should be understood that this list was compiled based more on user and manufacturer experience than on specific requirements of this standard actual. It is not meant, in any way, to imply that any or all of these conditions are fully verified in this standard. For specific questions regarding these or other service conditions, the manufacturer should be consulted.
