IEEE 404-2012 pdf free download – IEEE Standard for Extruded and Laminated Dielectric Shielded Cable Joints Rated 2500 V to 500 000 V.
3. Definitions
For the purposes of this standard, the following terms and definitions apply. The Autbortraias’e Diciaonwy q iEEE Standards Terms (nfl’ should be referenced for tenns not defined in thts clause,
3.1 Cable joInt categories
(‘able Joints are generally described by one of the categories that follow. These descriptive categories are provided only for convenience. They axe not intended to cover all possdsle )otnt constructions. Some joint constructions may incorporate characteristics of two or more of the design categories listed.
3.1.1 extruded: A joint in which both cables are insulated with extruded dielectric materials rated 2.5 kV to SOt) kV.
3.11 lamInated: A joint in which both cables have a dielectric that consists of fluid-impregnated paper or papersynthetic laminated tape, or varnished cloth.
3.13 traasltloti: A joint that connects an extruded dielectric cable to a laminated dielccttic cable.
3.2 Joint constructions
3.2.1 field sulcamind: A ,oint constructed in the field using esternally applied heat and pressure to crass- link the joint dielectric.
3.2.2 tilled: A joint consisting of an outer shell that is filled with an insulating material to occupy the space around the individual insulated conduetotis).
3.23 heat-shrink: A joint consisting of one or more espanded polymeric extruded tubes or molded parts that undergo thermally activated recovery when heated to an appropriate temperature.
3.2.4 inulti’eompunent coW-shrink: A joint provided to the end user as two or nsirc indisidual components, excluding the metallic splice, and the cable shield and jacket restoration components. that are applied 05cr a prepared cable and reduced in diameter without the use of heat.
3.23 pretnolded: A joint that is factory molded in the shape that it will take when installed. Installation is performed by sliding thc joint over a prepared cable. The use of heat is not a pan of the installation procedure.
3.2.6 sl.glr.coniponrnt cold-shrink: A joint provided to the end user as a single component device, excluding the metallic splice, and the cable shield and jacket restoration components.. that is applied over a prepared cable and reduced in diameter without the ute of heat.
3.2.7 taped: A joint consantcted in the held with the use of one or more tapes that are applied over the cable layers. Heat may or may not he applied as part of the installation procedure.
3.3 Other terms
3.3.1 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 constructions such as heat shrinkable, multi-component cold-shrink joints, field vulcanized, and taped joints.
3.3.2 sectionalizer: A sectionalizer is used to minimize induced current in the cable sheath/shield by electrically interrupting the semiconducting shield and conducting metallic sheath or shield of the two cable lengths that are joined together. Sectionalizers are primarily used on cable systems operating at 60 kV and above as described in IEEE Std 575. 10 4. Service conditions Current cable joint designs are considered suitable for use under the following service conditions. However, it must be understood that this list was compiled based more on user and manufacturer experience than on actual design testing. 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.IEEE 404 pdf download.
