multi-component cold-shrink: A joint provided to the end user as two or more components that are applied over a prepared cable and reduced in diameter without the use of heatby removal of thesupporting cores.Production clectrical testing cannot be performed on this type ofjioint because the stress control, insulation, and shield layers are not integrated during the moldingor extrusion process.See also: single-component cold-shrink.
premolded: A joint that is factory molded in the shape that it will take when installed. Installation isperformed by sliding thejoint over a prepared cable. The use of heat is not a part of the installationprocedure.Production electrical testing can be performed on this type of joint because the stresscontrol, insulation, and shield layers are integrated during the molding process.
single-component cold-shrink: A joint provided to the end user as an expanded single component device is applied over a prepared cable and reduced in diameter without the use of heat a by removal ofsupporting core.Production clectrical testing can be performed on this type of joint because thestress control，insulation，and shielding layers are integrated during the molding or extrusionprocess.See also: multi-component cold-shrink.
taped: A joint constructed in the field with the use of one or more tapes that are applied over thecable layers. Heat may or may not be applied as part of the installation procedure.Productionelectrical testing cannot be performed on this type of joint.
1) For joints rated 2.5 kV to 46 kV， Figure 1，Sequence 1， sample number 1through number 6,testing shall be performed on the smallest available conductorcable as well as the largest available conductor cable for which the joint isdesigned. To qualify a family of joints the smallest splice body in the family shallbe tested on the smallest available conductor size cable for which it is designedand the largest splice body in the family shall be tested on the largest availableconductor size cable for which it is designed.
i) For joints rated 69 kV to 500 kV,Figure 2,Sequence 1， sample number 1through number 4, testing shall be performed on the largest nominal conductorsize cable for which the joint is designed.
2) The short-time current test of 7.5 shall be performed on the largest available size
cable conductor for which thejoint is designed. When qualifying a family of joints, usethe splice body size that accommodates a cable size rated as close as possible to 40 kA.0.17 s.
3) For extruded dielectric cable joints rated 15 kV to 35 kV, the semiconducting shield
must meet the resistance and fault current initiation tests of 7.9 and can be performedon any conductor size.When qualifying a family of joints the test shall be performedon the particular splice body in the family which has the highest resistance from thecable entrance to the midpoint of the joint body, usually the housing for the smallestcable size in the family.Any conductor size in that housing may be used.
4)Connector thermal and mechanical tests of 7.11 shall be performed on appropriateconnectors, cable conductor materials and sizes.
