Electrical ratings and test requirements of cable joints used with extruded and laminated dielectric shielded cable rated in preferred voltage steps from 2500 V to 500 000 V are established in this standard. In addition, test requirements for cable jacket and cable shield restoration devices are defined. A variety of common joint constructions are also defined. This standard has been designed to provide uniform testing procedures that can be used by manufacturers and users to evaluate the ability of underground power cable joints, and associated cable shield and cable jacket restoration components, to perform reliably in service.

This standard establishes electrical ratings and test requirements of cable joints used with extruded and laminated dielectric shielded cables rated in preferred voltage steps from 2500 V to 500 000 V. In addition, it defines test requirements for cable jacket and cable shield restoration devices. This standard also defines a variety of common joint constructions. Joints that connect more than two cables or connect cables with two different conductor sizes are not covered by this standard. However, manufacturers and users are encouraged to use appropriate parts of this standard to evaluate these joints.

The original standard provided manufacturers and users with a consistent set of guidelines for cable joints. This revision is needed to insure cable joint designs are consistent and appropriate for the latest industry-accepted cable designs and also to add qualification guidelines not fully addressed in the current standard. Purpose from Previous PAR - To provide a standard for the qualification and production testing of high voltage joints. This standard will specify uniform testing procedures, levels and requirements that can be used by both manufacturers and users to design and specify underground cable joints which will perform safely and reliably in ser...
