NS177: 11kV Joints (including Transition Joints) & Terminations -Polymeric Insulated Cables

Specifies the requirements for making joints and terminations on 11,000 Volt polymeric insulated cables in Ausgrid’s supply area. This Standard also specifies the requirements for transition joints from polymeric insulated cables to paper insulated cables, and for terminations onto network equipment and apparatus.

Scope

This Network Standard details the 11kV polymeric cable termination designs for underground to overhead (UGOH) connections, distribution transformers and switchgear found in Ausgrid’s currently designed distribution substations.

This Network Standard also specifies the construction requirements and joint kit details for the
following 11kV joints:-

• straight through joints for single-core and three-core polymeric insulated cables
• three-to-one joints for polymeric insulated cables
• tee joints for polymeric insulated cables
• stub tee joints polymeric insulated cables
• pot ends for polymeric insulated cables
• straight through transition joints (polymeric insulated cables to paper insulated cables) for single and three-core cables
• transition three-to-one joints
• transition tee joints
• transition stub tee joints.

Construction details for joints, terminations, and UGOH connections which are not covered in this standard shall be sought from Ausgrid as required.
