Testing & Certification Procedures for MV Premoulded Aerial Bundled Cable Straight Through Joints

The overhead MV distribution system at Malaysian TSO, Tenaga Nasional Berhad, consists of a bare line system (4500 circuit km) as well as an aerial bundled cable system (32,000 circuit km). The main reason for the decision to migrate from a heat-shrink to a pre-moulded straight through joint design for the latter system was to mitigate incidence of workmanship related failures. This presentation focuses on the certification procedure for these products installed on TNB’s 33 kV and 11 kV aerial bundled cable systems, including testing, field trial and post-implementation assessment. These procedures were developed to ensure all products and components are proven fit for use.
