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

Ir. Faris obtained a B.Sc. in Engineering (Electrical) from Northern Arizona University and a Masters in Electrical Engineering from UNITEN, Malaysia. He joined TNB in 1991 where he worked on transmission lines and substations, regional control centre, SCADA and distribution network services. Since 2003, he has been working as Sr. Engineer/Technical Expert in Overhead Line Systems Design & Diagnostics, including MV aerial bundled cable systems. He is a registered Professional Engineer with Practicing Certificate with the Board of Engineers, a member of Institution of Engineers Malaysia and Honorary Secretary of CIRED Malaysia.

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.
