High Voltage Jointing

Our Services

Our services involve the safe and reliable termination of MV and HV cables, ensuring optimal performance and compliance with industry standards.


We also offer a full suite of cable and termination testing services to validate the performance of terminations, joints and the integrity of cables.


We work on a wide range of high voltage projects including substation commissioning, maintenance of transmission and distribution assets, process plant and electrical infrastructure.


Our high voltage capability includes high voltage testing of transformers, generators, motors and switchboards. When commissioning and maintenance testing of protection relays and schemes, our highly skilled field technical personnel use Omicron secondary injection test equipment to provide a wide range of diagnostic and testing services.

Specialist Jointing Services

Our personnel have a wealth of experience in jointing, from 11kV through to 132kV terminations and jointing.

Our Experience

Our jointers have worked on some of Australia's largest projects from Rozelle Interchange in Sydney and the construction of the MacIntyre Wind Farm in QLD, right through to working on network infrastructure.


We have experience in the mining, construction, renewables and infrastructure sectors.
