Underground cable jointer apprenticeship
They are specialised tradespeople who work with underground electrical power cables. Their primary responsibility is to install, repair and maintain underground cables, ensuring the safe and reliable distribution of electricity.
During your 4-year apprenticeship your training will focus on achieving a UET30821 Certificate III in ESI β Distribution Underground. Through on-the-job training you'll acquire a diverse set of skills and expertise, including laying, installing, and maintaining both low- and high-voltage underground cables, along with the installation and upkeep of electrical equipment.
Underground cable jointers spend a significant amount of time in restricted spaces like trenches, pits, and tunnels. They also work in a high-risk environment, so a safety-first attitude is essential.
Key responsibilities may include
Installation
Installing new underground cables in trenches, connecting cables to substations, and installing joint boxes or terminations.
Jointing and Termination
Joining or splicing together sections of underground cables. This involves carefully connecting the conductors in the cables using specialised techniques and materials to ensure a secure and reliable connection.
They also install terminations, which are devices used to connect cables to electrical equipment such as transformers or switchgear.
Testing and Commissioning
Carrying out tests to verify the integrity and performance of connections. This may involve conducting insulation resistance tests, high-voltage tests, and other electrical measurements to ensure the cables are operating within safety standards.
Maintenance and Repairs
Maintaining and repairing existing underground power cables. This includes identifying and locating faults or damage in the cables, excavating the area if necessary, and performing repairs or replacements to restore the integrity of the system.
Safety and compliance
Following strict safety protocols to prevent accidents and ensure compliance with regulations and standards. They may work with high-voltage equipment and must take precautions to protect themselves and others from electrical hazards.
Subjects to focus on
Maths
Sound basic addition, subtraction, multiplication, and division are needed for tasks such as measuring cable lengths, calculating quantities of materials needed, or determining costs.
Literacy
Competent language and writing skills are needed to understand documents such as safe-work method statements, wiring rules, standards, and drawings, and to complete documentation requirements.
If youβve already finished school
Completing a UEE22011 Certificate II in Electrotechnology (Career Start) is a great introduction to the industry. Itβs a good idea to complete a CPCWHS1001 Prepare to work safely in the construction industry, also known in the Northern Territory as a White Card.
