Getting in
How to become a High Voltage Cable Splicer
Most splicers come up through a registered apprenticeship. The American Line Builders Apprenticeship Training program, for example, offers cable splicing as one of its dedicated tracks, and many utilities run their own splicer apprenticeships for workers who start as helpers or lineworkers.
Training covers cable construction, splicing kits from manufacturers, grounding, confined space entry for manholes and vaults, and the safety rules in OSHA's 1910.269 standard. Manufacturers of splice and termination kits offer product certification classes, and employers often require them. A high school diploma, mechanical aptitude and very careful hands are the usual starting points.

The work
What does a High Voltage Cable Splicer do?
High voltage cable splicers prepare, join and terminate the insulated power cables that run underground in vaults, duct banks and tunnels. A single splice involves stripping cable layers to precise dimensions, cleaning and shielding, and building up stress cones and insulation so the joint can carry high voltage for decades without failing.
Splicers work for utilities and electrical contractors on city distribution networks, substations, industrial plants and the collection systems of wind and solar farms. They also locate faults, cut out failed sections, test completed work, and install terminations where underground cable rises to overhead lines or switchgear.
Day-to-day tasks
- Prepare high-voltage cable ends by removing jacket, shield and insulation to exact dimensions
- Install splices, stress cones and terminations using manufacturer kits
- Enter manholes and vaults under confined space procedures
- Locate cable faults with test equipment and cut out failed sections
- Test completed splices and cable runs before energizing
- Install grounding and bonding on cable shields
- Read cable maps and circuit drawings to identify the correct circuit
- Pull cable through ducts with winches and rollers
Typical tasks, researched by NueCareer from the sources below.
Working conditions and hours
Splicers spend much of their time in manholes, vaults, trenches and substations, often in tight, hot or wet spaces that require confined space procedures. The work is precise and can take hours for a single joint. Emergency outage calls, night work in city streets and travel to project sites are common.
