Established in 2005 by Jay and Saras, Jointing Services Ltd (JSLHV) stands as a testament to their unwavering dedication to excellence in high-voltage cable jointing. With over three decades of industry experience—rising from an electrician to becoming one of New Zealand’s most experienced high-voltage cable jointers—Jay has poured his heart and expertise into every aspect of the business.
At JSLHV, we combine cutting-edge technical proficiency with a deep commitment to reliability, safety, and precision. Our journey has been one of continuous growth, evolving from a small startup into a trusted name synonymous with exceptional jointing solutions.
In early 2025, Rudi Swanepoel and Ruben Rialon partnered with Jointing Services, enabling JSLHV to expand its capabilities. Ruben, a seasoned Power Technician with extensive experience in testing and commissioning, and Rudi, an Electrician with a strong background in managing high-voltage projects from start to finish, have brought valuable expertise to the team. Together, they enable JSLHV to offer a complete end-to-end service—from installation through to testing and commissioning.
Our mission is clear: to empower power networks with seamless connections, fortified by meticulous planning, rigorous testing, and an unwavering passion for innovation.
