At JointMaster, we provide high-performance MV (Medium Voltage) joints engineered to ensure reliable and safe connections for cables operating between 1kV and 36kV. Our MV jointing solutions are designed to withstand the demands of South Africa’s toughest environments — from industrial power plants and substations to mining and municipal infrastructure.
Our range of medium voltage cable joints includes heat shrink, cold shrink, and resin joint options. These solutions are developed to provide exceptional insulation, environmental sealing, and mechanical protection — essential for maintaining power integrity and minimizing downtime in electrical distribution networks.
Whether you require MV straight joints for splicing or transition joints for connecting cables of differing specifications, JointMaster delivers tested and certified products that comply with international standards (IEC, SANS, etc.). Our joints are compatible with both polymeric and paper-insulated cables, and we offer solutions tailored to copper or aluminium conductors.
We work closely with contractors, utilities, and OEMs to ensure that every MV joint solution meets site-specific needs. Each kit includes clear installation instructions, and we provide technical support and on-site training when needed.
