Wide Voltage Range
Supports low, medium, and high voltage cable systems, meeting requirements across different voltage levels and application scenarios.
A Cable Joint is a key component in power cable systems that connects two cable sections, ensures conductor continuity, and restores the electrical and mechanical integrity of the insulation, shielding, and outer sheath.
Voltecon's cable joint series covers various voltage levels and installation environments, meeting the connection requirements of different power systems.
Supports low, medium, and high voltage cable systems, meeting requirements across different voltage levels and application scenarios.
A standardized structural design enables the selection of compatible models for different requirements while ensuring a convenient and reliable installation process.
An optimized conductor connection, insulation restoration, and stress-control structure ensures long-term stable operation.
A multilayer sealing and outer-sheath restoration structure effectively prevents moisture ingress and protects against external environmental factors.
Designed for systems with voltages up to 1 kV, these joints are well suited for residential wiring and low voltage distribution networks.
Designed for power systems rated above 1 kV and up to 35 kV, these joints use reliable insulation, stress-control, and sealing structures.
Suitable for power systems above 35 kV, including transmission lines, substations, industrial power systems, and new energy applications.
Made of polymer materials, these joints shrink when heated and fit tightly around the cable surface to provide reliable insulation, sealing, and mechanical protection.
Use a pre-expanded elastomer structure held in an expanded state by a removable support core, without the need for tools like heat guns or torches.
Use factory-prefabricated insulation and stress-control structures, offering high installation consistency, stable electric field control, and reliable operation.
