Designed for both polymeric (XLPE, EPR, HPTE) and paper-insulated cables, they accommodate a wide range of conductor sizes and cable diameters, making them versatile for diverse applications.
Lovix straight cable joints
The LoviX R range provides a fast, reliable, and maintenance-free jointing solution for polymeric insulated cables. Designed for simplicity and safety, the LoviX system uses an innovative resin insulation to create a robust joint body offering excellent dielectric strength and moisture protection.
Features: Compact, factory-tested cold-shrink joints with excellent mechanical and electrical performance.
Applications: Suitable for medium-voltage cable connections in dry or standard environments.
Construction: Pre-expanded silicone body on a removable core for quick, tool-free installation.
Standards: Rated for 6–36 kV cable systems; tested to international utility standards.
Customisation: Available for straight and transition joints in various cable types.

Lovisil straight through cable joints
The LoviSil system uses liquid silicone technology to ensure total encapsulation of cable connections. Its self-healing insulation properties and environmental resilience make it a preferred choice for critical infrastructure.
The LoviSil range is based on Lovink’s liquid silicone insulation technology, providing a self-healing, reusable, and environmentally resilient insulation system. Unlike conventional cold-shrink or resin systems, LoviSil joints are filled with a unique silicone liquid that permanently surrounds the cable connection.
LoviSil ideal for installations in wet, flood-prone, or corrosive environments, such as renewable energy connections, coastal networks, and utilities with strict reliability standards.
Features: Compact, factory-tested cold-shrink joint with excellent mechanical and electrical performance.
Applications: Suitable for medium-voltage cable connections in dry or standard environments.
Construction: Pre-expanded silicone body on a removable core for quick, tool-free installation.
Standards: Rated for 6–36 kV cable systems; tested to international utility standards.
Customisation: Available for straight and transition joints in various cable types.
