MV Cable Joints for Confined Spaces & Underground Trenches

The Lovink LoviX® R Compact Cable Joint is a straight-through MV joint designed for joining polymeric insulated cables (XLPE/EPR – 1-core) in distribution and industrial power networks. It’s built for repair, extension and new-build jointing where installers want a sealed, flame-free system with repeatable quality and strong environmental protection.

LoviX® R Technology

LoviX® R combines advanced cold-shrink insulation (silicone rubber with geometric field control) with a robust ABS housing that is filled with Protolin® resin. This construction creates a compact joint body that helps reduce pathways for moisture ingress, while also providing mechanical robustness for demanding locations such as ducts, trenches and direct-buried routes. Kits are supplied as complete sets with components packed in installation order to support efficient, consistent on-site build-up using minimal tools.

MV Network Classes (11kV / 33kV)

The LoviX® R range is available for common MV systems including 6/10 (12) kV and 12/20 (24) kV cable ratings, aligning with networks often referred to as 11kV and 33kV class (final selection depends on the installed cable system). Correct joint sizing is determined by the conductor cross-section and cable dimensions — including insulation diameter and outer sheath diameter — to ensure the right electrical interface and a secure, long-life seal.

  • Ranges shown apply to polymeric MV cables (XLPE / EPR) in 1-core constructions; suitability also depends on site conditions and the installed cable build.
  • If your project is described as 11kV or 33kV class, always match this to the actual cable system rating (e.g., 6/10 (12) kV or 12/20 (24) kV) and confirm selection against the project specification.
  • *R70 variants: availability for the largest conductor sizes may be subject to current production status — check lead times for your required cable dimensions.

Compact Cable Joint – Additional Information

LoviX® R Compact MV Cable Joints are built around a cold-shrink insulation system and a sealed joint body designed for long service life in demanding installations. Rather than relying on heat-shrink steps, LoviX® R uses silicone rubber insulation with geometric field control to manage electrical stress around the connector area. This supports consistent joint quality where performance depends on clean interfaces, controlled field distribution and the correct dimensional selection for the installed cable.

A key difference with LoviX® R is its compact protective housing: a robust ABS shell is filled with Protolin® resin to create a sealed joint body that helps prevent moisture ingress and adds mechanical robustness for ducts, trenches and direct-buried routes. Supplied as a complete kit with parts packed in installation order, LoviX® R is designed to reduce on-site variability, especially on projects where time, safety controls and repeatable workmanship are critical.

Cold-Shrink Silicone Rubber Insulation - LoviX R Compact MV Cable Joint

Cold-Shrink Insulation & Field Control

LoviX® R uses silicone rubber cold-shrink insulation with geometric field control to manage electrical stress around the connection area. This helps support reliable MV joint performance without heat-shrink steps, provided the correct size is selected and installed to specification.

ABS Housing Filled with Protolin Resin - Compact MV Cable Joint

Sealed Body for Moisture Resistance

A robust ABS housing is filled with Protolin® resin, forming a sealed joint body designed to help prevent moisture ingress and provide mechanical protection — particularly valuable for trenches, ducts and direct-buried installations.
