The range

Cable terminations seal and insulate the end of a power cable and control the electrical field where the screen is cut, so the cable can connect safely to switchgear, transformers and overhead lines. The range covers low voltage and medium voltage cables in heat shrink and cold shrink designs.

Customised designs available. If your project needs ratings, features, design requirements or arrangements outside the standard range below, we design and manufacture to your requirements and application. This includes cable sizes, diameters and lengths beyond the standard sizes shown, which we make to order.

Heat Shrink Terminations for LV Cables

Termination kits for 0.6/1 kV cables with one to five cores, with or without armour, including 3+1, 4+1 and 3+2 core cables. An adhesive coated breakout (a trifurcating breakout on three core cables) seals the cable crutch, and heat shrink insulation tubes seal between the lug and the core insulation. For single core cables only an insulation tube is needed.

Heat Shrink Terminations for MV Cables

Indoor and outdoor terminations for screened single core and three core polymeric insulated cables from 6 to 36 kV, in standard cross sections from 25 to 1200 mm², with larger sizes made to order. Stress control tube and stress relief mastic grade the electrical field at the screen cut, and anti tracking tubes and rain sheds give the creepage distance each voltage class needs. The same universal system also suits paper insulated cables.

Cold Shrink Terminations

Silicone rubber terminations for 0.6/1 kV cables and for medium voltage cables from 6 kV to 36 kV, indoor and outdoor. They are supplied pre expanded on a removable core and shrink onto the cable when the core is pulled out, with no heat, flame or special tools.

Trifurcating Kits for Three Core Cables

Termination kits for three core cables, low and medium voltage, indoor and outdoor, split the cable into three cores and include the adhesive coated trifurcating breakout that seals the crutch. They are supplied as standard kits or complete kits with lugs, in heat shrink and cold shrink.

Standard Kits and Complete Kits

Terminations are supplied as standard kits, or as complete kits with lugs. We can also supply lugs, connectors and a solderless earth connection system for armoured cables with the kit, and terminations and components for other cable types are available on request.

Specifications

Standard sizes and typical values are shown for each type. Larger, smaller and special sizes are made to order, and final selection is confirmed for each project.

Customised designs available. If your project needs ratings, features, design requirements or arrangements outside the standard range below, we design and manufacture to your requirements and application. This includes cable sizes, diameters and lengths beyond the standard sizes shown, which we make to order.

Design and performance

Terminations built to keep cable ends reliable in service.

Electrical Stress Control

Stress relief mastic with a stress control tube, or a moulded stress cone in cold shrink designs, smooths the electric field at the end of the cable screen, where failures start if it is left uncontrolled.

Anti Tracking Materials

Anti tracking insulation tubes, rain sheds and silicone housings resist tracking and erosion, so terminations keep their performance in polluted, coastal and wet conditions.

Moisture Sealing

Hot melt adhesive inside the tubes and an adhesive coated breakout over the crutch seal the termination against moisture, and the top of each cold shrink termination is sealed in three steps.

Earth Connection

The metal screen or armour can be connected to ground by soldering or by a solderless system. On cables with a wire screen, the copper wires are embedded in sealing mastic to prevent corrosion.

Weather Resistant

All materials resist UV and weathering, so the same termination families serve indoor switchrooms and outdoor pole and substation positions.

Type Tested Designs

Selected 15 kV and 33 kV terminations have been type tested to IEC 60502-4 by an independent high voltage laboratory.

Trained and Certified Installation

A termination is only as reliable as its installation. Poor installation is a significant cause of cable accessory failures. Heat shrink and cold shrink terminations must be installed by trained and certified jointers, following the manufacturer procedure for the cable type and voltage class, with correct preparation, stress control and sealing. Delstar arranges product training and certification for your installers and jointers, on site or before supply, so the work is done to the manufacturer procedure.

Sourcing and quality assurance

Our cable accessories come from one of the largest manufacturers in the world, with a very large global footprint and more than 20 years developing and making heat shrink, cold shrink and cold applied cable accessories, with its own materials laboratories and high voltage test laboratories. It is ISO 9001 and ISO 14001 certified, and selected 15 kV and 33 kV terminations and joints have been type tested to IEC 60502-4 by an independent high voltage laboratory. Delstar checks each order against your specification and delivers across New Zealand, Australia and the Pacific.

Lifecycle support

  • Installer training and certification: we arrange product training and certification for your installers and jointers on these terminations, before supply or on site, so installation meets the manufacturer procedure.
  • Specification and selection: we help match the termination type, voltage class, cable construction and cross section, noting that the final selection depends on the diameter over the insulation.
  • Complete kits: we can supply lugs, connectors and earth connection parts with the kits, so the full set for each termination arrives together.
