EHV Joints – 132kV Extra High Voltage Cable Joints Using 3M Cold Shrink

132kV Cable Joints

132kV high voltage power cables are installed indoor or outdoor in open air in cable containment tray, cable trough and conduit or for direct burial underground in free draining soil or inside cable duct where no mechanical damage is to be expected.

132kV cables provide power for utilities high voltage underground distribution systems and in commercial buildings, industrial plants, power stations and substations.

3M high voltage 132kV cable joints have been designed for XLPE polymeric insulated cables up to 145kV Umax according to IEC 60840 with or without lead sheath and with or without copper screen wires – this includes super-clean XLPE insulation with bonded semi-conductive screens and either copper or aluminium conductors up to 1600sqmm.

3M offers 145kV Class high voltage cold shrink cable joints that are designed to fit a universal cable and can be kitted specifically to meet the high voltage application.

Silicone joint body is manufactured from Cold Shrink Technology.

The outer re-jacketing is installed using heat shrink tube or polyurethane 2 part Scotchcast resin or other.

Joint kits are available with, or without shield break for cross bonding and are based on the SC/SS 145-II cable joint body family.

The 3M High Voltage 132kV cable joints 98-AD xxx-1/x are in compliance to EU regulation 1907/2007/EC (REACH).

All components of the 3M Cold Shrink 98-AD xxx-1/x range are recommended to storage and stock rotation under temperature condition of -40°C up to 50°C.

The shelf life of the 3M EHV loaded inline cable joint body is specified as 18 month. All other components are specified to 36 month.

Jointing XLPE To Gas Compression & Oil Filled Cables

As utilities adopt modern technology polymeric (XLPE insulated cables) the process of 132kV asset replacement of aged gas compression and oil filled cable circuits demands transition type cable joints – we can support all your requirements for the jointing, termination and connection of 132kV high voltage cables.

Gas compression cables were generally installed from the early 1950s to the mid 1960s and oil filled cables were installed from the 1950s through to the late 1990s. From the late 1990s onwards a new type of non-pressurised XLPE cable was installed.
