Overview

Our MXSU medium voltage cable joint kit is based on a design using BSM mechanical connectors for conductor and wire shields, which are also supplied with the kit. The BSM mechanical connectors are compatible for aluminium and copper conductors of a wide range of sizes. 

To seal the connection and protect it from corrosion, the MXSU uses the heat shrink technology. It makes the MXSU perfectly suitable for underground power distribution applications. During the shrinking process the stored recovery force of the elastomeric layer is released and adds up to the recovery force generated by the heat shrinkable outer layers of the joint body. The resulting high compression forces as well as the perfect ability of geometrical adjustment provide tight electrical interfaces and a perfect seal against moisture ingress. The elastomeric properties of the inner insulation layer of the joint body representing any cable diameter compensation and adjustment resulting from the load cycling of the cable. At the same time, the two outer heat shrinkable layers provide a tight and rigid belt for the joint body representing a high level of mechanical protection against outer environmental interferences such as soil weight or pebble stones etc.

What is the advantage of using TE's BSM mechanical connectors?

  • Our wide range of mechanical connectors are suitable to fit and cover most conductor constructions and their tolerances.
  • They are suitable for aluminium and copper conductors.
  • They are easy to install thanks to the pre-set shear torque of the bolts, ensuring that the correct contact pressure in always achieved. 
  • They improve installation reliability thanks to the specially designed contact surface on the inside of the connector. It breaks up any conductor oxide layer and ensures reliable service over the entire
  • lifetime of the joint.
  • They have been tested in accordance with  IEC 61238-1 class A.

What are the tests performed on TE's MXSU?

  • CENELEC HD 629.1 S1 IEC 60502-4
    Raychem joints MXSU hvae passed all tests for XLPE insulated cables in accordance to CENELEC HD 629.1 S1 or IEC 60502-4 including impact
    tests at ambient and at low temperature. 
  • Additional tests reflecting future network operation
    Our MXSU were subjected to additional tests which are not part of any European standard but reflect future demands in modern network operation:
          - Overload operation of cables: More than 800 hours of electrical heat cycling at conductor
            temperatures of 130 °C with a voltage of 2.5 times the operating voltage U0.

          - Oversheath testing as the routine test method of cable networks: Voltage withstand tests
            between the screen wires and the water bath for 15 minutes at 15 kV DC and at 8 kV AC.

  • IEC 61238-1 class A
    Mechanical connectors used in Raychem joints MXSU, pass the requirements in accordance with IEC 61238-1 class A.
