  • 20.8/36 (42) kV

To select the correct Euromold 400TB connector for termination of MV HV power cables with copper wire screen or tape screen to Interface C bushings (630 Amp) full cable specification with dimensional information is required – see the Euromold 400TB download opposite for complete technical specification of the elbow connector.

See the installation instructions for Euromold 400TB separable elbow connectors Type C Interface – the document covers (K) (M) (P) 400TB/G separable tee connectors for Type C interfaces.

Euromold connectors should be installed only by competent jointers trained in good safety practices involving high voltage electrical equipment.

Euromold 400TB

The Euromold 400TB tee connector with 630A current rating is designed for Interface C and covers voltages from 11kV/12kV to 33kV/42kV with a maximum conductor size of 300sqmm.

Euromold 400TB plug-in tee connectors can be supplied as a elbow connector (400LB) and with surge arrester 400PB  – all suitable for use with Interface C Symmetrical type bushings on SF6 gas-insulated switchgear.

Euromold 400TB separable tee connectors are designed to connect all polymeric screened cables to suit CENELEC Interface Type C (630amp) equipment bushings with M16 bolted connection up to 42kV.

Designed to connect polymeric insulated cables with a copper wire screen but can be used on wire armoured, copper tape screen cables with the use of additional screen earth kits and accessories.

Euromold Kit MT is required for use with copper tape screened cables, typically BS6622 cable – this comprises 3 lengths of tinned copper earth braid and constant force springs, the earth braid includes a soldered end with stud hole for the earthing connection to the HSGK cable gland or grounding point.

400TB bolted tee connectors are suitable for terminating MV-HV cables with either “easy-peel” or bonded semicon screens – the 400 Series tee connectors are specified for indoor cable termination applications, apply suffix (MWS) for outdoor cable connections where additional water-sealing and blocking mastic is required.

Euromold Connector Installation

  • For MV HV cables with aluminium conductors wire brush the conductor before installing the conductor contact
  • Fit the contact on to the conductor
  • Position the crimp contact ensuring that the contact hole aligns with the bushing hole
  • Prior to crimping distance «Z» must be between 150mm and 160mm
  • Crimp the contact. Refer to the crimp chart for crimping sequence
  • After crimping distance «Z» must be between 155mm and 165mm
  • If necessary adjust the position of the cable reducer until distance «Z» is within the tolerance range
  • Remove any burrs left after crimping and wipe-off excess inhibitor using approved cable cleaning wipes


Euromold 400TB Connectors

  • Clean and lightly lubricate the inside surface of the 400TB connector housing and outer surface of the cable reducer
  • Check if the angle of the tee connector housing is correct relative to the palm of the crimp contact and, whilst preventing the cable reducer from further movement down the cable, gently slide the housing on the cable until it cannot advance any further
  • Make sure the cable reducer stays in place during installation and remove tape marker from the cable
