Euromold 480TB Tee Connector 11kV 33kV 42kV

Dead Break Elbow Connector

Euromold 480TB Plug-In Separable Tee Connector MV HV

Nexans Euromold 480TB elbow connectors (bolted tees) are used to terminate MV-HV XLPE/EPR (polymeric) insulated cables up to 42kV into Interface C Bushings according to CENELEC EN50180 and EN50181.

  • 1250A Connector Continuous Current Rating
  • 42kV Connector Maximum Voltage Rating

Euromold 480TB is a screened separable tee connector (bolted type) specified to terminate and connect medium/high voltage cables in the following voltage classes:

  • 6/10 (12) kV
  • 6.35/11 (12) kV
  • 8.7/15 (17.5) kV
  • 12/20 (24) kV
  • 12.7/22 (24) kV
  • 18/30 (36) kV
  • 19/33 (36) kV
  • 20.8/36 (42) kV

To select the correct Euromold 480TB connector for termination of MV HV power cables with copper wire screen or tape screen to Interface C bushings (1250 Amp) full cable specification with dimensional information is required – see the Euromold 480TB download opposite for complete technical specification of the elbow connector.

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

Euromold 480TB

The Euromold 480TB tee connector with 630A – 1250A current rating is designed for Interface C and covers voltages from 12kV to 42kV with a maximum conductor size of 300sqmm.

Euromold 480TB plug-in tee connectors can be supplied as a straight connector (450SR) or a coupling connector (800PB, 804PB or 809PB) and with surge arresters (800SA or 300SA) – all suitable for use with Interface C Compact type bushings on SF6 gas-insulated switchgear.

Euromold 480TB separable tee connectors are designed to connect all polymeric screened cables to suit CENELEC Interface Type C (630-1250amp) equipment bushings 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.

480TB connectors are suitable for terminating MV-HV cables with either “easy-peel” or bonded semicon screens – the 400 Series bolted 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.

Connector accessories include: dead-end receptacle, dead-end plug, stand-off plug and earthing plug for type C Compact interfaces.

Euromold 480TB Tee Connector 11kV 33kV 42kV - Design

Euromold 480TB Tee 11kV 33kV 42kV – Design

Separable tee connector comprising:

  1. Conductive EPDM insert.
  2. Conductive EPDM jacket.
  3. Insulating EPDM layer moulded between the insert and the jacket.
  4. Type C interface as described by CENELEC EN 50180 and 50181.
  5. Conductor contact.
  6. Basic insulating plug (with VD point).
  7. Cable reducer.
  8. Conductive rubber cap.
  9. Clamping screw.
  10. Earthing lead.

The thick conductive EPDM jacket provides a safe to touch screen which ensures safety for personnel, cables and electrical equipment in medium/high voltage installations. The screen break design enables cable outer sheath testing without removing or dismantling the connector.
