Dead Break Elbow Connector

Euromold 784TB Plug-In Separable Tee Connector MV HV 

Nexans Euromold 784TB elbow connectors are used to terminate MV-HV XLPE/EPR (polymeric) insulated cables up to 42kV into 700 Series Interface E Bushings with 5/8″ UNC copper bolted connections according to ANSI Interface type E.

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

Euromold 784TB is a screened separable tee connector specified to terminate and connect medium/high voltage cables in the following voltage classes:

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

To select the correct Euromold 784TB connector for termination of MV HV power cables with copper wire screen or tape screen to Interface E bushings full cable specification with dimensional information is required – see the Euromold 784TB 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 784TB

Euromold 784TB connectors are European equivalents to the Elastimold 700 Tee Connectors – this replaces the 775LR connection with the advanced specification feature of Voltage Detection Point and Grounding Lead.

These MV tee connectors can be used to joint or connect medium voltage cables with the correct mating part (Euromold 775CP-SC) and allows multiple connections to a single bushing by using the 850PB coupling connector.

The Euromold 784TB tee connector with 800A current rating is designed for Interface E and covers voltages from 12kV to 42kV with a maximum conductor size of 630sqmm.

Euromold 784TB plug-in tee connectors can be supplied with 750S1 bushings with aluminium or copper contact rods meeting the requirement of CENELEC HD 629.1  – all suitable for use with Interface E type bushings on SF6 gas-insulated switchgear.

Euromold 784TB separable tee connectors are designed to connect all polymeric screened cables to 700 series, ANSI Interface Type E (1250amp) equipment bushings with 5/8″UNC copper bolted connection.

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

Euromold 784TB Tee Connector 11kV 33kV 42kV - Design

Euromold 784TB Tee Connector 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 E 5/8″ interface as described by IEEE 386
  5. Conductor connector
  6. Basic insulating plug 858 BIPA (with VD point)
  7. Cable reducer
  8. Conductive rubber cap
  9. Stud/nut/washer 5/8″
  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.

Euromold 784TB Selection Table

For Screened MV HV TEE Connectors

Select the Euromold 784TB ordering part number which positions the cable most central to the minimum and maximum core insulation diameter, then substitute X using the table below, according to the conductor size (sqmm) and type (copper or aluminium). Order Euromold MT connector kit to enable termination of copper tape screened MV-HV cables in voltage range 11kV (12kV) to 42kV  – suitable for copper wire screened cables. Add a ‘K’ for use up to 24 kV, add an ‘M’ for use up to 36 kV, add a ‘P’ for use up to 42 kV.

The complete Euromold 784TB tee connector kit comprises the following components – cable lubricant, wipers, installation instructions and crimp chart.
