Dead Break Elbow Connector

Euromold 430TB Plug-In Separable Tee Connector MV HV

Nexans Euromold 430TB elbow connectors, also referred to as bolted tee connectors,  are used to terminate MV-HV XLPE/EPR (polymeric) insulated cables up to 33kV/36kV into 400 Series Interface C Bushings with M16 bolted connections on the medium/high voltage electrical equipment according to CENELEC EN50180 and EN50181.

  • 630A Connector Continuous Current Rating
  • 36V Connector Maximum Voltage Rating

Euromold 430TB is a screened separable tee connector 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

To select the correct Euromold 430TB 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 430TB download opposite for complete technical specification of the elbow connector.

See the installation instructions for Euromold 430TB separable elbow connectors Type C Interface – the document covers (K) (M) 430TB/G connectors up to 33kV.

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

Euromold 430TB

The Euromold 430TB bolted tee connector with 630A – 1250A current rating is designed for Interface C and covers voltages from 12kV to 36kV with a maximum conductor size of 300sqmm.

Euromold 430TB plug-in tee connectors can be supplied as a straight connector (450SR) or a coupling connector (800PB804PB 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 430TB separable tee connectors are designed to connect all polymeric screened cables to suit CENELEC Interface Type C (630-1250amp) equipment bushings with M16 bolted connection up to 36kV.

430TB bolted tee connector can also be used to connect cables together using the appropriate mating part and parallel “piggy-back” connectors are also available to enable multiple connections to a single bushing.

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 andEuromold 430TB 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.

430TB connectors are suitable for terminating MV-HV cables with either “easy-peel” or bonded semicon screens – the 400 Series elbow connectors (bolted type) are specified for indoor cable termination applications, apply suffix (MWS) for outdoor cable connections where additional water-sealing and blocking mastic is required.

The following table enables the selection of copper tape screen earth kits for use with Euromold 430TB tee connectors – should you require any further assistance please do not hesitate to contact us.

Euromold 430TB Tee Connector 11kV 33kV - Design

Euromold 430TB Tee 11kV 33kV – 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 connector.
  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.

SELECTING EUROMOLD 430TB CONNECTORSEuromold 430TB

When the Euromold connector has been installed on the MV-HV cable the 430TB can then be mounted onto the Type C bushing. Provide complete manufacturers cable specification and actual bushing interface type to ensure compatibility of the Euromold connector with the medium/high voltage cable, switchgear or electrical equipment. Specification and design of the Euromold 430TB separable connector is available as a download opposite.

Euromold Connector Installation On Bushing

Clean and lightly lubricate both the 430TB connector and bushing interface on the medium/high voltage switchgear or transformer.

Push the connector on to the bushing to complete the termination of the cable. Insulating plug type Euromold BIPR without voltage detection point (for applications up to 24kV only can also be fitted.

Thorne & Derrick working with Nexans can arrange MV HV Jointer Training Courses for the installation of Euromold cable joints, terminations and connectors.
