Euromold 400LR is a screened separable elbow connector specified to terminate and connect medium/high voltage cables onto Interface B bushings 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 (36kV)
- 19/33 (36kV)
To select the correct Euromold 400LR connector for termination of MV HV power cables with copper wire screen or tape screen to Interface B bushings (400 Amp) full cable specification with dimensional information is required – see the Euromold 400LR download opposite for complete technical specification of the elbow connector.
See the installation instructions for Euromold 400LR separable elbow connectors Type B Interface – download opposite.
Euromold connectors should be installed only by competent jointers trained in good safety practices involving high voltage electrical equipment.
Euromold 400LR elbow connector with 400A current rating is designed for Interface B and covers voltages from 11/12kV to 33/36kV with a maximum conductor size of 185sqmm.
Euromold 400LR plug-in elbow connectors can be supplied as a tee connector (400TE) and with plug-in type epoxy bushings – all suitable for use with Interface B type bushings on SF6 gas-insulated switchgear.
Euromold 400LR separable elbow connectors are designed to connect all polymeric screened cables to suit CENELEC Interface Type B (400amp) equipment bushings with 14mm Plug-In pins up to 36kV.
Connector accessories include: dead-end receptacle, dead-end plug, stand-off plug and earthing plug for type B Interfaces.

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.
400LR connectors are suitable for terminating MV-HV cables with either “easy-peel” or bonded semicon screens working at 33kV – the 400 Series elbow 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 400LR Specification
|Current Ir (A) – Interface B Bushings||Conductor sizes (sqmm)|
Separable elbow connector comprising:
- Conductive EPDM insert
- Conductive EPDM jacket
- Insulating EPDM layer moulded between the insert and the jacket
- Type B – 400 A interface as described by CENELEC EN 50180 and 50181

SELECTING EUROMOLD 400LR CONNECTORS
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 400LR separable connector is available as a download opposite.
Euromold Connector Installation
When the core insulation is removed from the medium/high voltage cable conductor and crimp contacts are installed the 400LR connector can be installed on the cable.
- Clean and lightly lubricate the inside surface of the 400LR connector and outer surface of the cable reducer
- Check if the angle of the Euromold elbow connector housing is correct relative to the palm of the crimp contact and gently slide the housing on the cable until it cannot advance any further
- The shoulder of the cable reducer must be flush or inside of the Euromold connector housing
- Insert the threaded end of the pin contact into the mating part and tighten until the hex. key has taken a set
Note: A connector/bushing mated combination should not be allowed to carry the full weight of the cable. Therefore it is necessary to clamp the cable immediately beyond the connector or cable screen adaptor.
