Euromold 484TB 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

- 20.8/36 (42) kV
To select the correct Euromold 484TB connector for termination of MV HV power cables with copper wire screen or tape screen to Interface C bushings (630 Amp | 1250 Amp) full cable specification with dimensional information is required – see the Euromold 484TB download opposite for complete technical specification of the elbow connector.
See the installation instructions for Euromold 484TB separable elbow connectors Type C Interface – the document covers (K) (M) (P) 484TB/G connectors including 33kV/36kV Interface C switchgear/transformer connections up to 42kV.
Euromold connectors should be installed only by competent jointers trained in good safety practices involving high voltage electrical equipment.
The Euromold 484TB 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 630sqmm.
Euromold 484TB 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 484TB 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 24kV.
Piggy-Back Bushing Connections & Terminations
484TB 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 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.
484TB connectors are suitable for terminating MV-HV cables with either “easy-peel” or bonded semicon screens – 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.

SELECTING EUROMOLD 484TB 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 484TB separable bolted tee connectors are available as a download opposite.
Euromold 484TB Installed On Interface C Bushing
The connector and Interface C bushing should be cleaned and lightly lubricated before pushing the 484TB connector onto the bushing.
Clean and lubricate the insulating plug for the opposite side of the 484TB connector. Insert the plug in the connector and tighten assembly – use torque wrench with socket of 22 and tighten exerting 30 Nm (3 kgm or 22,1 foot-pounds) of torque. In order to achieve the correct applied torque to the separable connector ensure that there is no lubricant on the threaded parts.
