11kV 24kV Connectors – Tee Connector MV HV Interface C – Prysmian Elascon

Prysmian Tee Connectors - 11kV 33kV Medium & High Cable Connectors (MV HV)

Prysmian Separable Tee Connector MV HV Interface C are suitable for the connection of polymeric MV cables to transformers and switchgear units in outdoor or indoor installations with a continuous current rating of 630A.

Suitable for single polymeric insulation (PE, XPLE, EPR) with aluminium or copper conductors with sizes between 35 to 300mm² – insulation voltage up to 24kV and operated when de-energized.

The separable tee connector meets CENELEC HD 629.1 S2 IEC 60502-4 — NF C 33-051 — NF C 33-001, Interface C meets CENELEC EN 50180 and EN 50181 and the metal conductor contact is compliant with IEC 61238-1 class A and HN 68-S-91.

Separable Tee Connector (Interface C 630A) – Diagram

Separable Tee Connector (Interface C 630A)

1. Multi-section mechanical conductor contact Al/Cu

Cover the section from 35 mm² to 300 mm². Copper or aluminium core. No need for special tools.

2. M16 Clamping screw

Steel silver-plated component threaded at both ends for attachment of the mating items: bushing, insulating plug, accessories. A uniform contact pressure is maintained for any combination.

3. Semi-conducting inner screen

Insert of semi-conducting EPDM enclosing the mechanical conductor contact connections so that ionization of the air remaining trapped inside is prevented.

4. Insulating body

Moulded from insulating EPDM, for integral reconstitution of insulation. It maintains a uniform contact pressure on the cable insulation and on the bushing interface, providing an excellent moisture seal.

5. Insulating plug

Epoxy component with a threaded metal insert for attachment to the clamping screw.

6. Cap

Moulded semi-conducting EPDM. Protects and earths the test point during normal use.

7. Moulded high permittivity reducer

Adapt the connector body to the different cables insulations diameters. Ensures watertight protection of the earthing device and enables the cable screen test.
