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

33kV Connectors – Tee Connector MV HV Interface C – Prysmian Elascon

33kV Connectors

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

These 33kV connectors are suitable for single core polymeric insulation (PE, XPLE, EPR) cables with aluminium or copper conductors with sizes between 35 to 240/300sqmm – insulation voltage up to 33kV 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.

33kV Separable Tee Connector (Interface C 630A) – Diagram

Separable Tee Connector (Interface C 630A) 33kV

1. Multi-section Mechanical Conductor Contact Al/Cu

Cover the section from 35sqmm to 300sqmm. Copper or aluminium core. No need for special cable jointing 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. Semi-conducting Outer Envelope (Thickness 3mm)

Jacket made of semi-conducting EPDM. Its design provides relief of electrical stress as does a cable screen. Its connection to the cable screen ensures that the assembly is maintained at earth potential. It allows to evacuate the short-circuit currents.

5. 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.

6. Test Point

Electrically protected by a cap made of semi-conducting EPDM. A capacitive voltage divider allows the checking of absence of voltage before removing the connector.

7. Insulating Plug

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

8. Cap

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

9. Earthing Eye

For connection of the outer envelope to the metallic cable screen.

10. 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.
