33kV Connectors – Interface C Straight Connectors – Prysmian Elascon

33kV Connectors – Interface C Straight Connectors – Prysmian Elascon

Prysmian Separable Interface C Straight Connectors 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 and 35 to 240mm² – insulation voltage up to 24kV and 33kV and operated when de-energized.

The separable straight 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.

Straight connector MV HV Interface C – Features & Benefits

• No need for special tools – no heating, taping or filling
• Vertical, angled or inverted position
• No minimum distance between phases
• Energising may take place immediately after the connector is plugged into its bushings and dead end plug
• Unplugged connector must not be energised
• Supplied as a kit of 3 single connectors containing all the necessary components
• Shipping weight and volume (approx) of kit: 6kg /0.013m³

Separable Straight Connector (Interface C 630A) – Diagram

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. 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.
