Interface A Bushing Connectors

250Amps Cable Connectors for High Voltage Switchgear 

Interface A bushing connectors are screened separable connectors available as elbow or straight type design for the termination of medium/high voltage cables onto electrical equipment including MV-HV switchgear and transformers with bushings type A Interface (7.9mm pin type) – note these are deadbreak separable connectors, not loadbreak type.

The Prysmian range of Screened Separable Connectors are suitable for the connection and cable termination of Medium & High Voltage Cables with XLPE EPR insulation and either copper wire or copper tape screen cables, typically at 24kV into Gas Insulated Switchgear & Electrical Equipment with Interface A Bushings type.

Selection Guide

1. Select a Prysmian Kit Reference that corresponds to the cable diameter over insulation for the medium/high voltage cable.

*Model with adaptor

Example: 22kV single core copper 95sqmm cable with copper wire screen. Diameter over insulation is 23.9mm. Elbow type connector required.

Should you require any technical support for select the correct Cable Connector, Joint or Termination for use with Interface A Bushings please do not hesitate to call us.

2. Select earthing arrangement from the table below.

➡ Prysmian Separable Connectors include tee, straight and elbow connectors including supporting range of MV HV equipment bushings for Interface A, B and C – complete range of heat shrink and Cold Shrink or Cold-Fit joints and terminations are available for 11kV/33kV up to 66kV cables. To support and retain the installation of medium/high voltage power cables refer to the range of Prysmian cable cleats suitable for short-circuit protection and retention of cables located onto cable containment.
