THE 25 kV busline connecting the power cars of the Alstom-Fiat Pendolino trainsets is being developed by the Raychem Wire & Harness Division of Tyco Electronics Corp. Rigid polymeric terminations and bushings, together with a specially-developed spiral connector are used to transfer power between vehicles, where the restricted British loading gauge leaves a very small envelope between the catenary and the inter-car gangway.
The polymeric insulators offer a significant weight advantage over ceramic alternatives, saving up to 200 kg per vehicle. They are also impact resistant, create less aerodynamic drag and have a long creepage path to enhance performance in polluted environments.
