Description

PLEXO is a plug & socket connection system for heating cables used in potentially explosive atmospheres. Installation time and expense are substantially reduced with this innovative method. Maintenance work or future modifications at the heating circuit can be carried out flexible.

The PLEXO connection system consists of a plug and socket. The heating cables and power supply connection cables are connected via safe springloaded terminals. The earth braid is connected via a metal disc with a spring creating the requisite pressure, eliminating any need for unravelling or twisting. A sophisticated sealing system offers safe and reliable protection against adverse weather conditions.

The flexibility of the system allows direct connection of the heating cable to a supply cable or an Ex junction box. A special connection sleeve is available for steel wire armoured (SWA) supply cables. Two similar heating cables can be joined to each other by means of a ‘splice’ plug and socket connection sleeve. The heating cable remote end termination can be equipped with plug-in contacts for future extensions of the heating circuit.
