Control Rail Assemblies

Cabur control rail assemblies are designed to allow electricity providers and Users the possibility of easily checking on the measuring instruments, without interrupting current flow during control or during possible replacement of the instruments. ENEL has adopted a special colour system to identify phases according to the geographic areas where the rail assemblies will be installed. Every rail assembly is composed of an insulating base which holds the terminal blocks, in copper-zinc alloy, of the volt and amp meter circuits, and the devices for disconnection and short circuit operations. The base of the single-phase rail assembly is made of heat-hardened resin (black phenol resin). For the biand three-phase rail assemblies, the insulating base is made of Kelon (Keramic + Nylon).
