Conductors for overhead lines. Aluminium conductors steel supported (ACSS)BS EN 50540: 2010 Conductors for overhead lines. Aluminium conductors steel supported (ACSS) BS EN 50540 is a European Standard which specifies the electrical and mechanical characteristics of ACSS conductors made of round or formed annealed aluminium wires and steel wires stranded in alternate directions, made of one or a combination of any of the following. Outer conductive layers: Annealed Aluminium wire as per requirements of Clause 5. Steel core:

Only samples of the same format type (several of which can be defined in the same part of ISO/IEC 19794) are intended to be interchangeable

steam at a pressure higher than atmospheric pressure is generated for use external to the system

d) Output circuits of frequency changers
