Specifies the requirements for screened polyethylene (PE) insulated twisted pair control cables for voltages up to 0.6/1 kV, including a catenary support wire for aerial cables, intended for use in control, supervisory, protection and instrumentation circuits. It does not apply to cables used solely for telecommunication purposes.

This Standard specifies requirements for screened polyethylene(PE) insulated twisted pair control cables for voltages up to and including 0.6/1 kV. A catenary support wire is included for aerial cables.It applies to cables intended for use in control, supervisory, protection and instrumentation circuits. Control cables complying with this Standard may be used between power stations, substations or in industrial applications.It does not apply to cables used solely for telecommunication.
