IEC Conductors of insulated cables. Click here to sign up. Skip to main content.

European Committee for Electrotechnical Standardisation. The metallic sheath shall carry the short-circuit current in case of failure. The main insulation is cross-linked under high pressure and temperature.

IEC Tests on cable oversheaths which have a special protective function and are applied by extrusion. The conductor of high voltage cables can be made of copper or aluminium and is either round stranded of single wires or additionally segmented in 6207 to to reduce the current losses. Cable selection process This broad product range together with a application. These three insulation layers are extruded in one process. Single-end bonding or Cross-bonding Values apply for cables with rated voltages from kV to kV acc.
