Note 1 to entry: Core cables can be of the following types: - equal lay cable, in which all layers have a common length of lay the direction of which is reversed in successive layers, - parallel core cable, in which cable is constructed with a central core of parallel-laid wires surrounded by one layer of helically laid wires,
- unidirectional cable, in which all layers have a common direction of lay, with increase in length of lay for each successive layer,
- unilay cable, in which all layers have a common length and direction of lay. Note 2 to entry: This entry was numbered 815-13-12 in IEC 60050-815:2015 |
