The beddng thickness shall comply with the vetoes specified in tables 4 to 13.
The tolerance for minimum thickness shall be 20% + 0.2mm.
Armour
The armour shall consist of a single layer of wires having nominal dimensions as giver in tables 4 to 13, as appropriate.
For single core cables, the armour sliali consist of aluminium wires.
For muiti-core cables, the armour shal consist of a single layer of galvanised steel wires.The armour shall be applied helically with a left-hand lay for cables having up to and mckxjkvg four cores. For multi core auxiliary cables the armour shall be applied helicalfy with a direction of lay opposite to that of the fine! layer of cures. except that for cable* which have been laid-up with alternating nght-and-left-hand lay the armour may ba applied with either a right-hand or a left-hand lay.
Wire armour shall comply with the following as appropriate:
(al The diameter of round armour wire shall fall within the minimum and maximum wire diameters specified in table 14 when measured rn accordance with sub-clause 2.1.4.3 of HD 605.
(bl The mass of zinc coating of galvanised steel armour wire shell not be less chan that given in table 14 when measured ki accordance with sub-clause 2.5.11 of HD 605.
(c) The steel wn shall be subjected to the wrapping test specified in sub-clause 2.3 2 of HD 605. and shal not break.
(dj The tensJe strength of aluminium armour wires shall not be less than liSN/mm* when measured in accordance with sub-clause 2 3.1.1 of HD 605.
(el The de resistance of the armour of the complete cable measured and corrected to 20е C shall not exceed the appropriate value given in tables 15 to 17 of thia part when measured tn accordance with sub-clause 3.1.2 of HD 605.
Joints In steel armour wire shall be brazed or welded and any surface irregularity shall be removed.
Joints in aluminium wires shall be made by cold pressure or fusion welding and all surface irregularities shall be removed.
Any joint in any wire shall be not less than Im from the nearest joint in any other armour wire in the complete cable.
4.3.6 Oversheath
The over shea th ehaR be an extruded layer of black synthetic material complying with the requirements for type ZM1 given in table 2. and sub-clause 2,4.4.4.
The ovaraheath thickness shall comply with the specified value in tables 4 to 13.
