AS/NZS 2373:2003 pdf download.Electric cables——Twisted pair for control and protection circuits.

The average thickness of insulation, determined by the method specified in ASINZS 1660.2.1. shall not be less than 1.5 mm and the

minimum thickness at any point shall be not less than I .30 mm.

NOTE: This requirement is designed to allow cables to withstand a voltage (under fault conditions) of 15 kV a.c. r.m.s. between the screen and the cores.

10 METALLIC SCREEN

10.1 General

The metallic screen shall be either a collective screen consisting of a tape or tapes applied helically over the collective

insulation or a moisture harrier sheath (see Clause II).

10.2 Collective screen application

For a single tape a minimum overlap of 15 percent shall be provided. For more than one tape a gap niay be used in each tape.

provided the following tape is positioned centrally over the gap in the underlying tape.

10.3 Collective screen malerial

The screen material shall consist of copper. brass or aluminium tape having a minimum thickness of 0.070 mm or aluminium/polyester laminated tape having a minimum aluminium thickness of 0.023 mm.
