Description / Abstract:
These standards apply to materials, constructions and testing of
asbestos-insulated, asbestos-vamished-cloth-insulated, and
asbestos-thermoplastic-insulated wires and cables which are used
for the transmission and distribution of electrical energy for
normal conditions of installation and service, either indoors,
aerial, underground or submarine.
Insulation thicknesses, formerly designated in terms of grounded and ungrounded neutral, are now designated in terms of cable insulation levels (see 3.3).
In these standards, units are expressed in the English system. For information only, their approximate metric equivalents are included.
