In this division:
"aerial cable" means any insulated or covered conductor or assembly of cores (with or without protective covering) that is above ground or water, suspended in the open air between 2 or more supports and forms part of an electricity network.
"aerial conductor" means any bare conductor that is above ground or water, suspended in the open air between 2 or more supports and forms part of an electricity network.
"aerial line" means an aerial cable, aerial conductor or aerial service line.
"aerial service line" means the final span or section of a low voltage aerial conductor of an upstream network that is connected to a point of supply.
"conductor" means a finished circular stranded assembly consisting of 3 or more metallic wires laid up together that has the specific function of carrying electrical current.
"covered conductor" means a conductor around which is applied a specified thickness of insulating material.
"insulated", for a thing, means the thing is surrounded by a nonconducting substance that provides resistance to—
(a) the passage of current; or
(b) disruptive discharges through or over the surface of the thing at the operating voltage; or
(c) the injurious leakage of current.
"U", for an aerial line, means its nominal voltage.
