Electricity Connection - UNTES URTP055 Instructions For Installation, Commisioning, Maintenance And Use

Sizes of power line cable to be spanned for the device panel should comply with the standards
(YVV(NYY)TS 212). The Nominal cable sections are given at the table below. Regarding the voltage drop
calculation, you may take this table as basis in your calculations. Power cables are used under earth, in cable
ducts, at inner and outer spaces, under sweet water (under salty water in case of being specially produced),
at power plants, industrial plants and switch stations. Single-core cables have single wire up to 1.5-10 mm2,
multiple wires from 10 mm2 to 300 mm2. They are isolated with non-conductor coating and there is also
outer coating around them. The ones with 2-4 cores have single wire up to 10 mm2, multiple wires in
sections greater than 10 mm2. There is a common coating over twisted cores and also a black outer coating.
