Title The influence of the ageing of low-voltage power lines on the conservation of their electrical and mechanical properties
Original title Influenza dell'invecchiamento nella conservazione delle caratteristiche elettriche e meccaniche dei cavi impiegati in bassa tensione [in Italian]
Bibliographic information 2000, Vol.12, No.4, p.3-25. Illus. 21 ref.
Abstract Power lines are subject to ageing and physical stress due to heat, and to chemical and mechanical agents. The outer casing gradually loses its elasticity and becomes frail leaving the conductors exposed and raising the risk of insulation loss and direct contact, the latter being a particular safety risk. This study undertook an investigation into some of the causes of such deteriorations. Only a cable laid in a way to be mechanically protected may continue to meet electric insulation requirements for many years. If the same cable is used in equipment having moving parts it will be subjected to casing losses, expecially if no measures are adopted to allow sufficient heat dissipation.
