What is BS EN 50397 ‑ 1 -  Covered conductors for overhead lines   about?

BS EN 50397-1:2020 Covered conductors for overhead lines and the related accessories for rated voltages above 1 kV AC and not exceeding 36 kV AC is the UK implementation of EN 50397‑1:2020 . It supersedes BS EN 50397‑1:2006 , which is withdrawn. BS EN 50397-1 is part of a three parts series consisting of:

BS EN 50397-1:2020 Covered conductors

BS EN 50397-2:2022 Accessories for covered conductors: Tests and acceptance criteria ; and BS EN 50397-3:2022 Guide to use

The BS EN 50397 series covers the construction, performance, and test requirements for covered conductors for overhead lines having a nominal voltage U above 1 kV AC up to and including 36 kV AC, and for the related accessories. Covered conductors consist of a conductor surrounded by a covering made of insulating material as protection against accidental contacts with other covered conductors and with grounded parts such as tree branches, etc. In comparison with insulated conductors, this covering has reduced properties but is able to withstand the phase-to-earth voltage temporarily. Since covered conductors are unscreened, they are not touch-proof, i.e. they should be treated as bare conductors with respect to electric shock. These documents do not cover aspects re...
