Overview
EN 50397-1:2020 (CLC) specifies requirements for covered conductors for overhead lines with rated voltages above 1 kV AC and not exceeding 36 kV AC. Part 1 of the EN 50397 series covers the construction, marking and testing of the covered conductor itself (with or without integrated longitudinal watertightness and/or a semi‑conductive conductor screen). The standard clarifies performance expectations for coverings that provide protection against accidental contacts while acknowledging that covered conductors remain unscreened and are not touch‑proof.

The EN 50397 series consists of three parts:

— Part 2, “Accessories for covered conductors: Tests and acceptance criteria”; and
— Part 3, “Guide to use”
Introduction
The 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.
This document does not cover aspects related to the installation of overhead lines such as determination
of clearances, spans, sags, etc.
1 Scope
This document contains the requirements for covered conductors with or without integrated longitudinal
water tightness and/or semi-conductive conductor screen for applications in overhead lines with rated
voltages U above 1 kV a.c. and not exceeding 36 kV a.c.
