Foreword
This European Standard was prepared by TF “Covered Overhead Line Conductors (COHL)” of the
Technical Committee CENELEC TC 20, Electric cables.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50397-1 on
2006-07-01.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-07-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-07-01
This European Standard consists of two parts:
– Part 1 "Covered conductors"; and
– Part 2 "Accessories for covered conductors: Tests and acceptance criteria".
This standard covers the construction, performance and test requirements for covered conductors for
overhead lines having a nominal voltage U above 1 kV a.c. up to and including 36 kV a.c., and for the
related accessories.
