BILINGUAL

CZ.1 New overhead line

The new overhead line is considered a brand new electric
overhead line with nominal voltage exceeding 1 kV AC, between the
points A and B.

The new branch line of the existing overhead line shall be
considered a new overhead line except for a junction support for
which the specific requirements shall be defined in the Project
Specification.

The extent of application of this standard in respect of
reconstruction, relaying and extension of existing overhead lines
shall be determined in the Project Specification. Simultaneously,
the Project Specification shall determine, which of the previous
national standards shall be used and to what extent they shall be
used for the project in question.

Field of application 

CZ.1 Field of application

The requirements of this standard shall be adopted, where
applicable (e.g. requirements on loads, external clearances, etc.),
for telecommunication cables as well.

In case of overhead line under the design stage, parties
concerned shall agree the extent of the application of this
standard.

Overhead line under construction may be completed according to
standards valid during the design stage of the line. The parties
concerned shall agree any possible application of certain clauses
of this standard.

CZ.2 Installation of telecommunication equipment on
supports

Provisions of this standard also apply to the telecommunication
equipment and devices (aerials, dish antennas, etc.) which are
installed on individual supports of overhead power lines,
especially in terms of wind and ice loads on such installed
equipment. Design and installation has to respect requirements of
the utility operating the line in question. The design of such
telecommunication equipment has to incorporate such technical
solutions and such precautions, which shall allow safe access and
maintenance of both a power line and telecommunication equipment,
and which shall provide protection of persons performing repairs or
maintenance of the power line and/or telecommunication equipment
against electric shock and protection of telecommunication
equipment and attached installations against the influence of the
power line (short-circuits, switching and lightning overvoltages
etc.).
