IEC 60092-354-2020 pdf free download – Electrical installations in ships – Part 354: Single- and three-core power cables with extruded solid insulation for rated voltages 6 kV (U m = 7,2 kV) up to 30 kV (U m = 36 kV).
This part of lEC 60092 is applicable to shipboard and offshore power cables with extrudedsolid insulation, conductor and core screening, having a voltage rating of one of the following:3,6/6 (7,2) kV,6/10 (12) kV,8,7/15 (17,5) kV,12/20 (24) kV,18/30 (36) kv.
NOTE 1 Subclause 4.1 gives more details.
The cables are intended for fixed installations.
The various types of power cables are given in 5.1.The constructional requirements and testmethods are aligned with those indicated in IEC 60092-350,unless otherwise specified in thisdocument.
The object of this document is:
– to standardize cables whose safety and reliability is ensured when they are installed in
accordance with the requirements of lEC 60092-352 or lEC 61892-4;
to lay down standard manufacturing requirements and characteristics of such cablesdirectly or indirectly bearing on safety;
– to specify test methods for checking conformity with those requirements.NOTE 2 Only radial field cables are covered.

4General requirements
4.1 Rated voltage
The standard method of designating the rated voltages of cables covered by this documentshall take the form
where
U 0 is the rated power-frequency voltage between phase conductor and earth or metallic
screen, for which the cable is designed;
U is the rated power-frequency voltage between phase conductors for which the cable is
designed;
U m is the maximum value of the “highest system voltage” for which the equipment
(including cable) may be used (see IEC 60038).
All voltages are given as RMS values.
The standard rated voltages U 0 /U (U m ) of the cables considered in this document are:
U 0 /U (U m ) = 3,6/6 (7,2) − 6/1 0 (1 2) − 8,7/1 5 (1 7,5) − 1 2/20 (24) − 1 8/30 (36) kV
4.2 Markings
4.2.1 Indication of origin and voltage identification
Cables shall comply with 4.1 .3 of IEC 60092-350:201 9 with respect to:
b) indication of origin;
c) rated voltage and cable construction (number of cores and cross-sectional area of the construction);
d) continuity of marking;
e) durability/legibility.IEC 60092-354 pdf download
