Flexible power cables for wind turbine applications rated up to 35 kV

1.1
This Standard specifies construction and testing requirements for thermoset insulated 
a) single-conductor or multi-conductor cable rated up to 2 kV; or 
b) single-conductor or multi-conductor metallic shielded power cables rated 5 kV to 35 kV, used in wind turbine applications where the cables are subject to frequent flexing. 

1.2
The cable constructions specified in this Standard are suitable for use at a maximum conductor temperature of 90 °C under normal operating conditions in wet or dry locations, in wind turbines. 

1.3
The values given in SI (metric) units are the standard. The values given in parentheses are for information only. 

1.4
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the Standard. 

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
