The cables are of rated voltages U0/U up to and including 450/750 V. NOTE 1 Cables rated 450/750 V may be used at 600/1 000 V when this
24、 cable is used in fixed installations with mechanical protection, within switchgear and control gear. See HD 516. The cables are intended for use in fixed installations within high temperature zones. The maximum conductor operating temperature for each of the cables in this standard is 110 C. NOTE 2
25、 HD 516 contains extensive guidance on the safe use of cables in this standard. This EN 50525-2-42 should be read in conjunction with EN 50525-1, which specifies general requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.
