The types included are either insulated only, or insulated and braided, or insulated and sheathed. The cables are of rated voltages U0/U up to and including 300/500 V

25、. 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 180 C. NOTE HD 516 contains extensive guidance on the safe use of cables in this standard. This EN 50525-2-41 should be read

26、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. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced d
