Types with or without an overall textile braid, and with or without a str

24、ain-bearing element, are included. The cables are of rated voltages U0/U 300/500 V. The cables are intended for use within high temperature zones, either: - in fixed installations with mechanical protection (cables to 4.1); or - for flexible use under low mechanical stress (cables to 4.2). The maxim

25、um 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 50525-2-83 should be read in conjunction with EN 50525-1, which specifies general requirements. 2 Normative references The
