SSH HD 622 S1:1996

Kabllo fuqie që kanë tension të vlerësuar nga 3,6/6 (7,2) kV deri dhe duke përfshirë 20,8/36 (42) kV me një performancë specifike për përdorim në nën stacione

Power cables having rated voltages from 3,6/6 (7,2) kV up to and including 20,8/36 (42) kV with special fire performance for use in power stations

Scope

HO 622 applies to rigid cables for fixed installations having rated voltages U.fU (Uml from 3.6/6 (7.2) kV up to and including 20.8/36 (42) kV used in systems of voltages not exceeding the maximum r.m.s. value of the system voltage Um.
NOTE: Section H of both Part 3 and Part 4 temporarily includes cables rated 1 .9/3.3 kV. It is intended to transfer these to another publication as soon as possible.
The insulation and sheaths may be either thermoplastic or thermosetting, halogenated or halogen free. The cables are mainly intended for use in power generating plants and sub-stations. All cables have specific fire performance requirements. Cables designed to be installed within the containment area of nuclear power plants (LOCA cables). or cables specifically designed to be radiation
resistant are not included in this HO.
This Part 1 specifies the general requirements applicable to these cables; additional or deviating requirements are given in the particular sections of this HO.
Test methods are specified in EN 60811, HO 21, HO 22, HO 383, HD 405, HO 602, HO 605 and HO 606, which are referenced in the particular sections where relevant.
The particular types of cables are specified in Parts 3 and 4.
