ANNEX A

Guide to use

Specified cables according to HD 604 Part 5, Section К may be laid indoors or in air in buildings or sites where the effects of a fire (especially in crowded places, places with high value devices or security equipment) have to be reduced to a minimum.

Current-carrying capacity
1. Conductor temperature

The highest permissible temperature at the conductor is 90°C. The maximum temperature for short-circuit conditions is 170°C for thermoplastic polymer compounds and 250°C for crosslinked polymer compounds.

Current carrying capacity for long time operation

The values given in Table A.1 for current carrying capacity are based on the assumption of 30°C ambient air temperature and free circulation of air.

Conversion factors for grouping in air

For grouping of cables and cable systems the conversion factors, given in table A.2 or A.3 are valid.

Conversion factor for deviating air temperatures

For deviating ambient air temperatures the following factors are valid:

Ambient temperature °С	10	15	20	25	30	35	40	45	50
Conversion factor	1.15	1.12	1.08	1.04	1.0	0.96	0.91	0.87	0.82

3. Permissible short-circuit temperature and rated short-time current densities

The values for permissible short-circuit temperature and rated short-time current densities are given in Table A.4 and A.5
