BENDING RADIUS WHEN INSTALLED IN L.V.
R=Dxf
R: Bending radius when installed (mm)
D: Diameter over sheath or over insulation (when it has not sheath) (mm)
f: Multiplicative factor; given the following table:
Bending radius factor LV
CALCULATION OF CURRENT CONDITION: BUILDING WIRE L.V.; 90°C
CURRENT CAPACITY VALUES AND CURRENT CALCULATION CONDITIONS BASED ON IEC 60364-5-52:2009 :
TABLE B.52.2 (METHOD A1: Two single-core cables in conduit in a thermally insulated wall).
TABLE B.52.10 (METHOD F: Two single-core cables in the air in flat formation and in contact).
Maximum conductor temperature : 90°C.
Ambient air temperature : 30°C.
The above values were corrected with a correction factor for the operating temperature of 90°C.
