Marine Flex Yzp
Marine Flex Yzp
These extra flexible low voltage cables for fixed installation ensure easy installation, also in tight spaces
and for bigger conductor sizes. The sheath material has excellent abrasion resistance properties and can
be stripped easily with the ripcord. Halogen-free and low-smoke, flame-retardant in fire conditions.
Different sheath colours available on request.

Current Rating for General Installations Current carrying capacities in continuous service
The current ratings are applicable for d.c. and at maximum rated conductor temperature of 90 °C in A,
a.c. with a nominal frequency of 50 Hz or 60 Hz at 45° C ambient air temperature
and an ambient air temperature of 45° C. For Current Rating (A)
higher frequencies, the current rating shall be
calculated with an appropriate method (e.g. IEC Cross
Number of cores loaded
60287). For other ambient air temperatures the Section
correction factors have to be applied. These (mm2)
ratings are applicable, without correction factors, 1 2 3&4

than six cables operating simultaneously at their 6 52 44 36
full rated capacity are laid close together without 10 72 61 50
free air circulating around them. In this case a 16 96 82 67
correction factor of 0.85 should be applied. The 25 127 108 89
