XKDT-Y 3x1x95 Alrm / 16 CuK mm² 12/20kV

Currents are indicative and given for normal service conditions.

•  Permanent charge 24h at 100% LF =1.0
• Conductor temperature 90 ° C

For cable laid in earth in tubes

• Depth of laying in soil : 1.0 m
• Max. soil temperatureempérature : 20 °C
• Soil thermal resistivity: 1.0 °C m/W

For cables placed in the open air

• Max. air temperature : 30 °C 
• Protected from direct sunlight
• laid on consoles or cable trays

Grounding:

• at one end, in this case the induced voltage increases proportionally with the length of the
  the link.

  Attention, too high induced voltage can cause a breakdown of the outer sheath during overvoltages
  transient.

• Either at both ends, which generates circulating currents and therefore more or less acceptable losses..

Correction factor

If the terms of service differ from those set out above, allowable currents must be corrected
taking into account all the correction factors that apply to the installation and service conditions encountered.

Main factors to consider are the following:

• Variable load, factor taking into account variable load, 10h to 100% and 14h to 60% LF= 0.627

• Operating temperature
• Ambient Temperature
• Thermal soil resistivity, factor taking into account the thermal resistivity of the soil in [°C * m / W]
• Magnetic armor
