Installation

  • In cable channel
  • In tube
  • Underground laying with or without protection
  • In open air
  • In industry or houses

Minimum Installation & Operating Temperature

Provided the conditions explained hereunder are respected, cables can be installed and operated at low temperatures down to -20°C:

Minimum Temperature during Installation

Ideally, the cable should not be installed at an ambient temperature below 5°C.  If this is not possible, the cable must be kept in a heated room of at least 20°C for 24 hours. During installation, the temperature of the sheathing must be properly monitored. If it cools down too much (below 5°C), it must be warmed up again.

Minimum Temperature during operation

The cable can operate at a minimum ambient temperature of -20°C, provided the following conditions are met:

  • the procedure for minimum temperature during installation has been respected
  • the cable has been laid according to the rules of good practice and the bending radius has been scrupulously respected during installation
  • the cable must not move at all after installation: no repositioning and certainly no exposure to vibrations.

 

 

Maximum pulling force

The Construction Standard NBN HD 603 defines the maximum pulling force allowed by a pulling head attached to the copper conductors as follows:
Max. pulling force P = S mm² x 50 N/mm² 
where S is the sum of the nominal cross-section of all conductors.
The armouring shall not be considered in this calculation.
