*Impact of the changes in the construction standard of EXVB Eca

In addition to the changes made to the EXVB Eca for the purpose of the CPR with its new classification of fire reaction according to EN 50575:2014/A1:2016, the cable has undergone another major change. This change has been included in its amended construction standard NBN HD 603:2007/A1:2016, which came into force in October 2016.

This change concerns the thickness of the outer sheath: in its former version, the standard prescribed an average (nominal) thickness. These values have become the minimal thickness. This means that - on average - the outer sheath contains 10% more material.
In order to be compliant, cables produced since October 2016 must fully comply with the amended version of the construction standard, NBN HD 603:2007/A1:2016.

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.
