Special Applications

 

Is it OK to use EPR/PCP Mine Trailing Cables in submersible applications?

Olex does not view our PCP sheathed cable as being a long term solution for submersible applications. The PCP contains Magnesium Oxide (as a curing agent) which will absorb water.

A better solution would be to utilise a CPE sheath, as used on our Flexolex® range, which does not contain Magnesium Oxide. It has also been tested at elevated water pressures and has been found to be suitable for submersible applications such as submersible pump motor connections.

Both cables contain cores which are insulated with EPR. The insulation itself gives good protection from water penetration although it would be preferable for the sheath to do so also. Therefore, for this application, CPE is the preferred sheathing material rather than PCP.
