This cable has been custom designed specifically for Irrigation Installations. It consist of two cores of copper wire with conductors with a round profile area each of 2.5 sq.mm.
The Cable has three ply protection.
A tough outer polyethylene 'shell' (MDPE).
PVC Sheath around the copper wire, one coloured red and the other blue.
Insulation material between the sheaths and the shell. This material is XLPE or PEX and is made from high density polyethylene (HDPE). A 'cross-linking process is carried out during process.
The cross linking provides three key improvements to the material by:
Enhanced high temperature tolerance.
Reducing moisture permeability
Enhanced dielectric properties, which is is important for medium voltage -50kV AC.
The cable's outer shell is coloured bright orange to enhance visability.
