Our primary cable is constructed to FAA AC 150/5345-7F -type B standards.
The cable construction is as follows
|
Conductor |
6mm2 tinned copper, 7 Strand |
|
Voltage Rating |
5kV |
|
Insulation |
Ethylene propylene rubber (EPR) |
|
Sheath |
High density polyethylene - termite resistant |
Our standard cable is EPR insulated due to its superior to water ingress. Water ingress is the biggest risk to enduring acceptable insulation resistance values in airport lighting systems.
Airport lighting primary circuits can have more than 200 plug and socket connections each being a potential point of entry for water ingress which can degrade the cable insulation. EPR is more tolerant of exposure to moisture than some other insulation types commonly used including XLPE.
