2 x 2 x 0.22mm²
The cables are used in windturbines. Among other things the CanBus cable connects the hub-box with a box in nacelle. Notice that the cable is exposed too high temperature in the gearbox and main shaft and in contact with gear and hydraulic oil
Insulation: TPE compound Colour Code: 4 Cores White-Green-Brown-Yellow Diameter: 1.40 ± 0.1 mm
Center: Fibrillated polypropilene filler Layer: 4 Cores twisted together in quad (Sequence White-Green-Brown-Yellow) + polyester tape. Can Bus pairs White+Brown , Green+Yellow
Aluminium/Polyester Tape (alu outside) braided screen of tinned copper wires (Coverage ≥ 85%) + non woven tape
