Type 245.3
Type 245.3
Semiconductive screened and flexible cable for use as longwall shearer cable. The flexible conductor allows for much reduced bending radii so this cable will tolerate bending in the cable chain (often called 'Bretby'). Cable has 3 central pilots for earth continuity monitoring and for control circuits.
