Stranded conductor construction for drag-chain applications.
Violet PUR sheath over foil and tinned copper braid screens.
150 ± 10 ohms impedance at 3–20 MHz and 8.0 ± 0.4 mm outer diameter.
Specify the chain travel, speed, acceleration and bending arrangement with the cable selection. Coordinate support and strain relief with the moving equipment. The technical table gives a minimum laying radius of 7.5 times the overall diameter; the chain layout must also suit the operating movement.

Guided movement in drag chains or cable tracks connecting L2-BUS equipment.
PUR, with violet as the listed sheath colour.
An aluminium-lined polyester foil and an overall tinned copper braid surround the pair assembly.
The outer diameter is 8.0 ± 0.4 mm and the approximate weight is 65.0 kg/km.
The drag-chain design has a PUR sheath and its own conductor, resistance, attenuation and bending specifications.
