Energy chain / drag chain
TPE core insulation and short-pitch Class 6 bundles achieve ≥ 10 million cycles at 5 × OD and 50 m/s².
Product
SERVO FD 05855 P is a 300/500 V (UL 600 V) unscreened continuous-flex drag-chain connection cable combining IEC 60228 Class 6 copper conductors, zero-plasticiser TPE core insulation and halogen-free PUR jacket for 5 × OD bend radii down to −40 °C.
Typical values for this cable type, based on DIN VDE 0285 / UL AWM Style 20233 — confirmed in the datasheet and quotation for your order.
Application fit
Select SERVO FD 05855 P (TPE/PUR) over SERVO FD 95810 P (PVC/PUR) whenever you need a tighter 5 × OD chain bend radius, −40 °C cold-store flexing, or 100 % halogen-free construction.
TPE core insulation and short-pitch Class 6 bundles achieve ≥ 10 million cycles at 5 × OD and 50 m/s².
100 % halogen-free (IEC 60754-1/2) and UL/CSA 600 V AWM approved for machine-tool and clean plant wiring.
Performs reliably on indoor and outdoor C-rail festoons down to −40 °C.
Unscreened 300/500 V connection cable; for 0.6/1 kV main servo power use SERVO FD 80785 P or Shielded Servo Power Cable.
Use SERVO FD 80785 P (0.6/1 kV)Construction
Shown: SERVO FD 05855 P 7G0.75 unscreened TPE/PUR drag-chain cable with low-friction TPE core insulation, non-woven sliding wrap and silver-grey RAL 7001 halogen-free PUR jacket.

Technical data
Sizes
Thinner TPE core insulation yields smaller outer diameters and a 5 × OD dynamic bending radius.
