Energy chain / drag chain
Supports up to 5 m/s speed and 50 m/s² acceleration in linear gantry and machine-tool drag chains.
Product
High-acceleration 0.6/1 kV (UL 1000 V) servo motor power cable engineered with IEC 60228 Class 6 copper conductors, low-capacitance polypropylene (PP) core insulation, ≥ 85 % tinned copper braid and DESINA orange RAL 2003 halogen-free PUR jacket.
Typical values for this cable type, based on DIN VDE 0250 / UL AWM Style 21223 — confirmed in the datasheet and quotation for your order.
Application fit
Designed for 4-wire (U/V/W + PE) servo and spindle motor power connections in high-speed cable carriers without holding-brake pairs.
Supports up to 5 m/s speed and 50 m/s² acceleration in linear gantry and machine-tool drag chains.
Low-loss PP dielectric (εr ≈ 2.2) and ≥ 85 % tinned copper braid contain high dv/dt IGBT switching noise.
UL 1000 V AWM Style 21223 and CSA approval allow tray routing from drive cabinet to machine entry.
Not reinforced for high-tension outdoor crane drums; use screened rubber reeling cable.
