Flexible Single Core EPR/PUR Medium Voltage Reeling Cable 1.8/3 (3.6) kV to 12/20 (24) kV High-Flex Industrial Cable for Reel and Festoon Applications
Product Overview
This flexible single-core medium voltage cable is engineered for demanding mobile power supply systems such as cable reels, festoon systems, and continuous flexing industrial machinery. Designed for high mechanical stress environments, it provides excellent electrical performance, mechanical durability, and resistance to harsh operating conditions including oil, UV radiation, ozone, and moisture.
The cable construction combines high-flex copper conductors, EPR insulation, dual semi-conductive layers, and a robust PUR outer sheath to ensure long service life in both indoor and outdoor applications.

Cable reels (motor-driven and manual systems)
Festoon systems in cranes and hoists
Mining and heavy industrial mobile machinery
Port equipment and container handling systems
Industrial automation with continuous movement
Outdoor and harsh environmental installations
