(N)GRDGÖU 0.6/1kV Rubber Festoon Cable | TEBAOFLEX
TEBAOFLEX (N)GRDGÖU is a low-voltage rubber flexible cable for festoon systems, chain systems, cranes and material handling equipment. With flexible copper conductors, EPDM rubber insulation and a tough 5GM3 outer sheath, it is built for frequent bending in dry, damp, wet, indoor and outdoor industrial environments.
(N)GRDGÖU Rubber Festoon Cable for Moving Equipment
TEBAOFLEX (N)GRDGÖU is a heavy-duty round rubber flexible cable designed for festoon systems, cable trolleys, hoists, travelling cranes and material handling equipment. It is built for repeated bending, mobile operation and reliable power or control connection in demanding industrial environments.
This cable type is also searched as NGRDGOU, N-GRDGOU or (N)GRDGOU rubber chain cable in crane and festoon system projects.
The cable is suitable for dry, damp and wet locations, including port crane systems, overhead gantries, workshops, logistics handling lines and heavy industrial plants. For projects involving medium-voltage reeling or mining power supply, you may also compare it with our (N)TSCGEWÖU MT MV reeling cable and other Mining & Tunneling Cables.

Frequently Asked Questions
What is (N)GRDGÖU cable mainly used for?
It is mainly used as a flexible power or control cable for festoon systems, cable trolleys, cranes, hoists and material handling equipment where the cable moves frequently during operation.
How should the bending radius be selected?
The bending radius depends on cable diameter and installation method. For moving applications, drum operation or deflection pulleys, the installation should follow DIN VDE 0298-3 guidance and the final TEBAOFLEX technical datasheet.
Can TEBAOFLEX supply customized (N)GRDGÖU cable sizes?
Yes. Core number, conductor cross-section, sheath marking, packing length and project-specific requirements can be discussed. Sharing the equipment type, travel distance, speed and bending radius will help us recommend the right design.
