What parameters should be prioritized when selecting a reel cable? What are the requirements for the minimum bending radius? How should the selection be made?

Answer：

The key parameters are primarily evaluated across five dimensions:

1. Voltage level: 0.6/1 kV, 6/10 kV, etc., matching the equipment's power supply system.

2. Conductor cross-section: Select based on the equipment's current load to prevent overheating due to overload.

3. Core configuration: Power core + Control core + Shielding/fiber optic core, customizable as needed.

4. Mechanical properties: bending radius, winding turns, tensile strength, compatible drum diameter, and winding/unwinding speed.

5.Environmental requirements: Temperature range, oil resistance/acid/alkali resistance/UV protection rating, tailored to on-site operating conditions.

Minimum bending radius requirement for reel cables:

The cable outer diameter should generally be 6 to 10 times the required value, with specific dimensions determined by the reel diameter. If the reel diameter is too small, it may cause conductor fatigue fracture and sheath cracking, significantly reducing the cable's service life.

Cable reels are categorized into flat cable reels and round cable reels:

For scenarios where the reel has limited space, is prone to torsion, and requires neatly arranged cables (For normal driving, elevators), flat-reel cables are recommended.

For high-speed, long-stroke applications requiring higher tensile strength (such as large port cranes and mining equipment), round drum cables are recommended.
