Numerical Control Processing Tensile Design of Reel Cables

In harsh working conditions such as mining operations and port loading and unloading, ordinary winding cables frequently experience problems such as sheath cracking, conductor breakage, internal twisting, and bulging, leading to equipment downtime and high replacement costs. Shanghai Suoqi drum cables are specifically designed for such conditions, with conductors made of multi-stranded ultra-fine oxygen-free bare copper wires (VDE 0295 CLASS 5/6 standard). The sheath is made of imported polyurethane (PUR) composite material, with a double-layer sheath reinforced with a tensile braided layer to prevent twisting and bulging. The cable features shielding and waterproof characteristics and is widely used in machinery, loaders, and reels. Shanghai Suoqi Cable is sold directly from the source factory, customizable with multiple cores and specifications as needed, with ample stock available for nationwide delivery.

Product Features

Operation Status Monitoring: Devices such as temperature sensors and stress sensors can be used to monitor the cable's operating status in real time. If abnormal temperatures or excessive bending are detected, on-site inspection should be carried out promptly to check for localized overheating, uneven stress, and other conditions.

Fault handling measures: Circuit break: After confirming that the wire is interrupted from start to end, if there is a local fracture, the insulation at the broken point can be removed, connected with crimp terminals, and the outer layer sealed with heat shrink tubing; If the fracture is severe, replace the conductor or the entire cable.

Short circuit fault: Confirm the location of the short circuit. If the damage is caused by insulation damage, repair the damaged insulation. If the damaged area is large or difficult to repair, relay the cable or replace the damaged section.

Poor contact fault: Clean the oil and oxide layer on the wire contact surface, apply waterproof conductive grease, and then re-tighten the wire connection points. If necessary, a metal waterproof junction box can be added.

Preventive maintenance measures: Standardized installation and operation: Ensure the cable is laid flat and winded evenly during installation to avoid mechanical damage caused by localized stress. Operators should handle the cable gently during use and avoid severe pulling and compression.

Frequently Asked Questions

Why is a Kevlar tensile layer used in reel cables?

During winding and unwinding, the cable is subjected to continuous axial tension. Aramid/Kevlar tensile fibers can share the tension, preventing the conductor from being elongated or deformed and ensuring stable electrical performance.

What is the minimum bending radius of a reel cable?

Generally, it should be no less than 6 times (6D) the outer diameter of the cable. For reel winding and unwinding conditions, it is recommended to check according to the diameter of the equipment drum to avoid long-term bending that could cause the sheath to crack.
