Cranes and overhead traveling equipment are constantly subjected to reciprocating movement and suspension bending. Ordinary round cables take up space, are not wear-resistant, and are prone to issues such as outer sheath wear and cracking, and breakage of the core wires. To address this pain point, Shanghai Suoqi has optimized its flat cables in both materials and processes: the conductors are finely stranded ultra-fine oxygen-free copper wires, and the sheath uses a special elastomeric nitrile composite material. The flat design saves installation space, is bend-resistant, tensile-resistant, and tangle-free. In practical applications, the product has been recognized by customers in machinery, ports, and crane sectors for its tensile strength, oil resistance, and shielding performance. Customization based on drawings and direct delivery from stock are supported. For details, contact 13311756197.

Product Features

Good anti-interference capability: Cables with shielding layers have a tin-plated copper braiding density of ≥85% and aluminum foil wrapping density of ≥99%, effectively suppressing electromagnetic interference and ensuring the stability and accuracy of signal transmission.

Good environmental adaptability: It has a wide temperature range, generally usable in environments from -45℃ to 120℃, and features IP67 waterproofing, oil resistance, and UV radiation resistance, making it suitable for various harsh working conditions.

Technical parameters: The rated AC voltage is generally Uo/U = 450V/750V. The power line cores can withstand a 50Hz, 2500V voltage test for 5 minutes, and the control line cores can withstand a 50Hz, 1500V AC voltage test.

Scope of Application: Widely used in large mobile equipment such as cranes, electric hoists, gantry cranes, and portal cranes. It can be installed in cable reels or festoon systems, and is also suitable for industries such as metallurgy, electric power, shipping, and ports. It is used for power transmission lines as well as control, lighting, and communication lines of AC rated voltage 0.6/1KV and below for mobile electrical equipment.

Frequently Asked Questions

Which is more bending resistant, flat cable or round cable?

Flat cables are especially advantageous in lifting scenarios with frequent movement and limited space; their flat structure is evenly stressed and not easily twisted, making them suitable for reciprocating movements such as cranes and overhead cranes.

Why are flat cables arranged in a plum blossom/straight line?

This type of cable core arrangement can optimize space and reduce thickness within a limited cross-section, while ensuring consistent force on each core, enhancing overall flexibility.
