Cranes and overhead traveling equipment are subjected to long-term reciprocating movement and suspended 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 core wires are flexibly bundled and woven to prevent twisting, the outer sheath is made of high-strength composite elastomer, and built-in Kevlar tensile elements are included, making them suitable for the frequent suspension and movement conditions of gantry cranes. In actual applications, the product has gained recognition from customers in the machinery, port, and mining sectors for its oil resistance, corrosion resistance, and waterproof performance. Customization according to drawings and direct shipment from stock are supported. For details, call 13311756197.

Product Features

(2) Structural Design Conductor: Multi-strand finely stranded oxygen-free bare copper wire, compliant with VDE0295 CLASS 5 or 6 standards, ensuring low resistance and high flexibility.

Mechanical properties

The conductor is made of multi-strand finely twisted oxygen-free bare copper wire, meeting VDE0295 CLASS 5 or 6 standards, ensuring the cable is flexible, bend-resistant, and torsion-resistant; the cable core can be arranged in either a single-row or trefoil pattern according to requirements, and can have built-in metal or non-metal tensile and bend-resistant conductors, with a service life 3-6 times that of traditional ordinary cables.

Electrical performance

Rated voltage U0/U 450/750V~0.6/1KV, test voltage 3000V, with excellent electrical insulation and anti-interference capability.

Temperature adaptability

The operating temperature range is -20°C to 80°C, with special models extending to -30°C to 90°C, maintaining stable performance even in extreme temperature environments.

Insulation

The special hybrid elastomer material is soft and insulating, providing reliable electrical insulation performance.

Structure

The cable cores are arranged in a single line or in a staggered pattern to meet different hanging length and moving speed requirements.

Reinforcement

Depending on the usage scenario, you can choose galvanized soft steel wire rope (when freely suspended over 80 meters) or fiber aramid yarn to enhance the tensile performance of the cable.

Sheath

Special blended elastomer neoprene material sheath, color options available in black (RAL9005) or gray (RAL7001); additionally, a PUR polyurethane reinforced material sheath is also available, further enhancing wear resistance and chemical resistance.

Customized services

As a source manufacturer of special flexible cables, Shanghai cable companies can customize flat cables according to drawings or working conditions, with stable delivery times and controllable quality. Welcome to call 13311756197 for solutions and quotations.

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.

What temperature range is flat cable suitable for?

Conventional elastomer sheaths are suitable for temperatures from -20°C to 80°C, while special low-temperature formulations can be used to reduce temperatures down to -40°C, with specific selection based on operating conditions.
