Shanghai Suoqi TRVV flexible drag chain cable – the core guarantee for industrial mobile transmission
1. Brand and Product Introduction
Shanghai Suoqi Wire & Cable Co., Ltd. has been deeply involved in the wire and cable field for many years, becoming an industry leader thanks to cutting-edge technology, advanced equipment, and strict quality control. As a star product, TRVV flexible drag chain cable is specially designed for complex conditions where equipment frequently moves and bends in industrial environments, meeting the needs of power transmission and signal transmission. It is an ideal choice for industrial automation, intelligent manufacturing, and other scenarios.
2. Product Features
Outstanding high flexibility and bending resistance
Conductor Manufacturing: The conductor uses multi-strand finely twisted oxygen-free copper wire, strictly compliant with VDE 0295 CLASS 6 standard, with an extremely fine single wire diameter. A special twisting process gives the cable high flexibility. Laboratory tests show it can withstand over 8 million bending cycles, maintaining structural integrity during the frequent reciprocating motion of automated production line drag chains, with no core breaks or cracks, ensuring long-term stable power and signal transmission.
Insulation empowerment: The insulation layer uses special hybrid elastomer materials such as nitrile, automotive material, and TPE. This not only provides excellent electrical insulation performance but also greatly enhances cable flexibility. During frequent bending, the insulation layer effectively protects conductors, reduces leakage risks, and ensures the safety of equipment and personnel.
Excellent environmental adaptability
Oil Resistance: The outer sheath is made of high-quality polyurethane (PUR) or specially modified PVC, and has passed ISO 1817 oil resistance testing. In lubricants and cutting fluids in machine tool machining workshops, as well as in various oil-stained environments in automotive manufacturing plants, the outer sheath can withstand long-term erosion, remain non-swollen and non-brittle, maintain good physical and electrical properties, and ensure stable operation of cables in oil-contaminated environments.
Wide temperature adaptation: Wide operating temperature range, -50°C ~ 90°C for fixed installation, -30°C ~ 90°C for mobile installation, and some specially customized models can withstand short-term temperatures up to 125°C. Whether in high-temperature steel smelting workshops, cold chain logistics warehouses, or in outdoor environments with complex temperature differences, the cable can operate normally.
Wear-resistant and tensile-resistant: The outer sheath is reinforced through a special process, providing excellent wear resistance. When repeatedly rubbed against rough mechanical surfaces, the wear rate is low, and it can pass drag chain wear tests over 8 million times. The internal design is ingenious, incorporating central tensile fibers (such as aramid yarn fibers) or high-strength galvanized flexible steel wire ropes (when freely suspended >80m), capable of withstanding tensile forces up to 10N/mm². Under frequent movement and dragging, the cable does not break or deform, significantly extending its service life.
Flame retardant and environmentally friendly: The flame retardant rating reaches UL94 V0 and complies with the IEC 60332-1 fire protection standard. In the event of a fire, it can quickly prevent the spread of flames, allowing time for evacuation and firefighting, ensuring safety. In production, no harmful substances such as lead or cadmium are added, making it green and non-polluting.
Flexible structural design
Core wire layout and identification: Core wires can be arranged in a straight line or plum blossom pattern according to actual needs, adapting to different installation spaces and electrical connection requirements. Core wire insulation comes in various colors: < 0.5mm², available in brown, black, blue, red, purple, white, orange, etc.; ≥ 0.5mm², black wire with white numeric numbering is used for clear and easy identification. Cables with 3 cores or more come with standard yellow/green dual-color grounding wires to ensure electrical safety.
Reinforcement and customization: In addition to built-in tensile fibers, a shielding layer can be added according to customer requirements (such as tinned copper mesh weaving, with a weaving density of ≥85%) to resist electromagnetic interference and meet the control needs of precision equipment. High-strength tensile steel wire ropes can also be placed on both sides of the cable to further enhance tensile performance.
Sheath customization: In addition to the commonly used sheath materials such as PUR (black RAL9005, gray RAL7001, orange RAL2003) and special modified PVC, high-performance sheath materials can be customized according to customers' special requirements for weather resistance, chemical corrosion resistance, etc., to meet personalized scenarios.

4. Application Scenarios
Industrial Automation Production Line: Connects moving parts of automated equipment, such as AGV carts and material handling machinery drag chain systems, ensuring stable power and signal transmission, improving production efficiency and product quality.
CNC machine tools: provide power and signals for machine tool control systems and servo motors, meeting the needs of frequent and rapid motion during high-speed, high-precision machining, ensuring machining accuracy and efficiency.
Logistics and warehousing equipment: Used for automatic sorting equipment, stackers, conveyor drag chain systems, adapting to fast and frequent equipment movements, ensuring smooth logistics operations, and enhancing automation levels and operational efficiency.
Cranes and overhead cranes: As drag chain cables, they withstand the tension and bending during equipment lifting and translation, providing stable power for equipment operation and ensuring safe and reliable lifting operations.
Other frequently bending scenarios: such as glass machinery, woodworking machinery, and packaging machinery drag chain systems, which stably complete power and signal transmission tasks during equipment operation.
Selection Tips
For the power supply needs of woodworking machinery injection molding machines, it is recommended to choose waterproof and flame-retardant products, with specifications ranging from 0.2 to 240mm². Shanghai cable companies can provide selection suggestions and samples based on equipment travel, dragging speed, and installation space.
