Shanghai Suoqi Cable Co., Ltd. is deeply engaged in the field of special flexible cables. The following provides a professional interpretation of drag chain cables from three dimensions: material structure, performance advantages, and application scenarios.
1. Materials and Structural Parameters
Flexible Drag Chain Control Cable TRVVP Drag Chain Shielded Cable - Shanghai Suoqi 1. Product Introduction This flexible drag chain control cable (TRVVP drag chain shielded cable) is meticulously crafted by Shanghai Suoqi Wire and Cable Co., Ltd. As a comprehensive modern enterprise integrating research and development, production, sales, and service, Shanghai Suoqi has rich technical experience in the wire and cable field, with strong R&D capabilities and a scientific management system, ensuring excellent product quality.
2. Product Features High Flexibility: The conductor is made of ultra-fine, precision-stranded oxygen-free copper wire, conforming to VED0295 CLASS 6 standards. Each strand has an extremely small diameter and, through a special stranding process, the cable achieves high flexibility. It can bend frequently in drag chain systems, has a small bending radius, can adapt to complex installation and usage environments, and effectively reduces installation difficulty and space constraints.
Excellent shielding performance: Uses 85% tinned copper braided shielding (some products have dual-layer shielding, such as aluminum foil and tinned copper braid, with a shielding coverage of ≥90%), effectively shielding against various external electromagnetic signal interferences, complying with anti-interference standards such as EN 50217, ensuring stable signal transmission. Suitable for precision equipment and control systems with high electromagnetic compatibility requirements, such as automated production lines, CNC machine tools, and robot control, ensuring data transmission with zero errors and zero delays.
Resistant to various harsh environments: The outer cover uses imported high-end PUR material, passed ISO 1817 oil resistance tests, and is highly resistant to grease, coolant, etc. It is not easily eroded, suitable for machinery processing, food processing, and other oil-contaminated work scenarios.
Cold and heat resistant: Wide working temperature range, -50℃ ~ 90℃ for fixed installation, -30℃ ~ 90℃ for mobile installation. Some special models can withstand short-term temperatures up to 125℃, adaptable to different temperature environments such as high-temperature workshops, cold storage, and outdoor settings, suitable for industries like steel smelting and cold chain logistics.
Wear-resistant and tensile-resistant: Through special processing, the outer sheath of the cable has excellent wear resistance, passing over 8 million drag chain tests, with a sheath tear strength ≥15 N/mm². At the same time, the internal structure is reasonably designed, with central tensile fibers added to enhance overall tensile performance. It is not easily damaged during frequent movement and dragging, extending its service life.
The flame retardant rating reaches V0, meeting the IEC 60332-1 fire protection standard, and is halogen-free and safe. In the event of a fire or other emergencies, it can effectively prevent the spread of flames, ensuring the safety of personnel and equipment. It is suitable for places with high fire safety requirements.
Long lifespan: Thanks to high-quality materials and advanced manufacturing processes, the cable has a long dynamic bending life in drag chain systems, with some specifications reaching over 10 million cycles (Test standard: DIN VDE 0295), reducing replacement frequency, lowering maintenance costs, and improving equipment operation efficiency.
Flexible selection: Supports multiple core counts (4 ~ 36 cores), and custom shielding options (single/double layer) and jacket materials (PUR black/gray, TPE orange, etc.) based on customer requirements, meeting the diverse needs of different equipment and usage scenarios.
3. Product Parameters Rated Voltage: <0.5mm² is 300/300V; ≥0.5mm² is 300/500V.
2. Performance Technical Indicators
This series of products undergoes strict process control and quality inspection, ensuring stable and reliable performance that meets the needs of various industrial application scenarios.
3. Application Scenarios
Drag chain cables are widely used in fields such as industrial automation, hoisting and transportation, and ports and docks.
