1. Materials and Structural Parameters
Shanghai Suoqi TRVVB drag chain flat cable - the ideal choice for industrial mobile transmission 1. Brand and Product Overview Shanghai Suoqi, a well-known enterprise in the wire and cable industry, leverages deep technical expertise and a relentless pursuit of quality to create this TRVVB drag chain flat cable. This product is specially designed to meet the demanding requirements of frequent movement and bending of equipment in industrial environments, demonstrating outstanding performance and reliability.
2. Product Features High flexibility and bending resistance The conductor uses multi-strand finely twisted oxygen-free copper wire, strictly adhering to the VDE 0295 CLASS 6 standard. The single wire diameter is extremely fine and treated with a special twisting process to give the cable excellent flexibility. Laboratory tests show it can withstand over 5 million bending cycles. Under complex conditions, such as the frequent reciprocating motion of automated production chains, it can maintain structural integrity without core breakage or cracking, ensuring long-term stable power and signal transmission.
The insulation layer uses special hybrid elastomer materials (such as nitrile, automotive material, TPE, etc.), which not only provide excellent electrical insulation performance but also greatly enhance the cable's flexibility, making the insulation layer less likely to be damaged during frequent bending and effectively preventing leakage risks.
Strong 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 oil-soaked workshop environments such as machine tool processing and automotive manufacturing, facing long-term corrosion from various industrial oils such as lubricants, hydraulic oils, and cutting fluids, the cable outer sheath remains stable, without swelling or brittleness, maintaining excellent physical and electrical properties.
Cold and heat resistant: The working temperature range is wide. For fixed installations, it is -50°C to 90°C, and for mobile installations, it is -30°C to 90°C. Some specially customized models can withstand short-term temperatures up to 125°C. Whether in the high-heat steel smelting workshop, the low-temperature refrigerated cold chain warehouse, or outdoor work environments with significant seasonal temperature differences, this cable can operate stably and adapt to different temperature challenges.
Wear and tensile resistance: The outer sheath is specially reinforced with excellent wear resistance. Under repeated friction on rough mechanical surfaces, the wear rate is extremely low, and it can pass over 8 million drag chain wear tests. Additionally, the cable is cleverly designed internally, adding central tensile fibers (such as aramid yarn fiber) or high-strength galvanized soft steel wire rope (freely suspended > 80m), effectively dispersing tensile stress and withstanding tensile forces up to 10N/mm², ensuring the cable does not break or deform during frequent movement and dragging conditions, greatly extending service life.
Flame Retardant and Environmental Protection: Flame retardant rating reaches V0, complies with IEC 60332-1 fire protection standards, effectively preventing fire from spreading along cables in emergencies such as fires, ensuring the safety of personnel and equipment. No added lead, cadmium, or other harmful substances, safe and pollution-free, aligning with current green industrial development concepts.
Flexible structural design Core wire arrangement and identification: The core wires can be arranged in a straight line or in a staggered pattern according to actual needs, making it convenient to use in different installation spaces and electrical connection requirements. The core wire insulation comes in a variety of colors, allowing for colored wires; for cables with a higher number of cores, black wires with white numeric labels can also be used, making them clear and easy to distinguish. In addition, cables with more than 3 cores come with a standard yellow/green dual-color grounding wire to ensure electrical safety.
Reinforcement and shielding options: In addition to built-in tensile fibers, cables can also be equipped with shielding layers according to customer special requirements. The shielding layer is woven with tin-plated copper mesh, with a braiding density of over 85%, effectively resisting external electromagnetic interference and ensuring stable signal transmission. It is suitable for precision equipment control scenarios with extremely high electromagnetic compatibility requirements. At the same time, high-strength tensile steel wire ropes can be placed on both sides of the cable to further enhance overall tensile performance.
Sheath Customization: In addition to commonly used sheath materials such as PUR (black RAL9005, gray RAL7001, orange RAL2003) and specially modified PVC, other high-performance sheath materials can also be customized according to the customer's special requirements for weather resistance, chemical corrosion resistance, etc., to meet personalized application scenarios.
