Shanghai TRVVB drag chain flat cable – the ideal choice for industrial mobile transmission
1. Overview of Brands and Products
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 specifically designed to meet the demanding demands of frequent equipment movement and bending in industrial environments, demonstrating outstanding performance and reliability.
2. Product Features
High flexibility and bending resistance
The conductor uses multi-stranded finely stranded oxygen-free copper wire, strictly following 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 cycles of bending. Even under complex conditions, such as the frequent reciprocating motion of automated production chains, it can maintain structural integrity without core breaks 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 lubricants, hydraulic oils, cutting fluids, and other industrial oils, the cable outer sheath remains stable without swelling or brittleness, maintaining good physical and electrical properties.
Cold and High Temperature Resistance: Operates over a wide temperature range, with fixed installations at -50°C ~ 90°C, mobile installations at -30°C ~ 90°C, and some specially customized models can withstand short-term temperatures up to 125°C. Whether in scorching steel smelting workshops, cold chain logistics warehouses with low temperatures, or outdoor workplaces with significant seasonal temperature differences, this cable can operate stably and adapt to different temperature challenges.
Wear resistance 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 (when 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 environmentally friendly: The flame-retardant rating reaches UL94 V0, complying with the IEC 60332-1 fire protection standard. In emergencies such as fires, it effectively prevents fire from spreading along the cable, ensuring the safety of personnel and equipment. Moreover, the production process does not contain harmful substances such as lead or cadmium, ensuring safety and pollution, aligning with current green industrial development concepts.
Flexible structural design
Core wire arrangement and identification: Core wires can be arranged in a straight line or a staggered pattern according to actual needs, making it convenient for use in different installation spaces and electrical connection requirements. Core wire insulation comes in a wide variety of colors, allowing you to choose colored core wires; For cases with a large number of cores, black wires with white numeric numbers can also be used for clear and easy identification. Additionally, cables with 3 or more cores come with standard yellow/green dual-color grounding wires to ensure electrical safety.
Reinforcement and Shielding Options: In addition to the built-in tensile fibers, the cable can also include a shielding layer based on the customer's special requirements. The shielding layer uses tinned copper braided mesh with a braiding density of over 85%, effectively resisting external electromagnetic interference and ensuring stable signal transmission, suitable for control scenarios of precision equipment with very 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.
Custom sheath: In addition to common PUR (black RAL9005, gray RAL7001, orange RAL2003), and specially modified PVC, other high-performance sheath materials can also be customized according to customers' special requirements for weather resistance and chemical corrosion resistance to meet personalized application scenarios.
