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
Shanghai Suoqi High-Flexibility Oil-Resistant Drag Chain Shielded Cable - The Outstanding Choice for Industrial Mobile Transmission I. Brand Strength and Product Overview Shanghai Suoqi Wire & Cable Co., Ltd., as a professional enterprise deeply rooted in the industry for many years, always upholds the philosophy of innovation and quality first. With advanced production equipment, exquisite manufacturing processes, and a strict quality control system, it brings a series of high-performance wire and cable products to the market, and this highly flexible oil-resistant drag chain shielded cable is an outstanding representative. It is meticulously designed to meet the complex needs of frequent equipment movement, bending, and resistance to oil contamination and electromagnetic interference in industrial environments.
2. Outstanding Product Features Exceptional high flexibility and bending resistance Conductor advantages: The conductor uses multi-strand finely twisted oxygen-free copper wire, strictly adhering to VDE 0295 CLASS 6 standard. The single wire diameter is extremely fine, and after special twisting processing, the cable is endowed with extraordinary flexibility. In laboratory simulation tests, it can withstand up to 8 million cycles of bending. Even under complex industrial conditions, such as frequent reciprocating motion in automated production line drag chain systems, it maintains structural integrity without issues such as core breakage or cracking, ensuring long-term stable transmission of power and signals.
Insulation Assistance: The insulation layer is made of a special blended elastomer material, which not only has excellent electrical insulation performance but also further enhances the flexibility of the cable. During frequent bending, the insulation layer can effectively protect the conductor, greatly reducing the risk of leakage and ensuring the safety of equipment and personnel.
Excellent Oil Resistance: The outer sheath is made of high-quality polyurethane (PUR) or specially modified PVC material, successfully passing the ISO 1817 oil resistance test. In machine tool workshops, there is an abundance of lubricants and cutting fluids; in automobile manufacturing plants, various oils are pervasive. In these environments, the cable outer sheath can effectively resist long-term corrosion from various industrial oils, without swelling, embrittlement, or other phenomena, consistently maintaining good physical and electrical properties, ensuring the cable's reliable operation in oily environments.
Powerful Shielding Performance The cable is equipped with an anti-oxidation tin-plated copper braided shielding layer, with a braiding density of ≥85%. This high-density shielding layer can efficiently block various external electromagnetic interference signals. Whether in environments with strong magnetic fields generated by large motors or in automation control areas with complex signals, it can ensure stable and accurate signal transmission inside the cable, with no errors and no delays, effectively preventing device malfunctions or operational abnormalities caused by signal interference. It is especially suitable for precision equipment and control systems with extremely high electromagnetic compatibility requirements.
Wide environmental adaptability: Cold and high temperature resistance: The operating temperature range is extremely broad. When fixed installation, it can stably run within a temperature range of -50°C ~ 90°C, and can also adapt to -30°C ~ 90°C during mobile installation. 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 handle it with ease and operate normally, fully demonstrating its powerful temperature adaptability.
Wear-Resistant and Tensile-Resistant: The outer sheath is reinforced through a special process, making its wear resistance extremely outstanding. When repeatedly rubbed against rough mechanical surfaces, the wear rate is very low, successfully passing drag chain abrasion tests over 8 million cycles. Meanwhile, the cable's internal design is ingenious, incorporating central tensile-resistant fibers (such as aramid yarn fibers) or high-strength galvanized flexible steel wire ropes (when freely suspended >80m), which can effectively disperse tensile stress and withstand tension up to 10 N/mm². Even under harsh conditions of frequent movement and heavy dragging, the cable will not break or deform, significantly extending its service life and reducing equipment maintenance costs and downtime.
Flame Retardant and Environmental Protection: Flame retardant rating reaches V0, strictly complying with IEC 60332-1 fire protection standards. In emergencies such as fires, the cable can quickly and automatically block the spread of fire, buying valuable time for evacuation and firefighting, and effectively ensuring the safety of personnel and equipment. Moreover, No harmful substances such as lead or cadmium are added, ensuring safety and pollution, in line with current trends and requirements of green industry development.
Flexible structural design Core wire arrangement and identification: Core wires can be flexibly arranged in a straight line or plum blossom pattern according to actual usage needs to suit different installation spaces and electrical connection requirements. Core wire insulation comes in a wide variety of colors, allowing for the choice of colored core wires; For cables with a large number of cores, black wire bodies with white numeric numbers are used, making them clear and easy to distinguish, making installation and maintenance convenient. Additionally, cables with 3 or more cores come with standard yellow/green dual-color grounding wires, further ensuring electrical safety.
Reinforced and Shielded Customization: In addition to built-in tensile fibers, cables can also be customized with different types of shielding layers according to specific customer requirements, such as a combination of aluminum foil shielding and tinned copper braided shielding, further enhancing the shielding effect. At the same time, high-strength tensile steel wires can be placed on both sides of the cable to further improve overall tensile performance, meeting customers' extreme requirements for cable performance under special working conditions.
