Shanghai Suoqi EKM Polyurethane Drag Chain Cable - Excellent Transmission Solution in Harsh Industrial Environments
1. Brand and Product Overview
Shanghai Suoqi Wire & Cable Co., Ltd., as a dedicated player in the wire and cable industry, has established an outstanding reputation in the field through its advanced technological R&D capabilities, precise production equipment, and strict quality control system. Its EKM polyurethane drag chain cable is meticulously designed to meet the demanding requirements of industrial environments, including frequent equipment movement, complex bending, and harsh operating conditions, making it a key component in ensuring the stable operation of industrial automation systems.
2. Product Structure Analysis
Conductor: Uses multi-strand ultra-fine precision-stranded oxygen-free copper wire, strictly following the VDE0295 CLASS 6 standard. The extremely fine single wire diameter, combined with a special stranding process, gives the cable high flexibility, effectively reduces resistance, and ensures efficient power and signal transmission. Even during long-term, high-frequency bending, it can maintain good conductivity and reduce energy loss.
Insulation: Special blended PVC insulation material is selected. This material has excellent electrical insulation properties, effectively isolating current and preventing leakage. At the same time, while maintaining good insulation characteristics, it enhances the flexibility and mechanical performance of the cable, providing reliable assurance for the stable operation of the cable under complex conditions.
Core identification: The wire core identification design is thoughtful. When the cross-sectional area of the core is less than or equal to 0.5mm², it uses a variety of colors such as brown, black, blue, purple, pink, and orange for differentiation. When the core cross-sectional area is greater than or equal to 0.5mm², a black wire body with clear white numeric numbers is used for easy identification. Additionally, cables with three or more cores come with standard yellow/green dual-color grounding wires, greatly enhancing electrical safety and facilitating installation and later maintenance.
Sheath: The outer sheath uses high-quality imported polyurethane (PUR) material. Polyurethane material has outstanding overall performance, with wear resistance far exceeding ordinary cable sheath materials. During frequent friction with mechanical components, it effectively resists wear and significantly extends cable service life. At the same time, PUR sheaths have excellent oil resistance, maintaining stability in various industrial oil contamination environments such as lubricants and cutting fluids, without swelling or brittleness; Their cold resistance is also outstanding, maintaining good flexibility and mechanical strength even in low-temperature environments; They also have good weather resistance, able to withstand UV rays, ozone, and other environmental factors, making them suitable for various complex indoor and outdoor environments.
3. Product Performance Advantages
High Flexibility and Bend Resistance: Based on a unique conductor and insulation design, the cable exhibits extremely high flexibility. In tests simulating actual industrial applications, it can easily withstand over 5 million bending cycles, far exceeding the industry average. Whether in high-speed operating equipment on automated production lines or in areas with frequent and complex movements such as robot joints, it can adapt flexibly, always maintaining structural integrity, without conductor breakage or cracking, ensuring continuous and stable power and signal transmission.
Outstanding Wear Resistance: The PUR material of the outer sheath is treated with a special process, further enhancing its wear resistance. Under conditions of repeated friction against rough mechanical surfaces, the wear rate is extremely low, and it can pass chain drag wear tests of over 8 million cycles. For example, in application scenarios prone to high-intensity friction, such as woodworking machinery and stone cutting equipment, EKM polyurethane drag chain cables can operate stably due to their excellent wear resistance, reducing failures and replacement frequency caused by wear, and lowering equipment maintenance costs.
Strong oil resistance, cold resistance, and weather resistance
Oil resistance: Passed ISO 1817 oil resistance tests, offering strong resistance to various industrial oil stains. In environments such as machine tool workshops and automobile manufacturing plants filled with large amounts of lubricating oil, hydraulic oil, and cutting fluids, cable outer sheaths can effectively resist long-term oil erosion, maintain good physical and electrical performance, and ensure reliable operation of cables in oily environments.
Cold resistance: Operates over a wide temperature range. During mobile installation, it can operate stably in the temperature range of -30°C ~ 90°C. Some specially customized models can reach a minimum operating temperature of -50°C during fixed installation. In low-temperature environments such as cold chain logistics warehouses and outdoor equipment in cold regions, cables do not become stiff or brittle due to low temperatures, maintaining good flexibility and conductivity to ensure normal equipment operation.
Weather resistance: Effectively resists corrosion from environmental factors such as ultraviolet rays and ozone. During long-term outdoor use, the outer sheath is not prone to aging, discoloration, or cracking, maintaining good appearance and performance. It is suitable for port cranes, outdoor automation equipment, and other applications exposed to natural environments for extended periods.
Excellent flame retardant performance: Flame retardant rating reaches UL94 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, effectively safeguarding personnel and equipment, and can be widely used in industrial sites with high fire safety requirements, such as electronics manufacturing workshops and chemical production workshops.
Flexible bending radius: The minimum bending radius is reasonably designed, with a fixed installation set at 5 times the cable's outer diameter; For mobile installation, when the travel is less than 10 meters, the bending radius is 8 times the cable's outer diameter; When the travel exceeds 10 meters, the bending radius is 10 times the cable's outer diameter. This flexible bending radius design allows the cable to better adapt to the installation space and movement requirements of different equipment, enabling smooth wiring and frequent bending even in tight spaces, enhancing the overall flexibility and compactness of equipment layout.
4. Product parameter details
Rated voltage: When the core cross-sectional area is less than 0.5mm², the rated voltage is 300/300V; When the core cross-sectional area is greater than or equal to 0.5mm², the rated voltage is increased to 300/500V, meeting the voltage requirements of different electrical equipment.
Test voltage: 2000V. After high-voltage testing, it ensures that the cable's electrical insulation performance is stable and reliable in actual use, far exceeding industry standards and providing solid safety assurance for equipment operation.
Insulation resistance: At 20°C, the insulation resistance ≥ 20MΩ·km. Good insulation resistance effectively prevents leakage, ensures the safety of equipment and personnel, and guarantees stable power and signal transmission.
Colors: The outer cover comes in a wide range of colors, commonly black (RAL9005), gray (RAL7001), etc. Other colors can be customized according to customer requirements, making it easy to distinguish and identify in different scenarios while meeting customers' requirements for uniform equipment appearance.
