Shanghai Suoqi PUR Polyurethane Flexible Special Cable Technical Parameter Performance
In today's rapidly developing modern industry and technology, cables, as key carriers for power and signal transmission, have performance that directly affects the stable and efficient operation of various equipment. Shanghai cable companies focus on cable research and production. Their PUR polyurethane flexible specialized cables stand out among many cable products with outstanding technical specifications, becoming a trusted choice across various industries.
1. Conductors — The Core of Efficient Conductivity
The conductors of PUR polyurethane flexible dedicated cables use multi-strand ultra-fine finely twisted oxygen-free copper wires, strictly adhering to VDE0295 CLASS 6 standards. These carefully selected and manufactured conductors possess outstanding conductivity. The multi-stranded structural design not only increases the conductor's surface area, effectively reducing resistance and improving current transmission efficiency, but also endows the cable with outstanding flexibility, ensuring stable and efficient transmission of power and signals even under complex conditions involving frequent bending and twisting. Whether in industrial equipment requiring high-power power supply or in electronic instruments with stringent requirements for signal transmission accuracy, the conductors of this cable fully utilize their advantages to ensure stable operation of the equipment.
2. Insulation — a safe and stable barrier
Insulation materials are an important guarantee of cable performance. This cable uses a highly mechanically enhanced eco-friendly PVC mixture as the insulation material. This material not only has excellent electrical insulation properties, effectively isolating conductors from the outside world to prevent leakage and short circuits, ensuring safe use; It also has outstanding mechanical strength, able to withstand a certain degree of external impact and friction, protecting conductors from damage and extending cable lifespan. At the same time, the eco-friendly PVC mixture meets environmental standards, causing no pollution during production and use, reflecting Shanghai's commitment to green and environmental protection concepts.
3. Outer Sheath — armor with multiple layers of protection
The outer sheath of PUR polyurethane flexible dedicated cables is a major highlight. Made from polyurethane material, it possesses a range of outstanding properties. The outer sheath has extremely strong oil resistance, effectively resisting corrosion from oily substances in oil-filled industrial environments, preventing the sheath material from dissolving or swelling, ensuring the cable's performance is not compromised. Its high resistance to breakage and wear ensures that even during long-term use, even when frequently dragged and rubbed, the outer sheath is less likely to break or crack, greatly enhancing cable durability. Additionally, the outer sheath has excellent chemical corrosion resistance, maintaining stability in harsh environments with various chemical substances, providing reliable protection for the cable's internal structure.
4. Bending Characteristics — Flexible adaptation to complex working conditions
In practical applications, cables often need to be bent and installed under different environments. PUR polyurethane flexible cables exhibit excellent bending characteristics. For fixed installations, the minimum bending radius is only 6 times the cable's outer diameter, which means that in installation scenarios with limited space, the cable can easily achieve bent installation, saving installation space. For mobile installations, when the travel is less than 10 meters, the bending radius is 8 times the cable's outer diameter; when the travel is greater than or equal to 10 meters, the bending radius is 12 times the cable's outer diameter. Additionally, this cable can be moved over a travel distance greater than 100 meters at an acceleration of 50 m/s² and a speed of 8 m/s, and its bending lifespan exceeds 8 million cycles. Such outstanding bending performance allows it to flexibly adapt to various complex industrial automation production lines, robotic arms, and other work scenarios that require frequent bending and movement, ensuring continuous and stable operation of equipment.
5. Operating Temperature Range — Suitable for extreme environments
Different work environments have different requirements for the temperature adaptability of cables. Shanghai Suoqi's PUR polyurethane flexible special cables demonstrate strong adaptability in terms of operating temperature range. For fixed installation, their operating temperature range is -50°C to 90°C; for mobile installation, the operating temperature range is -30°C to 90°C. This wide temperature adaptability allows the cables to function normally and maintain stable performance whether in the extreme cold of polar regions, beside scorching industrial furnaces, or in outdoor environments with frequent temperature changes. It greatly expands the application range of the cables and meets the usage requirements of various industries in complex temperature conditions.
6. Flame Retardancy and Oil Resistance — A Safe and Reliable Guarantee
Safety is an important factor that cannot be ignored during cable use. PUR polyurethane flexible specialized cables meet high standards in flame retardancy and oil resistance. They meet flame retardant standards IEC60332-1-2 and EN60332-1-2, effectively preventing the spread of flames in emergencies such as fires, buying valuable time for evacuation and firefighting, and reducing losses caused by fires. At the same time, the cable's oil resistance meets DIN VDE0282 Part 10 HD22.10S1 standard, maintaining good performance even in environments exposed to oily substances without insulation degradation or sheath damage caused by oil erosion, ensuring safety and reliability in oil-based environments such as petrochemical and machinery manufacturing.
7. Rated Voltage and Test Voltage — A Reflection of Stability Performance
The rated voltage and test voltage of a cable are important indicators for evaluating its electrical performance. The rated voltage of PUR polyurethane flexible specialized cables varies depending on the conductor's cross-sectional area, meeting the power supply needs of devices with different power levels. The test voltage is usually 2000V or 2500V, meaning the cable undergoes rigorous high-voltage testing before leaving the factory to ensure its insulation performance, electrical strength, and other indicators meet high standards, allowing stable operation in real use, withstanding the impact of normal operating voltage, and providing reliable power and signal transmission channels for the equipment.
Shanghai Suoqi's PUR polyurethane flexible special cables stand out as a high-performance, reliable cable product due to their excellent technical parameters in multiple aspects, including conductor, insulation, outer sheath, bending characteristics, operating temperature range, flame retardancy and oil resistance, as well as rated and test voltages. They are widely applicable in industrial machinery, transmission and conveyance control systems, various industrial sensors, testing instruments, electronic devices, household appliances, and many other fields, providing solid support for the development of various industries. In the future, with continuous technological advancement and the ongoing upgrading of industry demands, Shanghai Suoqi will continue to uphold the spirit of innovation, constantly optimizing product performance, bringing more high-quality cable products to the market, and helping industries achieve more efficient and stable development.
