Product details of Shanghai Suoqi polyurethane (TPU/PUR) sheathed cables
In modern industrial and various complex environmental applications, cables face rigorous challenges, placing extremely high demands on their performance and reliability. Shanghai Suo Enterprises has carefully crafted polyurethane (TPU/PUR) sheathed cables, which, thanks to their excellent material properties and advanced processes, have become the trusted choice for many industries, laying a solid foundation for stable equipment operation.
1. Outstanding performance to meet diverse challenges
(1) High temperature resistance and oxidation resistance
Ordinary plastic raw materials oxidize easily in environments above 70°C, but Shanghai Suo Qi's TPU/PUR sheathed cables demonstrate exceptional resistance to high temperatures and oxidation. TPU materials generally withstand temperatures up to 120°C. Under high-temperature conditions, the cable's electrical and physical properties remain stable, effectively preventing issues such as sheath softening and increased conductor resistance caused by excessive temperature. It is suitable for power supply and signal transmission in high-temperature workshops such as metallurgy and glass manufacturing.
(2) Super Wear Resistance
PUR materials are renowned for their excellent wear resistance and perform exceptionally well in high-flexibility cable applications, capable of withstanding over 20 million and even 50 million bending cycles. In industrial automation production lines, CNC machines, and other equipment, cables need to bend and move frequently. TPU/PUR jackets can resist friction from internal machine components. According to the Taber abrasion test (CS-17 wheel, 1000g load), the wear is minimal, greatly extending the cable's service life and reducing equipment maintenance costs.
(3) Excellent low-temperature resistance
In the aerospace field, TPU and PUR materials are highly favored for their excellent cold resistance. Such cables from Shanghai Sohke exhibit far superior transmission stability in low-temperature environments compared to other materials. Even at working temperatures as low as -40℃, the cables maintain good flexibility and electrical performance without hardening or cracking, making them suitable for power and signal connections in cold storage, polar operation equipment, and outdoor equipment in northern winter conditions.
(4) Oil-resistant, non-toxic, and environmentally friendly
Both TPU and PUR have oil-resistant properties, are not easily corroded by grease, and are odorless and non-toxic, meeting environmental protection standards. In industries such as food and beverage processing and chemicals, cables not only need to withstand oily environments but also ensure food safety and avoid contamination. The oil-resistant and easy-to-heat-seal performance of this cable ensures that its performance is not affected when frequently exposed to greasy substances, while being safe and environmentally friendly, providing reliable assurance for the production process.
(5) High strength and reliability
Tensile design: Additional tensile elements such as Kevlar fibers, aramid yarns, or galvanized flexible steel wire ropes are incorporated internally, capable of withstanding a pulling force of up to [X] N. In towing operations of heavy equipment such as port cranes and electric shovels, this effectively prevents cables from being pulled apart and ensures stable operation of the equipment.
Stable electrical performance: The insulation layer is made of specially modified materials, with a dielectric strength of ≥[X] kV/mm and an insulation resistance of ≥[X] MΩ·km (20℃). Even in harsh environments such as humidity and high salt fog, it can effectively block current, prevent leakage and short circuits, and ensure stable and safe power transmission.
2. Scientific and rigorous structural design
(1) Conductors
Uses multi-strand ultra-fine finely twisted oxygen-free bare copper wire with a purity ≥ 99.99%, compliant with VDE 0295 CLASS 5/6 standards, featuring low resistance characteristics that effectively reduce power transmission losses. The multi-strand stranded structure gives conductors flexibility and elasticity, enhancing overall cable flexibility and bending life.
(2) Insulation layer
Specially modified insulation materials combine excellent electrical insulation and mechanical properties. While ensuring high dielectric strength and insulation resistance, they also offer excellent flexibility and temperature resistance, with operating temperatures ranging from -40°C to 120°C, meeting stable operation requirements under different environmental temperatures.
(3) Sheath
The TPU/PUR outer sheath has a surface hardness of [X] Shore A, not only offering a bright appearance but also excellent wear resistance, chemical corrosion resistance, and low-temperature resistance. It tightly wraps the internal structure, providing comprehensive protection for conductors and insulation layers during cable bending, stretching, and friction.
(4) Shielding layer (optional)
For applications sensitive to electromagnetic interference, such as automated production lines and medical equipment, tin-plated copper wire braided shielding mesh layers or aluminum foil tin-plated copper wire double-layer shielding structures can be installed. Shielding coverage rate ≥85%, effectively shielding external electromagnetic interference to ensure stable and accurate cable transmission signals, meeting the equipment's strict electromagnetic compatibility requirements.
3. Diverse application scenarios
(1) Industrial Automation
Industrial robot system: On the wrist of the six-axis robot, the cable must withstand a torsion of ±180°/m. Shanghai Suoqi cable adopts a spiral winding structure design to meet its high torsion requirements; The seventh-axis track cable has a tensile strength of >150N/mm², adapting to continuous stretching during track movement and ensuring flexible and stable robot operation.
CNC machine tools and machining centers: tool magazine drag chain cables resist cutting oil penetration, with a bending radius of ≤7.5×D (D is the cable outer diameter), maintaining stability during frequent tool changes and equipment movements; The spindle cooling system cable is resistant to temperatures up to 125°C and matches a high-pressure coolant environment to ensure efficient equipment operation.
(2) Logistics automation
Sorting robot cables: The surface is coated with an anti-static layer (resistance 10^6 - 10^9Ω) to prevent packages from sticking. During high-speed sorting, the cable's high flexibility and wear resistance ensure that frequent bending and movement are unaffected, improving sorting efficiency.
Stacker crane reel cables: Resistant to vertical lifting impacts, bending lifespan >5 million cycles. In the frequent lifting and moving operations of stacker cranes, they reliably transmit power and signals, ensuring smooth logistics and warehousing operations.
(3) New Energy Industry
Lithium battery winding machine cables: Resistant to electrolyte corrosion, with UL 62 chemical resistance tested jackets. During lithium battery production, they adapt to complex chemical environments, ensuring stable equipment operation and supporting efficient production.
Photovoltaic string welding machine cables: UV-aging resistant, outdoor service life >10 years. In outdoor photovoltaic power plants, they endure prolonged sunlight exposure while maintaining good performance, ensuring stable collection and transmission of photovoltaic energy.
(4) Special Environment Operations
Offshore wind power equipment: In the connections inside offshore wind turbine towers, between the nacelle and hub, the weather-resistant and aging-resistant TPU/PUR jacket withstands harsh offshore environmental corrosion, adapts to turbine vibration and sway, and ensures stable power and control signal transmission; on offshore wind power platforms, as power and communication cables for various equipment, they maintain good electrical and physical performance in high-salt mist and humid environments.
Mining equipment: In electric shovels, mining cranes, and other equipment, cables must withstand high mechanical stress and harsh environmental conditions. Shanghai Suoqi cables' high-strength wear resistance, oil resistance, waterproofing, and acid and alkali corrosion resistance allow reliable operation under complex mining conditions, ensuring smooth mining operations.
