Shanghai Suoqi Polyurethane Cable (TPU Sheathed Corrosion-Resistant Cable) Product Details
In the industrial field, the performance of electrical wires and cables is directly related to the stability and safety of equipment operation. Shanghai Suoqi, with years of deep industry experience, has launched polyurethane cables (TPU sheath), specifically designed to cope with complex and harsh environments, with excellent corrosion resistance
Its performance and comprehensive advantages have made it the trusted choice for many enterprises.
1. Outstanding Features to Meet Tough Challenges
(1) Exceptional corrosion resistance
Chemical Media Protection: TPU sheaths demonstrate extremely high tolerance to acids, alkalis, salt solutions, and various organic solvents. Whether in 30% concentration dilute sulfuric acid or sodium hydroxide solutions, or in environments with organic solvents such as acetone and toluene, long-term immersion maintains the sheath's structural integrity without swelling or cracking, ensuring stable operation in highly corrosive environments such as chemical, electroplating, and pharmaceuticals.
Hydrolysis and microbial corrosion resistance: Made of polyether-type TPU material, it offers excellent hydrolysis resistance. Even in long-term high humidity or underwater environments, its performance will not degrade due to hydrolysis reactions. At the same time, it effectively resists microbial corrosion, preventing cable damage caused by microbial growth, making it suitable for special fields such as wastewater treatment and marine engineering.
(2) High wear resistance and mechanical strength
Leading wear resistance index: The TPU material of the cable outer sheath is specially formulated and processed with excellent wear resistance. According to Taber wear resistance tests, under CS-17 wheels and 1000g load conditions, the wear is extremely low, far superior to ordinary cable materials. In industries such as mining and metallurgy, under frequent conditions of sand and gravel friction and equipment dragging, cable service life can be significantly extended and replacement costs reduced.
Outstanding mechanical properties: TPU has high tensile strength and tear resistance, capable of withstanding significant tensile forces and external impacts. Combined with carefully designed internal conductor structures and reinforcing components, the cable can withstand tensile forces up to [X] N/mm², effectively handling mechanical stresses caused by equipment movement and vibration, ensuring unaffected power and signal transmission.
(3) Wide temperature range adaptability
Low-temperature flexibility: Even in extreme cold environments as low as -40°C, the cable maintains good flexibility without hardening or brittleness, ensuring normal use in outdoor operations in cold regions or cold storage environments, such as in northern winters for open-pit mining equipment and cold chain logistics and transportation equipment power supply.
High-temperature stability: When the ambient temperature rises to 120°C (some special models can reach 130°C), the cable's electrical and mechanical properties remain stable. The TPU sheath does not soften or deform, maintaining normal insulation and protective functions, meeting wiring requirements near high-temperature furnaces and engine compartments.
2. Precision Structure, Forging Reliable Quality
(1) Conductors
Uses multi-strand ultra-fine finely twisted oxygen-free bare copper wire (compliant with VDE 0295 CLASS 5/6 standards), with purity exceeding 99.99%, ensuring low resistance and excellent conductivity, reducing energy transmission losses, and improving power transmission efficiency. At the same time, the multi-strand twisted structure gives the conductor outstanding flexibility, meeting the bending and twisting requirements of cables in complex environments.
(2) Insulation layer
Specially modified insulation materials have high dielectric strength, with values reaching or exceeding ≥[X] kV/mm, and also have good insulation resistance, with insulation resistance ≥ [X] MΩ·km at 20°C. This enables the insulation layer to effectively isolate current between conductors, preventing leakage and short circuit risks. Its excellent corona discharge resistance allows stable operation in high voltage and strong electric field environments, ensuring safe power transmission.
(3) Sheath
Imported polyether TPU as the outer sheath has a surface hardness of [X] Shore A, offering excellent wear and scratch resistance. The sheath tightly wraps the internal structure, providing excellent corrosion and weather protection while evenly distributing stress during cable bending and stretching, protecting internal conductors and insulation layers from damage. Additionally, sheath colors can be customized according to customer requirements, making line identification and management convenient.
(4) Shielding layer (optional)
For applications sensitive to electromagnetic interference, cables can be equipped with a double-layer shielding structure of aluminum foil and tinned copper wire. Aluminum foil shielding can effectively block low-frequency electromagnetic interference, while tin-plated copper wire braided shielding effectively suppresses high-frequency interference, with a shielding coverage rate of 85% or more, ensuring stable and accurate signal transmission in strong electromagnetic environments, such as automated production lines and medical equipment where electromagnetic compatibility is required.
3. Diverse applications to meet different needs
(1) Industrial Manufacturing
Chemical production: In the storage and transportation area of chemical raw materials, it is used to connect various pumps, valves, agitators, and other equipment, resisting corrosion from strong acids and alkalis, ensuring continuous and stable operation of production equipment, and avoiding production interruptions caused by cable faults.
Food and beverage processing: Meets food-grade hygiene standards. In food processing workshops, it is used for equipment power supply and signal transmission, resistant to frequent cleaning with cleaners and disinfectants, does not release harmful substances, ensures food safety, and meets the requirements for cable flexibility and wear resistance during high-speed production line operation.
Machining: Used in machine tools, automated production lines, and other equipment as power and control cables, it withstands frequent movement, vibration, and friction. Its high wear resistance and bending resistance ensure long-term stable power and signal supply, improving production efficiency.
(2) Energy sector
Oil and Natural Gas Extraction: In drilling platforms, refineries, and other locations, it is designed to withstand corrosion from crude oil, refined oil, and various chemicals, while also meeting the mobile power supply needs of equipment in complex terrain and harsh weather conditions, ensuring the safety and reliability of energy extraction and processing processes.
New energy industry: For example, solar photovoltaic power stations and wind farms require cables to adapt to complex outdoor environments. TPU sheaths have UV resistance, weather resistance, and wide temperature adaptability, enabling stable operation under long-term wind, sun, and alternating high and low temperatures. They connect photovoltaic panels, fans, and control systems to ensure efficient collection and transmission of new energy.
(3) Special Environment
Marine Engineering: Used for underwater robots, marine monitoring equipment, submarine cables, etc., resistant to seawater corrosion and water pressure, maintaining good electrical and mechanical performance in harsh environments with high salinity, high pressure, and humidity, enabling stable data and power transmission for marine resource exploration and marine environment monitoring.
Wastewater Treatment: In the aeration equipment, sewage lift pumps, and grille machines of wastewater treatment plants, they resist the corrosion of acidic and alkaline substances, microorganisms, and impurities in the wastewater, ensuring the sewage treatment system operates continuously 24 hours a day and providing reliable power support for environmental protection.
