Shanghai Suoqi Cable Co., Ltd. has been deeply engaged in the field of special flexible cables. The following provides a professional interpretation of polyurethane cables from three dimensions: material structure, performance advantages, and application scenarios.
1. Materials and Structural Parameters
Shanghai Cable Company Polyurethane Cable (TPU Sheathed Corrosion-Resistant Cable) Product Details In the industrial field, the performance of wires and cables directly affects the stability and safety of equipment operation. With years of deep industry experience, Shanghai Cable Company has launched polyurethane cables (TPU sheaths) specifically designed to handle complex and harsh environments. With outstanding corrosion resistance and comprehensive advantages, they have become the trusted choice of many enterprises.
1. Outstanding Features to Meet Harsh Challenges (1) Exceptional Corrosion Resistance Chemical Media Protection: TPU sheaths demonstrate extremely high resistance to acids, alkalis, salt solutions, and various organic solvents. Whether in 30% 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 structure intact, preventing swelling and brittleness, ensuring stable operation of cables in highly corrosive environments such as chemical, electroplating, and pharmaceuticals.
Hydrolysis Resistance and Resistance to Microbial Erosion: Made of polyether TPU material, it has excellent hydrolysis resistance, and its performance will not decline due to hydrolysis reactions even when exposed to long-term high humidity or underwater environments. At the same time, it effectively resists microbial erosion, 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 treated with a special formula and process, resulting in excellent wear resistance. According to the Taber abrasion test, under the conditions of a CS-17 wheel and 1000g load, the wear volume is extremely low, far superior to ordinary cable materials. In industries such as mining and metallurgy, where cables frequently face friction with sand and stones or equipment dragging, this can significantly extend cable service life and reduce replacement costs.
Excellent Mechanical Performance: TPU has high tensile strength and tear resistance, capable of withstanding significant tension and external impact. With carefully designed internal conductor structures and reinforcing elements, the cable can withstand a tensile force of up to [X] N/mm², effectively coping with mechanical stress from equipment movement and vibration, ensuring that power and signal transmission are not affected.
(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 and other low-temperature 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 (up to 130°C for some special models), the electrical and mechanical performance of the cable remains stable, the TPU sheath does not soften or deform, maintaining normal insulation and protective functions, meeting the wiring requirements in high-temperature environments such as near high-temperature furnaces and engine compartments.
2. Precision Structure, Ensuring Reliable Quality (1) Conductor Uses multi-strand ultra-fine meticulously twisted oxygen-free bare copper wires (meeting VDE 0295 CLASS 5/6 standards), with a purity of over 99.99%, ensuring low resistance and excellent conductivity, reducing energy transmission loss, and improving power transmission efficiency. At the same time, the multi-strand twisted structure gives the conductor outstanding flexibility, accommodating bending and twisting requirements of the cable in complex environments.
(2) Insulation Layer Specially modified insulation materials have high dielectric strength, with values reaching or exceeding ≥[X] kV/mm, and good insulation resistance, with insulation resistance ≥ [X] MΩ·km at 20°C. This enables the insulation layer to effectively isolate currents between conductors, preventing leakage and short circuit risks. Its excellent corona discharge resistance allows stable operation in high-voltage, strong electric field environments, ensuring safe power transmission.
(3) Sheath: Imported polyether-type TPU as the outer sheath, with 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, facilitating line identification and management.
2. Performance Technical Indicators
Rated voltage 300/500V to 0.6/1kV; minimum bending radius 6D (D is the outer diameter of the cable); applicable temperature range -40℃ to 90℃; high tensile strength, excellent wear resistance, and long-term stable operation under harsh conditions such as oil contamination and humidity.
3. Application Scenarios
Polyurethane cables are widely used in industrial automation, lifting and transportation, ports, and terminals.
