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 Suoqi PUR Polyurethane Cable Product Details I. Core Advantages (1) Domestic High-Performance PUR Polyurethane Sheath High-quality polyether-type polyurethane material, optimized through special process formulations, has three core characteristics: Wear Resistance and Durability: Resistant to friction from sand and stones, frequent dragging by equipment, with durability superior to ordinary rubber cables, reducing maintenance costs.
Waterproof and moisture-proof: Suitable for humid environments and short-term immersion operations, providing stable power supply for underwater equipment and outdoor machinery.
Corrosion and weather resistance: Resistant to seawater, salt spray, and acidic or alkaline corrosion, not easily aging or cracking in harsh environments such as chemical plants and ports.
(2) High flexibility, strong tensile design, flexible and bend-resistant: The conductor is composed of multiple strands of fine copper wires twisted together, making it soft and easy to bend, suitable for high-frequency bending scenarios such as robotic arms and drag chain systems, and it is not easy to break over long-term use.
Tensile and pull resistance: Built-in high-strength domestic Kevlar fibers or special tensile materials can withstand the force when moving or lifting equipment, making mobile operations more reliable.
(3) Anti-Interference and Security Assurance Shielding for Anti-Interference: Optional partial shielding or overall shielding structure can effectively block external electromagnetic interference, ensuring the stable transmission of signals in automated equipment.
Safe and flame-retardant: Meets domestic flame-retardant standards, free of halogen release, has passed rigorous testing, safe and reliable to use.
2. Wide Application Scenarios Industrial Manufacturing: Suitable for robots, production line drag chains, logistics AGVs, and other equipment, meeting the power and signal transmission requirements in high-frequency movement.
Marine engineering: Resistant to seawater corrosion, can be used for port cranes, underwater exploration equipment, and cope with marine environments such as humidity and salt spray.
Mining Machinery: Wear-resistant and impact-resistant, compatible with roadheaders and mining equipment, performs stably in conditions with a lot of dust and sand.
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.
