In chemical, machine tool processing, and other scenarios, cutting fluids, oil stains, and acidic or alkaline media continuously corrode cable sheaths, causing general PVC/rubber materials to age and crack quickly, greatly reducing service life. Shanghai Suoqi polyurethane cables are specially designed for such working conditions, featuring a polyether polyurethane outer sheath, conductors meeting VDE 0295 CLASS 5 standards, and TPV composite insulation, suitable for oil, acidic, and alkaline corrosive environments. The cables possess properties of polyurethane, PUR, TPU, etc., and are widely used in automation, production lines, CNC, and other fields. Shanghai Suoqi cables are factory-direct and customizable with multiple cores and specifications, with sufficient stock for nationwide delivery. For inquiries, call 13311756197.

Product Features

(2) Super Wear Resistance Properties PUR material is renowned for its outstanding wear resistance, performing particularly well in high-flexibility cable applications, capable of withstanding over 20 million or even 50 million bendings. In industrial automation production lines, CNC machine tools, and other equipment, cables need to be frequently bent and moved. TPU/PUR sheaths can withstand friction from internal components and have passed Taber wear resistance tests (CS-17 wheels, 1000g load). The wear is extremely low, greatly extending cable service life and reducing equipment maintenance costs.

(5) High Strength and Reliability Tensile Design: Internal tensile components such as Kevlar fiber, aramid yarn, or galvanized mild steel wire rope are added, capable of withstanding tensile forces up to [X] N. During towing operations of heavy equipment such as port cranes and electric loaders, it effectively prevents cable breakage and ensures stable equipment operation.

2. Scientific and Rigorous Structural Design (1) Conductor Uses multi-strand ultra-fine finely twisted oxygen-free bare copper wire, purity ≥ 99.99%, compliant with VDE 0295 CLASS 5/6 standards, featuring low resistance characteristics that effectively reduce power transmission losses. Multi-strand twisted structure endows conductors with flexibility and elasticity, enhancing overall cable flexibility and bending life.

(4) Shielding layer (optional) For applications sensitive to electromagnetic interference, such as automated production lines and medical equipment, a tin-plated copper wire braided shielding mesh or aluminum foil tin-plated copper wire double-layer shielding structure can be installed. Shielding coverage rate ≥85%, effectively shielding external electromagnetic interference, ensuring stable and accurate cable transmission signals, and meeting the equipment's strict electromagnetic compatibility requirements.

3. Diverse Application Scenarios (1) Industrial Automation Industrial Robot System: In the wrist of a six-axis robot, the cable must withstand a torsion of ±180°/m. Shanghai Cable Company uses a spiral winding structure design to meet 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.

Frequently Asked Questions

What makes polyurethane (PUR) cables so good?

PUR jackets are wear-resistant, oil-resistant, hydrolysis-resistant, and antimicrobial, with comprehensive mechanical properties superior to PVC, making them suitable for harsh conditions such as oil, humidity, and outdoor environments.

What is the temperature resistance of polyurethane cables?

Conventional polyether PUR is suitable for temperatures from -40°C to 90°C, and can be higher in the short term. When selecting, consider ambient temperature and mobile status for confirmation.
