Shanghai Suoqi is an electric wire and cable manufacturing enterprise integrating production, sales, service, and research and development. Its products cover a variety of types, including highly flexible cables and polyurethane cables, and are widely used in fields such as machinery manufacturing and industrial robots. The following is an introduction to the selection methods for highly flexible cables and the advantages of polyurethane cables:
Selection Methods for High-Flexibility Cables
Determine electrical parameters: It is necessary to clarify the current, voltage, and power required for cable use on equipment, to determine the cable core cross-sectional area and number of cores, and also to determine whether shielding is needed and whether it is split or fully shielded.
Consider movement speed and distance: The speed at which cables move directly affects their service life. Before purchasing, understand the speed of cables in the equipment to help manufacturers choose suitable materials to ensure service life. At the same time, determine the usage distance of the entire cable.
Clarify the bending radius: The size of the bending radius is related to the cable's service life. The smaller the bending radius, the stricter the cable requirements, so higher-quality materials should be chosen to meet bending needs.
Pay attention to the usage environment: If the usage environment requires oil resistance, waterproofing, acid and alkali corrosion resistance, and resistance to high and low temperatures, cables with appropriate outer sheath materials should be selected. For example, in oil-stained environments, highly flexible cables with polyurethane outer sheaths can be chosen.
Consider internal structure: conductors can generally be multi-stranded ultra-fine stranded oxygen-free bare copper wires; insulation materials can be mixed elastomers nitrile / TPE; filling materials should be tensile and ensure cable roundness; stranded wire structures can use anti-twist layered or grouped gap filling; shielding layers can mostly use tin-plated copper mesh braided shielding; and tensile-resistant materials such as polyester or aramid wires can be added inside the cable as needed.
Advantages of polyurethane cables
Excellent resistance to high and low temperatures: It maintains good performance in both high and low temperature environments, operating normally in environments from -40°C to 90°C, suitable for extreme environments.
Strong corrosion resistance: It can withstand various chemical and physical erosions, and can be used in harsh environments such as oil stains, acids, and alkalis, extending the cable's service life.
High mechanical strength: It has excellent impact and bending resistance, maintaining good performance in various complex environments, suitable for high-stress environments.
Excellent insulation performance: Effectively prevents electrical leakage and interference, with broad application prospects in power transmission and communication.
Good environmental performance: Compared to traditional plastic cables, polyurethane cables have a lower environmental impact during production and use, and do not contain harmful substances such as lead and cadmium, reducing the risk of injury and enhancing cable safety.
Strong Flexibility: Can be customized for production according to different usage scenarios to meet diverse user needs
