1. Materials and Structural Parameters
Using special corrosion-resistant sheath materials can effectively resist corrosion from various chemical substances such as acids, alkalis, salts, and organic solvents. Materials such as fluoroplastics and neoprene rubber can work stably for a long time in highly corrosive environments.
The conductor is made of high-purity oxygen-free copper, which has low resistance and high conductivity, ensuring stable transmission of power and signals, and reducing energy loss and signal interference. At the same time, the insulation material has high insulation resistance and withstand voltage performance, ensuring the electrical safety of the cable.
Generally, multi-stranded twisted oxygen-free copper wires are used. Depending on the specifications and use of the cable, different conductor structures can be chosen to meet different current carrying capacities.
Use chemical corrosion-resistant insulating materials, such as cross-linked polyethylene, polytetrafluoroethylene, etc., to provide reliable electrical insulation performance.
Optional metal braided shielding (such as tinned copper wire braid) or aluminum foil shielding, used to suppress electromagnetic interference, improve the cable's anti-interference capability, and ensure the accuracy of signal transmission.
Use corrosion-resistant sheath materials, such as neoprene and fluororubber, to tightly wrap the internal structure of the cable, providing mechanical protection and chemical resistance.
With special structural design and material selection, it can withstand millions of bending cycles without easily breaking cores or skin breakage, making it suitable for high-dynamic sports environments.
Multi-strand fine oxygen-free bare copper wire or tinned copper wire twisted together, meeting the conductor standards for high-flexibility cables, providing good flexibility and conductivity.
Uses high-quality insulating materials such as PE and PVC to ensure good electrical insulation performance while maintaining some flexibility to accommodate cable bending.
Tensile fibers (such as Kevlar fibers) or steel wire ropes are installed inside the cable to enhance its tensile strength, meeting mechanical requirements for high-dynamic motion environments.
2. Performance Technical Indicators
In chemical production, there are often strongly corrosive chemicals such as acids and bases. Corrosion-resistant cables can be used to connect chemical reaction vessels, monitoring devices for pipelines, chemical pumps, and other equipment, ensuring stable transmission of signals and power, without being affected by the corrosive environment on the cables.
During sewage treatment, the wastewater contains various corrosive components. Corrosion-resistant cables are suitable for mixing equipment, level meters, and pumps connected to sewage treatment pools, effectively resisting sewage corrosion and extending cable service life.
It has certain tensile, compressive, and wear-resistant properties, and even in complex installation and usage environments, it is not prone to mechanical damage, ensuring the normal use of the cable.
It can adapt to different climate conditions, maintaining stable performance whether in high temperatures, low temperatures, humid or dry environments, and is not prone to aging or cracking.
In high-speed drag chain operations, such as automated warehousing and logistics equipment, woodworking machinery, glass machinery, and more, PUR polyurethane cables can operate stably and continuously in drag chains for long periods thanks to their excellent bending resistance, ensuring reliable equipment operation.
PUR polyurethane sheaths have high wear resistance, effectively resisting friction and scratches, extending cable service life, and maintaining good appearance and performance even in rough working environments.
It has good resistance to various greases, lubricants, and common chemicals, allowing normal use in environments contaminated by oil and chemicals, maintaining stable cable performance.
Made from PUR polyurethane material, typically gray or black, with good wear resistance, oil resistance, and chemical corrosion resistance.
3. Application Scenarios
For example, in offshore oil platforms and seawater desalination equipment, where seawater is highly corrosive, this cable provides reliable line connections for underwater detection equipment, marine monitoring instruments, and platform electrical systems, ensuring normal operation of equipment in harsh marine environments.
Widely used in robotic arms, automated production lines, CNC machine tools, and other equipment, they meet the power and signal transmission needs during frequent movement and bending processes, such as servo motors and sensors connected to robots.
