Product original reference: Essential for electric wet spraying machines: high-strength PUR double-sheath reel cable
1. Materials and Structural Parameters
Core Selling Points: This cable features a high-strength PUR double-sheath design, providing double protection for the cable and significantly enhancing its durability. There are two options for the inner sheath: high-strength nitrile elastomer offers good wear and oil resistance, effectively protecting against friction and oil corrosion on internal components; imported PUR inner sheath performs better in weather resistance and flexibility, and can be customized according to your actual usage environment to meet the needs of different scenarios. The outer sheath uses imported PUR composite material, which, based on ordinary PUR material, incorporates reinforcing fibers through a composite process, further improving its wear resistance, tear resistance, and weather resistance, allowing it to better withstand external physical damage and environmental erosion. The conductor is made of 99.9999% pure annealed oxygen-free copper wire. After annealing, the wire's flexibility is greatly increased. During electric wet spray machine operation, the cable needs to bend and twist with the spray arm in various complex movements; this conductor can easily handle such actions without breaking, while the ultra-high purity ensures excellent electrical conductivity, enabling efficient and stable power transmission, making the electric wet spray machine more powerful. The specially formulated TPV composite insulation layer has excellent electrical insulation properties, high insulation resistance, and can withstand high voltage impacts. Even after prolonged use, the insulation performance will not significantly degrade, ensuring electrical safety and reliability. In addition, the cable has a small bending radius, only 6-8 times the cable's outer diameter, which means that even within the limited installation space of an electric wet spray machine, wiring can be easily completed. It is compatible with various models and specifications of electric wet spray machines, offering high versatility.
Specifications Conductor: 99.9999% pure annealed oxygen-free copper wire, single wire diameter 0.08mm - 0.15mm, stranded from multiple strands, conductor cross-sectional range 0.75mm² - 16mm², meeting the power requirements of electric wet spray machines of different powers.
Insulation Layer: Specially made TPV composite material, insulation thickness 0.6mm - 2mm, insulation temperature range -40℃ to 120℃, insulation breakdown strength ≥25kV/mm, electrical performance is stable and reliable.
