Nylon sheath wires more than ordinary PVC insulated wire and cable has excellent electrical and physical properties: nylon sheath wires has good heat resistance, little weightlessness operation at high temperatures, the characteristics of transient thermal overload capacity, can improve the wire can be slow or reduce to escape the PVC components or migration.Nylon sheath wire and cable have the characteristics of corrosion resistance, self - lubricating and oil resistance.Compared with the same cross section PVC insulated wire and cable, nylon sheath wires and cables with small diameter, light weight, small static coefficient of friction and corrosion resistance, etc, can improve the safety and applicability of laying...
