Nylon THWN Wire Coating Material Introduction
Introduction of PVC Insulated Nylon Clad THWN Wire
PVC insulated nylon sheathed cable (THHN cable)is a new type of cable formed by reducing the thickness of the polyethylene insulation and adding a thin nylon sheath on the base of the original PVC insulated sheathed cable.
Excellent performance of nylon wire.
Nylon has good physical and mechanical properties. Its tensile strength is more than 5.5 times that of polyethylene, and it has good wear resistance, which increases the surface mechanical strength and surface hardness of nylon-coated wire, so the nylon sheath is also called "soft armor".
Nylon also has self-lubricating properties, which can reduce the friction factor on the surface of the wire, facilitate the construction of the wire through the pipe, prevent the wire from being damaged, and greatly improve the construction efficiency and quality. from work.
Nylon wire has good stability. Nylon wire has two forms: glass table and viscous flow state, there is no high elasticity state, and there is no obvious deformation under the high temperature of 150 degrees Celsius.
This protective nylon layer improves the overall level of heat resistance of the cable, especially the thermal change performance under instantaneous overheating.
Nylon cable is resistant to most non-active solvents, such as oil, hydrocarbons, lipids, etc. Polyvinylidene will swell, age or crack under the action of grease, which greatly expands the application scope of nylon-sheathed cables.
