Why do everyone like to choose nylon wire? What are the benefits of nylon wire? Why use nylon for outer protective layer insulation?
The reason why nylon THHN cable becomes the cable everyone loves
The density of nylon is only 83% of that of polyethylene. In addition, the thickness of the polyethylene insulation is reduced after the nylon sheath is applied, which reduces the weight of the nylon sheathed wire and the outer diameter of the finished product, thereby reducing storage costs and transportation.
Cost, reducing the labor intensity of construction. It is important that more wires or wires with larger cross-sections can be accommodated in the available space.
Nylon THHN wire has no obvious heat shrinkage, while polyethylene has obvious heat shrinkage. The combination of nylon sheath and polyethylene insulation makes the heat shrinkage of the nylon sheathed wire significantly reduced, reducing the exposed part of the conductor at the connection of the wire and other electrical appliances, and improving the safety of the line.
The main chain of polyamide has an amide group, which has good light aging resistance and long service life.
For a wire with a cross-sectional area of 1.5-10mm square, the outer diameter of the BVN wire is only 0.89 of that of the BV wire, the weight is 0.93 of that of the BV wire, and the material cost is only 0.98 of that of the BV wire. It can be seen that the performance and price of the BVN wire are superior. on BV wires.
The insulation thickness of small gauge wire is only half that of full PVC wire. The thickness of the nylon sheath is only 0.1-0.15mm.
