The popularity of this method of protecting electrical wiring can be explained very simply: it has a lot of advantages and very few disadvantages. The plastic corrugation for cable routing is flexible enough to be attached anywhere, even in hard-to-reach places.
Another great advantage of this method is the fire safety of the electric corrugation. Not only does it not burn itself, the electric corrugation prevents the spread of fire, even if the wire inside it catches fire. When the wire catches on fire, the wire crimp shrinks, restricting the oxygen supply and the combustion stops.
This type of protection, such as an electric corrugation made of HDPE, has become popular all over the world because of its safety, environmental friendliness and low cost.
