In modern cities and even small settlements, cable communications laid by air are rarely found. For the most part:
- high voltage wires.
- Wending Internet connection.
- Cable television and telephony.
They are laid in the underground method through special channels (mines), and for greater protection and ease of operation, pipe is stiff double-walled plastic, made in the form of a corrugated product. She performs several functions that we will talk about in more detail.
Protective function
A corrugated plastic pipe for laying cable products is made from polyethylene PDD. It is used for electrical communications with a voltage of up to 1 sq. The wiring laid in it is guaranteed to be protected from:
It has a fairly long operational service life (more than 25 years) therefore can be used to lay communications in the flood (monolithic) concrete structures.
light installation and ease of operation
The manufacturer’s use of the “corrugation” principle in the manufacture of hard double -walled pipes for laying cable highways, allows you to easily lay them in prepared trenches, mines or forms for pouring concrete. It is enough just to unwind the pipe along the given length of the highway, regardless of the existing turns or slopes (up to 90 degrees or more), and connect the joints with special hermetic components.
In case of damage or malfunction of the cable, repair services will not have to completely open the installation channel. The necessary segment of the cable is easily dismantled, and then a new way is installed by “stretching” through the protective pipe.
You can get more detailed information about the types and technical specifications of hard cable pipes using the company website that supplies this type of product to the domestic market.
