The plastic channel is by far the most common way to protect the pipes and cables that are underground, both in households and gardens, and in commercial facilities, such as roads or play. While clay pipes are often used in some major commercial projects, it is equally likely that larger plastic pipes can be found in today's construction sites. The location of the channel is correctly located, there are many benefits to an underground facility. Tubes primarily provide protection from ground movements and cables or pipes from animal activities, but warns of future installation of a pipe or cable, often preventing costly damage and restoration work. At the same time, it makes it much easier to replace existing cables or even more, without the need for larger earthwork.
Although water pipes should be installed at depths regulated by the strict guidelines, other services are very different – in fact, some other rule of thumb. Although most of the services are at least 300 mm deep, the ground below ground, especially at the outer walls of the house, can be found. Therefore, it is likely that you can discover such channels as maintenance of real estate or gardening, so it would be useful to understand which service cable or pipe is carried internally.
The black wire is normally used to carry electric current. The cable in the black wire is low (less than 250V) or medium (less than 500V). Red tubes have larger voltages (greater than 500V) and never near the surface.
The yellow channel contains a gas pipe. This tube is usually made of polyethylene and the gas is placed on the inlet side of the gas meter.
Blue pipeline is suitable for drinking water. In most cases it would be a MDPE (medium density polyethylene) plumbing tube.
The gray channel is used by telecommunications providers to carry the cables. The addition of the color spectrum is green, which is the standard used by cable television companies. In the 1990s cable television boom, several miles of green canals were added to the UK cities.
The Orange Channel is reserved for commercial purposes and provides a cable signal for traffic signals. This is used for both highway and rail applications, but most often used by railway maintenance contractors. This should not be confused with standard sewage and surface water drainage pipes, which are golden yellow. The channel used for traffic signals is much brighter in orange.
The other color of the channel, which is now generally visible in purple, usually in the motorway maintenance. Delivering purple channel cables for lighting and suspended ceilings
The channel is generally available from the Builders Merchants and Civil Engineering suppliers. Most canal types come with a standard length of 6 meters long, while the sleeve and end are lightweight. Small pipelines for domestic use are usually delivered in rolls of 50 m length
