Cable sewerage - keep the wires in a secluded place

Why use cable sewers?

used this device for laying fiber-optic communications, telephone and electrical wires.Cable run is laid under the ground and protects the wires from temperature changes, moisture and electromagnetic influences.In addition, the gasket provides underground access at any time for inspection, replacement and repair of the network, as well as the installation of new lines, without compromising the integrity of the pavement and earthwork.

cable installation in cable ducts allows you to create extensive communication network, regardless of terrain changes and ground facilities - roads, buildings, airports and other facilities.Wires can be routed as vertically in an apartment house and in case of emergency under the water.

Where to start equipping cable ducts?

device cable duct begins with calculations and preparatory works.First of all, you need to break the track so that the volume of construction work for the lowest and most cables are protected from corrosion, lightning strikes and other harmful influences.It is desirable that the track was possible rectilinear.

When planning a route you need to avoid underground facilities, landfills, areas with calcareous soils and sewage. Construction cable ducts involves placing cable platforms, the grouping of building length, trenching, laying of underground sections in the pipe, the device transitions across the road, the installation of metering columns, laying and installation network.

used both single and semi-detached in tube packs for cable ducts.Apply ceramic, asbestos cement, concrete, plastic or plastic pipes.After every 15-20 km of cable arranged areas, which should be smooth and dry in periods of excess moisture - spill rivers, autumn rains or melting snow.

Grouping construction lengths is performed so that the transmission quality depends on the uniformity of the electrical circuit.To this end, the wires are grouped by size length, design features, the characteristic impedance, the values ​​of working capacity and other parameters.

Methods device cable ducts

Wells cable ducts are typical and special, made of brick or concrete, are divided into the corner, communicating, junction and station configuration.For the pedestrian areas and the roadway is calculated the maximum load, and protective plates are installed.The form of the well can be anyone - from rectangular to elliptical.

If the network is not possible to lay below the freezing of the soil, using the heating cable for the water drain. This self-regulating electric heating up the tape, which protects the network from freezing.It is cut into pieces of 80 m, connected to a conventional shield or a wall outlet and is laid outside the pipe.

Designing cable ducts - a difficult technical problem, which is feasible only by specialized companies.Design Stages: obtaining specification, development and coordination of the project, obtaining permits for construction and engineering works.

Availability of qualified personnel and specialized equipment, including of cable are required for such companies.As a rule, the same company is involved in both the construction and maintenance of networks and their further reconstruction and development.
