One of the types of electricity transmission is a cable line. They are necessary for the supply of electricity from the energy source to the consumer's electricity supply system. The cable lines can be installed in the ground, installation structures (trays) or cable lines (tunnels). Today cable lines are widely used together with overhead lines.
Installation and installation of an electric cable, as a rule, begins with the project of laying cables, check the cable discs, check the integrity of the insulation and the cables cover. There are the following ways of laying cables - manual and mechanical laying. The mechanized method, by means of cables, reduces the installation time by 30 times. The principle of the cable layer is to dig a ditch with a mechanism with special wedge-shaped knives at a predefined depth of 0.7-1.3 m, and when you move, a cable is laid out which is unplugged from the drum mounted on the cable layers. If the cable is laid under communication (trams and railways, roads, other cables, pipelines), then at the crossings the cable is laid in the pipe to protect it against various types of damage.
Laying cables in the ground, the ditch
* All electrical work is carried out at the prices indicated on the website. The minimum cost of electrical work is 1000 UAH. If the costs of electrical work and repair of electricians are lower than a certain amount, the payment will be made in the amount of minimum costs of ordering electrical work or 500 UAH.
* In the absence of a project or other documentation for the repair of premises, the appearance of the additional work is possible.
* When performing work that is not specified in the price list, the price is determined on the basis of an agreement or on the basis of an assessment in accordance with the project.
* All prices for electrical work (wiring) are marked with no material costs.
Mounting the rows
The purpose of professional work is to plan cable ways by reducing costs and ensuring a high degree of efficiency to protect the core from corrosion, damage, vibration, and temperature fluctuations. The cable path must have the smallest route in which the number of intersections with adjacent communications is reduced.
