The most economical laying in the ground. Unlike overhead lines, cable installation in the ground is not exposed to heavy snowfalls, storm winds and is not damaged by fallen trees. Cable lines to a lesser extent than vibrations, probably dangerous and interfering with electromagnetic chronometers that occur in communication, signaling, automation and telemechanics circuits of frequency power lines and contact networks of electric railways, as well as exposure to atmospheric overvoltages (lightning discharges). Cable route 10 kV . Drum roll.
Cable lines detect better, high quality and reliability of communication and signaling, more suspicious and cheaper to operate, despite the fact that their detection is detected. Damage on cable lines is much less common than in the air.
Cable route 10 kV. Urban conditions. For cable lines laid in the ground, armored cables should be in demand. Metal federal borders must have an external cover to protect against threats. If unarmored cables are laid, then asbestos-cement or PVC pipes must first be laid, which will reliably protect it from
accidental mechanical damage during discharge excavations. If the cable is armored, then its use also provides for the laying of pipes at the intersection of railway and tram tracks, highways and dirt roads, under the carriageways of streets, at the intersection with underground structures and other areas in such a way that the ends of the pipes go out 1 m. outside the intersection, as well as when entering the cable into a building or structure.
Cables are protected when they are laid in rocky soils at a depth of 0.5 m, in orchards and orchards, when laid in one trench ten-year or more signal and other areas, as well as when laid in a trench at a depth of less than 1 m of power frequencies with a voltage above 1 sq. In cases where concrete slabs or a layer of red brick are used for protection.
