Question 3

⠀⠀ LLC "South Power Engineering Plant" is engaged in the design, construction and maintenance of various facilities: industrial, administrative, social, etc. In particular, one of the accompanying specializations of the company is the construction of "turn-key" prefabricated modular structures in the territories of high-voltage substations in Ukraine.

⠀⠀ The specialists of our company take care of all the worries regarding the construction of industrial and manufacturing buildings: we are competent enough to do everything ourselves (or to attract proven contractors, which is also exclusively our concern).

⠀⠀ The construction of industrial facilities requires careful attention, as any detail can affect the operation of an entire industrial facility. In addition, the life and safety of employees of the enterprise and even residents of nearby territories depends on the competence of engineers and builders.

Question 4

⠀⠀ Specialists of LLC "Southern Energotechnical Plant" have skills supported by the most innovative technologies and equipment in the industry for design, laying, commissioning of cable lines for substations and their consumers with voltage up to 330 kW.

Answer

● implementation of a detailed design of a power cable installation;
● preparatory and excavation work;
● installation of trays (pipes) for cable laying;
● power cable laying;
● installation of couplings and end couplings (tips);
● measurements and testing of cable insulation;
● connecting the cable to electrical equipment.

Question 5

⠀⠀ When laying the cable at a shallow depth, the installation is carried out manually, and if it is necessary to bury the cable deeper, then a cable layer is used. Our company has two new devices from a Polish manufacturer for pulling all types of cables. This ensures compliance with the technology of the installation of cables, thereby giving confidence in the uninterrupted operation of the entire power system. If the work is carried out at subzero temperatures, then it is necessary to heat the cable. In cold weather, the cable insulation hardens and becomes less elastic, causing the risk of damage to the cable.

⠀⠀ If it is needed to lay a large number of cables, then reinforced concrete tunnels are made with a width of at least 1 meter. The cable is laid in a trench in a sinusoidal manner, avoiding crossing, with a margin equal to 13% of its total length. The margin compensates for possible ground displacement.

⠀⠀ However, it is not always possible to dig trenches. If necessary, trenchless cable laying can also be carried out, namely punctures under the road, under the railway, under the carriageway, under the building, under the river. All this is carried out using the horizontal directional drilling method.

Question 6

⠀⠀ After the agreement and approval of the design and technical documentation, a special division of our company carries out the construction of a power transmission line, consisting of the following activities:
● Breakdown of the territory for support structures.
● Arrangement of foundation pits for the construction of supporting structures.
● Carrying out foundation work and installation of inset elements.
● Delivery of supports to the object: wooden, metal, reinforced concrete.
● Assembly of support elements.
● Installation of supports and mounting of wires, insulators and other suspended fittings.
● Backfilling of soil and recultivation.
● Adjusting and entry into service.
● Commissioning power lines and drawing up an act and signing it by a special selection committee.
