| description | Uninterrupted provision of consumers with electrical energy of appropriate quality is the main task of building a power supply network. The required level of electricity quality is achieved by choosing the parameters of the elements of the power supply network, which is conditioned by tasks conditionally divided into technical and economic ones. This article presents the results of studies of the dependencies of the cost of the cable on its parameters: the cross-sectional area, the maximum allowable long-term current. The correlation coefficient between the cost of the cable and its cross-sectional area is determined, expressions describing this dependence are proposed (in prices of 2023). The method of naming squares was used to find the linear regression equation. The use of a deflator index to predict the cost of a cable is proposed. The dependences of the cost of 1 m of cable on the value of the maximum allowable long-term current when laying one cable and when laying several cables in parallel with a smaller cross-sectional area are considered. Based on the results of the study, the following conclusions were drawn: about the existence of a practically functional relationship between the cost of cables and the cross-sectional area of the core, which makes it possible to predict the cost for cables; about the advantage of using the method of parallel laying cables with a smaller cross-sectional area compared to laying one cable, which is especially significant for cables with a large cross-sectional area. It is noted that the specific costs of 1 mm2 of cable (in terms of one core) are almost the same for single-core and multi-core cables and practically do not depend on the cross-sectional area of the core. It has been established that the value of the specific cost of transmitting 1 A of the maximum continuous permissible current increases with increasing cross-sectional area for cables with polyvinyl chloride insulation. |
