“…Mobility of construction production is characterized by the following features of their phases with their specific fluctuations during the development process, changing in compositions and structures ( Fig.1.). In the mobility of construction processes can be divided into 3 phases of their development [1].…”

To the special features of building production in the construction of real estate can be attributed the mobility as the ability of its elements to move over long distances in certain directions, to concentrate in necessity to be combined in the place of a construction site in the form of facilities, rational functioning under specific conditions with a capacity sufficient to ensure obtaining at a predetermined time finished product. A distinctive feature of the mobility of construction production, compared with other types of productions, is that the building object is always in the immovable state, and all the instruments of production and living labor, in a predetermined order periodically are delivered in the construction area.

“…It can be seen that the majority of existing studies primarily focus on the ground total field strength, [28,29] the electromagnetic environment characteristics surround-ing high-voltage AC and DC conductors without adhering particles, [30][31][32][33] and analysis of insulator electric field. [34][35][36] However, there are fewer studies on the electromagnetic environment characteristics on the surface of high-voltage DC conductors with varying degrees of particles adhering.…”

High-voltage transmission lines play a crucial role in facilitating the utilization of renewable energy in regions prone to desertification. The accumulation of atmospheric particles on the surface of these lines can significantly impact corona discharge and wind-induced conductor displacement. Accurately quantifying the force exerted by particles adhering to conductor surfaces is essential for evaluating fouling conditions and making informed decisions. Therefore, this study investigates the changes in electric field intensity along branched conductors caused by various fouling layers and their resulting influence on the adhesion of dust particles. The findings indicate that as individual particle size increases, the field strength at the top of the particle gradually decreases and eventually stabilizes at approximately 49.22 kV/cm, which corresponds to a field strength approximately 1.96 times higher than that of an unpolluted transmission line. Furthermore, when particle spacing exceeds 15 times the particle size, the field strength around the transmission line gradually decreases and approaches the level observed on non-adhering surface. The electric field remains relatively stable. In a triangular arrangement of three particles, the maximum field strength at the tip of the fouling layer is approximately 1.44 times higher than that of double particles and 1.5 times higher compared to single particles. These results suggest that particles adhering to the transmission line have a greater affinity for adsorbing charged particles. Additionally, relevant numerical calculations demonstrate that in dry environments, the primary adhesion forces between particles and transmission lines follow an order of electrostatic force and van der Waals force. Specifically, at the minimum field strength, these forces are approximately 74.73 times and 19.43 times stronger than the gravitational force acting on the particles.

The conceptual idea of entrepreneurship is usually based on the need to carry out initiative activities aimed at profit making (acquisition of personal income). It means production of new or improved types of goods, energy resources and services based on technological and organizational innovations in the energy industry. Ways of boosting the productive system from its lower level of organization to a higher one are substantiated. For this purpose, all the factors of the state of internal and external activity environments must constantly be within the limits of allowable entrepreneurial niches, i.e. allowable calculated values. The conceptual idea should: ensure output of products, works and services that meet the receiver’s requirements in terms of the quality, increase marketability, ensure implementation of envisaged programs, increase economic efficiency, ensure the compliance of the entrepreneur’s opportunities. Such compliance can be achieved through a detailed system development of a combination of the above factors. For example, through strategic planning of activities using entrepreneurship matrix assessment based on cluster organizational models. Rational ways of entrepreneurship development in the energy sector should be chosen on the basis of the analysis of its cluster, matrix components.
