The article considers the issue of choosing the optimal construction arrangement of cable lines with a voltage of 10 (20, 35) kV with cross-linked polyethylene insulation. The options for using three or single-core cables laid in a triangle or in a plane are analyzed. The methodological basis of the work is the principle of minimizing the expected costs, taking into account both capital investments and annual costs, including losses of electrical energy in cables. Within the framework of the study, a nomogram of economic intervals was scheduled, which makes it possible to determine the optimal

Problem statement. In recent years, the problem of replacing copper-core fiber-optic cables has become particularly relevant. This is due to two factors: first, the prospect of introducing unmanned vehicles and the development of electromagnetic microwave weapons that can disable electronic equipment for almost any target at a distance of 10 km or more, and second, the growing need to reduce the delay of transmitted signals on the network and increase the volume of information transmitted in these networks. The article describes the construction of onboard cable networks using fiberoptic cable

Traditional microwave communication systems can no longer support high bandwidth demand. Telecommunications companies in the country are therefore investing huge sums of money in laying underground fiber cables for their backbone network. The challenges these companies face in laying optical fiber cables include inaccessibility in the 4 major cities. These cities have already developed infrastructure i.e. buildings and roads . Therefore digging and laying cables are very difficult if not impossible in some suburbs. In such areas, the companies are forced to depend on microwave links. Again, du

Long-distance submarine cable systems, such as the transoceanic system, generally consist of a series of cables and repeaters. Repeater units are spaced at regular intervals to boost the attenuated optical signal and presently contain optical amplifiers in a pressure vessel made of copper alloy. Since the repeater unit is more massive than the cable, it pulls the cable catenary locally toward the seabed. In the 1990s, several studies numerically simulated cable behavior in the water and showed that the seabed slack runs short, and the seabed cable tension increases just before the repeater rea

For this new structure, the deformation relevance between adjacent substructures results in a nonindependent and stable union.

The present article discusses the problem of the technical and economic efficiency of using materials with increased thermal conductivity when filling trenches of power cable lines. The specific thermal resistance of the soil significantly affects the permissible cable currents and, as a result, the choice of their cross-section. When the soil dries out or it is initially of high thermal resistance, the carrying capacity of the conductors decreases, which often forces the use of cables with a larger cross-section to provide the required load current.

Currently, global trends in the development of medium voltage cable networks are aimed at the introduction of cables with cross-linked polyethylene insulation. Such cables are innovative products of domestic cable manufacturers. Most often, single-core cables are laid in parallel in one plane. The article analyzes a number of significant features of cables with cross-linked polyethylene insulation, which affect the thermal regime both in working condition and in emergency operation, among which - the dependence of thermal conductivity and heat capacity of polymer insulation on temperature.

AbstractA remotely operated vehicle (ROV) can install submarine cables along a planned route accurately, thereby deploying cabled seafloor observatories at the intended locations. In this study, we developed an ROV-based cable-laying system. Its manual and automated versions have been successfully used for the installation of the Dense Oceanfloor Network system for Earthquakes and Tsunamis (DONET). The automated cable-laying system shows many advantages; for example, the cable-laying speed increased by approximately 0.1 knot from 0.5 knot, and the number of operators was reduced by half. Thus,

This paper presents a semi-analytical approximation for a two-dimensional (2D) tension analysis of submarine cables during laying operations. In the analysis, based on geometric compatibility relations and equilibrium equations, a set of non-linear differential equations are obtained. The present model considers effects of ocean currents, cable ship motion, pay-out rate, water depth and material properties on submarine cable behavior in water, which are crucial during laying operations. As shown in numerical examples, with consideration of currents and cable ship motion, the cable tension appe

This article analyzes the existing software applications used in the construction of schemes for laying cable routes. It is shown that such applications provide little functionality when optimizing route laying. In this study, we set out to create a software module based on an improved Dijkstra algorithm, which can be used in combination with the existing software. The developed module is capable of finding the shortest path when laying cable routes, taking into account logical and physical obstacles. The software module is implemented in Java and uses the concurrency module to parallelize cal

A quantitative evaluation of the thermal impact of electrical cables with cross-linked polyethylene insulation on the environment was carried out using the Elcut program. Analysis of the temperature field near the loaded cable line of 10 kV demonstrated high values of soil temperature that negatively affects its redox potential and living organisms. To evaluate the environmental impact of electrical cable materials, an approach has been developed that takes into account not only t

Abstract For the problem of insufficient attention to lightning protection of the outer sheath of high-voltage cable, the ATP-EMTP electromagnetic transient simulation software is used to establish a simulation model of the induced lightning overvoltage of the outer sheath of 110kV cables. The influence of factors such as the amplitude of lightning current, the distance between lightning and cables, cable length, laying method, and grounding resistance on the amplitude of induced lightning overvoltage is studied. The simulation results show that the order of magnitude of the induced lightning

Understanding the strain transfer mechanism is required to interpret strain sensing results for fiber optic cables. The strain transfer mechanism for fiber optic cables embedded in cementitious materials has yet to be thoroughly investigated experimentally. Interpretation of fiber optic sensing results is of particular concern when there is a displacement discontinuity. This study investigates the strain transfer mechanism for different types of fiber optic cables while embedded in concrete cubes, sustaining a boundary condition which features a displacement discontinuity.

Due to their compact structure and low laying cost, three-core power cables are widely used for power distribution networks. The three-phases of such cables are distributed symmetrically with a 120° shift to each other. Phase current is an important parameter to reflect the operation state of the power system and three-core cable. Three-core symmetrical power cables use a common shield, leading to magnetic field cancelation outside the cable during steady operation. Thus, traditional magnetic-based current transformers cannot measure the phase current on three-core cable non-invasively. In ord

The measurement results obtained the greater value of macrobending losses with the smaller the diameter of the winding, and the greater the number of turns. The highest value of macrobending losses in multimode cables is -1.48dB at 0.5cm d

As the scale and depth of mines increase, large deformations of high-steep slopes progressively become prominent. Compared with the ordinary cables, negative Poisson’s ratio (NPR) cables can provide a constant resistance force and high deformation inhibition during slope deformation, avoiding the occurrence of slope instability hazards. Consequently, the control effects on the toppling failures of slopes were necessary to be researched.
