Abstract:

One of the objectives of the SCARLET project is to develop and industrially manufacture superconducting MgB<sub>2</sub> cables cooled by liquid hydrogen. The ex situ powder-in-tube MgB<sub>2</sub> wires manufactured by ASG are considered for the cable design that can carry DC current of 20 kA. These braided superconducting wires, containing brittle filaments, require high current. Thus, the study of the electro-mechanical properties of MgB<sub>2</sub> wires is crucial for the cable design and its functional use. Superconducting wires have to withstand all the stresses applied du

Abstract:

The original design model for defining the attenuation of manufactured cables was derived and fitted to experimental data. The model relationship connects attenuation with some parameters of cable design and testing: copper wire, aluminum, and insulation thicknesses, cable impedance, test frequency, and lay length. Defined expression was used for Monte-Carlo simulation of the cable attenuation prediction. With developed MATLAB program, a special graphical user interface was created. After assigning the desired parameters, this interface generates a plot with distribution of the attenuation val

Abstract:

During manufacture, handling, transportation, installation and operation, mechanical overstress can affect the electrical and thermal properties of the conductor. As the wires in general are made of copper, which is a very plastically deforming material, these stresses will gradually generate plastic deformations of the copper until the wires start to fail. The objective of this article is to study, by numerical modeling (using Comsol and Abaqus), the impact of damage mechanisms on the electrical and thermal properties of a submarine cable phase. The influence of plasticity and gradual copper

Context. Today, the leading cable production plants in many countries of the world manufacture single- and multi-module designs of fiber-optic cables (FOC) with different protective covers and the number of fibers. This creates a wide range of possible FOC models for different consumer (buyer) requirements. However, the lack of openness of prices for FOC for the consumer, in particular for the project organization, and the desire of the manufacturer to save on production creates a need for the development and research of a method for evaluating the effectiveness of FOC of a multi-module design

First, we hypothesized that the temperature is high when the density is high due to the overlap of the hot wires or when there is a thermal insulating material.

Abstract:

Abstract The hydrocarbon industry leans heavily upon advanced technologies to extract oil and gas from greater depths and in harsher environments. The challenge to electronics manufacturers and designers is to make complex electronics work at the high temperatures, vibration, and extreme pressures encountered in these locations. Among the more critical electronic systems required for high temperature down-hole operations is high efficiency switching mode power supplies (SMPS). The use of high frequency switching permits not only decreasing the size of inductors and capacitors in the circuit de

Abstract:

Experts point out that “A quarter of all overhead power lines outages are caused by birds, and 86% of grid companies name birds as main problem”. Unfortunately, this is the key factor in the problem of mass death of birds: power engineers are forced to protect lines from birds, while the issue of protecting birds from lines has lower priority. In any case, it all comes down to one question: what should we do? Solution 1: cable lines. Pros: + Absolutely safe for birds. Cons: - Not possible to apply to currently existing lines, only new construction is possible, - High costs of underground works

Abstract:

Thick-walled stainless steel optical tubes used in steel armored cables sustain severe forces arising from the axial strain of the bulk cable, core pressure caused by the squeezing effect of the helically wrapped armor wires, and external forces on the cable. The conditions which result in collapse of the optical tube are investigated by applying established plasticity theory and then extending this theory to develop new equations for the case of a work-hardening material. The theoretical criteria for the onset of tube collapse are identified. Theoretical, experimental, and field results are t

Abstract Experimental tests on the type-approval of motor vehicles with regard to safety belt anchorages, ISOFIX anchorages and ISOFIX top anchorages have been carried out in accordance with Regulation No. 14 UNECE [1]. From the design stage, the safety belt anchorages must comply with the requirements for the installation of a safety belt and reduce slipping and damage to the belt while wearing it. These can be components of the seat structure or of the body’s resistance structure, which have the role of fastening the seat belts. The position of the anchor points is determined by the R point.

The problem of high-voltage power cables is associated with complex technological processes in their manufacture. One of the main processes in the manufacture of cables is extrusion. There is a huge number of parameters (known as process parameters) at the stage of extrusion process that directly affect the performance of isolation and cable as a whole. It is shown that the important parameters of the process of extrusion are the melt temperature, speed, pressure, screw speed, the type of matrix used and the cooling medium in the extruder. The temperature and pressure of the melt are among the

Abstract Conductor on Round Core (CORC®) wires and cables, constructed from multiple layers of helically wound REBa2Cu3O7−δ tapes, are a promising cable technology for high field magnet applications. An important feature of high-temperature superconductor cables is the ability to share current between conductors, allowing current to bypass drops in I c and minimizing the risk of hot spot formation, which could lead to potential burnout in the superconductor. In contrast to stacked-tape cables, which have continuous contact between tapes, in CORC® the transfer points occur at discrete tape cros

Twenty-five-year-old, reused CFRP wires (recovered from two dismantled bridge cables) were examined with regard to any possible drop in strength or stiffness due to aging and then processed into two bridge strengthening cables. The new anchorage and cables were tested to their tensile capacity (giving on average 1.833 MN) in two full-scale instrumented experiments.
