electrical and thermal analyses of parallel single conductor Cable Installations
IEEE Transactions on Industry Applications, 2010Co-Authors: Patrick Y Du, X. H. WangAbstract:The unequal current distribution in parallel single-conductor Cable Installations can lead to an excessive temperature rise. This paper presents a Cable model and a procedure of coupled electrical and thermal analyses for the evaluation of the current, loss, and temperature in the Cables of concern. The Cable model and analytical method were tested experimentally on a Cable system in the laboratory. The procedure was applied to evaluate the current rating and the temperature rise in a particular single-conductor Installation. It is concluded that the parallel Cable Installation without proper Cable rephrasing derates the Cables significantly. The third-order harmonic current can cause a significant reduction of the current rating if its distortion is over 30%.

Current Distribution in Parallel Single-Core Cables on Metal Tray
IEEE Transactions on Industry Applications, 2007Co-Authors: Yaping Du, Y.z. Yuan, X. H. WangAbstract:Parallel single-core (single-conductor) Cables are employed in the backbone of building distribution systems. As power consumption in buildings grows continuously, overheating problems associated with such a Cable Installation have become a concern. This paper investigates the current distribution among parallel single-core Cables installed on metal tray in a multiphase distribution system. A general prediction method of current distribution is introduced and is validated experimentally. To analyze the current distribution under different Cable arrangements, empirical formulas of Cable impedance are presented. The current distribution associated with the local practice of parallel Cable Installations is evaluated, and recommendations for the design and Installation are presented.

ICUFN - Multihop Wireless Controlled Sensor and Actuator Network for Cable Installation System
2019 Eleventh International Conference on Ubiquitous and Future Networks (ICUFN), 2019Co-Authors: Masahiro WatanabeAbstract:A Long and heavy Cable should be carried out the Installation under the construction of plant. The current Cable Installation system drives the Cables to relax the physical stress of workers, although. That system cannot work to pull the long and chained Cable sequentially at the timing of tension triggered to the Cable head by worker. We propose the multihop wireless controlled system that works to push the Cable at the timing of instruction packets delivered by tension applied. This paper explains the adoption of multihop wireless controlled sensor and actuator network into the Cable Installation system.

Realization of a multihop wireless controlled sensor and actuator network for Cable Installation
ICT Express, 2019Co-Authors: Masahiro WatanabeAbstract:Abstract Long and heavy Cables need to be laid during the construction of plant. The present-day Cable Installation system drives the Cables through by power assistance in order to reduce physical stress on the workers. However, the system cannot pull a long and heavy Cable sequentially at the desired timing of the tension triggered onto the Cable head by the worker. To solve this problem, we propose a multihop wireless controlled system that works to push the Cable at a time set by instruction packets delivered according to the applied tension. This paper explains the design and adoption of a multihop wireless controlled sensor and actuator network into the Cable Installation system.

Development of a Coiled Tubing Cable Installation System
Welded Pipe and Tube, 2015Co-Authors: Yang ShemiAbstract:A system has been developed which installs and de-installs an electric wireline Cable in Coiled Tubing(CT) while the CT is still on the reel. This paper discuss the need for such a system, the theory used to develop this system, the various concepts considered, the system that was developed and test Installation cases. The working pressure of this Cable Installation system is 51.72 MPa(7 500 psi). This Cable Installation system reduces the cost of a Cable Installation significantly compared with previous Installation methods, and can fully meet the requiremetns of Installation Cable in long coiled tubing.

Radiation Tolerant Optical Fibers: From Sample Testing to Large Series Production
Journal of Lightwave Technology, 2011Co-Authors: Thijs Wijnands, Jochen Kuhnhenn, Kazuhiko Aikawa, Daniel Ricci, Udo WeinandAbstract:The process of selecting, manufacturing, and installing a large quantity (2500 km) of commercially available radiation tolerant specialty fibers is described. Radiation tests of various types of fibers from different manufacturers provided sufficient understanding of the radiation effects to select the best performing fiber type. Systematic verification of a sample of each preform assured a constant quality of the series production and allowed assessing the impact of small variations in the manufacturing process on the radiation hardness and the optical transmission characteristics. The fiber Cable Installation technique based on microjetting and plastic Cable ducts has been validated for areas with high levels of radiation.
