LS Cable & System has established a demonstration installation of the world’s first superconducting DC cable. The company completed the installation of the 80kV superconducting DC cable at its superconducting power system center in Jeju Island at the end of October, and on 19 th November started a system demonstration that will last for six months. Superconducting cable is highly usable in congested urban areas where power demand is on the rise, while space underground for cables is already saturated with cable tunnels and conduits. A dramatic wattage increase can be achieved by simply replacing existing cables with superconducting cables. In addition, when it becomes necessary to build a new cable tunnel, the cross section of the tunnel can be reduced by over 60 percent. LSCable&Systembegan itsdevelopment of a superconducting cable in 2011, and was fourth in the world to produce an AC cable. In 2013, the company was first in the world to produce a DC superconducting cable. Conducting superconductor demo

Communication in the field

Yokogawa Electric Corporation has released a multi-function wireless adaptor, allowing wired devices that transmit/ receive digital on/off signals, or receive 4-20 mA analog signals, to function as ISA100 Wireless™ field wireless devices. Field wireless systems enable plant field devices and host-level monitoring, control, and other systems to communicate wirelessly, and can be installed in difficult-to-wire locations with the added advantage of a lower installation cost. The new adaptor will increase the variety of devices that can be used with field wireless systems, and is expected to lead to a wider use of such systems in plant operations. An all-weather waterproof and dustproof model, and an explosion proof model that can be used in inflammable gas environments, areexpected tobe released during 2015.
