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.

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.
