Wire & Cable ASIA – September/October 2010 42
World’s largest
reeling cable order
Cable manufacturer and supplier Tratos Ltd has won what is
believed to be the largest order in the world for reeling cable
for high-speed cranes. The Tratosflex-ESDB cable is to be
used in 38 ZPMC cranes at the latest Busan Port terminal in
Korea.
Busan Port is the world’s fifth busiest container port and
largest trans-shipment port in North East Asia. Equipment
in use at the port includes the latest generation high-speed
container cranes, which operate at speeds up to 300m/m.
Tratosflex-ESDB has been designed to combat the common
problem of twisting that affects cables reeling at high
speeds. Twisting makes cable cores elongate unevenly so
conductors on the outer layer of a strand are at greater risk
of damage. A broken cable reeling at high speed is
dangerous, and can cause extensive and costly damage to
equipment.
Tratosflex-ESDB is different from other reeling cables
available in that Tratos engineers have modified the internal
cable design, tightening the structure against the internal
relative movement to accommodate high-speed
applications. A medium-voltage rubber insulated and
sheathed drum reeling cable, Tratosflex-ESDB operates in
temperatures from –20ºC to +60ºC.
