TEPCO have already constructed the first Japanese 1,000kV overhead transmission
lines to meet the requirement of steadily increasing power supply. We have
overcome various kinds of technical difficulties in design and construction
primarily caused by extra high voltage operation, the scale of equipment,
and geological and climatic condition. This experience has been reflected
to the realization of highly reliable and reasonable overhead transmission
facilities. Making full use of such a wide range of expertise, TEPCO can provide
high quality consultancy services on conceptual design, detailed design, and
Electric transmission lines pass through a variety of areas. Foundations
supporting the conductors and tower are selected properly in accordance with
external load, topography and geology. Typical types of foundations are described
below. We can evaluate each foundation's bearing capacity.
As the bond part between the tower and foundations requires a reliable load
transfer, we have developed the bond method with high reliability in accordance
with various types of foundations. The bond capacities between the tower member
and the foundation are evaluated by specifying the failure mode through model
We consider the protection of the natural environment through our re-forestation
of the area where plants were initially cut for construction work. The re-forestation
is made with native plants, and also can be adopted for special conditions,
for example, high altitude or cold climates.
We can offer engineering services mentioned above.
