1922 the world's longest cable laying

By 1922, sumitomo wire manufacturing does successfully completed the is considered to depend on the technology at that time was unable to complete the business.That is from love luca brasi county new marina the distance to the sea "four e. island" for 21 km submarine cable laying operations.

In order to prevent the smoke pollution, a refinery in 1905, migrated to unmanned island - four came through.Since then, the island's thermal coal transportation costs troublesome.The other side of the new marina has large hydropower station, if you can direct transmission, the fee can be compressed to 1/5.But, at that time the longest distance of a submarine cable laying for San Francisco 6.7 km.More than three times its distance of laying technology is without precedent in the world at that time.

Just at this point, the thermal break.So from the new marina transmission cable laying determines what you down, and from the design and manufacture of the cable to all business entrusted to the sumitomo wire laying.Sumitomo wire thoroughly investigated in Europe and the us submarine cable, brings together the experience and knowledge, the is full of innovative high performance cable.Overcame the storm caused by interruption of construction, as well as the cable fault and so on many difficulties, spent more than 20 days, completed at the time of the world's longest cable laying.This experience, let sumitomo wire manufacturing by submarine cable technology could improve the leap.
