OVERHEAD ALUMINIUM CONDUCTOR WIRE

by Sumitomo Electric Industries, Ltd. (SEI)

GTACSR (Gap Type Conductor) and ZTACIR (INVAR Conductor) are unique conductors by Sumitomo Electric Industries, Ltd (SEI) to up-rate existing transmission lines' capacity with similar sag by simply replacing the existing ACSR.

 

To cope with new challenges, such as harmony with the environment and application for telecommunication in several transmission line project, NS-TACSR (Noise-suppressed conductor), OPGW (Composite fiber optic overhead ground wire) and LL-ACSR/AS (Low Loss conductor) have been developed. LL-ACSR/AS can reduce transmission losses by roughly 25% compared to conventional ACSR.

 

Transmission lines adopting LL-ACSR/AS can operate more efficiently, reducing the need of electricity from fossil-fuel power stations. AS wires (Aluminum-clad Steel wires) have been used for conventional ground wire, component wire of OPGW or as the core wire of LL-ACSR/AS conductor.

SUBSEA CABLE

by Sumitomo Electric Industries, Ltd. (SEI)

Together with Sumitomo Electric Industries, Ltd (SEI), energySEA is capable of providing comprehensive services from production to installation of submarine cables, contributing to power transmission infrastructure development in Australia and throughout the world.

 

Likewise in the field of submarine cables, since having installed the worlds longest submarine cable at that time of 21km in 1921, SEI has to date manufactured and installed over 5,850km* of submarine cables. In addition to XLPE cable, SEI can supply MI (Mass Impregnated Paper Insulated Cable) and SCFF submarine cable.

 

This new technology of using PPLP MI enables us to bring further capability into cable market whereby longer distance and larger power transmission is made possible. This is because oil feeding equipment which is mandatory for fluid filled cable systems is not needed and higher temperature operation is allowed than conventional MI.

XLPE CABLE (AC AND DC)

by Sumitomo Electric Industries, Ltd. (SEI)

XLPE cable is now dominant in new transmission lines for both land and submarine applications. Utilising the broad base in technological and product development knowhow accumulated from the first pioneering steps in this field way back in the 1960's, Sumitomo Electric Industries, Ltd (SEI) has been leading extra high voltage XLPE cable development including DC application.

 

In 2000, SEI commissioned the world's first long distance 500kV AC XLPE cable system and in 2009 we successfully put into commercial operation the world first 250kV HVDC XLPE cable system in Hokkaido-Honshu Link.

 

SEI and energySEA provide full support towards our customers on "Full Turn Key" basis by providing high technology products, its related accessories and facilities from design, development and manufacturing right through to installation planning and implementation.

 

SEI has consistently provided prime quality and efficient engineering in diversified arenas such as underground, submarine and bridge crossings.
