Ecology cable

Ecology cable
Environment-friendly cable

Ecology cable consists of the materials that release minimal amount of dioxin and other harmful substances when burnt. The product line also includes the "ecology and recyclable cable" that has less types of constituent material and therefore allows easy fractional recovery and enhanced recycling efficiency.

Submarine power cable

Submarine power cable
Submarine (underwater) high-voltage power transmission line

Submarine cable is used for power transmission to isolated islands and across large rivers. It is available as the cross-linked polyethylene (XLPE) or oil-filled (OF) type, and can be used for voltages up to 500 kV. Armoring and under-seabed laying of the cable are also possible to prevent damages caused by anchors or fishing nets.

Submarine power cable
500 kV PPLP-MI DC Submarine Cable for Bulk Power Transmission over Long Distances

DC submarine cables are essential for long distance bulk power transmission for international power interconnection, offshore wind power stations, and other purposes. SEI’s Polypropylene Laminated Paper(PPLP)-Mass Impregnating(MI) submarine cable can be used for international and interregional interconnection of 1000 MW or more bulk power over extremely long distances of several hundred kilometers.

High-temperature superconducting cable

High-temperature superconducting cable
Large-capacity, compact and low-loss cable

Current density in the conductor layer of high-temperature superconducting cable is nearly 100 times that of conventional cables, allowing the electric currents of several kA to be transmitted over a compact cable. Because electric resistance is almost zero in the superconducting state, transmission loss is reduced substantially.
