The company has major manufacturing bases in Kansai and Kanto regions.

In Kansai, the Osaka Works produces submarine cables and power cables. In Kanto, the company has three plants in Hitachi City, Ibaraki Prefecture: Toyoura Works (manufacture of overhead transmission lines), Hitaka Works (manufacture of power cables), and Minato Works (manufacture of submarine cables).

Our cable products cover both the transmission from power plants to substations and distribution from substations to factories and homes. Staff members at each workplace understand their responsibility in sustaining social infrastructure and are proud of making high-quality products.

With this spirit in mind, JPS works in a team setting.

Recent project

Winning the order for a large-scale submarine cable system in Europe

JPS of the Sumitomo Electric Group won the contract for a high-voltage DC transmission cable system to connect England and Belgium from NEMO Link Limited, a joint venture company formed from National Grid in the UK and ELIA in Belgium. The project will build an interconnecting transmission line, 141.5 km long, connecting AC/DC converter stations to be built in the UK and Belgium. JPS is responsible for the design and manufacture of ±400 kV class cables, the world’s highest-voltage DC XLPE insulated cable, which will be delivered in 2019 after construction and commissioning. News of the adoption of the first Asian cable manufacturer in the construction of Europe’s important interconnecting lines is attracting worldwide attention.

Exchange with the local community

Visits by children of a local elementary school

Each year, JPS offers a factory tour for students of Hitachi Municipal Hitaka Elementary School. Visitors listen to a lecture on an outline of JPS and methods used to produce electric cable on the first floor of the vertical insulation extrusion line, inspect the production on the eighth floor, and take the overall view from the observation area. Serious expressions as well as brimming smiles on the children’s faces encourage us to continue providing this tour.
