Do you believe partnerships between international firms accelerate the transition to sustainable energy infrastructure?
Hanwha Solutions has signed memorandums of understanding with Zhongtian Technology Submarine Cable and Hengtong to jointly develop insulation materials for extra-high voltage and subsea applications. The collaborations were announced during the Wire China 2026 exhibition.
Why it matters
The partnerships aim to accelerate Hanwha Solutions' expansion into the high-value cable materials sector, focusing on the rapidly growing Chinese demand for extra-high-voltage power transmission and offshore wind infrastructure.
Hanwha Solutions is working with partners to validate 132kV-class wet-type insulation materials for offshore wind, building on its existing 500-kilovolt super extra-high voltage cross-linked polyethylene technology.
The players
Hanwha Solutions
A chemicals and energy materials company known for producing high-voltage cable components and sustainable recycling technologies.
Zhongtian Technology Submarine Cable
A manufacturer specialized in subsea cable systems for offshore energy and telecommunications infrastructure.
Hengtong
An international engineering and manufacturing firm focused on power and data transmission solutions.
The details
The collaboration utilizes Hanwha Solutions' expertise in specialized polymer compounds, specifically cross-linked polyethylene—a heat-resistant plastic used to insulate electrical cables. The process involves Hanwha supplying the core insulating material while partners manufacture and performance-verify cable samples. The initiative also includes a Closed Loop recycling solution designed to process used insulation materials back into the production cycle.
Timeline
September 21-24, 2026: Hanwha Solutions participated in the Wire China 2026 exhibition.
September 22, 2026: The company signed formal memorandums of understanding with Zhongtian Technology Submarine Cable and Hengtong.
The Tech Race
This effort follows the established industry benchmark of 500-kilovolt cross-linked polyethylene transmission capacity. The initiative directly pits the companies against regional leaders in the high-growth sector of offshore wind power infrastructure.
These materials enable more durable offshore wind farm connections, which may lead to more reliable energy transmission from coastal power installations. Commercial availability for these specific cable materials remains dependent on successful performance verification by the manufacturing partners.
The takeaway
The move signals a concerted effort to capture market share in the rapidly expanding Chinese offshore wind sector through material-level innovation. Watch for upcoming performance verification reports from the joint cable samples as a key indicator of the partnership's success.
