Hanwha Solutions signed memorandums of understanding with Zhongtian Technology Submarine Cable and Hengtong to jointly develop advanced cable materials. The collaboration aims to accelerate the deployment of high-value-added insulation technology for extra-high voltage and subsea applications.
Why it matters
The partnership targets the rapidly expanding Chinese market for offshore wind power and high-voltage transmission. By providing specialized insulation materials, Hanwha Solutions looks to strengthen its presence in the global power infrastructure sector.
Hanwha Solutions showcased 500-kilovolt class super extra-high voltage cross-linked polyethylene materials during the exhibition. The project specifically focuses on producing 132kV-class wet-type insulation materials for subsea use.
The players
Hanwha Solutions
A South Korean chemical and energy company that focuses on advanced materials and sustainable technology solutions.
Zhongtian Technology Submarine Cable
A manufacturer specializing in undersea cable systems for power transmission and telecommunications infrastructure.
Hengtong
An international supplier of communication and power transmission infrastructure products.
The details
Hanwha Solutions will provide its specialized 132 kilovolt-class insulation materials and technical support to its partners, who will then manufacture and performance-verify cable samples. The company also demonstrated a new Closed Loop solution designed to facilitate the recycling of cross-linked polyethylene materials.
Timeline
Hanwha Solutions participated in the Wire China 2026 exhibition in Shanghai from September 21 to September 24, 2026.
The memorandums of understanding with Zhongtian Technology Submarine Cable and Hengtong were signed on September 22, 2026.
The Big Picture
The collaboration centers on the integration of extra-high voltage cross-linked polyethylene materials into modern power infrastructure. This development marks a transition toward more specialized insulation standards required for the increasing scale of global offshore wind power projects.
The advancement of these insulation materials could lead to more stable and efficient offshore wind power delivery for utility grids. Future applications may include cheaper and more durable subsea cables that support the transition toward large-scale renewable energy.
The takeaway
These partnerships demonstrate how chemical suppliers are moving deeper into the manufacturing supply chain for renewable energy infrastructure. The inclusion of recycling solutions suggests an increasing industry focus on circular sustainability for power cable components.
