On the drilling platforms in the South China Sea, inside the detectors in the Mariana Trench, and at the relay stations of transoceanic cables, the extreme harshness of the marine environment poses almost cruel demands on electrical equipment - high pressure, corrosion, biofouling, and long-term unmanned maintenance. The failure rate of electrical control systems in traditional marine engineering is extremely high due to salt spray corrosion, pressure changes, and biological erosion, seriously affecting the safety and efficiency of marine resource development. Especially as deep-sea exploration advances towards the 10,000-meter abyss, the reliability of the control system directly relates to the safety of equipment worth hundreds of millions of yuan.
Golden Electric, in collaboration with the National Marine Technology Center, China Shipbuilding Industry Corporation and other institutions, has spent ten years on technological research and development to create a full range of solid-state relays specifically for marine engineering. These relays have been deeply applied in fields such as marine oil and gas, deep-sea exploration, marine observation, and offshore wind power, providing a solid and reliable control guarantee for the development of the blue economy.
