From Wharves to Markets: Wenzhou Power Supply Fully Supports the Fishing Industry

In mid-August, the fishing season opened in parts of the East China Sea, with large numbers of fishing vessels heading out to sea. As fishing operations got into full swing, electricity demand across the seafood supply chain surged. State Grid Wenzhou Power Supply Company continued to monitor the electricity needs of the fishing industry, sending staff to coastal areas to conduct inspections and safety awareness campaigns. While inspecting coastal power lines and submarine cables, the company also stepped up efforts to raise awareness of power facility protection, helping ensure safe fishing operations.

"Sir, the typhoon has just passed and sea conditions are complicated. Please do not anchor in the submarine cable protection zone when heading out to sea." While using drones to inspect power lines along the port shoreline, employees of State Grid Wenzhou Power Supply Company reminded fishermen of the relevant safety precautions.

Wenzhou has a long coastline and numerous fishing ports and wharves. Following the opening of the fishing season, large numbers of vessels head out to sea, while frequent nearshore fishing activities increase the risk of external damage to submarine cables caused by vessel anchoring, fishing nets being dragged along the seabed and offshore construction. The company has focused on three key areas — nearshore transmission corridors, submarine cable protection zones and distribution transformer areas along wharves — conducting safety awareness campaigns vessel by vessel and household by household and bringing information on power facility protection directly to fishermen.

In addition to manual inspections, the company has established an integrated protection system combining multi-dimensional inspections and centralized monitoring by leveraging digital technologies. A submarine cable radar monitoring system is used to capture images of vessels, track their movements and issue real-time risk alerts around the clock within submarine cable protection zones. If a vessel is found to have anchored or remained in a restricted area in violation of regulations, the platform immediately issues an alert, enabling operation and maintenance personnel to intervene promptly and minimize the risk of external damage through digital monitoring and control.

At major seafood markets, company staff also conducted targeted inspections of refrigeration systems, oxygen supply equipment and emergency power supplies. Infrared thermometers were used to check temperatures along market power lines and identify hidden hazards such as abnormal equipment heating. Staff also tested the sensitivity of residual-current protection devices, checked whether wiring was installed in compliance with safety standards, and focused on potential risks such as aging wires and overloaded sockets. These measures help ensure electrical safety while keeping seafood fresh throughout transportation and sales.

During the inspections, company staff also promoted safe electricity use among market vendors, demonstrating how to conduct self-checks of residual-current protection devices and sharing energy-saving tips for air conditioners and refrigeration equipment based on the markets' actual operating conditions. More than 500 copies of safe electricity-use brochures were distributed, helping strengthen safety awareness among people working in the fishing industry.

Going forward, State Grid Wenzhou Power Supply Company will continue to closely monitor weather conditions at sea and the pace of fishing operations, strengthen routine and refined operation and maintenance of coastal transmission corridors, and expand power facility protection awareness campaigns across wharves, fishing vessels and markets. Through reliable and high-quality power services, the company will continue to support the development of Wenzhou’s marine fishing economy.
