Jingchu Net (Hubei Daily Net) News (Reporter Zheng Yiming, Correspondent Wang Xin) “The cable conveying equipment is operating normally, side pressure is normal, clamping force is normal, monitoring platform signal is good, continue laying.” On March 15, at the construction site of the Wuhan 220kV Duoluokou Substation cable project, State Grid Wuhan Power Supply Company Huayuan Electric Power Co., Ltd. was using new high-voltage cable intelligent integrated equipment to carry out cable laying work. It is reported that this is also the first time this set of equipment has been applied in cable laying construction projects in the Hubei region. The Wuhan 220kV Duoluokou Substation cable project, namely the Wuhan Duoluokou Northern Comprehensive Renovation 220kV line, is expected to be completed in June, with a total of 6 circuit cables and a total length of 8.6 kilometers, including over 3 kilometers of cable laying in tunnels. 
Li Tao, director of the Cable Engineering Department of State Grid Wuhan Power Supply Company Huayuan Electric Power Co., Ltd., introduced that the traditional cable laying method uses traditional conveyors combined with pulleys for laying. A single cable construction section requires 8-10 conveyors and a large number of operators and inspectors. At the same time, due to the enclosed tunnel, long-distance communication via walkie-talkies is hindered, and delayed command transmission can easily affect the quality of cable laying, posing a great challenge to on-site construction safety management. 
As a “pacesetter” in cable laying within the province and the vanguard and main force of infrastructure cable projects in the Wuhan area, State Grid Wuhan Power Supply Company Huayuan Electric Power Co., Ltd. has been continuously seeking ways to reduce construction operation risks while achieving dual improvements in cable laying efficiency and quality. After summarizing years of cable laying operation experience, conducting multiple on-site surveys to collect data, visiting multiple domestic cable equipment suppliers, participating in technical support, and conducting joint research and development, they finally developed this new high-voltage cable intelligent integrated equipment. 
On site, the intelligent laying control system platform, cable intelligent conveyors, and other equipment are intelligently linked, and the construction site is orderly. The new equipment uses an integrated communication device to ensure smooth communication among personnel at each laying node. At the same time, personnel at the central control platform can see at a glance the important parameters of cable laying, equipment operating status, and personnel situation through the display screen, and handle problems promptly. The number of construction personnel has been reduced by 40% compared to the initial plan, achieving dual improvements in cable laying efficiency and quality.
