Completion of Gas-Insulated Switchgear Delivery for Mexico Tamaulipas Project to Support Latin America's New Energy Grid Construction

Recently, a leading domestic gas-insulated switchgear enterprise announced that 20 sets of new combined gas-insulated switchgears supporting the wind farm in Tamaulipas, Mexico have been fully produced and delivered. This batch of equipment will be used in the local Huasteca-Monterrey power transmission project to support the grid connection of 1.7GW wind power resources, which is expected to reduce carbon emissions by approximately 420,000 tons annually and provide key equipment guarantee for Mexico's energy transition strategy.

According to the latest plan of Banco Nacional de Obras y Servicios Públicos, S.N.C. (Banobras), Mexico's power system will invest 624.6 billion Mexican pesos (approximately 29 billion US dollars) in grid upgrading from 2025 to 2030. As the country's second-largest wind power production base, Tamaulipas is advancing the construction of 9 new substations and the renovation of the Huasteca-Monterrey transmission line (with an investment of 3.519 billion Mexican pesos) to solve the power transmission bottleneck of 13 existing wind farms. The gas-insulated switchgear products delivered this time are precisely the core power distribution equipment of this transmission project.

The gas-insulated switchgears delivered this time adopt the latest combined structure design, integrating three core modules: lower isolation gas tank, circuit breaker room and intelligent monitoring system. It has three major technical advantages: first, the modular design reduces the equipment volume by 30%, perfectly adapting to the compact installation space of wind farms; second, the IP67 protection level ensures 20-year maintenance-free operation in Mexico's hot and humid climate; third, it is equipped with a quick grounding switch and current transformer, shortening the fault response time to 1/5 of that of traditional equipment. This product has passed the IEC 62271-203 international standard certification and can work stably in an environment of -40℃ to +70℃.

"This is our first large-scale new energy supporting project in the Latin American market," said the director of the Overseas Business Department. "Mexican customers have extremely high requirements for the environmental adaptability and intelligence level of the equipment. Our products have passed 1000 hours of continuous salt spray test and extreme temperature cycle test, fully meeting the local grid standards." According to reports, this batch of equipment also underwent grid-connected simulation tests before leaving the factory to ensure seamless connection with Mexico's National Electric System (SEN).

With the successive approval of new projects such as the Panabá 1B wind farm (with an installed capacity of 99MW), Mexico's renewable energy market is ushering in a boom period. A Spanish-speaking technical service team has been established, and a spare parts warehouse has been set up in Mexico City to provide localized support for subsequent projects. It is expected that by 2027, the company's share in the Latin American gas-insulated switchgear market will exceed 15%, becoming one of the major equipment suppliers in the region.
