High-performance medium voltage equipment customized for the rigorous standards of the Swiss Federal Inspectorate for Heavy Current Installations (ESTI).
Switzerland is undergoing a massive energy transition. With the phase-out of nuclear power and the expansion of hydropower and solar, the Swiss grid requires intelligent Gas Insulated Switchgear (GIS) to manage intermittent renewable loads. Our GIS systems provide the stability needed for Swiss energy providers like Axpo, BKW, and Alpiq.
In Swiss cities, real estate is at a premium. GIS technology reduces the footprint of substations by up to 70% compared to Air Insulated Switchgear (AIS). Our compact MV GIS solutions are ideal for underground substations in Basel and Geneva, where space is extremely limited.
With high altitudes and extreme temperature variations in the Swiss Alps, electrical equipment must be hermetically sealed. Our fully enclosed GIS protects against oxidation, humidity, and atmospheric pressure changes, ensuring 30+ years of maintenance-free operation.
While Switzerland is home to global giants like ABB, the demand for agility, customization, and cost-efficient Medium Voltage solutions has led many Swiss engineering firms to source from top-tier Chinese factories like Dongguan Zago Electric Co., Ltd.
Our Dongguan facility integrates the latest AI-driven design software, allowing us to move from Swiss project specifications to full 3D design and technical verification in days, not months.
Located in the heart of China's industrial hub, we have direct access to high-grade copper, precision sheet metal, and advanced sensors, ensuring no delays in Swiss infrastructure project timelines.
We use automated assembly lines and helium leak detection for GIS tanks, meeting and often exceeding IEC 62271-200 standards required for Swiss grid integration.
Dongguan Zago Electric Co., Ltd. is a professional electrical switchgear manufacturer specializing in low-voltage switchgear, medium-voltage switchgear, and integrated power distribution solutions for industrial, commercial, utility, and infrastructure applications. The company provides OEM and ODM services to electrical contractors, engineering companies, system integrators, distributors, and project developers worldwide.
Established in 2011 and located in Dongguan, Guangdong Province, China, Zago Electric operates a modern manufacturing facility covering more than 12,000 square meters and employs over 220 skilled professionals. The company combines research and development, electrical engineering, precision manufacturing, quality assurance, and technical support to deliver reliable power distribution equipment for diverse industries.
Zago Electric offers a comprehensive portfolio of electrical products, including low-voltage switchgear, medium-voltage switchgear, power distribution panels, motor control centers, distribution boards, intelligent electrical control systems, and customized power management solutions. These products are widely used in manufacturing plants, commercial buildings, renewable energy projects, transportation infrastructure, data centers, utility networks, and industrial automation systems.
The company places strong emphasis on product safety, operational reliability, and compliance with international industry standards. Advanced sheet metal fabrication equipment, automated assembly lines, precision testing instruments, and comprehensive quality control procedures are implemented throughout the production process to ensure consistent product performance and long-term service reliability.
Switzerland's railway network (SBB/CFF/FFS) is the most utilized in Europe. Our GIS solutions support traction power substations, providing reliable 16.7 Hz or 50 Hz power distribution with minimal maintenance, ensuring Swiss trains run on time.
Companies like Roche and Novartis require zero-downtime power. Our redundant RMU (Ring Main Unit) configurations ensure that laboratory and production facilities remain energized even during grid maintenance.
Connecting Alpine hydro plants to the national grid requires switchgear that can handle high-frequency switching. Zago GIS units are tested for high mechanical endurance (M2 class) and capacitive current switching.
Yes, all our Gas Insulated Switchgear products are designed and tested according to IEC 62271-200. We provide full type-test reports and can customize panels to meet specific Swiss local regulations regarding safety and grounding.
Typically, we can complete the engineering and manufacturing within 8-12 weeks. Shipping to European hubs like Rotterdam or Hamburg, followed by rail to Switzerland, takes approximately 4-6 weeks.
Absolutely. Recognizing the environmental focus in Switzerland, we are investing in "Green GIS" solutions that use dry air or alternative insulating gases with low GWP (Global Warming Potential).
We work with experienced European system integrators and service partners who provide on-site installation, commissioning, and 24/7 maintenance support for Swiss clients.
