High-performance surge arresters and electrical components engineered for tropical climates.
As a leading Surge Arrester Supplier in Costa Rica, we recognize the unique challenges faced by the local power sector. Costa Rica is world-renowned for its commitment to renewable energy, with nearly 100% of its electricity generated from hydro, wind, and geothermal sources. However, the country’s tropical geography and frequent lightning activity in regions like the Central Valley and Guanacaste demand robust protection for electrical grids.
Whether you are managing a utility network for ICE (Instituto Costarricense de Electricidad), securing a private hydroelectric project, or protecting sensitive equipment in the Free Trade Zones (Zonas Francas) of Heredia and Cartago, the reliability of your surge protection is non-negotiable. Our Zinc Oxide (ZnO) surge arresters are specifically designed to withstand high humidity and extreme weather patterns common in the region.
Specialized surge protection for medical device manufacturing and tech centers in Costa Rica's industrial parks, ensuring zero downtime.
Protecting the vast network of wind turbines and solar farms that power Costa Rica's green economy.
Reliable power components for coffee processing plants and export-focused agriculture across Alajuela and Puntarenas.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. We are a power technology enterprise integrating research, development, production, sales and service. The predecessor of Wenzhou Shuguang Fuse Co., Ltd. was "Yueqing Shuguang Fuse Factory" established in 1992.
With over three decades of expertise, we have become a global benchmark for high-voltage electrical components, serving critical infrastructure from Asia to Latin America.
Our commitment to excellence as a surge arrester supplier is backed by rigorous international testing. We understand that Costa Rican engineers demand compliance with both IEC and ANSI standards to ensure grid stability.
The highest technical performance meets the ANSIC37,42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, IEC60282-1, IEC269-2 and GB15166.1 standards. Our quality assurance system is complete and has passed ISO9001: 2000 quality system certification.
Leading the way in smart grid protection and sustainable electrical infrastructure.
Our products are exported to various provincial power companies in China and a complete sales network has been formed throughout the country. New high-voltage fuses and surge arresters are exported to Southeast Asia, the Middle East, Africa, Europe, and increasingly to Latin American markets like Costa Rica and Panama.
The trend in Costa Rica is moving towards "Smart Grids". We are developing next-generation arresters with monitoring capabilities to help utilities predict maintenance needs and prevent outages before they happen in remote rainforest regions.
While vigorously developing new products, we have always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system. We can customize production for specific user needs in the Costa Rican market.
Tested in the most demanding environments to ensure power continuity.
Wholesale solutions for electrical contractors and utility providers.
For businesses in Costa Rica, choosing the right surge arrester supplier is more than just a procurement decision; it is about risk management. The high density of lightning strikes in the mountainous terrain of the Cordillera Central can lead to devastating equipment failure if protection is inadequate.
The company adheres to the principle of "Development by science and technology, and survival by quality". We sincerely welcome customers from home and abroad, especially our partners in Costa Rica, to discuss cooperation and work together for the prosperity and development of the electric power industry.
