Costa Rica stands as a global leader in renewable energy, consistently generating over 99% of its electricity from hydro, wind, geothermal, and solar sources. However, the transmission of this green energy faces unparalleled environmental stressors. As a premier Double-Shed type manufacturer, we recognize that the Costa Rican market requires more than just standard equipment.
Our Double-Shed glass insulators are engineered specifically to exceed IEC 60305 standards, providing the "Information Gain" needed for local utilities like ICE (Instituto Costarricense de Electricidad) to maintain 99.9% grid uptime.
Unlike standard profiles, the Double-Shed (or Anti-Pollution) design features a larger protected creepage distance. By increasing the ratio between the leakage distance and the spacing, these insulators prevent "arc bridging" during heavy rain or mist—a common occurrence in the Talamanca mountain range.
Worldwide, the shift toward Ultra-High Voltage (UHV) transmission requires materials that do not age under high electric field stress. Toughened glass, unlike polymer, offers "zero-aging" characteristics, making it the sustainable choice for the next 50 years of Costa Rica’s infrastructure.
Our factory utilizes RTV (Room Temperature Vulcanization) silicone coating on glass surfaces. This hybrid approach combines the mechanical reliability of toughened glass with the superior hydrophobicity of polymers, ideal for the most polluted Guanacaste industrial zones.
Jiangxi QOCI Electric Co. Ltd, founded in 2002 with a registered capital of 508 million Yuan, is a global powerhouse in the electric transmission industry. We serve the world-class power grid with dedication, actively participating in the construction of green energy projects across Latin America.
INNOVATION: Serving high-performance transmission projects like UHV lines.
QUALITY: Responsibility is the guarantee of quality.
SERVICE: Ensuring the safety of the power grid through fast delivery and expert technical support.
Specialized open-profile and double-shed insulators to prevent dry-band arcing caused by volcanic ash accumulation in the Central Volcanic Cordillera.
High-salinity resistance for transmission lines running along the Puntarenas and Limón coastlines, featuring U210 and U240 anti-fog series.
Aerodynamic designs that withstand high-velocity wind loads and heavy tropical downpours without losing dielectric integrity.
Solutions for San José’s growing industrial parks, where chemical pollutants require high-strength glass insulators with deep under-ribs.
The "Double-Shed" or "External Shed" profile provides a significant advantage in areas with heavy solid pollution (like volcanic ash) and high humidity. By removing dense under-ribs, it allows rain to wash away contaminants more effectively while maintaining a high creepage distance to prevent flashover.
Our U210BD and U240BD series are specifically designed with a high leakage distance-to-spacing ratio. This inhibits the formation of a continuous conductive salt-water film, which is the primary cause of line outages in coastal regions like Limón.
Yes, all our glass insulators are manufactured and tested strictly according to IEC 60305, IEC 60383, and ANSI standards. We provide full type-test reports from independent laboratories to ensure compliance with Costa Rican utility requirements.
With an annual output of 39,000 tons, we offer some of the fastest delivery times in the industry. For Central American markets, we can coordinate logistics via major ports to ensure your grid expansion stays on schedule.
