As one of Southern Europe’s most critical industrial hubs, Barcelona’s power grid faces a unique trifecta of challenges: high atmospheric salinity from the Mediterranean Sea, industrial particulate matter from its dense manufacturing zones, and the rapid integration of renewable energy sources from the Catalan hinterland.
The Double-Shed Type Glass Insulator has emerged as the gold standard for this region. Unlike standard profiles, the double-shed design (or external shed) provides a superior leakage distance-to-spacing ratio. This is critical for preventing "Pollution Flashover," a phenomenon common in coastal cities where salt fog creates a conductive layer on insulator surfaces, leading to catastrophic grid failure.
Engineered to resist salt spray corrosion and conductive fog accumulation in areas like the Port of Barcelona.
High self-cleaning properties ensure that cement dust and industrial emissions don't cause tracking or leakage currents.
Founded in 2002 with a registered capital of 508 million Yuan, QOCI has spent over two decades perfecting the art of toughened glass insulation. Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is reflected in our massive production scale and technical patents.
Our facility in Luxi County, Pingxiang, serves as a global hub for high-voltage infrastructure, supplying world-class power grids with dedication to green energy construction.

The global insulator industry is shifting toward "Smart Grids" and "Zero-Maintenance" infrastructure. For global procurement officers and grid engineers in Barcelona, the selection of Double-Shed types represents a strategic investment in lifecycle cost reduction.
Traditional glass insulators are being upgraded with RTV (Room Temperature Vulcanization) Silicone coatings. This hybrid approach combines the mechanical strength of toughened glass with the extreme hydrophobicity of polymers, offering an "install and forget" solution for high-pollution zones.
All our double-shed products are manufactured strictly in accordance with IEC 60305, IEC 60383, and ANSI standards. For Barcelona-based projects, we ensure full compliance with EU energy directives and local grid specifications used by major utilities like Endesa and Red Eléctrica de España.
We offer localized support through streamlined logistics to the Port of Barcelona. Our "Direct-from-Factory" model eliminates middlemen, ensuring that large-scale infrastructure projects receive cost-effective, high-quality components with verified batch testing reports.
Customized Engineering for Every Environmental Challenge
Leakage distance exceeds IEC 60305. Features shallow, well-spaced small ribs for effective self-cleaning by wind or rain. Ideal for inland Barcelona regions.
Long, widely-spaced under-ribs prevent arc bridging. Particularly effective in salt fog coastal areas and industrial polluted zones.
Design with two external ribs eliminates under-ribs to reduce pollution build-up. Performs exceptionally in industrial and saline soil environments.
Barcelona’s proximity to the sea creates high humidity and salt deposits. The Double-Shed design increases the creepage distance and provides a more open profile that allows rain to wash away pollutants naturally, reducing maintenance frequency.
All our products comply with IEC 60305, IEC 60383, and IEC 60120. We also hold ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, ensuring total reliability for Barcelona's grid infrastructure.
Our toughened glass undergoes a rigorous thermal tempering process. In the event of a failure, the glass shatters into small, non-conductive fragments (self-shattering), which makes it easy for maintenance teams to identify and replace "stub" units without a full line shutdown.
Yes, we offer factory-applied RTV (Room Temperature Vulcanization) Silicone coatings. This is specifically recommended for extreme industrial or maritime pollution zones to eliminate the need for manual washing.
