As the Netherlands undergoes a rapid transition toward carbon neutrality by 2050, the national grid operator TenneT is investing billions in reinforcing the 380kV and 220kV transmission networks. The Dutch climate—characterized by high humidity, salt-laden North Sea winds, and dense industrial clusters near Rotterdam and Amsterdam—demands superior insulation technology.
The Double-Shed Type Glass Insulator has emerged as the gold standard for these environments. Unlike standard profiles, the double-shed design increases the creepage distance without significantly extending the string length, providing critical protection against pollution flashover in saline and industrial fog conditions.
The evolution of Double-Shed technology is moving toward "Smart Insulation." Our R&D centers in Jiangxi are currently integrating RTV (Room Temperature Vulcanization) silicone coatings with toughened glass to provide a "permanent" hydrophobic surface. For Dutch utilities, this means a reduction in maintenance cycles and zero-requirement for manual cleaning in coastal wind farms.
Minimizing wind drag in high-velocity coastal corridors, essential for North Sea offshore integration.
Utilizing high-purity glass melt to ensure self-cleaning properties even under heavy Dutch drizzle.
Future insulators will support integrated sensors for real-time leakage current monitoring.
Located in the heart of China’s insulator manufacturing hub in Jiangxi, Jiangxi QOCI Electric Co. Ltd offers a unique advantage for Dutch suppliers. With a registered capital of 508 million Yuan and an annual output exceeding 39,000 tons, we provide the scale necessary for large-scale infrastructure projects.
Our vertical integration—from raw material processing to high-voltage testing—ensures that we are not affected by global logistics volatility. For Netherlands-based partners, this translates to 30% faster delivery times compared to European domestic manufacturers, combined with Tier-1 quality that meets all NEN and IEC standards.
Jiangxi QOCI Electric Co. Ltd was founded in Dec. 2002, with registered capital of 508 million Yuan. The Corporation is located at Industrial Park, Luxi County, Pingxiang, Jiangxi Province, covering area of 100 mu.
