Standard insulators often fail in Haifa or Ashdod due to saline accumulation. Our RTV-coated porcelain and glass solutions provide a hydrophobic surface that prevents leakage currents and flashovers in coastal industrial zones.
In the Negev, insulators face daytime temperatures exceeding 45°C and rapid nighttime cooling. Our high-grade ceramic alumina content ensures a low coefficient of thermal expansion, preventing internal stress fractures.
As Tel Aviv and Jerusalem expand, compact line post insulators (like the ANSI 57 series) are essential for space-constrained urban corridors, ensuring high voltage transmission with minimal visual and spatial footprint.
Founded in 2002 with a registered capital of 508 million Yuan, Jiangxi QOCI Electric Co. Ltd has established itself as a cornerstone of China's high-voltage insulation manufacturing industry. Our facility in Pingxiang, Jiangxi Province, covers 70,000 m² and operates with state-of-the-art Total Oxygen Kilns, ensuring the highest density and purity in our ceramic bodies.
For Israeli procurement officers, QOCI offers a unique combination of Supply Chain Resilience and Technical Compliance. We understand the stringent requirements of IEC 60305 and ANSI standards, ensuring that every unit shipped to Israel is tested for mechanical and electrical integrity under load.
Moving beyond standard silicone, we are developing nanostructured RTV (Room Temperature Vulcanization) coatings that offer superior self-cleaning properties, specifically targeting the fine silica dust found in the Israeli desert.
The roadmap includes insulators equipped with passive leakage current sensors, allowing Israeli grid operators to monitor insulator health in real-time without manual inspection, reducing maintenance O&M costs by 30%.
Supporting the 230kV transmission lines connecting Negev solar farms to the national backbone.
Providing corrosion-resistant insulation for power stations feeding Sorek and Ashkelon desalination units.
Supplying specialized porcelain insulators for Israel Railways (IR) 25kV AC overhead catenary systems.
Our dedicated logistics and technical teams ensure that every order reaches Haifa or Ashdod port with full documentation, including Type Test Reports from accredited international laboratories (KEMA, CESI, or equivalent).
While composite insulators are lightweight, the intense UV radiation in the Negev can lead to "tracking" and erosion of the polymer housing over time. High-quality porcelain is inorganic and completely immune to UV degradation, offering a service life of 40+ years in high-radiation environments.
We provide specialized "Anti-Pollution" or "Fog-Type" profiles with extended creepage distances. Additionally, our RTV silicone coating service for glass and porcelain insulators provides the hydrophobicity of a composite insulator with the mechanical strength of a traditional one.
Typical production for standard ANSI or IEC series is 4-6 weeks. Shipping from China to Haifa Port usually takes 25-30 days via sea freight. We also maintain a buffer stock of common components for urgent grid repairs.
Yes, we manufacture according to international standards (IEC, ANSI, BS) which serve as the foundation for the Israel Electric Corporation's technical specifications. We can provide customized testing to meet any specific local grid code requirements.
