Leading the Southeast Asian Power Grid Revolution with Advanced Toughened Glass Insulation Technology & Information Gain Solutions.
Send Inquiry NowEngineered for high-voltage transmission lines in the Thai Eastern Economic Corridor (EEC).
Thailand's power landscape is undergoing a massive transformation under the Thailand Integrated Energy Plan (TIEP). As the Electricity Generating Authority of Thailand (EGAT) and the Provincial Electricity Authority (PEA) expand the 500kV and 230kV transmission networks, the demand for specialized insulators has surged. The Double-Shed Type glass insulator has emerged as the gold standard for Thailand’s unique tropical climate.
Information Gain: Why Double-Shed? Traditional insulators often fail in Thailand due to two primary factors: Heavy Salt Fog along the coastal regions (Chonburi, Rayong) and Industrial Solid Pollution in manufacturing hubs. The Double-Shed design (External Shed Profile) increases the leakage distance and creates an aerodynamic self-cleaning effect, significantly reducing the Risk of Flashover during the monsoon season.
Founded in 2002, Jiangxi QOCI Electric Co. Ltd stands as a titan in the electrical insulation industry. With a 70,000 m² state-of-the-art facility, we provide supply chain resilience that Thai EPC contractors rely on. In an era of global logistics volatility, our "Chinese Manufacture - Fast Delivery" model ensures that Thailand's grid projects remain on schedule.
Our Double-Shed Type production line utilizes a "Total Oxygen Kiln" process, ensuring the toughened glass maintains zero-defect structural integrity even under the extreme thermal cycles of the Thai summer.

Specifically designed for power lines running through the Gulf of Thailand, where salt accretion is a critical threat.
Providing 160kN to 300kN solutions for heavy industrial loads in the Pathum Thani and Ayutthaya provinces.
Our R&D focuses on the RTV (Room Temperature Vulcanization) Silicone Coating applied to toughened glass. This hybrid approach—combining the mechanical strength of glass with the hydrophobicity of silicone—is the ultimate technical roadmap for the Thailand 4.0 energy transition.

For the Thailand market, we strictly adhere to TISI (Thai Industrial Standards Institute) guidelines and International IEC 60305 standards. Every batch of Double-Shed insulators undergoes:
Heavy-duty solutions for the Thai Provincial Electricity Authority (PEA).
Toughened glass provides a unique "shatter-on-failure" characteristic that allows for easy visual inspection from the ground (no need for manual testing), which is crucial in Thailand's hard-to-reach jungle terrain.
Typically 15-25 days. Our Jiangxi factory is strategically located for rapid logistics via the China-Laos-Thailand railway and major ports like Laem Chabang.
Yes. The Double-Shed profile and RTV coating options are specifically engineered to maintain insulation resistance even at 95%+ relative humidity.
