Engineered for high-humidity and saline-fog conditions in Samut Prakan and Bangkok areas.
Bangkok, the heart of Thailand's economic engine, faces unique electrical insulation challenges. As a major tropical metropolis situated near the Gulf of Thailand, the Bangkok Metropolitan Area (BMA) and its surrounding industrial provinces like Samut Prakan and Chonburi are subject to extreme humidity, high saline concentrations (Salt Fog), and heavy industrial particulate matter.
The Eastern Economic Corridor (EEC) expansion has led to a surge in demand for reliable 230kV and 500kV transmission lines. Our Anti-Pollution Type Toughened Glass Insulators are specifically designed to exceed the requirements of Thailand's Metropolitan Electricity Authority (MEA) and Provincial Electricity Authority (PEA) standards.
By utilizing advanced glass tempering techniques, our insulators offer superior mechanical strength and thermal stability, crucial for Bangkok's year-round tropical temperatures and monsoonal storms.
Global utility companies are shifting toward "Maintenance-Free" infrastructure. The "Information Gain" in our technical route lies in the Self-Cleaning Profile of our glass discs. Unlike porcelain, toughened glass allows for easy visual inspection, reducing maintenance O&M costs by up to 40% in high-pollution zones.
Founded in Dec. 2002, with a registered capital of 508 million Yuan, Jiangxi QOCI is a global powerhouse in insulator technology. Located in Luxi County, Jiangxi Province, our 100-mu facility serves as a world-class manufacturing hub for green energy construction.
Our mission is to serve the global power grid with dedication, participating actively in the construction of sustainable energy corridors from China to Bangkok and beyond.

Our insulators are classified by specialized aerodynamic profiles to combat specific environmental stressors.
Features leakage distances higher than IEC 60305. Designed with shallow ribs for effective self-cleaning by wind or rain. Ideal for inland regions surrounding Bangkok.
Characterized by long, widely-spaced under-ribs to avoid arc bridging. Ratio of 3.2 leakage distance/spacing. Perfect for coastal Bangkok and salt fog areas.
A high-tech solution for EHV lines. Room Temperature Vulcanization (RTV) silicone increases hydrophobicity, minimizing leaking currents in heavy industrial pollution.
As Bangkok transitions to a Smart Grid infrastructure, our research focuses on Intelligent Monitoring Insulators and Super-Hydrophobic Nano-Coatings. We are aligning our manufacturing with the "Bio-Circular-Green (BCG) Economy Model" of Thailand to ensure sustainable power distribution.

Toughened glass provides "Automatic Shattering" when faulty, making it easy for maintenance teams in Bangkok to identify failed units from the ground without expensive diagnostic equipment. Glass also has higher resistance to tropical heat aging.
Standard orders typically have a production lead time of 15-30 days, with an additional 5-7 days for shipping from our factory to major Thai ports, ensuring fast delivery for critical infrastructure projects.
Yes, our products are designed according to IEC 60305, IEC 60383, and ANSI C29 standards, which are the benchmarks for Thailand's Metropolitan Electricity Authority (MEA) and Provincial Electricity Authority (PEA).
Our Anti-Pollution and Anti-Fog profiles feature an increased leakage distance (creepage) and deep under-ribs that break the continuous film of saline water, preventing flashovers.
Accelerating the global energy transition with reliable power storage and transmission technologies.
How our technology withstands extreme icing, pollution, and typhoons across the Belt and Road regions.
