Insulation Challenges in Industrial Zones
Industrial zones in the Middle East face sandstorms, salt spray corrosion, high temperatures (50°C+) and chemical pollution all year round, which makes traditional pin insulators prone to pollution accumulation, flashover, and threaten the stability of distribution systems. Saudi Arabia’s Jizan Industrial City will lose more than $1.2M due to insulation failures in 2022, and an efficient solution is urgently needed.
Solution: The core advantages of anti-pollution pin insulators
Anti-pollution ceramic pin insulators are designed specifically for the Middle East:
Petrochemical plants: Double-layer shed structure prevents oil and gas dust accumulation and reduces short-circuit risks.
Port machinery power supply: Salt spray protective coating resists corrosion from humid sea breeze and extends service life to 25 years+.
Desert solar power stations: UV-resistant ceramic glaze reduces electrostatic adsorption of sand and dust to ensure DC system efficiency.
Steel smelters: High-temperature sintered alumina materials withstand 80°C environments to avoid thermal expansion and cracking.
Industrial area transmission tower: Extended creepage distance design (≥320mm) to cope with dust + humidity combined pollution.
Technical parameters: Customized for harsh environments
Material: High-alumina porcelain (Al₂O₃≥95%), in line with IEC 60383 & BS 137 standards
Voltage level: 11kV-33kV (customizable 66kV)
Mechanical strength: ≥12kN (far exceeding the 8kN of ordinary ceramic pin insulators)
Key certification: IP68 dust and water resistance, 2000 hours of salt spray test without degradation
Customer case: Ras Al Khaimah Industrial Zone Upgrade Project in the UAE
In 2023, after replacing 1,200 anti-pollution insulators in the zone:
Flashover accidents decreased by 92%, and annual maintenance costs saved $280K
Anti-sand and dust performance increased by 3 times, adapting to level 7 strong wind environment
Customer feedback: “The anti-pollution design completely solved our power outage problem, and the power supply stability reached 99.6%.”
FAQ:
Q1: Compared with ordinary pin insulators, how long is the life of the anti-pollution type?
✅ Answer: High-density ceramic + anti-fouling coating extends the service life from 10 years to 25 years, and maintains 90% performance in dusty climates.
Q2: Is it suitable for old distribution systems?
✅ Answer: It supports standard ANSI/IEC sizes and provides a direct installation solution without modification. Replacement can be completed in 3 hours/tower.
Q3: How to deal with material embrittlement caused by extreme temperature differences?
✅ Answer: It adopts low-temperature sintering technology, and there is no crack in the thermal shock test from -30°C to 80°C, which has been verified by the Saudi Dammam project.
