U120BP U160BSP Durable Anti Fog Insulators Chemical Corrosion Resistant Electrical Glass Insulator

Product Overview

Engineered to excel in aggressive environments, our Durable Anti-Fog Insulators Resistant to Salt Spray and Chemical Corrosion provide unwavering performance for critical substation infrastructure. These specially designed glass insulators withstand the dual threat of saline fog and chemical pollutants, effectively eliminating leakage currents and preventing flashovers in coastal and industrial zones.

Utilizing high-strength toughened glass construction, these anti-fog variants deliver exceptional resistance to surface degradation caused by salt spray, chemical corrosion, and humidity. The optimized fog-proof profile ensures rapid self-cleaning action, preventing contaminant buildup in heavy-fog regions, chemical processing areas, and salt-laden coastal environments.

Rated at 550kN mechanical load capacity, these durable insulators offer robust mechanical integrity alongside superior dielectric properties. Ideal for substations requiring long-term reliability against environmental stress, they ensure continuous power transmission with minimal maintenance requirements and extended operational lifespan.

Anti-fog glass insulator fabrication follows integrated precision workflows. Mineral components undergo automated weighing and batching before high-temperature melting at 1500+°C into uniform glass melt. Precision molds shape the extended-leakage anti-pollution profile in one controlled pressing operation.

Multi-stage annealing delivers stress-free glass bodies with long-term mechanical stability. Glass shells permanently bond with corrosion-protected fittings through expanding cement and polymer sealing systems. Comprehensive 100% inline testing—laser dimensional verification, mechanical load validation, and high-voltage dielectric assessment under simulated contamination—precedes traceability encoding and protective export packaging. This closed-loop process guarantees consistent flashover prevention in industrial zones with persistent airborne deposits.

Each insulator receives complete traceability encoding before protective export packaging. This closed-loop manufacturing process guarantees consistent flashover prevention, even in industrial zones with persistent airborne deposits.

Technical Specifications

01 Dual Manufacture Bases

Tailun adopts a dual‑base collaborative development pattern.

The Huzhou Headquarters covers a land area of 130 mu (83,609 square meters) with a building area of 74,800 square meters, undertaking R&D, forming & cementing production, quality inspection and comprehensive office functions.

The Anhui Base, with a site area of 34,600 square meters and building area of 14,700 square meters, serves as the large‑scale supporting production site.

Supported by the two bases, the company achieves an annual production capacity of 7.2 million pieces of toughened glass insulators, covering a full voltage range from 10 kV to 1100 kV. Our products are well‑suited for diversified application scenarios of power grid projects both at home and abroad.

02 Advanced Manufacturing

Backed by dual‑base manufacturing layout, Tailun manufactures high‑performance toughened glass insulator for global power‑grid projects. Our production workshop is equipped with world‑class imported facilities, including American Mettler‑Toledo batching‑weighing systems, Italian AMIGO thermal‑shock lines, glass pressing & toughening machines, and British glass melting furnaces. Combined with our self‑developed intelligent temperature‑controlled firing system, every toughened glass insulator gains optimized glass formula and uniform internal stress.

Advanced production processes make our insulator deliver 20% higher mechanical strength than industry standards, with self‑shatter rate controlled below 0.01%. Complete in‑house test apparatus supports full‑range performance verification for each insulator, covering mechanical failure load, thermal‑shock resistance, lightning impulse, zinc‑coating inspection and non‑destructive metal‑fitting detection. Every toughened glass insulator undergoes strict full‑item testing before delivery, ensuring stable long‑term service even in desert, plateau, coastal and other harsh working environments.

03 Key Features

04 Quality Assurance Process

Full-process inspection from raw material to finished.

Quality control is implemented throughout the manufacturing process, from raw material inspection to finished product inspection.

The manufacturing and testing process can be aligned with applicable IEC, GB and project-specific technical requirements.

05 Packing & Delivery

Toughened glass insulators are packed in solid export‑grade plywood wooden cases. Each insulator is individually protected with shock‑absorbing cushioning materials inside the crate to avoid collision, scratch and glass breakage during sea‑land multimodal transportation. Wooden cases are suitable for long‑distance overseas shipment, container loading and rough site handling. Marking including product model, quantity, weight and shipping marks is clearly printed on case surface to facilitate receiving and on‑site inventory check.

06 Typical Applications

In China, we serve as a core supplier to State Grid and China Southern Power Grid, covering more than 30 provinces and supporting major national projects including the West-to-East Power Transmission Project. Globally, we actively respond to the Belt and Road Initiative. Our products are exported to over 50 countries and regions across Southeast Asia, Europe, the Middle East, South America and Africa, and we take part in numerous overseas power infrastructure projects.

07 Certifications

The company has passed ISO9001, ISO14001 and ISO45001 management system certifications, and been awarded Top Ten Brands in China’s Glass Insulator Industry. All testing procedures comply with GB national standards and IEC international standards, backed by three professional laboratories equipped with full-range advanced testing instruments.
