U70BLD U100BLD High Strength Glass Transformer Insulator Double Shed Glass Insulator
Product Overview
Our High Strength Double Shed Glass Insulator is engineered to deliver exceptional electrical insulation and mechanical resilience in demanding overhead power line applications. Featuring a robust two-shed design crafted from high-grade tempered glass, this insulator significantly extends creepage distance to effectively prevent flashovers and ensure stable power transmission even under extreme environmental stress.
Built for harsh operating conditions—including polluted atmospheres, heavy rainfall, and coastal climates—the double shed structure efficiently sheds water and resists contamination buildup, maintaining reliable performance over time. With superior resistance to weathering, electrical arcing, and thermal shock, this insulator offers long-term durability and minimal maintenance, making it an ideal choice for utilities and grid operators seeking to enhance the safety and reliability of their transmission infrastructure.
Choose our High Strength Double Shed Glass Insulator for a proven solution that combines advanced insulation technology with unmatched strength, supporting continuous and secure power delivery in the tough environments.

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
Designed to impact resistance, and structural stability ensure reliable performance under long-term tensile loads and harsh outdoor conditions.
Provides reliable electrical insulation and mechanical performance.
The transparent glass body makes it easier to identify visible damage during transmission line inspection.
Designed for long-term use in outdoor power transmission and electrical infrastructure.
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.
