Product Description

Product Introduction:

The Glass Insulator is an innovative electrical insulation element widely utilized in power transmission and distribution lines. This insulator evolves from traditional ceramic insulators by enhancing the manufacturing process and incorporating materials such as glass fiber reinforced plastic and silicate porcelain, resulting in a new generation of insulators with superior insulation and anti-fouling capabilities.

Product Details:

Material: Constructed with a combination of glass fiber reinforced plastic and silicate porcelain, offering a blend of strength and electrical insulation.
Design: Features a modern design that incorporates a metal cap, reinforced plastic rod, silicate inner core, rubber cover, and a sturdy base.
Key Features:

Enhanced Insulation: Offers excellent insulation performance with low dielectric constant and dielectric loss, making it suitable for high voltage lines and special environmental conditions.
Anti-Fouling Ability: Exhibits superior resistance to contamination, ensuring equipment operates normally in high-pollution areas and requires minimal maintenance.
Wind and Seismic Resistance: Demonstrates robust wind vibration resistance and seismic performance, capable of withstanding significant wind pressures and shocks, suitable for diverse harsh climates.
Structural Components:

Top Metal Cap: Provides a secure attachment point for conductors and equipment.
Glass Fiber Reinforced Plastic Rod: Contributes to the overall strength and flexibility of the insulator.
Silicate Inner Core: Serves as the heart of the insulator, offering strong mechanical support and insulation properties.
Rubber Cover: Protects the insulator from environmental factors and enhances its anti-fouling characteristics.
Base: Offers a stable and secure foundation for the insulator, ensuring reliable installation.
Performance Highlights:

Low Dielectric Constant and Loss: The insulator’s material composition ensures low dielectric constant and loss factors, critical for high voltage applications.
Long-Term Reliability in Pollution: The design allows for extended use in polluted environments without compromising performance.
Easy Maintenance: The insulator’s structure facilitates easy cleaning and maintenance, reducing downtime and operational costs.
Environmental and Operational Suitability:

Wide Temperature Range: Capable of operating across a broad temperature spectrum, typically from -50°C to +100°C, accommodating various climatic conditions.
UV and Weather Resistance: The materials used are resistant to UV radiation and can withstand various weather conditions without degradation.
Chemical and Corrosion Resistance: Engineered to resist common environmental chemicals and corrosive substances, preserving the insulator’s integrity.

Product Advantages
(1) High mechanical strength, 1 to 2 times higher than the mechanical strength of porcelain insulators.
(2) The performance is stable and not easy to age, and the electrical performance is higher than that of porcelain insulator.
(3) Fewer production processes, short production cycle, easy to mechanized, automated production, high production efficiency
(4) Due to the transparency of glass insulators, it is easy to find small cracks and various internal defects or damage during external inspection.
(5) When the glass body of the insulator has various defects, the glass will automatically break, which is called “self-breaking”. After the insulator is broken, the iron cap residual hammer still maintains a certain mechanical strength suspended on the line, the line is still
(6) It can continue to operate. When line inspectors patrol the line, it is easy to find self-broken insulators, and timely replacement of new insulators. Because the glass insulator has this “self-breaking” characteristic, it is online
(7) In the process of road operation, it is not necessary to carry out preventive test on the insulator, which brings great convenience to the operation.
(8) Light weight of glass insulators. Due to the manufacturing process and other reasons, the “self-breaking” rate of glass insulators is high, which is the fatal shortcoming of glass insulators.

Application Places
Glass disc suspension insulators are widely used in various electrical power systems. They are designed to support the weight of conductors and provide insulation between the conductors and the supporting structures, such as towers or poles.
Overhead Transmission Lines: These insulators are used to support conductors and provide insulation in overhead transmission lines, ensuring reliable power transfer over long distances.
Substations: They are employed in substations to insulate busbars, support equipment, and maintain proper electrical isolation between different components.
Distribution Lines: Used in distribution lines to insulate and support power lines that deliver electricity to consumers.
