High-Strength U420B Glass Suspension Insulators 420kN

Introduction to Glass Insulators

Glass insulators are critical components in overhead transmission lines, providing essential insulation and support for wires. Jiangxi Huayao Electric Co., Ltd., located in Shangbu Town Industrial Park, Luxi County, Pingxiang City, Jiangxi Province, China, is one of the leading glass insulator manufacturers in the country. With a registered capital of 120 million yuan and over 150 employees, the company is a major player in the glass insulator market.

Structural Composition and Features

The glass insulator consists of an iron cap, tempered glass parts, and steel feet, all integrated using cement adhesive. The product is designed with an advanced cylindrical head structure that offers:

• Small head size
• Lightweight
• High strength
• Large creepage distance

These features help in reducing metal usage and lower line costs. The traditional domestic structural shapes are utilized for the hat brim to accommodate live working needs.

Types of Glass Insulators

Jiangxi Huayao Electric Co., Ltd. produces various types of glass insulators, including:

• Standard type (40-550kN)
• Pollution-resistant type (70-400kN)
• Multi-umbrella type (120-330kN)
• Aerodynamic type (120-300kN)
• Ground wire type

Technical Specifications

The standard disk suspension type glass insulator IEC specifications include:

• Diameter D (mm)
• Spacing H (mm)
• Creepage Distance L(mm)
• Size of Coupling (mm)
• Mechanical Failing Load (kN)
• Power Frequency Withstand Voltage DRY (kV)
• Puncture Withstand Voltage (kV)
• Net Weight per Unit (kg)

Performance Advantages

Glass insulators offer numerous advantages, such as:

• Self-Breakage at Zero Value
• High Mechanical Strength
• Small Size and Weight
• Stable Electrical Performance

Inspection and Maintenance

The self-breaking characteristics of glass insulators allow for easy inspection, saving labor, material, and time costs. They also provide low maintenance costs due to their excellent anti-pollution flashover performance and hydrophobicity.
