Product Description

Product Introduction

The 33kV line post insulator is a high-performance electrical insulator specifically designed for medium-voltage transmission lines and substations. Made with composite materials, it offers excellent insulation properties and superior mechanical strength to ensure the safe and stable operation of power systems.

 

Structure and Materials

This insulator consists of three major parts: a high-strength fiberglass core, silicone rubber housing, and metal end fittings.

• Fiberglass Rod Core: Delivers high tensile and bending strength, serving as the central support structure.

• Silicone Rubber Sheath: Features excellent hydrophobicity, anti-pollution, UV resistance, and self-cleaning capability.

• Metal End Fittings: Made of hot-dip galvanized steel, corrosion-resistant, and suitable for various mounting options.

Technical Specifications (Typical Values)

• Rated Voltage: 33kV

• Power Frequency Withstand Voltage: 230kV

• Lightning Impulse Withstand Voltage: 170kV

• Mechanical Bending Load: ≥12kN

• Pollution Class: Level III or higher (customizable)

• Operating Temperature: -40ºC to +55ºC

• Service Life: ≥25 years

• Mounting Options: Flange/Thread (customizable)

Performance Features

1. Excellent Electrical Insulation: High dielectric strength, effective flashover prevention.

2. Superior Mechanical Performance: Supports high wind loads and tensioned conductor applications.

3. Strong Pollution Resistance: Silicone housing resists contamination and prevents flashovers in polluted environments.

4. Long Service Life: UV-resistant, anti-aging, and corrosion-resistant for extended usage.

5. Easy Installation and Maintenance: Lightweight and easy to transport, install, or replace.

Application Scope

The 33kV line post insulator is widely used in 33kV overhead transmission lines, distribution systems, substations, and urban power networks. It is particularly suitable for coastal areas, industrial zones, high-altitude, and heavily polluted environments. It can be vertically mounted on concrete poles or used with steel crossarms.
