Product Description

36kV Composite Post Insulator High Voltage Line Support Insulator Overview

The 36kV composite post insulator is a modern high-voltage support insulator widely used in medium to high-voltage transmission and distribution systems. It functions to reliably isolate energized components from grounded structures while providing mechanical support to ensure system safety and stability.

Structure and Materials

This product is composed of three main parts:

• Core Rod: Made of high-insulation fiberglass-reinforced epoxy resin, offering both electrical insulation and mechanical strength.

• Silicone Rubber Housing: Delivers excellent hydrophobicity, anti-aging, and pollution flashover resistance, suitable for harsh environmental conditions.

• Metal Fittings: Forged hot-dip galvanized steel components provide secure mechanical connection and corrosion resistance.

Technical Specifications

• Rated Voltage: 36kV

• Power Frequency Withstand Voltage: 70kV (dry), 80kV (wet)

• Lightning Impulse Withstand Voltage: 170kV

• Bending Strength: ≥12.5kN

• Creepage Distance: ≥900mm

• Operating Temperature: -40ºC to +60ºC

• Pollution Class: Class IV

Performance Features

1. High Insulation Performance: Designed to meet 36kV system voltage requirements.

2. Robust and Reliable: One-piece molded design enhances mechanical strength and seismic resistance.

3. Long Service Life: Silicone rubber material resists UV, weathering, and aging for over 30 years.

4. Anti-Pollution Flashover: Excellent hydrophobicity reduces leakage and suits polluted environments.

5. Easy Installation: Lightweight structure reduces handling and maintenance costs.

Application Scope

This 36kV composite post insulator is ideal for urban power distribution networks, industrial facilities, substations, overhead cable terminations, and railway electrification. It performs well in high-humidity, high-pollution, and high-altitude environments.
