Product Description

Product Introduction

The Medium Voltage Fuse Cutout Composite Insulator is a critical component integrated with fuse cutout devices in power distribution systems. It provides mechanical support and electrical insulation while ensuring fault isolation under overcurrent or short circuit conditions. This insulator plays a vital role in maintaining grid safety and system stability.

Structure and Materials

This product is manufactured using advanced composite materials. The core rod is made from epoxy fiberglass, offering high tensile strength, while the outer housing features premium silicone rubber sheds for excellent hydrophobicity and UV resistance. End fittings are made from hot-dip galvanized or stainless steel for corrosion resistance and firm connection with fuse cutout structures.

Technical Specifications

• Rated Voltage: 12kV / 24kV / 33kV

• Maximum Operating Voltage: up to 36kV

• Tensile Strength: ≥10kN

• Dielectric Strength: Complies with IEC 61109

• Pollution Class: IV or customizable

• Number of Sheds: Depends on voltage level

• Service Life: ≥25 years

• Operating Temperature: -40ºC to +60ºC

Performance Features

1. Superior Insulation: Silicone rubber sheds provide excellent hydrophobicity and anti-tracking performance.

2. Compact and Lightweight: Lighter than porcelain insulators, easier for handling and installation.

3. Explosion-Prevention Design: Works with fuse cutouts to break the circuit quickly under fault conditions.

4. Harsh Environment Tolerance: Performs well in high altitude, polluted, or humid areas.

5. Long Lifespan & Low Maintenance: Designed for minimal maintenance during extended service life.

Application Scope

This insulator is widely used in 12kV to 36kV medium-voltage distribution networks, urban and rural grid upgrade projects, industrial and mining power systems, and renewable energy fields such as wind and solar farms. It is ideal for scenarios requiring fuse protection and insulation support.
