Product Description

Product Introduction of 12kV Hollow Composite Insulator

The 12kV hollow composite insulator is a new-generation high-performance insulating component widely used in medium-voltage power systems. It is ideal for voltage transformers, capacitors, arresters, and switchgear. Compared with traditional porcelain insulators, it features lower weight, excellent anti-pollution performance, and high hydrophobicity, making it suitable for harsh environments.

Structure and Material

The 12kV hollow composite insulator is composed of three main parts: inner core tube (usually epoxy fiberglass), silicone rubber housing, and metallic end fittings.

• Core Tube: Made of epoxy resin reinforced with fiberglass, offering excellent mechanical strength and dielectric insulation.

• Housing: One-piece molded high-grade silicone rubber provides strong UV resistance, aging resistance, and hydrophobicity.

• End Fittings: Attached via crimping or bonding to ensure a secure and stable mechanical connection.

Technical Specifications

• Rated Voltage: 12kV

• Frequency: 50Hz

• Insulation Level: Lightning Impulse Withstand ≥75kV; Power Frequency Withstand ≥42kV

• Mechanical Compressive Strength: ≥80kN

• Creepage Distance: ≥360mm (customizable)

• Operating Temperature: -40ºC to +60ºC

• Material Standards: IEC 62231, GB/T 19519 compliant

Performance Features

1. Shock and Explosion Resistant: Composite design eliminates ceramic shattering risk and ensures high seismic resistance.

2. Excellent Hydrophobicity: Silicone rubber surface provides self-cleaning and anti-pollution characteristics.

3. Lightweight and Easy to Install: Weighs about half of traditional porcelain, reducing transport and installation costs.

4. Low Maintenance: Surface is less prone to contamination, requiring minimal cleaning-suitable for challenging environments.

5. Eco-Friendly Materials: Non-toxic and pollution-free, meeting modern environmental protection standards.

Application Scope

The 12kV hollow composite insulator is widely used in power insulation systems such as GIS, transformers, circuit breakers, capacitors, cable terminals, and surge arresters. It is particularly suitable for coastal, desert, polluted, and extreme weather regions.
