产品详情
The 20kV post composite insulator is widely used in medium-voltage power distribution systems for conductor support, electrical insulation and equipment mounting. Wishpower 20kV post composite insulator is designed with a silicone rubber housing and high-strength fiberglass core, making it suitable for outdoor distribution lines, substations and switchgear applications.
Main advantages include:
High-temperature vulcanized silicone rubber housing with excellent hydrophobicity.
Epoxy fiberglass core with strong bending and tensile strength.
Hot-dip galvanized or corrosion-resistant metal fittings for outdoor service.
Lightweight structure for easier transportation and installation.
Suitable for 20kV distribution lines, substations, switchgear and electrical equipment support.
Core Features
Reliable Electrical Insulation
The 20kV post composite insulator provides stable insulation performance in medium-voltage systems and helps reduce flashover and breakdown risks.Excellent Pollution Flashover Resistance
The silicone rubber surface maintains hydrophobicity, supporting reliable performance in dusty, humid and salt-fog environments.High Mechanical Strength
The fiberglass core offers strong bending and tensile performance for conductor support, busbar support and equipment mounting.Lightweight Design
Compared with porcelain insulators, composite insulators are easier to handle, transport and install.Weather and Aging Resistance
The product is suitable for long-term outdoor exposure, including UV radiation, rain, snow and temperature variation.Low Maintenance Cost
The anti-pollution surface helps reduce cleaning frequency and overall maintenance requirements.
Product Structure
The 20kV post composite insulator normally consists of the following components:
Silicone Rubber Sheds and Housing
Provides external insulation protection, increases creepage distance and improves pollution resistance.Epoxy Fiberglass Core
Serves as the main load-bearing component and ensures mechanical strength.Metal End Fittings
Used for connection with brackets, equipment bases, busbars or conductors. Common materials include hot-dip galvanized steel or customized corrosion-resistant fittings.Sealing Structure
Prevents moisture from entering the interface between the core and fittings.Integrated Manufacturing Process
Stable bonding and forming processes ensure reliable connection among the housing, core and fittings.
