产品详情
Wishpower 69kV line post composite insulator is manufactured with a fiberglass reinforced core, silicone rubber housing and metal end fittings. It is suitable for 69kV overhead distribution and transmission lines where reliable insulation, mechanical support and long-term outdoor performance are required.
Compared with traditional porcelain insulators, composite insulators offer better handling convenience, lighter weight and stronger pollution resistance.
Main advantages include:
Lightweight structure for easier transportation and installation.
Silicone rubber housing with excellent hydrophobic performance.
High-strength fiberglass core for stable mechanical support.
Compact design to reduce maintenance pressure.
Customizable creepage distance, fittings and installation dimensions.
2. Key Features
Reliable Electrical Insulation
Designed for 69kV overhead power systems, the insulator provides stable insulation performance under long-term operating conditions.Excellent Pollution Flashover Resistance
The silicone rubber housing offers strong hydrophobicity, making it suitable for coastal, industrial, dusty and humid environments.High Mechanical Strength
The fiberglass core provides good bending strength, tensile strength and resistance to mechanical stress caused by conductor load, wind and vibration.Weather and UV Resistance
The polymer housing is resistant to ultraviolet radiation, ozone, moisture and outdoor aging.Easy Installation and Maintenance
The lightweight design helps reduce installation labor, lifting requirements and maintenance costs.Flexible Customization
Wishpower can customize the insulator according to project drawings, creepage distance, end fittings, color and electrical requirements.
3. Product Structure
The 69kV line post composite insulator mainly consists of the following components:
Fiberglass Core
The core is the main load-bearing part, providing mechanical strength and structural stability.Silicone Rubber Housing
The housing provides external insulation, hydrophobic performance and resistance to pollution, UV and aging.Metal End Fittings
Hot-dip galvanized steel or customized metal fittings are used for connection with crossarms, brackets or conductor support hardware.Sealing System
The sealing design prevents moisture from entering the interface between the core and fittings.Shed Profile
Proper shed spacing and shed design help increase creepage distance and improve insulation performance in wet and polluted environments.
