产品详情
The Wishpower 66kV anti-wind deviation composite insulator is generally installed on transmission towers where conductor wind deviation may reduce electrical clearances. It provides both insulation and mechanical support, helping restrict lateral conductor movement during strong wind conditions.
Compared with traditional porcelain insulating components, the Wishpower composite design offers several advantages:
High-temperature vulcanized silicone rubber housing with excellent hydrophobic properties.
High-strength fiberglass-reinforced epoxy core rod for mechanical load transfer.
Lightweight construction for easier transportation and tower installation.
Reliable sealing between the housing, core rod and metal end fittings.
Customizable fittings for different tower structures and installation arrangements.
Suitable for coastal areas, mountain passes, valleys and open plains.
Improved resistance to pollution, moisture, ultraviolet radiation and corrosion.
The product helps reduce the possibility of conductor-to-tower flashover, line tripping and insulation failure caused by excessive conductor movement.
Core Features
Conductor Wind-Deviation Control
The structural arrangement limits lateral conductor movement and helps maintain the required electrical clearance under strong wind conditions.
Reliable Electrical Insulation
The silicone rubber housing provides stable external insulation performance in wet, polluted and salt-fog environments.
High Mechanical Strength
The fiberglass core rod withstands tensile, bending and dynamic loads generated by conductor movement and wind pressure.
Lightweight Construction
The composite design is lighter than comparable porcelain components, reducing transportation and high-altitude installation requirements.
Pollution and Weather Resistance
The insulator is suitable for industrial pollution, coastal salt fog, high humidity, ultraviolet exposure and substantial temperature variations.
Corrosion-Resistant End Fittings
Hot-dip galvanized steel, stainless steel or project-specified metal fittings can be selected according to the installation environment.
Custom Engineering Options
The overall length, creepage distance, mechanical rating, installation angle and end-fitting configuration can be adapted to project requirements.
Product Structure
A typical Wishpower 66kV anti-wind deviation composite insulator consists of the following components:
Fiberglass Core Rod
The fiberglass-reinforced epoxy core rod is the principal mechanical load-bearing and internal insulating component.
Silicone Rubber Housing and Sheds
The high-temperature vulcanized silicone rubber housing increases creepage distance and provides hydrophobic, weather-resistant external insulation.
Metal End Fittings
The end fittings connect the insulator to the tower, crossarm or conductor-side hardware. Ball-and-socket, clevis, eye, trunnion and customized fittings are available.
Crimped Connection Area
A controlled crimping process connects the core rod and metal fittings, allowing mechanical loads to be transferred safely.
Interface Sealing System
Sealing is provided around the fitting and housing interfaces to reduce the ingress of moisture, dust and corrosive contaminants.
Grading and Arc-Protection Accessories
Grading rings, arcing horns or other protective accessories may be installed according to electric-field and insulation-coordination requirements.
