Product Overview
Wishpower 110kV post composite insulator is mainly used for mechanical support and electrical insulation in high voltage equipment. It is suitable for outdoor operation under harsh environmental conditions. Compared with traditional porcelain post insulators, composite post insulators offer lighter weight, better pollution resistance and stronger impact resistance.
Main advantages include:
High temperature vulcanized silicone rubber housing with excellent hydrophobicity.
High-strength epoxy fiberglass core rod for stable mechanical performance.
Reliable metal end fittings for equipment connection and structural support.
Lightweight design for easier transportation, handling and installation.
Suitable for substations, switchgear, capacitor banks, busbar supports and other high voltage applications.
Core Features
Excellent Pollution Flashover Resistance
The silicone rubber housing provides strong hydrophobicity and hydrophobicity transfer, reducing the risk of flashover in polluted environments.High Mechanical Strength
The fiberglass core rod provides strong bending, tensile and compression resistance for 110kV equipment support applications.Lightweight and Easy Installation
Compared with porcelain insulators, composite insulators are lighter and easier to transport, lift and install on site.Good Aging Resistance
The silicone rubber material offers excellent resistance to UV radiation, ozone, electrical erosion and tracking.Reliable Operating Performance
The compact structure and reliable sealing design help prevent moisture ingress and improve long-term service stability.Suitable for Harsh Environments
It can be used in high altitude areas, heavy pollution zones, coastal areas, humid regions and strong UV environments.
Product Structure
The 110kV post composite insulator usually consists of the following parts:
Silicone Rubber Housing
Provides external insulation, hydrophobicity, pollution resistance and weather resistance.Epoxy Fiberglass Core Rod
Works as the main load-bearing component and provides mechanical strength.Metal End Fittings
Usually made of hot-dip galvanized steel or customized metal materials for connection with brackets, busbars and electrical equipment.Sealing System
Reliable sealing at both ends helps prevent moisture, dust and contaminants from entering the interface.Shed Profile Design
The shed structure is designed according to voltage level and creepage distance requirements to improve external insulation performance.
