产品详情
Wishpower 220kV post composite insulator is an insulating and supporting component used in high voltage power systems. It is suitable for 220kV substations, switchgear, busbar supports, capacitor banks, reactors and other electrical equipment. Compared with traditional porcelain post insulators, composite post insulators offer lighter weight, better seismic performance, stronger pollution resistance and easier installation.
The product is manufactured with a high-strength epoxy fiberglass core rod, high temperature vulcanized silicone rubber housing and hot-dip galvanized metal end fittings. It can maintain reliable electrical insulation performance in high altitude areas, polluted zones, coastal environments, humid climates and strong UV conditions.
Key advantages of Wishpower composite insulators include:
Lightweight design for easier transportation, installation and maintenance.
Silicone rubber housing with excellent hydrophobicity and hydrophobicity transfer.
High-strength fiberglass rod for stable mechanical support.
Suitable for long-term outdoor operation with good UV and aging resistance.
Customizable creepage distance, metal fittings and installation dimensions.
Core Features
High Electrical Insulation Performance
The 220kV post composite insulator effectively separates live conductors from grounded structures and helps ensure safe operation of high voltage equipment.Excellent Pollution Flashover Resistance
The silicone rubber housing provides strong hydrophobic performance, reducing flashover risks in polluted, humid, coastal and industrial environments.Stable Mechanical Strength
The fiberglass core rod offers excellent bending, compression and tensile performance for supporting high voltage busbars and equipment loads.Lightweight Structure
Compared with porcelain insulators, composite post insulators are much lighter, helping reduce transport costs and installation difficulty.Good Seismic Performance
The composite structure provides better flexibility and impact resistance, making it suitable for seismic areas and complex outdoor applications.Low Maintenance Cost
The surface is not easy to accumulate pollution, which helps extend the maintenance cycle and improve power system operating efficiency.
Product Structure
The 220kV post composite insulator generally consists of the following parts:
Fiberglass Core Rod
The main load-bearing component, providing mechanical strength and structural stability.Silicone Rubber Housing
Made of high temperature vulcanized silicone rubber with excellent insulation, weather resistance and hydrophobicity.Shed Profile
The optimized shed design increases creepage distance and improves insulation performance under polluted conditions.Metal End Fittings
Usually made of hot-dip galvanized steel or stainless steel for connection with brackets, equipment bases or busbar structures.Sealing Area
Reliable end sealing helps prevent moisture ingress and improves long-term operating reliability.
Wishpower 220kV post composite insulator is suitable for insulation and mechanical support in high voltage substations and transmission systems. With lightweight design, high mechanical strength, pollution resistance, aging resistance and easy installation, it is widely used in 220kV power projects, wind power booster stations, solar power booster stations, coastal areas and industrial pollution zones. Wishpower can provide both standard products and customized high voltage insulation solutions for power grid projects.
