产品详情
Wishpower 66kV(72.5kV) post composite insulator is a high-voltage insulation support component used in transmission and substation systems. It is commonly installed on electrical equipment, busbar systems, disconnectors, surge arresters, instrument transformers and other power apparatus requiring reliable insulation and mechanical support.
Compared with traditional porcelain post insulators, composite post insulators are lighter, more impact-resistant and easier to install and maintain.
Key advantages include:
High-temperature vulcanized silicone rubber housing with excellent hydrophobic performance.
High-strength epoxy fiberglass core rod for stable mechanical support.
Hot-dip galvanized steel or customized metal end fittings for reliable connection.
Lightweight structure for easier transportation and installation.
Suitable for high altitude, heavy pollution, strong UV, humid and coastal environments.
Core Features
Excellent Electrical Insulation Performance
The 66kV(72.5kV) post composite insulator provides reliable power frequency withstand voltage, lightning impulse withstand voltage and surface insulation performance for high-voltage equipment.Superior Pollution Flashover Resistance
The silicone rubber housing offers strong hydrophobicity and hydrophobicity transfer, helping maintain insulation performance in dust, salt fog and humid conditions.High Mechanical Strength
The fiberglass core rod provides excellent bending strength and tensile strength, allowing the insulator to withstand mechanical loads, wind load and short-term impact.Lightweight Design
Compared with porcelain insulators, composite insulators are lighter and reduce structural load on equipment supports and mounting systems.Strong Aging and Weather Resistance
The silicone rubber outer layer resists UV radiation, ozone, temperature variation and electrical erosion, making it suitable for long-term outdoor operation.Lower Maintenance Cost
The product is not easy to break, reduces transportation damage and requires less frequent cleaning and maintenance.
Product Structure
The 66kV(72.5kV) post composite insulator generally consists of the following parts:
Silicone Rubber Housing
Provides external insulation, creepage distance, hydrophobic performance and environmental protection.Epoxy Fiberglass Core Rod
Works as the main load-bearing component and provides mechanical strength and structural stability.Metal End Fittings
Used for connection with electrical equipment, brackets or busbar systems. Materials may include hot-dip galvanized steel, stainless steel or customized metal fittings.Sealing Connection Area
Reliable crimping and sealing technology helps prevent moisture ingress into the core rod and fitting interface.Shed Profile
The shed design can be optimized according to pollution level, creepage distance and project requirements.
