产品详情
Wishpower 220kV(252kV) composite post insulator is a high voltage insulating support product for 220kV power systems with a maximum system voltage of 252kV. Compared with traditional porcelain post insulators, composite post insulators offer lighter weight, better pollution flashover resistance and stronger seismic performance, making them suitable for modern substations and power equipment upgrades.
Main product advantages include:
High temperature vulcanized silicone rubber housing with excellent hydrophobicity and hydrophobicity transfer.
Epoxy fiberglass core rod with high bending strength and stable mechanical performance.
Reliable metal end fittings for long-term outdoor operation.
Lightweight structure for easier transportation, lifting and installation.
Suitable for high altitude, strong UV, heavy pollution, coastal salt fog and complex outdoor environments.
Core Features
Excellent Pollution Flashover Resistance
The silicone rubber housing provides strong hydrophobic performance, reducing the risk of conductive film formation on polluted surfaces.High Mechanical Strength
The fiberglass core rod provides high bending and tensile strength for 220kV substation equipment support.Lightweight and Easy Installation
Compared with porcelain insulators, composite post insulators are lighter and easier to transport, lift and install.Good Seismic and Impact Resistance
The composite material structure offers better flexibility and toughness for earthquake-prone areas and outdoor high voltage equipment.Strong Aging Resistance
The housing material provides good resistance to UV radiation, tracking, erosion and weathering.Lower Maintenance Cost
The surface has good self-cleaning performance, reducing cleaning frequency and long-term maintenance cost.
Product Structure
The 220kV(252kV) composite post insulator generally consists of the following components:
Silicone Rubber Sheds
The external insulation layer provides creepage distance and weather protection with excellent hydrophobicity.Epoxy Fiberglass Core Rod
The core rod carries the main mechanical load and provides bending, tensile and structural support strength.End Fittings
Usually made of hot-dip galvanized steel or customized metal materials for equipment connection and installation.Sealing System
The end sealing structure prevents moisture ingress into the core rod and fitting interface.Integrated Housing Structure
Injection molding or compression molding improves the bonding strength between the housing and core rod.
