产品详情
Wishpower 27.5kV rod suspension composite insulator is a railway-grade insulation component used in traction power supply systems, catenary suspension systems, cantilever structures and overhead railway lines. It combines excellent electrical insulation performance with stable mechanical strength and environmental resistance.
Main advantages include:
High-temperature vulcanized silicone rubber housing with excellent hydrophobicity and anti-pollution performance.
Epoxy fiberglass core rod for stable tensile strength and mechanical reliability.
Strong metal end fittings suitable for vibration and dynamic load conditions in railway systems.
Lightweight structure for easier transportation, installation and maintenance.
Suitable for coastal, polluted, humid, high-UV and harsh outdoor environments.
Core Features
High electrical insulation performance
The 27.5kV rod suspension composite insulator provides reliable insulation distance, power frequency withstand performance and impulse withstand capability for electrified railway systems.Excellent anti-pollution performance
The silicone rubber surface offers strong hydrophobicity and hydrophobicity transfer, helping reduce flashover risks in dusty, salty, humid and polluted environments.Stable mechanical strength
The fiberglass core rod provides high tensile strength and stable load-bearing performance under long-term railway catenary operation.Lightweight design
Compared with porcelain insulators, composite insulators are lighter, making installation easier and reducing the structural load on brackets and support systems.Aging and corrosion resistance
The silicone rubber housing has good resistance to UV, ozone, tracking, erosion and outdoor weathering.Easy installation and maintenance
The compact structure and customizable metal fittings allow the product to match different railway project requirements.
Product Structure
The 27.5kV rod suspension composite insulator usually consists of the following parts:
Fiberglass core rod
The main load-bearing component, providing mechanical tensile strength and structural support.Silicone rubber housing
The external insulation layer that protects the core rod and improves weather, moisture and pollution resistance.Insulating sheds
The shed profile increases creepage distance and improves operating safety in polluted environments.Metal end fittings
Usually made of hot-dip galvanized steel or customized metal materials, used for connection with catenary supports, suspension devices and line hardware.Sealing system
Reliable sealing between the housing and end fittings prevents moisture ingress and improves long-term service reliability.
