产品详情
Wishpower 35kV line post composite insulator is a polymer insulation product used on overhead power lines. It is commonly installed on poles, towers, crossarms or support structures to support conductors while maintaining the required insulation distance between live conductors and grounded components.
Compared with traditional porcelain or glass insulators, composite line post insulators offer a lighter structure, better anti-pollution performance and improved resistance to outdoor environmental stress.
Main advantages include:
Lightweight design for easier transportation and installation.
Silicone rubber housing with excellent hydrophobic performance.
High-strength epoxy fiberglass rod for stable mechanical support.
Hot-dip galvanized metal fittings for outdoor corrosion resistance.
Suitable for 35kV overhead lines, distribution networks and harsh operating environments.
Core Features
Excellent electrical insulation performance
The 35kV line post composite insulator provides reliable power frequency withstand and lightning impulse withstand performance for high-voltage line operation.Strong anti-pollution capability
Silicone rubber sheds help reduce pollution flashover risk in humid, coastal, industrial and contaminated environments.High mechanical strength
The fiberglass core provides strong bending and tensile performance, helping the insulator withstand conductor load, wind load and line vibration.Superior aging resistance
The silicone rubber housing offers resistance to UV radiation, ozone, temperature variation and electrical erosion.Easy installation and maintenance
The lightweight and compact structure reduces installation difficulty and improves maintenance efficiency.Reliable operating safety
The composite structure is not easy to break, reducing damage risks during transportation, installation and long-term operation.
Product Structure
A 35kV line post composite insulator usually consists of the following components:
Epoxy fiberglass core
The main load-bearing component that provides mechanical strength and structural stability.HTV silicone rubber sheds
Provide external insulation, increase creepage distance and improve anti-pollution performance.Silicone rubber housing
Protects the fiberglass core from moisture, contamination and UV exposure.Metal end fittings
Usually made of hot-dip galvanized steel or customized corrosion-resistant fittings for connection with crossarms, brackets or conductor clamps.Sealed interface area
Reliable sealing at the end fittings helps prevent moisture ingress and improves long-term operating reliability.
