The Composite HDPE Line Post Insulator is a high-performance electrical insulator designed for overhead distribution lines. Combining the advantages of HDPE housing and composite core materials, it is widely used in urban power grids, rural electrification projects, and electrified railway systems. This product delivers exceptional insulation, pollution resistance, and mechanical strength, making it a reliable alternative to traditional porcelain insulators.
This insulator consists of three key components: an HDPE housing, a fiberglass core rod, and galvanized steel fittings.
HDPE Housing: Offers superior hydrophobicity, UV resistance, and anti-pollution flashover performance.
Fiberglass Reinforced Epoxy Rod: Ensures high tensile and bending strength.
Galvanized End Fittings: Provide secure mechanical connections and corrosion resistance.

High Pollution Resistance: HDPE sheds provide strong anti-pollution capabilities and self-cleaning behavior.
Stable Insulation: Composite structure offers superior dielectric performance with low breakdown risk.
Lightweight & Easy Installation: 50% lighter than porcelain, easier for field work.
Excellent Mechanical Strength: Core rod ensures robust support under mechanical loads.
Weather Resistance: Designed for outdoor use with long service life and minimal degradation.
Composite HDPE Line Post Insulators are suitable for medium-voltage distribution lines, railway catenary systems, renewable energy stations (wind & solar), and coastal or industrial areas with harsh environmental conditions such as heavy pollution or high salinity.
We provide comprehensive customization for voltage ratings, connection fittings, installation types, and creepage distances. OEM and ODM orders are welcomed, and we can manufacture according to customer drawings and technical specs to meet project-specific requirements.
