The 25kV pinhole HDPE insulator is a high-performance electrical insulation product made from high-density polyethylene (HDPE), commonly used in power systems for cable terminations and junction insulation. Its unique pinhole design enhances surface leakage distance and reduces flashover risk, ensuring safe and reliable electrical operation.
This insulator mainly consists of:
Main Body: Constructed from HDPE, which provides excellent electrical insulation and weather resistance.
Pinhole Design: Extends creepage distance and controls corona discharge.
Metal Fittings: Made of galvanized steel or aluminum alloy to ensure mechanical strength and durability.
HDPE offers advantages such as lightweight, corrosion resistance, and UV stability, making it ideal for outdoor electrical applications.
