The 35kV pin-hole HDPE insulator is a high-performance electrical insulating component designed for medium and high-voltage power transmission systems. It is extensively used in substations, distribution lines, and utility infrastructure. Made of high-density polyethylene (HDPE), this insulator features a sealed pin-hole structure that effectively prevents ingress of moisture and contaminants, enhancing its overall insulation reliability.
The insulator consists of injection-molded HDPE material with an internal steel core for mechanical strength. The outer surface is UV-resistant and anti-aging. HDPE offers excellent insulation performance, weather resistance, and mechanical durability, making it suitable for long-term outdoor applications under harsh conditions.
