At low temperatures and in areas with strong freeze-thaw cycles, HDPE insulator work better. The material is also inherently hydrophobic, so that these insulators “clean themselves” when it rains. HDPE Insulator is perfect for coastal areas and high pollutant locations where salt and chemicals can lead to persecution and early failure.
One example of many models
HDPE Insulator are molded from a proprietary blend of
gray, track and UV resistant, high density polyethylene. They are
more durable and reliable than traditional wet-process porcelain
insulators. They are also lighter, safer and easier to handle.
It is designed with standard ANSI neck and thread size.
It is a direct replacement for medium-voltage porcelain C-neck
insulators and recommended for all conductor types, bare or
covered.
• Exceeds ANSI electrical and mechanical requirements
• Resistant to impact damage, breakage and vandalism
• Designed for use with all Tie Products
• RUS Accepted
• Made in USA
