Product Description
Porcelain suspension insulators are used on distribution and transmission lines.
Several pieces are connected together to provide electrical protection.
Composite long rod insulators can replace the porcelain suspension insulator strings, just keep the strength, creepage distance and section length the same, then they can provide same usage.
Standard: ANSI C29.2, IEC 60383, IEC60120
