Porcelain Pin Insulators
Pin Insulators,Simple. Strong. Trusted.
Pin insulators support or suspend wires and form electrical insulation between tower and wire — with sufficient insulation and mechanical strength for every load.
Porcelain Pin Insulators for Distribution Lines
A pin insulator supports or suspends a wire and forms electrical insulation between the tower and the wire. The pin-type porcelain insulator with cast steel fittings must withstand working voltage, overvoltage, and mechanical stress — with verified low-frequency flashover, impulse and RIV data.
Pin Insulator Series
55 series, 56 series and BS standard pin insulators with full electrical test data.
