Introduction

Porcelain spool insulator is an insulator of generally cylindrical form having an axial mounting hole and circumferential groove or grooves for the attachment of a conductor. Porcelain spool insulator usually used America consisting of one or more insulating parts to which connecting devices (metal fittings) are often permanently attached. Porcelain spool insulator or spool type insulator usually used similarly to shackle insulator.
