Spindle For Insulator is a slender rod or pin used in insulators as a anchor point to connect the insulators with electrical wires or cables. The Insulator Spindle is an important part of the ceramic Pin Insulator Spindle, which determines the mechanical strength of the Insulator Long Shank Spindle. Its purpose is to fix the insulator on overhead transmission lines or substations, and can use strain clamps, U-bolts, plates and various accessories.
