Lightning protection needle insulator FEG-12 5

Composite lightning protection needle insulator is a special type of insulator that combines the functions of lightning protection and insulator.
This type of insulator is commonly used in overhead power lines. It can connect overhead insulated wires or bare wires to metal fittings on tension rods or corner rods, thereby tightening and insulating the overhead wires and providing lightning protection. The main feature of composite lightning protection needle insulators is the ability to form an air gap between the high and low voltage electrodes at the left and right ends of the insulator, which can provide lightning flashover channels and arc discharge channels. Its operating voltage is lower than that of the insulator body, so it can act before the insulator body flashover, causing lightning to drain and protecting the insulator and wire from lightning damage
