Product Description
A butterfly insulator is an insulating support that typically consists of two symmetrical housings, a helical locking cap, and a rubber gasket. It is primarily used in low-voltage distribution systems, such as indoor switchboards and outdoor switchgear. Compared with pin-type insulators, butterfly insulators are easier and more convenient to install, pose a lower risk of safety hazards, and are relatively inexpensive.
