ABSTRACT:
An explosion-preventing suspension insulator includes an insulator body and a metal cap and a metal pin both being bonded to the insulator body by means of cement. A synthetic resin based electrical insulating film having a Young's modulus of elasticity of from 20,000 to 80,000 kgf/cm.sup.2 is provided in a specific thickness on the inner surface of the metal cap and the outer surface of the metal pin at a portion where the metal pin is buried into the cement. The preferred thickness of each electrical insulating film is from 600 to 1,500 .mu.m.
