When the insulator is used, the single insulator is connected between the conducting wire and the tower through the hardware fitting to play a role in insulating and supporting the conducting wire, the insulator is mainly formed by cementing parts such as a porcelain piece, an iron cap, a steel foot and the like through cement adhesive, and the insulator structurally can be divided into a head part and an umbrella skirt. The insulator bears the comprehensive effects of tension, vibration, system voltage, various filth and impact overvoltage during operation, and can be kept to work all year round without damage under the environment, so that the insulator is required to have higher mechanical strength and certain internal and external electrical insulation levels and the like.

When insulator design is carried out, according to the intensity dispersibility characteristics of porcelain spare, the steel foot, the iron hat, it is simpler to select the shape, the intensity of whole insulator is controlled to the steel foot that intensity is controlled most easily, make the steel foot destroy earlier before iron hat and porcelain spare are destroyed, most insulators are the destruction of steel foot when destroying promptly, that is to say the intensity of steel foot is the intensity of insulator, but because the insulator receives the wind-force influence in the air often to produce in the insulator in the use and rock, the rocking of insulator just can cause the wearing and tearing of steel foot and fitting pin, thereby the intensity of insulator has been reduced, secondly the surface compressive stress of insulator is lower, greatly reduced porcelain nature destruction intensity.
