Abstract
The invention discloses a conical composite insulator, comprising a central body, a jacket wrapped outside the central body, and an umbrella skirt arranged outside the jacket. The central body comprises a large-diameter part and a small-diameter part. The umbrella skirt comprises at least one first umbrella skirt set arranged on the large-diameter part and at least one second umbrella skirt set arranged on the small-diameter part. The skirt length of the umbrella body of the first umbrella skirt set is less than that of the corresponding umbrella body of the second umbrella skirt set. The skirt length of each umbrella body of the first umbrella skirt set arranged on the large-diameter part of the conical composite insulator is less than that of each umbrella body of the second umbrella skirt set arranged on the small-diameter part. Because the diameter of the section of the small-diameter part is less than that of the large-diameter part, the material increase resulted from the increase of the skirt length of each umbrella body of the second umbrella skirt set is less than the material saving quantity resulted from decrease of the skirt length of each umbrella body of the first umbrella skirt set; and therefore, the material utilization amount is reduced, and the cost is reduced.
