Problems solved by technology

However, in order to increase the creepage distance, the existing rod-shaped insulators used for low-voltage transmission and transformation lines are provided with too many layers of ribs, which makes the cost too high and causes great waste after large-scale application
However, if the creepage distance is not enough, it will cause safety accidents such as line tripping, which is not conducive to the safe operation of low-voltage lines.

Abstract

The invention discloses a bar-shaped insulator used for a low-voltage circuit. The bar-shaped insulator comprises a bar-shaped insulator body and two metal caps which are respectively sleeved at two ends of the insulator, wherein a pair of ear flanges axially extend outwards from the outer end of each metal cap; a pair of through holes are formed in each pair of the ear flanges; two layers of umbrella edges of 25-29mm in space are formed in the middle of the insulator; and the diameters of the two layers of the umbrella edges are both 90-94mm. The bar-shaped insulator is relatively low in manufacturing cost and has sufficient creep distance, so that the bar-shaped insulator is applicable to large-scale application.

Description

technical field [0001] The invention relates to an insulator, in particular to a rod-shaped insulator used for low-voltage lines. Background technique [0002] Insulators are mainly used in high and low voltage transmission and transformation lines for insulation and support. At present, rod-shaped suspension insulators are widely used in low-voltage transmission and transformation lines, which have many advantages, such as: small size, light weight, long life, no need to detect zero value, and good self-cleaning performance. However, in order to increase the creepage distance, the existing rod-shaped insulators used for low-voltage transmission and transformation lines are provided with too many layers of ribs, which makes the cost too high and causes great waste after large-scale application. However, if the creepage distance is not enough, it will cause safety accidents such as line tripping, which is not conducive to the safe operation of low-voltage lines. Therefore, ...
