Double umbrella glass insulator is the a kind of insulation equipment used for high-voltage transmission lines, the following will be from its structure, characteristics, applications and other aspects of a detailed introduction:
Double umbrella skirt design: The double umbrella glass insulator has two umbrella skirts of different sizes, one large and one small are arranged alternately. This design increases the creepage distance of the insulator, can effectively prevent the flashover phenomenon in the humid, dirty and other harsh environment, improve the insulation performance and anti-fouling ability of the insulator.
Connection structure: ball socket and ball head structure are generally used. This connection method has high mechanical strength and flexibility, can adapt to various stresses and deformations of transmission lines during operation, and is also convenient for installation and replacement of insulators.
