The installed silicone umbrella skirt on the porcelain bottle can increase the pollution flashover voltage. Also, it can prevent the pollution flashover failure of the power transmission and transformation equipment. It is currently an effective anti-fouling measure for the external insulation of power transmission and transformation equipment.
The silicone umbrella skirt is applied to the insulator, and it is glued to the surface of the porcelain insulator umbrella bottle to change the characteristics and structural shape of the porcelain surface. It plays a positive role in the anti-pollution transformation of substation equipment.
(1) The silicone umbrella skirt has excellent material properties, and it has excellent hydrophobicity, anti-corona and anti-electric tracking. Also, it has no corrosion, no static electricity, and no dust.
(2) The silicone umbrella skirt has wide application and it is flexible to use. It is suitable for various porcelain parts of substation equipment, such as ordinary type, anti-pollution type pillar porcelain bottles, circuit breakers, instrument transformer andbushings. The number, position and shape of the silicone umbrella skirt can be determined according to the pollution level, pollution nature and equipment operating conditions on-site to obtain the best effect.
(3) There are no gaps between the well-constructed silicone umbrella skirt and the porcelain skirt, and the bonding strength is high with an integrated umbrella skirt.
(4) The silicone umbrella skirt has a reasonable structure and beautiful appearance, and the on-site construction and installation are simple and time-saving.
(5) The silicone umbrella skirt has low investment and high efficiency. The effect of the anti-fouling porcelain bottle can be obtained after the ordinary porcelain bottle is installed with a silicone umbrella skirt, which saves money. The anti-pollution porcelain bottles with a silicone umbrella skirt can effectively prevent the occurrence of pollution flashover accidents.
(6) The silicone umbrella skirt can reduce maintenance. In general, there is no need to clean the porcelain bottle that is installed with a silicone rubber umbrella skirt within 3-5 years.
