Abstract
The utility model discloses a composite insulator with a double-layers sheath, which relates to the field of power equipment and comprises a mandril and the sheath, wherein the sheath consists of an inner protective layer and an outer sheath; the inner protective layer wraps the surface of the mandril; the outer sheath wraps the surface of the inner protective layer and is provided with a plurality of round umbrella skirts with same size; an adhesion boundary layer is arranged between the mandril and the inner protective layer, and a melting boundary layer is arranged between the inner protective layer and the outer sheath; the inner protective layer and the outer sheath as well as the umbrella skirt are made of two kinds of silicon rubber materials with different formulas; and the thickness of the inner protective layer is equal to or more than 3mm, and the thickness of the outer sheath is equal to or more than 2mm. The composite insulator has the beneficial effects that as the outer sheath and the inner protective layer are made of different silicon rubber, the outer sheath and the inner protective layer have different functions on the insulating performance of the insulator; and the outer sheath can ensure that the insulator does not generate pollution flashover or wet flashover under overcast and rainy or foggy and moist weather conditions for a long time, and the inner protective layer can protect the mandril from being subjected to tracking damage due to electric leakage. The composite insulator is good in insulating property, simple and practicable in production technology, and convenient to popularize and apply.
Description
Technical field
The utility model relates to field of electrical equipment, is specifically related to a kind of double braid covering synthetic insulator.
Background technology
In the electronic defeated engineering of urban and rural power grids reconstruction project and west, need a large amount of insulators, however insulator of the prior art, poor, the anti-creepage trace poor performance of insulation property, the easy generation in existing along shortcomings such as bonding interface insulation breakdowns.
The utility model content
Technical problem to be solved in the utility model is to provide the double braid covering synthetic insulator that a kind of good insulation preformance, production technology are simple, be convenient to promote the use of.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of double braid covering synthetic insulator, comprise plug and sheath, it is characterized in that, sheath is made up of sheath and oversheath, sheath is wrapped in the surface of plug, and oversheath is wrapped in the surface of sheath, and oversheath is provided with the alternate circular full skirt of a plurality of sizes, the adhesive interface layer is arranged between plug and the sheath, the melting interface layer is arranged between sheath and the oversheath.
Described sheath is to be made by two kinds of different silastic materials of prescription with oversheath, full skirt.
Described sheath is to extrude by rubber silicon rubber is wrapped in mandrel surface, and oversheath, full skirt are to be integrally formed in the sheath surface by stage injection technology.
The thickness of described sheath is equal to or greater than 3mm, and the thickness of oversheath is equal to or greater than 2mm.
The beneficial effects of the utility model are: because oversheath is to adopt different silicon rubber to make with sheath; they have different effects to the insulation property of insulator; oversheath can guarantee that insulator is under the weather conditions that overcast and rainy, dense fog is moist for a long time; pollution flashover and wet the sudden strain of a muscle are not taken place; sheath can protect plug not damaged by creepage trace, and the utility model good insulation preformance, production technology be simple, be convenient to promote the use of.
