Abstract
The utility model relates to a high-voltage cable in an electric system, and specifically relates to a cable-type column switch cable silica gel umbrella skirt. The umbrella skirt is characterized by comprising an insulating sleeve and at least two umbrella-shaped gel umbrella skirts with center holes. The umbrella-shaped gel umbrella skirts sleeves the insulating sleeve at an equal interval. When the silica gel umbrella skirt is used, the sleeve is integrally connected with a cable wiring end by a special adhesive, so that a composite external insulation structure is formed. By excellent hydrophobicity and hydrophobic mobility property of silicone rubber, creep distance of the cable is improved, and meanwhile the pollution flashover phenomenon caused by cable salinization is prevented. The silica gel umbrella skirt is advantaged by compact structure, convenient installation, low cost, and high economic benefits and social benefits.
Description
Technical field
The utility model relates to the high-tension cable in electric power system, specifically a kind of improvement cable-type on-pole switch cable silica gel full skirt that top layer is insulated not enough in filthy situation.
Background technology
In actual installation use procedure, be located in due to coastal that there was dampness in the air and salinity weight, there is stronger corrosivity, and the performance difference to some extent of the switching cable of different manufacturers supply, cause the cable-type demarcation switch that is partly arranged on coastal area because of the aging capping salt segregation junction of cable mid portion and surface insulation deficiency, have application risk.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, propose a kind of cable-type on-pole switch cable silica gel full skirt of being arranged on coastal area, having higher dielectric strength and pollution flashover voltage under dirty wet condition of being applicable to.
The present invention can reach by following measure:
A kind of cable-type on-pole switch cable silica gel full skirt, it is held to levy and is to be provided with insulating sleeve and at least two umbrella silica gel full skirts with centre bore, and umbrella silica gel full skirt is socketed on insulating sleeve equally spacedly.
Umbrella silica gel full skirt described in the utility model is the thin shape in central thick outer, and outer wall is taper, and inwall is arcuation, for improve creepage distance.
When the utility model uses, by special bonding agent, sleeve is connected with cable termination, form combined type external insulation structure, utilize hydrophobicity and the migration of hydrophobicity of silicon rubber excellence, increase the creepage distance of cable, prevent the pollution flashover phenomenon that cable salinization causes simultaneously, there is compact conformation, easy for installation, with low cost, economic benefit and social benefit advantages of higher.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in the figure: a kind of cable-type on-pole switch cable silica gel full skirt, it is held to levy and is to be provided with insulating sleeve 1 and at least two umbrella silica gel full skirts 2 with centre bore, umbrella silica gel full skirt 2 is socketed on insulating sleeve 1 equally spacedly, umbrella silica gel full skirt 2 described in the utility model is the thin shape in central thick outer, outer wall is taper, inwall is arcuation, to improve creepage distance, when the utility model uses, by special bonding agent, sleeve is connected with cable termination, form combined type external insulation structure, utilize hydrophobicity and the migration of hydrophobicity of silicon rubber excellence, increase the creepage distance of cable, prevent the pollution flashover phenomenon that cable salinization causes simultaneously, there is compact conformation, easy for installation, with low cost, economic benefit and social benefit advantages of higher.For this cable silica gel full skirt.It is raw material that this silica gel full skirt uses silicon rubber, is processed into umbrella skirt construction, utilizes the hydrophobicity of silicon rubber and the characteristic of umbrella skirt construction increase creepage distance to make.When use, only need smear adhesive special at this silica gel full skirt inwall, and be inserted in the terminals of cable, after binding agent comes into force completely by the time.
