Abstract
The utility model provides an insulating sleeve of an electric cable. The insulating sleeve comprises two layers, wherein the first layer is of a compound insulating sleeve umbrella skirt made of silicon rubber, the second layer is of an insulating sleeve inner wall made of glass fiber reinforced epoxy resin, and the second layer is arranged in the first layer. The insulating sleeve of the electric cable, provided by the utility model, solves the problems of low safety and poor pollution resistance of a porcelain sleeve; when the insulating sleeve is damaged in an accident, because a compound insulating sleeve constituted by the silicon rubber and a synthetic resin glass fiber cylinder has strong impact resistance and low possibility in explosion, the safety is higher; and the silicon rubber has the advantages of light weight, easiness in mounting, hydrophobicity and capability of relatively increasing creepage distance, as well as good pollution resistance and maintenance-free property.
Description
Technical field
The utility model relates to electric cable accessories, relates in particular to the insulating case of cable.
Background technology
High-tension cable adopts insulator as insulating case more.The anti-riot poor performance of this insulator when dielectric in the terminal takes place to puncture, presses sharply in the terminal to increase, and insulator is blasted.Because insulator belongs to fragile material, other electric equipments and personnel's safety around the fragment after the blast just inevitably brings disaster to, so its danger is higher.In addition, this porcelain system insulating case resistance to soiling is bad, accumulates dust easily, need power failure regularly to clean and safeguard, and weight is heavier, is difficult for installing.
The utility model content
In order to solve the problem of the shortcoming that the insulator fail safe is not high in the prior art, resistance to soiling is not strong, the utility model provides a kind of insulating case of cable.
The utility model provides a kind of insulating case of cable, comprise two-layer, the compound insulation sleeve full skirt of ground floor for processing by silicon rubber, the insulating case inwall of the second layer for processing by glass fiber reinforced epoxy resin, the second layer is arranged on the inside of said ground floor.
As the further improvement of the utility model, said compound insulation sleeve full skirt and said insulating case inwall design for integral type.
As the further improvement of the utility model, said compound insulation sleeve full skirt and said insulating case inwall are split-type design.
As the further improvement of the utility model, also comprise the 3rd layer, the 3rd layer is arranged on second layer inboard, and the 3rd layer is the liquid insulating medium layer of being made up of polyisobutene.
Further improvement as the utility model also comprises sealing shroud, and said sealing shroud is connected with said compound insulation sleeve full skirt through sealing ring.
As the further improvement of the utility model, also comprise ground connection cover and adhesive waterproof tape, said ground connection cover is connected with said sealing shroud, and said adhesive waterproof tape is arranged on the end of said ground connection cover.
The insulating case of a kind of cable of the utility model has solved the problem of the shortcoming that the insulator fail safe is not high, resistance to soiling is not strong; When accidental damage occurring; The compound insulating sleeve anti-impact force that is made up of silicon rubber and synthetic resin glass fiber packages is strong, and explosion potential is low, so its fail safe is higher; And silicon rubber is in light weight, is easy to install, and has hydrophobicity, has improved creepage distance relatively, and silicon rubber also has good resistance to soiling in addition, and is non-maintaining; Polyisobutene viscosity as dielectric is big, under the slight mechanical shock of wind, ground, can not caused the variation of electric parameter by the cable termination of its filling.
Sealing shroud and ground connection cover well link together with lower flange, through the sealing ring sealing, guarantee that insulating oil can well seal, and guarantee that also the outer semiconductive layer of cable can not be immersed in the insulating oil the inside.
Description of drawings
Fig. 1 is the insulating case of a kind of cable of the utility model and structural representation after cable is connected.
