GIS terminal new type tail tube
Technical field
The utility model relates to the electric cable accessories preparation field, relates in particular to a kind of GIS terminal new type tail tube.
Background technology
Tail pipe in the electric cable accessories, be used for HV cable accessories 500kV and following each electric pressure GIS terminal, the plug of dry type epoxy, branch joint etc., common tail pipe comprises matrix in the market, matrix is successively by a cylindrical section shape body, one section conical tube and a cylindrical section shape body identical with conical tube osculum end diameter are spliced, in order to be applicable to the different cross-sections of cable, the cylindric body of tail pipe end need to be made the specification of multiple different internal-and external diameters, and and little when large during the gap between the cable metal sheath, give subsequent installation, ward off lead-tight and bring larger trouble, the main following points of its defective: can't unify the encapsulation process method in the gap between the different cable metal sheaths when at first being installation, even the most skilled erector also off-centre can occur, the defective such as poorly sealed; Its two, description is many, and also needs welding between cone and the pipe, give to produce, stock control brings how inconvenience of storage, haves much room for improvement.
Summary of the invention
The utility model is for the deficiencies in the prior art, provide a kind of cost of manufacture little, make simple, the GIS terminal new type tail tube that installation accuracy is high.
The utility model is for solving the problems of the technologies described above, provide following technical scheme: GIS terminal new type tail tube, it is characterized in that comprising matrix, described matrix is spliced by a cylindrical section shape body and one section conical tube, and described conical tube osculum end is provided with some breach.
As further improvement of the utility model, described breach is strip.
The beneficial effects of the utility model: the utility model is by being provided with some breach at conical tube osculum end, expand by breach when making the osculum end be the docking of cable metal overcoat, can realize easily docking with the cable metal overcoat of different size, not only be beneficial to production and storehouse management, installation, be more conducive to assurance and the useful life of waterproof sealing effect, and with the tail pipe small end by the cylindric taper that makes into, saved production cost, be conducive to install and guarantee product quality.
