Description
Technical field
The utility model relates to a kind of composite sheath terminal tail pipe, is specifically related to a kind of novel 110kV and above composite sheath terminal tail pipe, is applicable to 110kV and above cross-linked polyethylene insulated cable composite sheath terminal.
Background technology
110kV and above cross-linked polyethylene insulated cable composite sheath terminal tail pipe and electrical cable aluminium sheath all adopt sealing lead technique, and sealing lead plays sealing respectively and is electrically connected these two effects.Need high-temperature heating aluminium sheath during sealing lead, heating causes cable body to there is the possibility damaged; Lead is high potential metal in addition, and easy and aluminium generation electrochemical reaction, causes sealing lead to get loose, and sealing and electrical connection performance can not get effective guarantee.Because sealing lead technique exists above-mentioned shortcoming, therefore need a kind of tail pipe of non-sealing lead structure.
Summary of the invention
The purpose of this utility model is the defect adopting sealing lead technique to exist for cross-linked polyethylene insulated cable composite sheath terminal tail pipe and electrical cable aluminium sheath, a kind of 110kV and above cross-linked polyethylene insulated cable composite sheath terminal tail pipe are provided, without the need to sealing lead when adopting this tail pipe to install, adopt copper mesh can realize aluminium sheath and be connected with the reliable of tail pipe.
The purpose of this utility model is achieved through the following technical solutions:
A kind of novel 110kV and above composite sheath terminal tail pipe, comprise tail pipe body, be provided with inner terminal at described tail pipe body upper part inwall and fix ear, external wall of upper portion is provided with external terminal and fixes ear; Be equipped with multiple capillary groove at described tail pipe body lower end inner wall, be provided with hot melt adhesive layer at the corresponding capillary groove of tail pipe body lower end inner wall.
Described tail pipe body is inner conical body, and the truncated cone-shaped body of the cylindrical body comprising two sections of different-diameters and the cylindrical body connecting two sections of different-diameters, described tail pipe body is one-shot forming.
The number that described inner terminal fixes ear is 2, and symmetry is arranged on tail pipe body upper part inwall; It is 2 that described external terminal fixes ear number, and symmetry is arranged on tail pipe body upper part outer wall.
Described capillary groove is preferably 3.
Advantage of the present utility model:
1, the utility model tail pipe structure is simple, and simple to operate, during installation, electrical cable aluminium sheath and composite sheath terminal tail pipe are without the need to sealing lead, adopts tin-coated copper braiding earth connection to connect, high relative to sealing lead reliability, effective guarantee electrical connection performance;
2, the utility model tail pipe lower end inner wall is provided with capillary groove, improves water proofing property, adds bonding fastness when tail pipe and cable PUR bond simultaneously; During installation, after tail pipe lower port inwall and cable adopt PUR to bond, outside is provided with water blocking tape lapping layer, glass fibre epoxy armour, pyrocondensation tube layer, has good waterproof performance, intensity is high, weatherability is good advantage.

Embodiment
By reference to the accompanying drawings and embodiment, the technical solution of the utility model is described further.
As shown in Figure 1, a kind of novel 110kV and above composite sheath terminal tail pipe, comprise tail pipe body 1, be provided with 2 inner terminals symmetrically in described tail pipe body 1 upper inside wall and fix ear 2, correspond to inner terminal in tail pipe body 1 external wall of upper portion and fix ear 2 and be provided with external terminal and fix ear 3; Be equipped with 3 capillary grooves 4 at described tail pipe body 1 lower end inner wall, be provided with hot melt adhesive layer 5 at the corresponding capillary groove 4 of tail pipe body 1 lower end inner wall.
Described tail pipe body 1 is inner conical body, and the truncated cone-shaped body of the cylindrical body comprising two sections of different-diameters and the cylindrical body connecting two sections of different-diameters, described tail pipe body is one-shot forming.
As shown in Figure 2, when the present embodiment composite sheath terminal tail pipe and electrical cable aluminium sheath are installed, external terminal extenal fixation ear 3 dead earth line; One end of tin-coated copper braiding earth connection 7 is connected with electrical cable aluminium sheath 6, and wrapped on electrical cable aluminium sheath 6, and the inner terminal that the other end is fixed on composite sheath terminal tail pipe is fixed on ear 2, realizes electrical connection; Composite sheath terminal tail infratubal port inwall is hot melt adhesive layer 5, first one deck heat-shrink tube is shunk at composite sheath terminal tail pipe during installation, gap reliable bond that heating composite sheath terminal tail pipe lower end makes PUR melt to fill tail pipe and cable, prescind this layer of heat-shrink tube after cooling, wrapped water blocking tape, glass fibre epoxy armoring tape again, one deck heat-shrink tube is shunk again after the solidification of glass fibre epoxy armoring tape, form water blocking tape lapping layer 8, glass fibre epoxy armour 9 and pyrocondensation tube layer 10 respectively, realize sealing, water proofing property and weatherability.
