Abstract
The utility model discloses a crosslinked polyethylene insulating branch cable comprising a main cable (1) and a branch cable (2). A crosslinked polyethylene insulating layer (3) is wrapped around a joint of the conductor (5) of the main cable (1) and the conductor (5) of the branch cable (2), and is connected with or imbricated on an insulating layer (6) of the main cable (1) and an insulating layer (6) of the branch cable (2). An outer sheath (4) is wrapped around the crosslinked polyethylene insulating layer (3). The highest rated operating temperature of the crosslinked polyethylene insulating branch cable can be increased to 90 degree centigrade. In addition, the adaptability and the mechanical property of the crosslinked polyethylene insulating branch cable are enhanced. Compared with a conventional branch cable, the crosslinked polyethylene insulating branch cable is protected by the extra outer sheath.
Description
Technical field
The utility model relates to a kind of branch cable, is specifically related to a kind of cross-linking polyvinyl insulation branch cable.
Background technology
Branch cable is multiplex to be used in the trunk cable of skyscraper as supply and distribution.Existing branch cable comprises main cable 1 and branch cable 2.Conductor 5 in the middle of main cable 1 includes with branch cable 2, be coated on conductor 5 outer insulating barrier 6 and restrictive coating 7 successively.
At present, the wrapped vinyl tape in junction of the conductor 5 of the conductor 5 of main cable 1 and branch cable 2.Adopt the wrapped meeting of vinyl tape to cause cable operation maximum amount fixed temperature to only have 70 ℃, the shortcomings such as bad mechanical property.
The utility model content
For the deficiency that prior art exists, the utility model purpose is to provide a kind ofly moves that the maximum amount fixed temperature is high, the cross-linking polyvinyl insulation branch cable of good mechanical property.
To achieve these goals, the utility model is to realize by the following technical solutions:
The utility model comprises main cable and branch cable, the junction of the conductor of main cable and the conductor of branch cable is surrounded with crosslinked polyetylene insulated layer, and crosslinked polyetylene insulated layer is connected or puts up with the insulating barrier of main cable and the insulating barrier of branch cable; The outer oversheath that is provided with of crosslinked polyetylene insulated layer.
Above-mentioned oversheath is connected with the restrictive coating of main cable, the restrictive coating of branch cable.
The utility model branch cable operation maximum amount fixed temperature can be brought up to 90 ℃; Simultaneously, adaptability and the mechanical performance of the utility model branch cable have been improved; With respect to existing branch cable many protection of one deck oversheath.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand,, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, the utility model comprises main cable 1 and branch cable 2.
The junction of the conductor 5 of main cable 1 and the conductor 5 of branch cable 2 is surrounded with crosslinked polyetylene insulated layer 3, and crosslinked polyetylene insulated layer 3 is connected or puts up with the insulating barrier 6 of main cable 1 and the insulating barrier 6 of branch cable 2.
Crosslinked polyetylene insulated layer 3 is outer is provided with oversheath 4, and oversheath 4 is connected with the restrictive coating 7 of main cable 1, the restrictive coating 7 of branch cable 2.
The utility model branch cable operation maximum amount fixed temperature can be brought up to 90 ℃; Simultaneously, adaptability and the mechanical performance of the utility model branch cable have been improved; With respect to existing branch cable many protection of one deck oversheath 4.
