Abstract
The utility model discloses a kind of three core ribbon insulated type cables, comprise three insulated wire cores, every root insulated wire cores is by conductor wire core holding certain thickness phase insulating barrier, three insulated wire cores are twisted together and turnkey one deck tape insulation layer formation cable core, described cable core place is filled with filler, described tape insulation layer shares a metallic sheath outward, and be provided with inner liner between described metallic sheath and cable core, described metallic sheath is surrounded by armour and serving outward successively.The utility model structural design is simple, it is easy, cost-saving to manufacture, and effectively improves the serviceability of product, has excellent heat resistance, physical and mechanical properties, electrical insulation capability.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of three core ribbon insulated type cables.
Background technology
Along with the develop rapidly of China's economy, the skyscraper, subway, nuclear power station, shipbuilding industry, optoelectronic communication etc. of China develop at a speed unheard of before especially, and the consumption of electric wire also increases rapidly thereupon.Power cable (power cable), for transmitting and distribute the cable of electric energy.Be usually used in Urban Underground electrical network, the lead line in power station, the in-line power of industrial and mining enterprises and cross river, excessively extra large submarine transmission line.In power circuit, the proportion shared by cable increases just gradually.
Utility model content
For the problems referred to above, the utility model provides a kind of three core ribbon insulated type cables.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of three core ribbon insulated type cables, comprise three insulated wire cores, every root insulated wire cores is by conductor wire core holding certain thickness phase insulating barrier, three insulated wire cores are twisted together and turnkey one deck tape insulation layer formation cable core, described cable core place is filled with filler, described tape insulation layer shares a metallic sheath outward, be provided with inner liner between described metallic sheath and cable core, described metallic sheath is surrounded by armour and serving outward successively.
Further, described phase insulating barrier and tape insulation layer are that oil-paper surrounds on conductor wire core with the cable paper helically of one fixed width, form after vacuum drying treatment with impregnating agent dipping.
Further, in described tape insulation layer, electric field strength direction out of plumb oil-paper paper, has the component along oil-paper paper.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
The utility model structural design is simple, it is easy, cost-saving to manufacture, and effectively improves the serviceability of product, has excellent heat resistance, physical and mechanical properties, electrical insulation capability.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of three core ribbon insulated type cables of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
A kind of three core ribbon insulated type cables, comprise three insulated wire cores, every root insulated wire cores is by conductor wire core 1 holding certain thickness phase insulating barrier 2, three insulated wire cores are twisted together and turnkey one deck tape insulation layer 3 forms cable core, described cable core place is filled with filler 4, described tape insulation layer shares a metallic sheath 5 outward, is provided with inner liner 6 between described metallic sheath 5 and cable core, and described metallic sheath 5 is outer is surrounded by armour 7 and serving 8 successively.Structural design is simple, it is easy, cost-saving to manufacture, and effectively improves the serviceability of product, has excellent heat resistance, physical and mechanical properties, electrical insulation capability.
Described phase insulating barrier 2 and tape insulation layer 3 are that oil-paper surrounds on conductor wire core 1 with the cable paper helically of one fixed width, form after vacuum drying treatment with impregnating agent dipping.The impregnating agent viscosity of oil-paper is higher, not easily flows within the scope of cable operating temperature, but has comparatively low viscosity under dipping temperature, can ensure good dipping.Viscosity impregnating agent is generally mixed (bright stock accounts for 65 ~ 70%, and rosin accounts for 30 ~ 35%) by bright stock and rosin.Many countries adopt synthetic resin (as polyisobutene) to replace rosin, are mixed into low-voltage cable impregnating agent with bright stock.
In described tape insulation layer 3, electric field strength direction out of plumb oil-paper paper, has the component along oil-paper paper, general only for less than 10 kilovolts cables.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
