Abstract

The invention discloses a below-35kV copper core and aluminum core coaxial composite plastic insulated cable comprising a cable core. The cable is characterized in that the cable core is provided with an inner conductor, a glass fiber filling layer, a first PVC insulating layer and an outer conductor from inside to outside; the inner conductor is formed by stranding a copper conductor and six aluminum conductors in a '1+6' structure; the outer conductor is formed by stranding the same number of copper conductors and aluminum conductors in an alternate arrangement way; and a second PVC insulating layer is arranged outside the cable core in an extruding way, an elastic buffer layer wraps the second PVC insulating layer, a galvanized armor layer is braided outside the elastic buffer layer, and an aluminum sheath is arranged outside the galvanized armor layer. The cable has the advantages of being resistant to high temperature, resistant to combustion, good in insulation performance, anti-extrusion, and the like.

Description

Below 35kv copper core aluminum core coaxial composite plastic insulated cable
Technical field
The present invention relates to electric wire field, be specifically related to a kind of below 35kv copper core aluminum core coaxial composite plastic insulated electro Cable.
Background technology
The most domestic used plastic power cable is quite varied, is usually used in the extraction of Urban Underground electrical network, electric station Circuit, the in-line power of industrial and mining establishment and the submarine transmission line in mistake river, excessively sea.The basic structure of the power cable of the type is by line Core (conductor), insulating barrier, screen layer and protective layer four part composition, its cost is relatively low, is suitable for large-scale use.Power cable In, plastic insulation material is usually cross-linking polyethylene materials, and its operating temperature of the power cable that this material is made, at 90 DEG C, also has Using operating temperature is the PVC material of 70 DEG C, and sheath material is usually PVC material, and this material has low cost, fire-retardant etc. excellent Point.
The problems and disadvantages that prior art exists:
Generally the conductor operating temperature of power cable is 60 DEG C, therefore uses the power cable shadow in external factor of PVC material Under sound, cable is easy to occur that conductor insulation temperature is too high and makes cable insulation is ineffective and causes line short, hit The phenomenon such as wear.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is provided that a kind of
For achieving the above object, the invention discloses a kind of below 35kv copper core, aluminum core coaxial composite plastic insulated cable, including Cable core, described cable core is provided with inner wire from inside to outside, glass fiber is filled, PVC insulating barrier and an outer conductor;Lead in described Body is formed by the frame mode of a copper conductor and six roots of sensation aluminium conductor employing " 1+6 " is stranded;Outer conductor is led by the copper that quantity is identical Body and aluminium conductor are spaced stranded forming;Extruding the 2nd PVC insulating barrier outside described cable core, the 2nd PVC insulating barrier is outer wrapped Elastic cord breaker, weaves zinc-plated armor outside elastic cord breaker, zinc-plated armor is externally provided with aluminium sheath.
Preferably, in described elastic cord breaker includes flexibility, pad pads outside flexibility, pad and pad outside flexibility in described flexibility Between be provided with some air bags.
Preferably, described copper conductor is identical with the diameter of aluminium conductor.
Preferably, the thickness of a described PVC insulating barrier is the 1/3 of the thickness of the 2nd PVC insulating barrier.
The beneficial effects of the present invention is:
1, the filling of the present invention uses glass fiber, and glass fiber is inorganic matter, does not burns, and will not produce harmful substance.
2, oversheath of the present invention is that metallic aluminium is made, and will not burn, and any has even if also will not produce under flame condition Evil gas.
3, cable entirety of the present invention is full symmetrical configuration, and inner and outer conductor is in concentric position, in electromagnetic energy is confined to Media between outer conductor, therefore has decay little, and shielding properties is high.
4, the elastic cord breaker of the present invention can effectively buffer from extraneous pressure, well protects cable each Layer is not extruded by the external world so that cable can work normally.
5, it is designed with PVC insulating barrier outside internal and external conductor of the present invention so that the insulating properties of cable is more preferable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the structural representation of the elastic cord breaker of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate The present invention rather than limit the scope of the present invention, after having read the present invention, each to the present invention of those skilled in the art The amendment planting the equivalent form of value all falls within the application claims limited range.
As it is shown in figure 1, the present invention provides a kind of below 35kv copper core, aluminum core coaxial composite plastic insulated cable, including cable Core, described cable core is provided with inner wire from inside to outside, the 3, the oneth PVC insulating barrier 4 and outer conductor filled by glass fiber;Lead in described Body is used by a copper conductor 1 and six roots of sensation aluminium conductor 2 that the frame mode of " 1+6 " is stranded to be formed;Outer conductor is by the identical copper of quantity Conductor and aluminium conductor are spaced stranded forming;Extrude the 2nd PVC insulating barrier 5 outside described cable core, the 2nd PVC insulating barrier outer around Bag elastic cord breaker 6, weaves zinc-plated armor 7 outside elastic cord breaker, zinc-plated armor is externally provided with aluminium sheath 8, and the fusing point of aluminum is 660 DEG C, generally it is difficult to fusing, is also only melted when aluminum pipe, does not has any harmful substance to produce.
As in figure 2 it is shown, described elastic cord breaker 6 include padding outside pad 61 and flexibility in flexibility in 63, described flexibility pad with It is provided with some air bags 62 between flexible outer pad.
This cable entirety is full symmetrical configuration, and inner and outer conductor is in concentric position, and electromagnetic energy is confined to internal and external conductor Between media, therefore there is decay little, shielding properties is high.
The above is only the preferred embodiment of the present invention, it is noted that come for those of ordinary skill in the art Saying, under the premise without departing from the principles of the invention, it is also possible to make some modification and improvement, these also should be regarded as belonging to the present invention Protection domain.
