Abstract
The invention discloses a kind of crosslinked polyetylene insulated nylon protection of electrical cable, including conductor, at the outer extruded insulation layer of conductor, outside insulating barrier, extrude sheath, outside sheath, extrude nylon overcoat, finally, extrude oversheath at cable outermost layer.The present invention uses nylon to replace steel-tape armouring so that cable has more flexibility, ageing-resistant so that the service life of cable is long.
Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of crosslinked polyetylene insulated nylon protection of electrical cable.
Background technology
The application history of existing thirties years of domestic crosslinked polyethylene (XLPE) insulated power cable, because it is good
Electrically and mechanically physical property, and have that production technology is simple, portable construction, transmission capacity big, mounting and installation and maintaining
Conveniently, not by advantages such as drop are limited, it is widely used in power system.
Mechanically damaged in order to prevent, power cable, at outer layer armored protective layer, forms armored cable.Cable adds armour
The purpose of dress layer is in addition to strengthening the mechanical protection such as tensile strength, comprcssive strength and increasing the service life, more importantly by screen
Cover protection improve cable interference free performance, also can in case pound, press, rack cable sheath after damage core cause short circuit, at present
Using steel-tape armouring, effect is undesirable, so will improvement further to armouring.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is provided that a kind of crosslinked polyetylene insulated nylon protection of electrical cable.
For achieving the above object, the present invention provides a kind of crosslinked polyetylene insulated nylon protection of electrical cable, including conductor,
Outside conductor, extrude the insulating barrier that thickness is 0.25-0.3mm, outside insulating barrier, extrude the sheath that thickness is 0.75-0.95mm,
Extruding the nylon overcoat that thickness is 0.1-0.2mm outside sheath, finally, extruding thickness at cable outermost layer is 1-2mm's
Oversheath.
Preferably, described conductor is round compacted comductor.
Preferably, described sheath is PVC sheath.
Preferably, described oversheath is PVC oversheath.
The beneficial effects of the present invention is:
Compared with prior art, present invention employs nylon overcoat and instead of steel band, substantially increase tensile strength, pressure resistance
The mechanical protections such as degree increase the service life, and add the flexibility of cable, not only act as shielding action and also act as buffer action；Adopt
Use interior oversheath, double shielding nylon overcoat so that cable has the mechanical protections such as more preferable tensile strength, comprcssive strength
Increase the service life.
Accompanying drawing explanation
Fig. 1 is the structural representation 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 crosslinked polyetylene insulated nylon protection of electrical cable, including conductor 1, leading
External extrude the insulating barrier 2 that thickness is 0.25-0.3mm, outside insulating barrier, extrude the sheath 3 that thickness is 0.75-0.95mm,
Extruding the nylon overcoat 4 that thickness is 0.1-0.2mm outside sheath, finally, extruding thickness at cable outermost layer is outside 1-2mm
Sheath 5.
Described conductor is round compacted comductor, improves the surface quality of stranded conductor, reduces conductor diameter, reduces strand
Space between single line in line, improves the distribution of cable electric fields uniform and plays good effect, and the use adding midium voltage cable is reliable
Property.
Described sheath uses PVC material to extrude and forms, and protects the flexibility of core.
Described oversheath uses PVC material to extrude and forms, and adds the flexibility of cable, the performance such as ageing-resistant.
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.
