Abstract
The utility model discloses a fire -resistant double -shielded gopher protected cable of tensile relates to cable technical field, solved ordinary cable a little less than the pull resistance, do not prevent fires, do not shield the effect and poor and bitten broken the scheduling problem by the mouse easily, the utility model discloses a four group's cable cores, every group cable core all include conductor, cladding the insulating layer of conductor outside, cladding on the internal shield layer of insulating layer outside, four group's cable cores are provided with a packet strip winding outward, are provided with the filling layer between package strip winding and the four group's cable cores, are provided with the enhancement core in the filling layer, wrap the strip winding outward in proper order the cladding have flame retardant coating, external shielding layer, armor, hot pepper sketch map layer, oversheath layer, comparing pull resistance reinforcing and double shielding with ordinary cable and making the shielding effectual, fire -resistant, life that the protection against rodents has further prolonged the cable reduces use cost simultaneously.
Description
Technical field
The present invention relates to field of cables, relate to a kind of tension fire-resistant double shield layer rodent-resistant cable more specifically
.
Background technology
The application of cable very wide, common is mainly used in electric power system, the information transmission system etc., the cable of power information comprises local cable, camera cable, light cable etc., mouse is rodent, tooth grows all the life, every day must keep its physiological habit with the tooth that the object quick abrasion fast-growing that bites is long, and the distinctive smell of plastics makes plastics become the long object that bites of muroid, mouse posts the dark corner staying in subterranean stream building more, cable tunnel, groove, cable shafts etc. all become the best place that mouse perches, therefore these cables are often bitten by mouse, damaged by rats is one of current main harm to cable, the cable that damaged by rats causes destroys mainly outer protective sleeve and will be worn and cause cable to intake, cause power failure, the situations such as communicating interrupt, damaged by rats is destroyed and is got rid of difficulty, also inconvenience is brought to maintenance, the tensile strength of the shielded type cable of some is inadequate at present, shield effectiveness is bad, easy reduction cable life.
Summary of the invention
The present invention overcomes above-mentioned technical deficiency, provides that a kind of shield effectiveness is good, tensile strength large, the tension fire-resistant double shield layer rodent-resistant cable of fireproof anti-rat-bite.Can bite capsicim layer after mouse son gnaws through oversheath, capsicim produces strong impulse to mouse, orders about mouse and abandons biting
The present invention to achieve these goals concrete by the following technical solutions:
A kind of tension fire-resistant double shield layer rodent-resistant cable, it is characterized in that, comprise four groups of cables core, often organize cable core to include conductor, be coated on insulating barrier outside conductor, be coated on internal shield outside insulating barrier, four groups of cables core are outside equipped with and hold band, hold between band and four groups of cables core and be provided with packed layer, in packed layer, be provided with strengthening core, hold outside band and be coated with fireprotection layer, outer shielding layer armour, capsicim layer, external sheath layer successively.
Described four groups of cables core become circumference uniform distribution, strengthen cable core and are positioned at circle centre position.
The zinc-coated wire that described strengthening core is 0.15 ~ 0.22mm by diameter twists again and forms, and the strengthening core outer wrapping restrictive coating after multiple strand, restrictive coating is insulating material.
Described fireprotection layer is thickness is 0.2 ~ 0.4mm, and width is mica tape or the glass fiber tape of 5 ~ 15mm.
Described armour is steel wire armor layer, is that galvanized steel strip twists again and forms by diameter.
The material of described packed layer is asbestos.
Beneficial effect of the present invention is as follows:
Can bite capsicim layer after mouse son gnaws through oversheath, capsicim produces strong impulse to mouse, orders about mouse and abandons biting, thus protection cable is by damaged by rats; The zinc-coated wire that strengthening core is 0.15 ~ 0.22mm by diameter twists again and forms, the tensile strength of this material is good, armour, except strengthening the mechanical protection such as tensile strength, compression strength and increasing the service life, can also improve cable interference free performance by shielding protection; By the double layer screen of two-layer screen, shield effectiveness strengthens.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tension of the present invention fire-resistant double shield layer rodent-resistant cable;
Reference numeral: 1-cable core, 1-1-conductor, 1-2-insulating barrier, 1-3-internal shield, 2-strengthening core, 3-restrictive coating, 4-packed layer, 5-holds band, 6-fireprotection layer, 7-outer shielding layer, 8-armour, 9-capsicim layer, 10-external sheath layer.
Embodiment
In order to those skilled in the art person better understands the present invention, below in conjunction with accompanying drawing and following examples, the present invention is described in further detail.
Embodiment
As shown in Figure 1, the invention provides a kind of tension fire-resistant double shield layer rodent-resistant cable, comprise four groups of cables core 1, often organize cable core 1 to include conductor 1-1, be coated on insulating barrier 1-2 outside conductor 1-1, be coated on internal shield 1-3 outside insulating barrier, four groups of cables core 1 are outside equipped with and hold band 5, hold between band 5 and four groups of cables core 1 and be provided with packed layer 4, be provided with strengthening core 2 in packed layer 4, hold outside band 5 and be coated with fireprotection layer 6, outer shielding layer 7 armour 8, capsicim layer 9, external sheath layer 10 successively; Can bite capsicim layer after mouse son gnaws through oversheath, capsicim produces strong impulse to mouse, orders about mouse and abandons biting, even if capsicim layer will be worn
In the present embodiment, four groups of cable core 1 one-tenth circumference uniform distributions, strengthen cable core 2 and are positioned at circle centre position.
In the present embodiment, the zinc-coated wire that described strengthening core 2 is 0.15 ~ 0.22mm by diameter twists again and forms, and the strengthening core 2 outer wrapping restrictive coating 3 after multiple strand, restrictive coating 3 is insulating material.
In the present embodiment, fireprotection layer 6 for thickness be 0.2 ~ 0.4mm, and width is mica tape or the glass fiber tape of 5-15mm.
In the present embodiment, armour 6 is steel wire armor layer, is that galvanized steel strip twists again and forms by diameter.
In the present embodiment, the material of packed layer 4 is asbestos.
