Abstract
The utility model discloses a termite-resistant, ultraviolet-resistant, high-flame-retardance and oil-resistant cable for a locomotive vehicle. The cable comprises a conductor, wherein an isolating layer is wrapped outside the conductor; an insulating layer is molded outside the isolating layer in an extrusion mode; wear-resistant particles are uniformly distributed in the insulating layer; a plurality of tensile steel wires are annularly distributed in the insulating layer; and the section of each tensile steel wire is crescent. By adopting a single-layer insulating structure, the outer diameter of the cable is effectively reduced, the weight of the cable is reduced, the processing frequency and processing cost of the cable are reduced, the phenomena that the oil resistance, voltage resistance and cold resistance of the cable are reduced due to layering are eliminated, and the cable is high in flame retardance, low in halogen content, high in flexibility, and convenient to install and lay. Moreover, by arranging the crescent tensile steel wires and the wear-resistant particles in the insulating layer of the cable, the dragging resistance and wear resistance of the cable are effectively improved.
Description
Technical field:
The utility model relates to the car cable field, relates in particular to a kind of termite-proof, antiultraviolet high flame retardant oil resistant used for rolling stock cable.
Background technology:
At present, known rolling stock cable is divided into two types: one type is the insulation of standard wall thickness LSOH anti-flaming cross-linked polyolefin; Another kind of is the insulation of thin wall type LSOH anti-flaming cross-linked polyolefin.These two kinds of insulation are considered all to have solved the LSOH anti-flaming performance from the safety and environmental protection factor, in use prevent unexpected maximum on fire guarantee personal safety, but in the use with regard to cable self; Many know that the rolling stock cables are to follow going and the laying of track of vehicle, to south, arrive the west eastwardly from the north of the earth; Ubiquitous, the altering a great deal of environment, south is rainy relatively; The infringement of termite is arranged greatly easily; How fine the north is, and cable is unavoidably by ultraviolet long-term irradiation, and common cross-linked polyolefin insulation rolling stock cable can't satisfy performance termite-proof, antiultraviolet; Certainly very big hidden danger is arranged on one's body from what cable used, greatly reduce the useful life of cable.
In addition, anti-performance, the anti-wear performance of pulling of rated voltage 3kV and following car cable do not reach the requirement in the actual working environment process far away.
The utility model content:
To the prior art problem; The purpose of the utility model provides a kind of termite-proof, antiultraviolet high flame retardant oil resistant used for rolling stock cable; In actual working environment, satisfied performance termite-proof, antiultraviolet, anti-pull, anti-wear performance all is greatly enhanced.
The technical scheme of the utility model is following:
Termite-proof, antiultraviolet high flame retardant oil resistant used for rolling stock cable; Comprise conductor; It is characterized in that: conductor is surrounded with separator outward, and the outer extrusion moulding of separator has insulating barrier, is evenly distributed with abrasion resistant particles in the insulating barrier; Along annular spread several tension steel wires are arranged in the insulating barrier, several tension section of steel wire are crescent.
Described termite-proof, antiultraviolet high flame retardant oil resistant used for rolling stock cable is characterized in that: described conductor adopts the tin-coated copper filament tow to close the back adjacent layer structure that oppositely tangles again.
Described termite-proof, antiultraviolet high flame retardant oil resistant used for rolling stock cable is characterized in that: it is termite-proof, antiultraviolet LSOH anti-flaming cross-linked polyolefin that described insulating barrier adopts material.
The utility model has the advantages that:
The utility model adopts the individual layer insulation system, has reduced the outside diameter of cable effectively, has also alleviated cable weight; And reduced processing number of times and processing cost, and eliminated the situation that reduces product oil resistant, proof voltage and cold tolerance because of layering, cable has excellent anti--55 ℃ of performances simultaneously; After the cold test, the breakdown voltage test surplus is big, and the cable-flame retardant performance is good; Content of halogen is low, and the product softness is excellent, installs and lays conveniently; Because of not containing halogen in the material of making cable, a large amount of Halogen toxic gases that discharge during with 100 ℃ of grade common machine fare burnings are compared with dense smoke, only produce the gas of a small amount of LSZH during this product burning; Belong to the new generation of environment protection product, in environmental protection insulating material prescription, add the termite-proof agent of extraordinary low toxicity simultaneously, the termite-proof agent mainly forms with major-minor anti-termite agent cooperation such as tri-n-butyl tin, copper naphthenate, capsicim; Can play the good result of termite-proof and pest-resistant evil, in addition, in the insulating barrier of cable, set up meniscate tension steel wire; Abrasion resistant particles, promoted cable effectively anti-ly pull, antiwear characteristic.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Termite-proof, antiultraviolet high flame retardant oil resistant used for rolling stock cable; Comprise conductor 1, conductor 1 adopts the tin-coated copper filament tow to close the back adjacent layer structure that oppositely tangles again, the conductor 1 outer separator 2 that is surrounded with; Separator 2 outer extrusion moulding have insulating barrier 3 termite-proof, antiultraviolet LSOH anti-flaming cross-linked polyolefin material; The termite-proof agent that in the material prescription of environmental protection insulating barrier 3, adds extraordinary low toxicity simultaneously, termite-proof agent mainly form with major-minor anti-termite agent cooperation such as tri-n-butyl tin, copper naphthenate, capsicim, can play the good result of termite-proof and pest-resistant evil; Be evenly distributed with abrasion resistant particles 4 in the insulating barrier 3; Along annular spread several tension steel wires 5 are arranged in the insulating barrier 3, several tension steel wires 5 cross sections are crescent, promoted cable effectively anti-ly pull, antiwear characteristic.
