Abstract
The invention discloses a kind of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber, it is little to have realized having good flexibility and weather-proof, waterproof, fire-retardant, low cigarette, Halogen, low-corrosiveness and smoke density, and minimum bending radius reaches 4D and alleviated cable construction greatly and lay difficulty.The present invention is achieved by following technical proposals: a kind of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber, comprise center conductor, wrapped successively laminated polyester film, insulating barrier, water blocking tape layer, high flame retardant belt and the restrictive coating in center conductor periphery, the cross-section of cable constitutes a multilayer concentric circle structure, wherein center conductor constitutes a core bundle body by many 6th class soft copper conductors, water blocking tape layer is that the bilateral structure lap wound of laying equal stress on is wrapped in outside the insulating barrier, and the high flame retardant belt is that the three-decker lap wound of laying equal stress on is wrapped in outside the water blocking tape layer.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber.
Technical background
Emphasis as top-priority field, the Eleventh Five-Year Plan period, will be built 18783 kilometers of track traffics to track traffic in China's Eleventh Five-Year Plan.Be not only the track traffic of urban inner, also comprise the rail rapid transit between the city, inter-city passenger rail and special line for passenger trains.But because that the space is laid in the track traffic electric power cable construction is narrow and small especially, subway particularly, and traditional track traffic electric power cable minimum bending radius is 6-10D (D is a cable size), it is bigger to make cable construction lay difficulty; Along with the increase of track traffic design load, the external diameter of cable also increases gradually, and conventional rails traffic power cable more and more can not satisfy the requirement of construction.
Summary of the invention
The present invention has overcome deficiency of the prior art, a kind of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber is provided, it has good flexibility and weather-proof, waterproof, fire-retardant, low cigarette, Halogen, low-corrosiveness and the little characteristics of smoke density, and its minimum bending radius reaches 4D, has alleviated cable construction greatly and has laid difficulty.
The objective of the invention is to be achieved by following technical proposals:
A kind of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber, comprise center conductor, wrapped successively laminated polyester film, insulating barrier, water blocking tape layer, high flame retardant belt and the restrictive coating in described center conductor periphery, the described cross-section of cable constitutes a multilayer concentric circle structure, wherein, described center conductor constitutes a core bundle body by many 6th class soft copper conductors, described water blocking tape layer is that the bilateral structure lap wound of laying equal stress on is wrapped in outside the insulating barrier, and described high flame retardant belt is that the three-decker lap wound of laying equal stress on is wrapped in outside the water blocking tape layer.
Above-mentioned a kind of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber, wherein, described restrictive coating adopts the low smoke and zero halogen elastomeric material.
Above-mentioned a kind of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber, wherein, described insulating barrier adopts the ethylene propylene diene rubber insulating material.
Owing to adopt technique scheme, waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber provided by the invention has such beneficial effect: have good flexibility and weather-proof, waterproof, fire-retardant, low cigarette, Halogen, low-corrosiveness and the little performance of smoke density, its minimum bending radius can reach 4D, has alleviated the laying difficulty of cable construction greatly.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber of the present invention.
Embodiment
Below by embodiment the present invention is described in further detail.
See also Fig. 1, there is shown the sectional view of waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber of the present invention, comprise center conductor 1, wrapped successively laminated polyester film 2, insulating barrier 3, water blocking tape layer 4, high flame retardant belt 5 and the restrictive coating 6 in center conductor periphery, the cross-section of cable constitutes a multilayer concentric circle structure, wherein, heart conductor 1 constitutes a core bundle body by many 6th class soft copper conductors; Water blocking tape layer 4 is wrapped in outside the insulating barrier 3 for the bilateral structure lap wound of laying equal stress on; High flame retardant belt 5 is wrapped in outside the water blocking tape layer 4 for the three-decker lap wound of laying equal stress on; Insulating barrier 5 adopts the ethylene propylene diene rubber insulating material; Restrictive coating 6 adopts the low smoke and zero halogen elastomeric materials, its pH value greater than 4.3, conductivity is 60% less than 10us/mm, minimum light transmittance.
In the waterproof flexible cable of insulated oil-proof elastic body jacket of ethylene propylene rubber of the present invention, center conductor 1 adopts the 6th class soft copper conductor to make cable conductor soft more.The ethylene propylene diene rubber insulating material of insulating barrier 3 also has the flexibility of rubber except that having good electrical insulation properties.The low smoke and zero halogen elastomeric material of restrictive coating 6 is compared with the pvc sheathing compound of prior art, except that softness more, also has environmental-protecting performance, the Halogen performance satisfies IEC60754-2 when making cable fire, low smoke performance satisfies IEC61034-1/2 during cable fire, and the mechanical performance of cable Halogen sheath, cryogenic stretching performance and high temperature pressure performance should satisfy the related request among IEC60811-1-1, IEC60811-1-4 and the IEC60811-3-1 respectively; Water blocking tape layer 4 can expand rapidly at short notice, and have and metal material and other adjacent materials favorable compatibility after meeting water, expands volume is increased, and stops up the space, thereby stops moisture further to the cable longtitudinal dispersion.The fire-retardant belt 5 of three floor heights makes cable can satisfy the category-A bunched burning test, has improved the fail safe that cable uses.
Above execution mode has been described in detail the present invention, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details in the execution mode should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
