Abstract
The utility model discloses a fire -retardant track of insulating low smoke and zero halogen of high flexibility thin wall cable for transportation vehicles, this outside diameter of cable are 15 -30mm, including the syntropy hank to the zinc -plated soft copper conductor that sets up, zinc -plated soft copper conductor cladding in the noryl is insulating, the insulating cladding of noryl in the noryl sheath, the noryl insulation thickness be 0.18 -0.28mm. The utility model discloses a soft copper conductor of tin -plating, noryl insulation and noryl sheath do not use the filler material and around wrapping the material, have effectively reduced the external diameter of cable, have reduced the insulation thickness, small, the light in weight of its product.
Description
Technical field
The utility model belongs to field of cable technology, relates to a kind of cable for rail transit vehicles, specifically a kind of high flexibility thinwalled insulation cable for low-smoke zero-halogen flame-retardant track traffic vehicles.
Background technology
High flexibility thinwalled insulation cable for low-smoke zero-halogen flame-retardant track traffic vehicles particularly suitable is the rolling stock interior distribution cabinet of airtight, the environmental requirement harshness such as personnel concentrate relative to ultrahigh speed rolling stock etc. and power supply system at a high speed.
Rapidly, the control of motor-car unit, high speed unit becomes increasingly complex, and electrical control equipment gets more and more in national track traffic development in recent years, and its cabling requirements amount is also inevitable to be increased thereupon.But the space in locomotive is limited, so require that the insulation thickness reducing cable is as far as possible to reduce the outside diameter of cable.This just requires that the temperature resistant grade improving insulation is to improve the ampacity of cable, improves the mechanical and physical performance of insulation, oil resistance to improve the security performance of cable.
Authorization Notice No. CN201498233U discloses a kind of cable for rail transit vehicles, comprise cable core, screen and restrictive coating, the outer setting of cable core has screen, the outer setting of screen has restrictive coating, cable core comprises conductor and insulating barrier, conductor is made up of with core is stranded many tin-coated copper wires, and its stranded lay ratio is 10-20 times, and the outer wrap of every root conductor has the insulating barrier of 0.3-0.5mm.Technique scheme cable thickness is larger, and the space taken in locomotive is large.
Utility model content
The purpose of this utility model is to overcome prior art defect, provides a kind of volume little, lightweight high flexibility thinwalled insulation cable for low-smoke zero-halogen flame-retardant track traffic vehicles.
The purpose of this utility model can be achieved through the following technical solutions:
High flexibility thinwalled insulation cable for low-smoke zero-halogen flame-retardant track traffic vehicles, this outside diameter of cable is 15-30mm, comprises the zinc-plated soft copper conductor twisted in the same way to arranging; Described zinc-plated soft copper conductor is coated in Noryl insulation; Described Noryl insulating wrapped is in Noryl sheath; Described Noryl insulation thickness is 0.18-0.28mm.
The beneficial effects of the utility model: the utility model adopts zinc-plated soft copper conductor, Noryl to insulate and Noryl sheath, do not use packing material and wrapped material, effectively reduce the external diameter of cable, reduce insulation thickness, its small product size is little, lightweight.
Accompanying drawing explanation
The utility model to be further described below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that.
Fig. 1 is the utility model structural representation.
Embodiment
As Fig. 1, high flexibility thinwalled insulation cable for low-smoke zero-halogen flame-retardant track traffic vehicles, this outside diameter of cable is within the scope of 15-30mm, comprise the seven zinc-plated soft copper conductors 1 twisted in the same way to arranging, seven zinc-plated soft copper conductors 1 are coated in Noryl insulation 2 respectively, Noryl 2 thickness that insulate are 0.18-0.28mm, be coated on Noryl insulation 2 in seven zinc-plated soft copper conductors 1 be coated in Noryl sheath 3, the gap-fill between its zinc-plated soft copper conductor be modified polyphenyl ether material.
The utility model small product size is little, lightweight, with zinc-plated soft copper as conductor, modified polyphenyl ether material as the insulation of cable and sheath, multicore cable directly twist in the same way when stranding to, do not use packing material and wrapped material, directly sheath is extruded after stranding, effectively reduce the external diameter (cable size on average reduces about 28%) of cable, add the suppleness of product.The utility model use the product of modified polyphenyl ether material and PVC, low smoke and zero halogen polyene gently compared with there is following advantage:
(1) proportion of Noryl is about 1.0g/cm
3, and PVC is 1.3g/cm
3, loss of weight about 20%;
(2) Noryl is when burning, and smoke density is low, and its density is about 1.0, well below PVC and low-smoke halogen-free polyolefin, without poison gas release, and environmental protection more;
(3) dielectric strength of Noryl is higher than PVC, contributes to the insulation thickness of thinning cable;
(4) scrape abrasion resistance of Noryl can be about 3 times of XLPE, and the insulation thickness possibility of thinning like this cable is larger, contributes to improving wiring density.Insulation thickness can reduce 25% relative to XLPE, and weight about reduces by 40%.
The high flexibility thinwalled insulation cable for low-smoke zero-halogen flame-retardant track traffic vehicles that the utility model provides, product has the feature such as higher flexibility and heat-resisting, oil resistant, acid and alkali-resistance, cold-resistant, wear-resisting and ozone-resistant, and particularly suitable is the rolling stock interior distribution cabinet of airtight, the environmental requirement harshness such as personnel concentrate relative to ultrahigh speed rolling stock etc. and power supply system at a high speed.The zinc-plated soft copper conductor that this cable adopts, there is good pliability, its conductivity, mobility and wettability and satisfactory mechanical property, the modified polyphenyl ether material adopted is as the insulation of cable and sheath, this material has outstanding flame-retarding characteristic, and than the better chemical proofing of PVC and less density, its pliability can be demonstrate,proved cable and have well complete and electric property.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection range of the present utility model all should be belonged to.
Claims (1)
