Abstract
The invention discloses an anti-aging low-voltage power cable for rail transport. The anti-aging low-voltage power cable for rail transport comprises a cable core which is synthesized by a plurality of insulated wire cores. A belting layer is coated outside the power cable, a lining layer and an armor layer are sequentially coated outside the belting layer, and a protecting jacket is coated on the outermost layer of the power cable. The insulated wire cores are piece-shaped or block-shaped and are composed of conductors and insulating layers coated outside the conductor. According to the anti-aging low-voltage power cable for rail transport, the problems of cable breakdown, declining of insulation resistance and the like which are caused by water branches aging and insulation damped and aging during real manufacture and laying running time are solved, so that the safety is guaranteed. The anti-aging low-voltage power cable for rail transport has the advantages of anti-aging, high carrying capacity, long service life and the like.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of anti-aging track traffic lv power cable.
Background technology
Along with the fast development of national economy, all trades and professions also sharply increase the demand of cable.Particularly in recent years, along with the develop rapidly of track traffic, the demand of track traffic with lv power cable also constantly increased.The weak point that present lv power cable exists is, mostly adopts organosilane crosslinked polyethylene as main insulation material, in actual production with lay when moving, it is aging water tree to appear, humidified insulation is aging, thereby causes cable breakdown, degradation phenomenon under insulation resistance; In addition, this kind insulation material to reach crosslinked performance must be by satisfying performance requirement through a few hours in the environment of high-temperature water or steam.While technique is loaded down with trivial details, water easily is penetrated in insulation, causes potential safety hazard, can not satisfy the demand that lv power cable is used in current track traffic.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of anti-aging, ampacity is high, the track traffic lv power cable of long service life.
A kind of anti-aging track traffic lv power cable of the present invention comprises cable core, and its cable core is by stranded the forming of some eradication edge cores, and at cable core outer cladding belting layer, belting layer extrudes inner covering, armour outward successively, extrudes oversheath at the cable outermost layer.
Further improve, described insulated wire cores is the sheet bulk, is by conductor and is extruded in the outer insulating barrier of conductor and consists of.
Further improve, described armour adopts the clad steel band gap to put up lapping structure.
Further improve, described insulating barrier through UV-irradiation, reaches three-dimensional netted cross-linked polyolefin molecular structure by extrusion molten again.
Beneficial effect of the present invention:
1, the present invention adopts irradiation ultraviolet light cross-linking insulating material of polyethylene, by extrusion molten, through UV-irradiation, reaches three-dimensional netted cross-linked polyolefin molecular structure.
2, in the present invention, the insulated wire cores processing technology is simple, need not by warm water crosslinking, without micro-moisture, can directly enter next procedure after machining in material.
3, inner covering of the present invention adopts halogen-free low-smoke flame retardant material to consist of, and is applicable to the crowded places such as city underground, track traffic.
4, to take the clad steel band gap to put up wrapped in the present invention, consists of the armature of cable layer, prevents extraneous mechanical damage, improves the useful life of cable.
5, the present invention adopts anti-cracking low-smoke halogen-free polyolefin sheath, has solved the easily problem of cracking of halogen-free flameproof sheath.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of anti-aging track traffic lv power cable of the present invention, comprise cable core, its cable core is by stranded the forming of some eradication edge cores, insulated wire cores is by conductor 1 and adopt the insulating barrier 2 of irradiation ultraviolet light cross-linking insulating material of polyethylene to consist of, its insulating barrier 2 through UV-irradiation, reaches three-dimensional netted cross-linked polyolefin molecular structure by extrusion molten.Adopt halogen-free flameproof band belting layer 3 in the cable core outer cladding, extrude the inner covering 4 that adopts halogen-free low-smoke flame retardant material outside belting layer 3, the outer steel-tape armouring layer 5 that adopts the clad steel band gap to put up lapping structure, the oversheath 6 that extrudes the anti-cracking of employing low-smoke halogen-free polyolefin at the cable outermost layer of being provided with of inner covering 4.
The invention provides a kind of anti-aging track traffic thinking and the implementation method of lv power cable; concrete application approach is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
