Description
Technical field
The present invention relates to a kind of power cable, particularly a kind of power cable with crosslinked polyethylene insulating layer and thermoplastic elastomer sheath.
Background technology
At present, the various power cables outside of extensive use all is enclosed with one deck cable insulation in many buildings at home.All contain halogen in the cable insulation material mostly, this power cable is the material that transmits flare, enlarges the murther of fire scope, after such insulating material is lighted, can produce a large amount of dense smoke and the very strong hydrogen halide of corrosivity, jeopardize people's life, in case harm equipment and contaminated environment are breaking out of fire in the building, both entail dangers to life also can serious environment pollution.
Summary of the invention
The purpose of this invention is to provide a kind of power cable with crosslinked polyethylene insulating layer and thermoplastic elastomer sheath, can effectively solve problems such as to produce toxic gas behind the halogen-containing amount height of control cable, easy firing, burning of prior art.The present invention relates to a kind of power cable with crosslinked polyethylene insulating layer and thermoplastic elastomer sheath, comprise the cable inner core and wrap in the outer cable outer layer of cable inner core, described cable inner core inside is followed successively by conductor wire core and insulating barrier from inside to outside, described cable outer layer inside is followed successively by fire-retardant band and restrictive coating from inside to outside, is provided with the flame retardant type filler in the space between described cable outer layer and the cable inner core.Be provided with the flame retardant type filler in the space between the described cable inner core.The number of the cable inner core in the described cable outer layer is one or more.Described conductor wire core have two-layer or two-layer more than, every layer of conductor that has some strand with uiform section, per share have some conductor monofilament, twists to opposite between layer and the layer.The conductor monofilament of described conductor wire core is circle copper monofilament.Described round copper monofilament is that naked round annealed copper wire or overlay coating are the round copper monofilament of tin.Described insulating barrier is the crosslinked polyetylene insulated layer of Halogen.Described restrictive coating is a thermoplastic elastomer (TPE) TPE restrictive coating.Described fire-retardant band is a high flame retardant alkali-free glass cloth band.Described flame retardant type filler is the environment-protective glass fibre gasket for packing.Restrictive coating of the present invention is made by thermoplastic elastomer (TPE) TPE material, is the synthetic material of the physical and mechanical properties such as high resiliency of a kind of repetition processability that has thermoplastics concurrently and rubber.The present invention has characteristics such as waterproof, softness, anti-chemical, high-low temperature resistant, low smoke and zero halogen, can not discharge pernicious gas and smog during burning, is widely used in adapting to special dimensions such as military project, boats and ships, nuclear power, wind energy, railway, track traffic, magnetic suspension.
Description of drawings
Section of structure when accompanying drawing has four cable inner cores for the present invention.
Embodiment
Comprise the cable inner core among the figure and wrap in the outer cable outer layer of cable inner core, described cable inner core inside is followed successively by conductor wire core 1 and insulating barrier 2 from inside to outside, described cable outer layer inside is followed successively by fire-retardant band 3 and restrictive coating 4 from inside to outside, is provided with flame retardant type filler 5 in the space between described cable outer layer and the cable inner core.Be provided with flame retardant type filler 6 in the space between the described cable inner core.The number of the cable inner core in the described cable outer layer is one or more, generally selects with three, four or five.Described conductor wire core have two-layer or two-layer more than, every layer of lead group that has some strand with uiform section, per share lead group has some conductor monofilament, twists to opposite between layer and the layer.Conductor wire core is rounded by the geometry of a plurality of one-tenth cable cores that constitute with uiform section or different prismatic conductor wire core, and geometry is fixed, and stability is high, but very little to the curvature influence of cable.The conductor monofilament of described conductor wire core is circle copper monofilament.Described round copper monofilament is that naked round annealed copper wire or overlay coating are the round copper monofilament of tin, and this copper wire adopts high purity oxygen free copper to make.
Described insulating barrier, restrictive coating are made by the thermoplastic low-smoke halide-free CABLE MATERIALS.
Described insulating barrier is the crosslinked polyetylene insulated layer of Halogen, with the extrusion modling of Halogen crosslinked polyethylene insulation material, by crosslinked special processing, change polyethylene line style molecular structure into solid netted molecular structure, improved the electric property of product greatly, physical property, mechanical performance, ageing resistace and adaptive capacity to environment and other properties, not only high temperature resistant and have the advantages that not prolong the combustion and can not produce the very strong hydrogen halide of corrosivity.
Described restrictive coating is a thermoplastic elastomer (TPE) TPE restrictive coating.Thermoplastic elastomer (TPE) (Thermoplastic Elastomer-TPE) also claim thermoplastic elastomer (ThermoplasticRubber-TPR), it is a kind of material that has rubber and thermoplastics characteristic concurrently, show caoutchouc elasticity at normal temperatures, macromolecular material that again can plasticizing forming under the high temperature, have rubber like mechanical property and serviceability, can process and reclaim by thermoplastics again.Thermoplastic elastomer (TPE) can resemble the thermoplastics fast and effectively, economic processing rubber goods.With regard to processing, it is a kind of plastics; With regard to character, it is again a kind of rubber.Thermoplastic elastomer has many characteristics that are better than thermoset rubber.Thermoplastic elastomer (TPE) TPE has excellent reclaiming, waterproof, softness, anti-chemical (acid and alkali-resistance, anti-ozone, oil resistant etc.), and heatproof-65 ℃ is a kind of New-type halide-free environment-friendly materials.
Described fire-retardant band is a high flame retardant alkali-free glass cloth band; adopting aluminium borosilicate glass to take out system fibrage forms; the alkali metal thing is not more than 0.5%, directly becomes band behind the finished product, limit with lock, non-frangibility, character softness, wrapped smooth, stretching resistance extra-heavy; and this product is if suffer flame combustion; can not burn for about 900 ℃ in temperature, and stop flame to pass secluding air; the protection cable insulation exempts from often to be burnt, and the amount of smoke that produces during burning is few.
Described flame retardant type filler is the environment-protective glass fibre gasket for packing.Fire-retardant band and flame retardant type filler isolated insulation layer and restrictive coating are in case mutual bonding and influence the machinery, physics, electrical property etc. of cable between them.When cable is burnt, can absorb a large amount of heats, and form carburization zone, isolated gas-bearing formation, the protection insulating barrier is avoided burning, makes the loss of fire be unlikely further extension.
