Abstract
The utility model relates to a ceramic type fire-resistant wire which comprises a conductor. A ceramic type fire-resistant silicon rubber insulating layer is wrapped outside the conductor in a pressing mode. A nylon outer sheath is wrapped outside the ceramic type fire-resistant silicon rubber insulating layer in a pressing mode. The ceramic type fire-resistant wire has the advantages of being fire proof, fire resistant, high in inflaming retarding effect, self-lubricating, abrasion resistant, low-smoke, environmental-friendly, safe and reliable to use and convenient to process.
Description
Technical field
The utility model relates to a kind of electric wire, particularly a kind of ceramic fire-resistant wires that is applicable to rated voltage 450/750V.
Background technology
In electrified fast-developing today, unstable, the dangerous operation of electric wire, to bring massive losses to the country and people's the security of the lives and property, a large amount of poison gases that common flame-proof PVC electric wire produces when fire occurs suffocate the people even are dead, the spontaneous combustion of electric wire, combustion-supporting spreading of aggravating fire, how tackling the fire incident that electric wire causes has become a problem demanding prompt solution.
The electric wire that uses at present is mainly BLV, and its advantage is: lightweight, price is low, have preferably electrical insulating property, therefore is subject to consumer's welcome.But BLV in use exists potential safety hazard, when the breaking out of fire accident, the a large amount of dense smokes that produce because of the burning of electric wire and the halogen acid gas of release will have a strong impact on fire fighter's fire fighting and the safety of their life of crisis, produce so-called " secondary disaster "; And have corrosive halogen acid gas and also can corrode the facilities such as furniture and household electrical appliance.Along with people's environmental consciousness improves, BLV no longer satisfies people's needs, the substitute is have fire resistance, not halogen-containing environment-friendly cable.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of energy savings, has the ceramic fire-resistant wires of fireproof＝fire-proof, high temperature resistant, high flame retardant, halogen, high transmission rate, good combination property.
The utility model is realized by following measures:
A kind of ceramic fire-resistant wires of the present utility model comprises conductor, and described conductor is extruded with the fire-resisting ceramic silicone rubber insulating barrier outward, and described fire-resisting ceramic silicone rubber insulating barrier is extruded with nylon outer sheath outward.
Above-mentioned conductor is copper conductor or tinned copper conductor.
The beneficial effects of the utility model are: it has the advantage of fireproof＝fire-proof, high flame retardant, self-lubricating, wear-resisting, low cigarette environmental protection, and is safe and reliable, and easy to process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 conductor, 2 fire-resisting ceramic silicone rubber insulating barriers, 3 nylon outer sheaths.
Embodiment
As shown in Figure 1, a kind of ceramic fire-resistant wires of the present utility model comprises conductor 1, the conductor 1 outer fire-resisting ceramic silicone rubber insulating barrier 2 that is extruded with, the fire-resisting ceramic silicone rubber insulating barrier 2 outer nylon outer sheaths 3 that are extruded with.Conductor 1 is copper conductor or tinned copper conductor.
Fire-resisting ceramic silicone rubber insulating barrier 2 adopts squash types to extrude, and closely is extruded in conductor 1 bright and clean, smooth, the uniform upper surface of color and luster, and fire-resisting ceramic silicone rubber insulating barrier 2 is peeled off easily and do not damaged the tin coating of conductor or conductor.Ceramic silicon rubber is the good cable insulation material of a kind of environmental protection, superior electrical property, also has the performance of fireproof＝fire-proof, still can keep the unobstructed operation of circuit after the burning and not short circuit, opens circuit, and this is that other materials is incomparable.Thereby it is fire-resistant that cable is had, the characteristics of fire-retardant, Halogen, low cigarette.
Nylon outer sheath 3 closely is extruded in uniformly surface of smooth smooth, the color and luster of conductor, has remedied the mechanical property that the silicone rubber kinds cable is easily torn, and the self lubricity of cable, resistance to wear all are improved, and cable is laying when using more safe ready.
Above-described embodiment is described to be to specify this patent; though describe by specific term in the literary composition; but can not limit with this protection range of this patent; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
Claims (2)
1. a ceramic fire-resistant wires comprises conductor, it is characterized in that: described conductor is extruded with the fire-resisting ceramic silicone rubber insulating barrier outward, and described fire-resisting ceramic silicone rubber insulating barrier is extruded with nylon outer sheath outward.
2. described ceramic fire-resistant wires according to claim 1, it is characterized in that: described conductor is copper conductor or tinned copper conductor.
