Abstract
The invention discloses a flexible inorganic insulating fire-resisting cable. The flexible inorganic insulating fire-resisting cable is composed of one piece or a plurality of pieces of conductors, an inorganic substance packing layer and a sheathing layer from inside to outside in sequence, wherein the sheathing layer is made of metal materials and provided with ripples. According to the flexible inorganic insulating fire-resisting cable, conventional organic substances of plastics, rubber and the like are not adopted as an insulating sheath, inorganic substances with good insulating performance are adopted as an insulating layer instead, metal materials of copper, aluminum or aluminum and the like are used as conductors and adopted by the sheathing layer, and the defects that a metal sheath is uneasy to bend, install and transport are overcome through rippling process.
Description
Technical field
The present invention relates to cable processing and manufacturing technical field, relate in particular to a kind of flexible inorganic matter insulated fireproof cable.
Background technology
The inorganic matter insulated cable is that a class is used inorganics filled cable as insulating barrier, and it has superior insulation property and has conventional plastics or heat-resisting, fire resistance that rubber-covered is incomparable.But existing inorganic matter insulated cable also comes with some shortcomings, for example inorganics filled layer needs lapping layer parcel or oversheath parcel usually, and the limitation of lapping layer and the material property of oversheath own has influenced inorganics filled layer insulation, heat-resisting and fire-resistant performance is brought into play.
Summary of the invention
The purpose of this invention is to provide a kind of flexible inorganic matter insulated fireproof cable, do not adopt organic substances such as conventional plastics and rubber as insulation and sheath, but adopt the superior inorganic material of insulation property as insulating barrier, with metal materials such as copper, aluminum or aluminum alloy as conductor, and restrictive coating also is to adopt metal materials such as copper, aluminum or aluminum alloy, handle by ripple, changed the shortcoming that metallic sheath is not flexible, install and transport.
Technical solution of the present invention is:
Flexible inorganic matter insulated fireproof cable is made up of one or more conductor, inorganics filled layer, restrictive coating from the inside to the outside successively, and described restrictive coating is that ripple is made and be provided with to metal material.
As the further improved flexible inorganic matter insulated fireproof cable of the present invention, described conductor material is copper, aluminum or aluminum alloy, and described restrictive coating material is copper, aluminum or aluminum alloy.
As the further improved flexible inorganic matter insulated fireproof cable of the present invention, described inorganics filled layer material is a metal oxide.
As the further improved flexible inorganic matter insulated fireproof cable of the present invention, described inorganics filled layer material is a magnesium oxide.
As the further improved flexible inorganic matter insulated fireproof cable of the present invention, the inorganic matter insulation oxide of described inorganics filled layer material for handling through modification, described modification is treated to through hydrophobic material and handles.The inorganic matter insulation oxide can overcome common inorganic matter insulating joint and be difficult to carry out the problem that modification is handled.
Flexible inorganic matter insulated fireproof cable provided by the present invention has the following advantages: the refractory temperature height, can under 250 ℃ of temperature, use for a long time, and running under the particular surroundingss such as fire, do not influence use in the following short time of temperature about 1000 ℃, steady quality; Because inorganics filled layer has higher heat resistance, therefore can bear higher conductor heating temp, thereby it is long-pending to reduce cross-sectional area of conductor, the economical with materials cost; Sheath is that metal materials such as copper, aluminum or aluminum alloy are made, and can remove this part structure of cable zero line from, is directly used as zero line by restrictive coating; Cable insulation has heat conduction and heat radiation excellent characteristic, and because inorganics filled insulating barrier has certain fluidity, can not influence the normal use of cable when being subjected to the external force effect and causing distortion of the cable; The metallic sheath of cable is provided with ripple, has solved unbending shortcoming, is convenient to into dish transportation and installation; Need be when cable is installed by auxiliary material such as cable testing bridges, attractive in appearance and conserve space when guaranteeing the product installation; The insulation filling inorganic matter that is used to invent has solved the shortcoming of inorganic matter insulated cable moisture-sensitive through hydrophobic modified processing.
