Description

A kind of mineral insulated cable structure of LSOH anti-flaming

Technical field

Field of cable technology is the utility model is related to, a kind of mineral insulation of LSOH anti-flaming is particularly related to and prevents Thermoelectricity cable structure.

Background technology

Electric wire refers to the wire rod for electric power, communication and associated transport purposes, is to convey electric energy, transmission information and enter Row electromagnetic conversion and the various motors of manufacture, electrical equipment, the indispensable basic equipment of instrument institute.Our times resource is increasingly tight , it is also extremely strict to material used in electric wire, for the electronic material for lead frame, terminal, connector etc., Fundamental characteristics as product, it is desirable to which high intensity and high electric conductivity or thermal conductivity have both.

The growth of China's economic continuously and healthily, provides the huge market space for cable products, and Chinese market is strong Temptation so that sight is all focused on Chinese market by the world, in short decades of reforming and opening up to the outside world, Chinese cable manufacturing industry institute The huge production capacity formed allows the world to regard with special esteem.With China electric power industry, data communication industry, urban track traffic industry, The continuous expansion of the industry size such as car industry and shipbuilding, the demand of electric wire will also be increased rapidly, following electric wire Industry also has huge development potentiality.

With the popularization of power cable, cable fault rate also increases therewith.Cable often leads to electrical fire, surrounding Adjacent cable also destroys, and causes irremediable loss to whole power system, and cable is more easily damaged.And cable top layer Sheath burning after caused dense smoke make rescue task difficulty increase.

Utility model content

For deficiency of the prior art, the technical problems to be solved in the utility model is the provision of a kind of low smoke, zero halogen Fire-retardant mineral insulated cable structure.

In order to solve the above technical problems, the utility model is realized by following scheme：A kind of ore deposit of LSOH anti-flaming Thing insulated cable structure, the construction of cable include：

Sheath, the sheath are placed in outermost layer, and the sheath is halogen-free and low-smoke flame-retardant polyolefin sheathed；

The chain armor of copper strips, the chain armor of copper strips are placed in sheath；

Separation layer, the isolation are placed in copper ribbon continuous lock armor, and the separation layer is ceramic polyolefin separators；

At least one cable core, the outer layer of the cable core and intermediate layer be respectively ceramic polyolefin insulation layer, The wrapped flame retardant coating of synthetic mica, innermost layer are copper conductor；

The cable core is placed in separation layer, and the gap location between the cable core and the separation layer is filled with Glass cord；

The glass cord outer layer is wound with least one layer of glass fiber tape.

Further, the chain armor of the copper strips is layers of copper or albronze layer or aluminium lamination.

Further, the copper conductor includes folded tight more copper wires together.

Further, the cable core is provided with five, and its circular array is placed in separation layer.

Further,：The glass fiber tape is provided with two layers, and layer glass fiber band is in netted by glass fiber strand Tightly.

Relative to prior art, the beneficial effects of the utility model are：The mineral of the utility model LSOH anti-flaming are exhausted Edge fireproof cable structure does not allow easy firing, even if it produces few smog after burning, fire proofing can prevent the condition of a fire from expanding.

For the utility model construction of cable outermost layer using halogen-free and low-smoke flame-retardant polyolefin sheathed, the sheath has fire-retardant work With, even if burning after caused smog it is also few；

For the chain armor of copper strips with destroyed ability is prevented, the layer is screen layer；

Separation layer is ceramic polyolefin separators, therefore, can be with absorbing cable because ceramics have the cold fast function of effect The heat in portion also has heat sinking function to outside, while for isolating；

Ceramic polyolefin insulation layer is used to insulate, and avoids short circuit, and the wrapped flame retardant coating of synthetic mica is used to prevent fires.

The utility model construction of cable uses multiple fireprotection layers, construction of cable fire resistance property is greatly strengthened, can make Obtain power system stability.

Brief description of the drawings

Fig. 1 is the utility model construction of cable profile；

Fig. 2 is the utility model cable core structural representation；

Marked in accompanying drawing：The wrapped flame retardant coating 2 of copper conductor 1, synthetic mica, ceramic polyolefin insulation layer 3, glass cord 4th, the chain armor 7 of glass fiber tape 5, separation layer 6, copper strips, sheath 8.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model Define.
