Abstract
The utility model discloses a kind of fire-resisting cable transition joint, in order to connect two cables, comprise the tube connector be sequentially arranged on from inside to outside outside cable conductor, semiconductor tape, shielded-plate tube, insulation intermediate connector, copper mesh, water blocking tape, inorganic endothermic layer, Ceramic silicon rubber layer and sheath.Tube connector is crimped on the cable conductor of two docking.Inorganic endothermic layer is can absorb heat when being heated and can discharge the inorganic endothermic layer of steam, this endothermic process itself can play cooling effect, and water vapour volatilization can take away heat continuously, temperature is reduced, this can improve the fire resistance of transition joint, avoid the electric power conveying hidden danger caused because fire-resisting cable transition joint is not fire-resistant in power transmission system, ensure people's security of the lives and property.Ceramic silicon rubber layer can the housing of ablated one-tenth ceramic-like, and this housing can stop burning away of flame, plays the effect of isolated extraneous flame, thus protection cable joint is not damaged.
Description
Technical field
The utility model relates to a kind of cable intermediate joint, particularly relates to a kind of fire-resisting cable transition joint.
Background technology
At present, the cable in power transmission system has fire-resistant function, but does not but have fire-resistant function as the transition joint of stube cable, and this brings hidden danger to the safety and stability of power transmission system.
Utility model content
The purpose of this utility model is to provide a kind of cable intermediate joint with fire-resistant function.
For achieving the above object, the utility model provides a kind of fire-resisting cable transition joint, in order to connect two cable end pieces, comprise the tube connector be sequentially arranged on from inside to outside outside cable conductor, semiconductor tape, shielded-plate tube, insulation intermediate connector, copper mesh, water blocking tape, inorganic endothermic layer, Ceramic silicon rubber layer and sheath.Tube connector is crimped on the cable conductor of two docking.Inorganic endothermic layer is can absorb heat when being heated and can discharge the inorganic endothermic layer of steam.
Preferably, described inorganic endothermic layer is that fiber fixed inorganic heat-absorbing material is made.
Preferably, described inorganic endothermic layer is the one in magnesium hydroxide inorganic endothermic layer, aluminium hydroxide inorganic endothermic layer, hydrazine aluminum sulfate potassium inorganic endothermic layer, hydrated calcium sulfate inorganic endothermic layer, afwillite inorganic endothermic layer or composite inorganic heat-sink shell.
Preferably, to be that Ceramic silicon rubber is fire-resistant be entwined described Ceramic silicon rubber layer.
Preferably, water blocking tape is wound with further between described insulation intermediate connector and copper mesh.
The transition joint of the utility model fire-resisting cable has inorganic endothermic layer and Ceramic silicon rubber layer, inorganic endothermic layer can discharge water vapour when being heated to a certain degree, absorb heat in the process of inorganic endothermic layer release water vapour, this endothermic process itself can play cooling effect, and water vapour volatilization can take away heat continuously, temperature is reduced, this can improve the fire resistance of transition joint, avoid the electric power conveying hidden danger caused because fire-resisting cable transition joint is not fire-resistant in power transmission system, ensure people's security of the lives and property.Separately, Ceramic silicon rubber layer also has fire-resistant function, even if the ablated housing that also can change into ceramic-like, this housing can stop burning away of flame, plays the effect of isolated extraneous flame, thus protection cable joint is not damaged.
Accompanying drawing explanation

Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
Refer to Fig. 1, the transition joint of the utility model fire-resisting cable, in order to connect two cable end pieces, cable end piece need be peeled off and expose cable insulation 1 and cable conductor 2.
Fire-resisting cable transition joint comprises the tube connector 3 be sequentially arranged on from inside to outside outside cable conductor 2, semiconductor tape 4, shielded-plate tube 5, insulation intermediate connector 6, copper mesh 7, water blocking tape 8, inorganic endothermic layer 9, Ceramic silicon rubber layer 10 and sheath 11.
Tube connector 3 is crimped on the cable conductor 2 of two docking.
Stress cone is provided with in insulation intermediate connector 6.
Inorganic endothermic layer 9 is can absorb heat when being heated and can discharge the inorganic endothermic layer of steam.
In the present embodiment, inorganic endothermic layer 9 is made for fiber fixed inorganic heat-absorbing material, can certainly adopt other fixed forms.
Inorganic endothermic layer 9 can be the one in magnesium hydroxide inorganic endothermic layer, aluminium hydroxide inorganic endothermic layer, hydrazine aluminum sulfate potassium inorganic endothermic layer, hydrated calcium sulfate inorganic endothermic layer, afwillite inorganic endothermic layer or composite inorganic heat-sink shell.Composite inorganic heat-sink shell is that two or more compounds in magnesium hydroxide, aluminium hydroxide, hydrazine aluminum sulfate potassium, hydrated calcium sulfate obtain.
Ceramic silicon rubber layer 10 is preferably that Ceramic silicon rubber is fire-resistant to be entwined.
Preferably, water blocking tape (not shown) is wound with further between insulation intermediate connector 6 and copper mesh 7.
In sum, the transition joint of the utility model fire-resisting cable has inorganic endothermic layer 9 and Ceramic silicon rubber layer 10, inorganic endothermic layer 9 can discharge water vapour when being heated to a certain degree, absorb heat in the process of inorganic endothermic layer release water vapour, this endothermic process itself can play cooling effect, and water vapour volatilization can take away heat continuously, temperature is reduced, this can improve the fire resistance of transition joint, avoid the electric power conveying hidden danger caused because fire-resisting cable transition joint is not fire-resistant in power transmission system, ensure people's security of the lives and property.
Separately, Ceramic silicon rubber layer 10 also has fire-resistant function, even if the ablated housing that also can change into ceramic-like, this housing can stop burning away of flame, plays the effect of isolated extraneous flame, thus protection cable joint is not damaged.
The utility model is not limited to above-mentioned embodiment, and those skilled in the art also can make multiple change accordingly, but to be anyly equal to the utility model or similar change all should be encompassed in the scope of the utility model claim.
