Abstract
The utility model discloses a fire -resistant silicon cable of pottery, include: conductor, copper sheath and outer jacket, wherein, copper sheath inner chamber is equipped with support chassis, the inner peripheral surface fixed connection of support chassis and copper sheath, support chassis is formed by the metal material preparation, and support chassis separates into a plurality of chambeies of placing with copper sheath inner chamber, and every is placed the intracavity and is equipped with the insulating sleeve, and the inner peripheral surface of placing the chamber is hugged closely to the outer peripheral face of insulating sleeve, the conductor sets up in the insulating sleeve, is equipped with the insulating packing layer between conductor and the insulating sleeve, and the filler in the insulating packing layer is ceramic inorganic refractory material, the outer jacket cladding is in the periphery of copper sheath. The utility model discloses make the stress grow of copper sheath, strengthened the anti offend ability of copper sheath, ensured the stability of copper sheath internal insulation packing layer, simultaneously, at insulating packing layer periphery cladding insulating sleeve, make the insulating packing layer reduce at insulating properties and lose under insulating properties's the condition even, can not take place insulation breakdown.
Description
Technical field
The utility model relates to power transmission technology field, particularly relates to a kind of ceramic fire resistant silicon cable.
Background technology
Use more fireproof cable for mineral insulated cable in the market.Mineral insulated cable (MineralInsulatedCable) is called for short MI cable, and when using as distribution, domestic custom is called fireproof cable.It is, by insulating mineral filler, the spaced apart of conductor is formed insulation effect.Because between conductor dependence insulating mineral filler insulate, once insulating mineral filler is subject to the effect of outside impulsive contact force or bending stress that dispersion or tomography occur, insulation property reduction can be made even to lose, thus generation insulation breakdown cause cable on fire.
Utility model content
Based on the technical problem that above-mentioned background technology exists, the utility model proposes a kind of ceramic fire resistant silicon cable, this cable non-deformability is strong, and distortion of the cable can be prevented to be expressed to insulating packing layer, makes the filler in insulating packing layer that dispersion occur and even ruptures; Meanwhile, strengthen the insulating properties of cable, guarantee that cable is when insulation property are even lost in the insulation property reduction of insulating packing layer, insulation breakdown can not occur.
The utility model proposes a kind of ceramic fire resistant silicon cable, comprise: conductor, copper sheath and outer jacket, wherein, copper sheath inner chamber is provided with support frame, support frame is fixedly connected with the inner peripheral surface of copper sheath, and support frame is made by metal material, and copper sheath inner chamber is separated into multiple placed cavity by support frame, be equipped with insulating sleeve in each placed cavity, and the outer peripheral face of insulating sleeve is close to the inner peripheral surface of placed cavity; Conductor is arranged in insulating sleeve, is provided with insulating packing layer between conductor and insulating sleeve, and the filler in insulating packing layer is ceramic inorganic refractory material; Outer jacket is coated on the periphery of copper sheath.
Preferably, support frame is made by metallic copper.
Preferably, support frame and copper sheath are formed in one.
Preferably, the inner chamber of copper sheath is separated into four placed cavities by support frame.
Preferably, conductor adopts copper core conductor.
In the utility model, copper sheath inner chamber is provided with support frame, and support frame is fixedly connected with the inner peripheral surface of copper sheath, and copper sheath inner chamber is separated into multiple placed cavity by support frame, be equipped with insulating sleeve in each placed cavity, and the outer peripheral face of insulating sleeve is close to the inner peripheral surface of placed cavity; The setting of support frame makes the stress grow of copper sheath, effectively improves the crash-protective characteristics of copper sheath, ensure that the stable of insulating packing layer in copper sheath; Meanwhile, at insulating packing layer periphery coated insulation sleeve, insulating packing layer is even ruptured in generation dispersion, when insulation property are even lost in insulation property reduction, insulation breakdown can not occur.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of ceramic fire resistant silicon cable that the utility model proposes.
Embodiment
Below, by specific embodiment, the technical solution of the utility model is described in detail.
As shown in Figure 1, Fig. 1 is the structural representation of a kind of ceramic fire resistant silicon cable that the utility model proposes.
With reference to Fig. 1, a kind of ceramic fire resistant silicon cable that the utility model embodiment proposes, comprising: conductor 1, copper sheath 2 and outer jacket 3, wherein, copper sheath 2 inner chamber is provided with support frame 4, and support frame 4 and copper sheath 2 are formed in one, and support frame 4 is made by metallic copper; The setting of support frame 4 makes the stress grow of copper sheath 2, effectively improves the crash-protective characteristics of copper sheath 2, ensure that the stable of insulating packing layer 6 in copper sheath 2.
Copper sheath 2 inner chamber is separated into four placed cavities by support frame 4, is equipped with insulating sleeve 5 in each placed cavity, and the outer peripheral face of insulating sleeve 5 is close to the inner peripheral surface of placed cavity; Conductor 1 adopts copper core conductor, and conductor 1 is arranged in insulating sleeve 5, is provided with insulating packing layer 6 between conductor 1 and insulating sleeve 5; When insulating packing layer 6 is when the effect by impulsive contact force or bending stress issues loose or fracture estranged, insulating sleeve 5 can be avoided, because even losing absolutely because insulation property reduce and insulation breakdown can occur between cable core and cable core, causing the problem of cable fire; Filler in insulating packing layer 6 is ceramic inorganic refractory material, and ceramic inorganic refractory material itself can not cause fire, can not burn or combustion-supporting, and therefore this kind of cable can have good fire line; Outer jacket 3 is coated on the periphery of copper sheath 2.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection range of the present utility model.
