The purpose of this utility model is for the above-mentioned problems in the prior art, provide a kind of fire prevention, and anti-seismic performance is got well and had resistance to torsion Novel fireproof cable.
The purpose of this utility model realizes by following technical proposal: a kind of Novel fireproof cable, it is characterized in that: comprise silicon rubber oversheath successively from outside to inside, flame-retardant insulating material layer and proof copper-wire braided screen, some silicon rubber inner sheaths are also provided with in described proof copper-wire braided screen, conductor is provided with in described silicon rubber inner sheath, described silicon rubber inner sheath is fan page shape, and some silicon rubber inner sheath extrados and proof copper-wire braided screen offset, adjacent silicon rubber inner sheath side offsets, silicon rubber resistance to compression bar is provided with in the space that some silicon rubber inner sheath intrados surround, described silicon rubber resistance to compression bar circumference is angularly distributed with the some bar shaped bulges with silicon rubber resistance to compression bar one, and described bulge and silicon rubber inner sheath intrados offset, also reinforcement is provided with in described silicon rubber resistance to compression bar.
Owing to having flame-retardant insulating material layer, therefore this cable has certain fire protection flame retarding, owing to being provided with conductor in silicon rubber inner sheath, silicon rubber inner sheath is fan page shape, adjacent silicon rubber inner sheath side offsets, therefore when outside is squeezed, a silicon rubber inner sheath is to internal strain, then other silicon rubber inner sheath side then has reverse thrust to the silicon rubber inner sheath of distortion, therefore a kind of dynamic balance is formed, therefore there is good antidetonation crushing resistance, and be provided with silicon rubber resistance to compression bar in the space surrounded of some silicon rubber inner sheath intrados, silicon rubber resistance to compression bar circumference is angularly distributed with the some bar shaped bulges with silicon rubber resistance to compression bar one, and bulge and silicon rubber inner sheath intrados offset, therefore to silicon rubber inner sheath, also there is good supportive by bulge, make this cable compressive property better.
In above-mentioned a kind of Novel fireproof cable, described silicon rubber oversheath cross section is in falling water-drop-shaped.
Therefore avoiding silicon rubber surface of outer sheath accumulated snow to increase the weight of cable makes it fracture.
In above-mentioned a kind of Novel fireproof cable, described flame-retardant insulating material layer comprises fire lagging, insulating waterproof layer and flame retardant bed from outside to inside successively.
In above-mentioned a kind of Novel fireproof cable, in described bulge, be filled with gas.
In above-mentioned a kind of Novel fireproof cable, described reinforcement is that steel wire fibre material is made, and described silicon rubber oversheath is that high-temperature-resisting silicon rubber is made, and described proof copper-wire braided screen is woven by tinned copper wire and forms.
Compared with prior art, the utility model tool has the following advantages:
Owing to having flame-retardant insulating material layer, therefore this cable has certain fire protection flame retarding, owing to being provided with conductor in silicon rubber inner sheath, silicon rubber inner sheath is fan page shape, adjacent silicon rubber inner sheath side offsets, therefore when outside is squeezed, a silicon rubber inner sheath is to internal strain, then other silicon rubber inner sheath side then has reverse thrust to the silicon rubber inner sheath of distortion, therefore a kind of dynamic balance is formed, therefore there is good antidetonation crushing resistance, and be provided with silicon rubber resistance to compression bar in the space surrounded of some silicon rubber inner sheath intrados, silicon rubber resistance to compression bar circumference is angularly distributed with the some bar shaped bulges with silicon rubber resistance to compression bar one, and bulge and silicon rubber inner sheath intrados offset, therefore to silicon rubber inner sheath, also there is good supportive by bulge, make this cable compressive property better.
