The cable comprises at least a group of core wires, inorganic fillers, a second ceramic fireproof fire resistant composite band, and a low smoke zero halogen inflaming retarding polyolefin sheath; outer sides of the core wires are wrapped by the second ceramic fireproof fire resistant composite band in a coiled manner; the inorganic fillers are disposed between each of the core wires and the second ceramic fireproof fire-resistant composite band, and among core wires; the second ceramic fireproof fire-resistant composite band is wrapped by the low smoke zero halogen inflaming retarding polyolefin sheath in an extruded manner. Compared to the prior art, the cable provided in the utility model is non-absorbent, has advantages of good fire resistant performance, waterproof, moisture-proof, and mechanical performances, environmental protection, and low costs.
Description
Technical field
The utility model belongs to the cable technology field, particularly a kind of ceramic fireproof＝fire-proof cable.
Background technology
At present, mainly with the traditional handicraft structure of Mica tape conductor, minority is used mineral insulated cable to widely used fire-resisting cable.Tradition Mica tape cable, the mica tape fire resistance period is short, and residue is floury structure after the burning, therefore, can not continue to play a role, and, mica tape contains the glass fiber composition, glass fiber is that tiny fiber material is made, and frangibility is floating, in process of production in the floating air, the operator sucks in the lung, can't get rid of, and causes huge infringement to health.Mineral insulated cable, fire-resistant respond well, but because production equipment needs special equipment, take up an area large, many, the apparatus expensive of investment, and complex manufacturing, production length are limited to, and need welding, exist and lay the shortcomings such as inconvenience, maintenance cost height, do not form large-scale production always.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the defective that prior art exists, and provides a kind of fire-resistant effective, the cable of environmental protection.
The technical solution adopted in the utility model comprises at least one core assembly line, inorganic fillings, the second ceramic fireproof＝fire-proof composite band and halogen-free and low-smoke flame-retardant polyolefin sheathed;
Every core assembly line includes conductor lines, the first outsourcing ceramic fireproof＝fire-proof composite band and halogen-free and low-smoke flame-retardant polyolefin insulating barrier; Wherein, the first ceramic fireproof＝fire-proof composite band is wrapped outer in conductor lines, and it is outer that the halogen-free and low-smoke flame-retardant polyolefin insulating barrier is extruded in the first outsourcing ceramic fireproof＝fire-proof composite band.
Outer wrapped the second ceramic fireproof＝fire-proof composite band of heart yearn, fill inorganic fillings between heart yearn and the heart yearn and between heart yearn and the second ceramic fireproof＝fire-proof composite band, the skin of the second ceramic fireproof＝fire-proof composite band extrudes halogen-free and low-smoke flame-retardant polyolefin sheathed.
The utility model compared with prior art beneficial effect is: it is high that this cable has a fire resistance, waterproof, moistureproof, do not absorb water, good mechanical property, environmental protection, the advantage that cost is low.
