Drawings
Fig. 1 is a schematic structural view of a moistureproof fireproof flame-retardant cable of the present utility model.
As shown in the figure:
1. a cable core; 2. an insulating layer; 3. a moisture barrier; 4. a refractory layer; 5. a buffer layer; 6. a reinforcing layer; 7. a protective layer; 8. a non-woven fabric layer.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The utility model provides a moistureproof and fireproof flame-retardant cable, which comprises a cable core 1, an insulating layer 2, a moistureproof layer 3, a fireproof layer 4, a buffer layer 5, a reinforcing layer 6 and a protective layer 7, and is characterized in that: the insulating layer 2 is located the cable core 1 outside, prevents the electric leakage problem from the source, and the atress ability of insulating layer 2 is relatively poor simultaneously, also can be protected, dampproof course 3 is located the insulating layer 2 outside, and insulating layer 2 outward measures dampproof course 3, even under the circumstances that insulating layer 2 breaks, also mode water that can be fine gets into cable core 1, flame retardant coating 4 is located the dampproof course 3 outside, buffer layer 5 is located the flame retardant coating 4 outside, enhancement layer 6 is located the buffer layer 5 outside, inoxidizing coating 7 is located the enhancement layer 6 outside.
Further, the insulating layer 2 is made of polyvinyl chloride, and the polyvinyl chloride can have a good insulating effect.
Further, the moisture-proof layer 2 is made of water-blocking tape, and the water-blocking tape can prevent water from penetrating, so that a moisture-proof effect is achieved.
Further, the buffer layer 5 is made of buffer cotton, and the buffer cotton can play a role in buffering.
Further, the reinforcing layer 6 is made of steel wire mesh, and the strength of the cable can be reinforced by the arrangement of the steel wire mesh.
Further, the protective layer 7 is made of polyethylene, and the polyethylene at the outermost side not only plays a role in protection, but also plays a certain role in flame retardance, so that the fireproof effect of the cable is improved.
Further, the non-woven fabric layer 8 is arranged outside the cable core 1, the cost of the non-woven fabric is high, the chemical structure is stable, and the cable core can be well protected.
Working principle:
during operation, insulating layer 2 that polyvinyl chloride material was made has played insulating effect to cable core 1, dampproofing and waterproofing's effect has been played by dampproofing layer 3 that the water blocking tape was constituteed, flame retardant coating 4 then can improve the fire resistance of cable, its fire prevention effect has been promoted to a certain extent, and inoxidizing coating 7 is made by the polyethylene, not only played the effect of protection, also have fire-retardant performance, can further improve the effect of cable fire prevention, the enhancement layer 6 that the wire net is constituteed makes the intensity of cable higher, buffer layer 5 that the buffer cotton is constituteed then has strengthened the buffering effect of cable, can further improve the protection effect of cable.
While the utility model has been described with reference to the preferred embodiments, it is not limited thereto, and various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
