Description
Technical Field
The utility model relates to the technical field of cables, in particular to a cable with good corrosion resistance used in a tunnel.
Background
A cable is a power or signal transmission device, and is generally composed of several wires or groups of wires. The cable all need be used to the occasion that needs to popularize at electric power, and different occasions are also different to the performance demand of cable, and if the tunnel is many moist, ordinary cable laying in the tunnel on the market is corroded very easily, greatly reduced life, and need invest too much manpower and materials and maintain, wait urgently to improve the cable conductor that uses in the tunnel.
SUMMERY OF THE UTILITY MODEL
Based on at least one of the technical problems, the utility model provides a novel cable with good corrosion resistance in a tunnel, and the cable has the advantages of reasonable whole structure design, good corrosion resistance and long service life.
In view of the above, the present invention provides a novel cable with good corrosion resistance for use in a tunnel, comprising: the cable comprises an insulated cable fiber core, a first sheath, a first anti-corrosion layer, a first insulating layer, a first waterproof layer, a buffer layer, a second waterproof layer, a second anti-corrosion layer, a second insulating layer and a second sheath which are sequentially arranged from inside to outside.
In the above technical solution, preferably, the first sheath is a soft plastic sheath, and the second sheath is a hard plastic sheath.
In the above technical solution, preferably, a plurality of wear strips are uniformly distributed on the outer surface of the second sheath.
In the above technical solution, preferably, the thickness of the second corrosion prevention layer is larger than the thickness of the first corrosion prevention layer.
Through above technical scheme, the outside parcel in proper order of the limit cable sinle silk of cable has first sheath, first anti-corrosion coating, the first insulating layer, first waterproof layer, the buffer layer, the second waterproof layer, the second anti-corrosion coating, the second insulating layer, the second sheath, wherein, first sheath is soft plastics, the second sheath is the duroplasts, through protecting layer upon layer, avoid the tunnel environment to the corruption influence of cable in the at utmost, make the cable have better corrosion protection ability, the surface of second sheath still is provided with wear strip in addition, increase the wearability of cable sheath, and then effectively avoid the sheath to be caused the corruption to inside cable core after being worn and torn, whole structural design is reasonable, under the prerequisite of guaranteeing that the cable has better corrosion resistance, the life of cable has been prolonged greatly.

As shown in fig. 1, a cable 10 having excellent corrosion resistance used in a tunnel includes: the cable comprises an insulated cable fiber core 11, a first sheath 12, a first anti-corrosion layer 13, a first insulating layer 14, a first waterproof layer 15, a buffer layer 16, a second waterproof layer 17, a second anti-corrosion layer 18, a second insulating layer 19 and a second sheath 20 which are sequentially arranged from inside to outside.
Further, the first sheath 12 is a soft plastic sheath and the second sheath 20 is a hard plastic sheath.
Further, a plurality of wear strips 21 are distributed on the outer surface of the second sheath 20.
Further, the thickness of the second corrosion prevention layer 18 is larger than the thickness of the first corrosion prevention layer 13.
The outside parcel in proper order of the absolute limit cable sinle silk of cable has first sheath, first anti-corrosion coating, the first insulating layer, first waterproof layer, the buffer layer, the second waterproof layer, the second anti-corrosion coating, the second insulating layer, the second sheath, wherein, first sheath is soft plastics, the second sheath is the duroplasts, through protecting layer upon layer, avoid the tunnel environment to the corruption influence of cable in the at utmost, make the cable have better corrosion protection ability, the surface of second sheath still is provided with wear resistant strip in addition, increase the wearability of cable sheath, and then effectively avoid the sheath to cause the corruption to inside cable core after being worn and torn, whole structural design is reasonable, under the prerequisite of guaranteeing that the cable has better corrosion resistance, the life of cable has been prolonged greatly.
The present invention has been described in terms of the preferred embodiment, but it is not limited thereto, and various modifications and changes will be apparent to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
