Design principle:
(1) conductor flexibility and resistance to twisting energy are improved
Conductor flexibility and resistance to twisting can depend primarily on the filament diameter of cable conductor and the synnema of conductor and the knot twisted again
Structure.In order to enable conductor to have flexibility and resistance to twisting, conductor filament diameter is designed to lead between five classes and six classes in the present invention
Filament diameter between body can both guarantee the flexibility of cable conductor, while can guarantee that conductor has certain stretching resistance.
The resistance to twisting of conductor can depend primarily on whether cable conductor is twisted closely, in the case that conductor strand is loose,
Conductor deformation is larger when bending, is easy to appear between monofilament and displacement, friction phenomenon occurs, and long-term displacement deformation, monofilament is easy
There is monofilament, and then leads to entire conductor fracture of wire, it is close for conductor strand, using twisted when reducing synnema and twisting again
Pitch ratio.Five class conductor synnema pitch ratio general control of common cable twists pitch general control within 30 times of synnema outer diameters again
It is twisted within outer diameter again at 14 times.In order to improve the resistance to twisting energy of cable conductor, synnema pitch multiple proportions is controlled in 18 times of synnema outer diameters
Within, pitch general control is twisted again to be twisted within outer diameter again at 10 times.
By conductor filament diameter, synnema pitch multiple proportions and the control of strand pitch multiple proportions again, keep conductor structure more stable,
Tightness degree is high, and outer diameter is small, and conductor wire core pliability is good, and resistance to twisting can be excellent.
(2) explosion-proof performance.
Blast resistance construction of the invention using:
The wrapped three layers of carbon cloth band in 2.1 every core surfaces；
The wrapped one layer of carbon cloth band of 2.2 cable surfaces, extrudes one layer of nylon protective layer, is protecting after extruding protective layer after wrapped
The braiding layer of one layer of aramid yarn of sheath surface all standing, further around carbon cloth band of double-baging after braiding layer；
After the total stranding of 2.3 cable cores, one layer of high intensity is woven in the wrapped three layers of carbon cloth band in stranding cable core surface, then all standing
Aramid yarn；
2.4 sheaths use double-layer composite sheath
Duplex sheath, inside and outside shield centre are equipped with steel wire protective layer, material selection low carbon stainless steel steel wire, on the one hand, steel wire is very soft
Soft, so that the bending radius of cable is small, flexibility influences small；On the other hand, stainless steel steel wire is not allowed perishable, is used for a long time not
Protective performance can be influenced since dampness causes steel wire to get rusty.
(3) optical fiber is compound
It is filled among cable core using reinforced saddle item in the present invention, the power wire core of cable, wire core and optical fiber are arranged in saddle
Shape gap, the section of cable conductor be it is full symmetric, cable roundness is improved, and ensure that cable overall structure is steady
It is qualitative, reduce the use of cable filling, reduces cable weight and outer diameter, increase the resistance to dragging ability of entirety of cable.
