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 multiple strand
Structure.In order to enable conductor to have flexibility and resistance to twisting, conductor filament diameter is designed between five classes in the utility model
And six filament diameters between class conductor, it can both guarantee the flexibility of cable conductor, while it is certain to guarantee that conductor has
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.
The blast resistance construction of the utility model 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, after extruding protective layer after wrapped
Further around carbon cloth band of double-baging after the braiding layer of one layer of aramid yarn of protective layer all standing, braiding layer；
After the total stranding of 2.3 cable cores, one layer of height is woven in the wrapped three layers of carbon cloth band in stranding cable core surface, then all standing
The aramid yarn of intensity；
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
Very 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, makes for a long time
With steel wire will not being caused to get rusty influence protective performance due to dampness.
(3) optical fiber is compound
It is filled among cable core using reinforced saddle item in the utility model, the power wire core of cable, wire core and optical fiber
Be arranged in saddle type gap, the section of cable conductor be it is full symmetric, cable roundness is improved, and ensure that cable is whole
Body structural stability reduces the use of cable filling, reduces cable weight and outer diameter, increase the resistance to dragging of entirety of cable
Ability.
