Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Fig.1, is a kind of control cable disclosed by the utility model, including conductor 1, sheath 2, rubber core 3 and U
The structures such as shape metallic sheath 4.
Rubber core 3 is located at the center of cable, and multiple insertions being arranged along its length are offered on outer wall
Slot 31, embedded groove 31 are uniformly distributed, and opening direction is along the radial direction of rubber core 3, and opening width is equal to groove depth, the number of conductor 1
Amount is identical as the quantity of embedded groove 31, is embedded into embedded groove 31.U-shaped gold is provided between conductor 1 and the inner wall of embedded groove 31
Belong to set 4, for wrapping up and supporting conductor 1, the opening direction of U-shaped metallic sheath 4 is identical as the opening direction of embedded groove 31, and pastes
It closes on the wall of embedded groove 31.Two sides of U-shaped metallic sheath 4 are stretched out from the outward opening side of embedded groove 31, and to two lateral bendings
Folding forms edge 41, and the section of edge 41 is arc-shaped, is fitted in it on outer wall of rubber core 3, outside rubber core 3
Wall is also arc-shaped.Edge 41 extends close to the outer wall of rubber core 3, and supports with the edge of another U-shaped metallic sheath 4 41
It connects, makes to form a sealing ring between U-shaped metallic sheath 4.
The inner wall of sheath 2 is provided with steel band 5, and steel band 5 is for being supported sheath 2.When erecting cable, the self weight of cable
Longitudinal shear is generated to conductor 1, the case where cable generates deformation is reduced by the mechanical strength of steel band 5.Steel band 5 will be cut
After power, for steel band 5 by stress transfer to rubber core 3 and U-shaped metallic sheath 4, rubber core 3 plays a supporting role to cable,
The mechanical strength of cable is further ensured that by the mechanical strength of U-shaped metallic sheath 4.
There are gaps for conductor 1 and the insulated part in outside, therefore in gap section the feelings of shelf depreciation can occur for conductor 1
Condition, therefore in the position of 1 shelf depreciation of conductor, the insulated part in 1 outside of conductor is easy electric discharge and temperature increases.Therefore in order to avoid
1 surface of conductor is provided with shielded layer 6 in the outside of conductor 1 due to the gap with insulated part and the case where shelf depreciation,
Shielded layer 6 is made of yellow gold, and the surface equipotential of shielded layer 6 and conductor 1, shielded layer 6 is bonded with the insulated part in outside,
To reduce conductor 1 the case where gap is discharged.
The outside of shielded layer 6 is provided with fiberglass insulation 7, is bonded between shielded layer 6 and fiberglass insulation 7.
The case where fiberglass insulation 7 has good insulating properties, and sheath 2 can be made to charge to avoid the electric current in conductor 1, glass fibers
Tieing up insulating layer 7 also has good mechanical strength, so that the self weight for reducing cable damages the shearing of conductor 1.
When 1 long-time of conductor is in overload operation, the high current in conductor 1 makes fiberglass insulation 7 be in high temperature
State, therefore the case where fiberglass insulation 7 is easy to happen burning, therefore burn in order to avoid fiberglass insulation 7
Situation, therefore the outside of fiberglass insulation 7 is provided with modified flame-retardant polypropylene layer 8.Modified flame-retardant polypropylene layer 8 is by poly- third
Alkene is added fire retardant and is process, and modified flame-retardant polypropylene layer 8 has good anti-flammability, so that modified flame-retardant polypropylene layer 8 hinders
The case where fiberglass insulation 7 burns is stopped, and then has reduced and the sheath 2 on the outside of cable is caused to burn and cause conductor 1 exposed
The case where.
The mechanical strength of cable in order to further increase, thus third is additionally provided in the outside of modified flame-retardant polypropylene layer 8
Olefin(e) acid ester gum layer 9.Acrylate glue-line 9 has the characteristics that high-intensitive, corrosion-resistant and impact-resistant, and acrylate glue-line 9 is wrapped up
In the outside of cable, influence of the stress to conducting wire, but also acrylic acid is not only can be effectively reduced in the intensity of acrylate glue-line 9
The corrosion resistance characteristic of ester gum layer 9 can reduce corrosion of the substance (such as acid rain) of extraneous corrosion to cable.
Crosslinked polyethylene enhancement layer 10 is provided on the outside of acrylate glue-line 9.Since the density of crosslinked polyethylene is small, thus
When cable is set up over long distances, the self weight of cable is small, so that damage of the shearing to cable for the self weight that cable is subject to is reduced, in addition,
The shearing of the high mechanical strength of crosslinked polyethylene, cable self weight is not easy to cause crackle on crosslinked polyethylene surface.
The outside of crosslinked polyethylene enhancement layer 10 is provided with aramid fiber layer of cloth 11.The intensity of aramid fiber layer of cloth 11 is high,
When in 11 deformation range of aramid fiber layer of cloth, deformation when aramid fiber layer of cloth 11 meets with stresses is small, and aryl fiber cloth has
Have the characteristics that heat resistance is high, can not only further enhance the mechanical strength of cable, the variation pair of ambient temperature can also be reduced
The influence of cable.
Polyvinyl chloride layer 12 is provided on the inner wall of steel band 5.Polyvinyl chloride ductility and toughness with higher, can subtract
The case where few cable self weight causes 2 face crack of sheath, meanwhile, polyvinyl chloride has very high anticorrosion properties, is further reduced
Cable causes cable surface to occur corroding and the case where crackle due to extraneous corrosive deposit.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
