Abstract
The utility model discloses a kind of environment-friendly cable, the skin of inner covering adopts S type lock armo, the outside parcel low smoke and zero halogen environmental protection cover of described S type lock armo, the inner side of S type lock armo layer is provided with conductor, conductor adopts special-shaped single line shaping mutually stranded by pretwist, described conductor is wrapped with insulating barrier and forms cable core, and described cable core gap Halogen gasket for packing is filled.The conductor diameter that the technical program adopts very also has stranded conductor softness, the advantage that flexible, structural stability is good close to solid conductor, the consumption of insulation, filling, twining package tape, armouring and sheath material can also be reduced simultaneously, reduce combustible object about 2%, improve the environmental-protecting performance of cable further.
Description
Technical field:
The utility model discloses a kind of cable, is specially adapted to power cable field uses.
Background technology:
Now traditional power cable, mostly adopt circular single line stranded conductor, the activity coefficient of stranded conductor is 0.75, after pressing, activity coefficient also only reaches 0.82-0.92, therefore cause conductor diameter bigger than normal, add the consumption of insulation, filling, armouring and sheath material, thus increase production cost and do not reach the object of environmental protection; And common armoured cable sheath adopts PVC material, containing halogen in material, produce toxic gas during burning, the amount of being fuming is large, and light transmittance is low, not only causes environmental pollution, but also the rescue work of restriction scene of fire.
Summary of the invention
Task of the present utility model proposes a kind of reduction outside diameter of cable, reduces the consumption of organic material, alleviate the infringement caused when fire occurs, energy-conservation a kind of environment-friendly cable.
Task of the present utility model completes like this, a kind of environment-friendly cable, it is characterized in that: the skin of inner covering adopts S type lock armo, the outside parcel low smoke and zero halogen environmental protection cover of described S type lock armo, the inner side of S type lock armo layer is provided with conductor, conductor adopts special-shaped single line shaping mutually stranded by pretwist, and described conductor is wrapped with insulating barrier and forms cable core, and described cable core gap Halogen gasket for packing is filled.Described insulating barrier adopts cross-linked polyethylene insulating material to make.That what described special-shaped conductor adopted is is T-shaped/and SZ type.
The utility model has following effect: the conductor diameter that the technical program adopts very also has stranded conductor softness, the advantage that flexible, structural stability is good close to solid conductor, the consumption of insulation, filling, twining package tape, armouring and sheath material can also be reduced simultaneously, reduce combustible object about 2%, improve the environmental-protecting performance of cable further.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model SZ type conductor cable; Fig. 2 is the structural representation of the T-shaped conductor cable of the utility model; Fig. 3 is the structural representation of metal tape.
Drawing illustrates: 1, conductor, 2, insulating barrier, 3, packed layer, 4, inner covering, 5, metal tape, 6, protective sleeve.
Embodiment:
The conductor shape that the technical program adopts is that SZ type/and T-shaped single line are stranded, gap between single line reduces further than common compact conductor, activity coefficient reaches as high as more than 0.98, external diameter reduces about 3% than common compact conductor, sheath material adopts halogen-free and low-smoke flame-retardant polyolefin sheathed, all composition materials of cable do not have halogen, decrease the generation of toxic gas, and the acid mist simultaneously avoiding hydrogen chloride and steam formation causes " secondary disaster ".Metal tape adopts aluminium alloy lock armo to replace traditional double-deck steel-tape armouring, reduce cable weight, cable bend performance is better than ordinary steel belts sheathed structure, the Cable Bending Radius of ordinary construction is 15 times of the outside diameter of cable, linkage armored cable only has 7 times of the outside diameter of cable, and corresponding decreasing lays required space.
Embodiment one, as shown in Figure 1, one deck protective sleeve 6 is wrapped up in the outside of inner covering 4 and metal tape 5, and metal tape 5 adopts S type lock armo structure, all linked with one another.Described inner covering 4 and the inside of metal tape 5 are provided with conductor 1, described conductor 1 adopts that SZ type type single line is stranded to be formed, high-speed and continuous deformation technology is adopted to draw shaping, mutually twisted together by the shaping stranded technology of pretwist, conductor is wrapped with insulating barrier 2 and forms cable core, described cable core gap is packed layer 3, described packed layer adopts Halogen gasket for packing, described metal tape 5 adopts " S type " lock armo, all linked with one another, employing lock armo cable only has 7 times of the outside diameter of cable, and corresponding decreasing lays required space.
Embodiment two; as shown in Figure 2, conductor 1 adopts that T-shaped single line is stranded to be formed, and adopts high-speed and continuous deformation technology to draw shaping; mutually twisted together by the shaping stranded technology of pretwist; conductor is wrapped with insulating barrier 2 and forms cable core, and the inside of inner covering 4 and metal tape 5 is provided with cable core, and the gap of cable core is packed layer 3; packed layer adopts Halogen gasket for packing; described metal tape adopts " S type " lock armo, and all linked with one another, one deck protective sleeve 6 is wrapped up in the outside of described inner covering and metal tape 5.
This cable reduces the consumption of organic material with compact structure, reduces the outside diameter of cable, ensure that the low consumption of cable, energy saving standard performance.
