Abstract
The utility model relates to a theftproof cable, comprising an aluminum wire stranded conductive body, a PVC insulating layer with high electric property, an inner sheath, a double-layer galvanized steel belt armour, and a PVC outer sheath. The aluminum wire stranded conductive body is arranged in the PVC insulating layer with high electric property to form insulating wire cores. The insulating wire cores are stranded to form a cable core. The inner sheath, the double-layer galvanized steel belt armour and the PVC outer sheath are orderly arranged outside the cable core. A zincification high-carbon steel wire is added to the center of the aluminum wire stranded conductive body, and a copper belt shielding layer is added outside the cable core and inside the inner sheath. The electric appliance circuit of a theftproof device can be arranged between the copper belt shielding layer and the double-layer galvanized steel belt armour. The theftproof cable had strong theftproof property.
Description
The utility model relates to this technical field of cable, particularly a kind of antitheft cable.
The existing cable that is used for the distribution network of the open-air electric pump in oil field generally is made up of aluminum steel stranded conductor, high electrically PVC insulating barrier, inner sheath, double-deck zinc-plated steel-tape armouring, PVC oversheath.Lack theftproof performance, be easy to be cut, influence field produces by the lawless person robber.
The utility model provides a kind of antitheft cable at above-mentioned the deficiencies in the prior art part, in this cable the alarm electric loop can be installed, and installs zinc-plated high-carbon steel wire additional at aluminum steel stranded conductor center, has stronger anti-theft.
The utility model is achieved through the following technical solutions: this antitheft cable, comprise the aluminum steel stranded conductor, high electrically PVC insulating barrier, inner sheath, double-deck zinc-plated steel-tape armouring, the PVC oversheath, the aluminum steel stranded conductor is positioned at high electrically PVC insulating barrier, form insulated wire cores, insulated wire cores is twisted into cable core, inner sheath, double-deck zinc-plated steel-tape armouring, the PVC oversheath is positioned at outside the cable core successively, increase by a zinc-plated high-carbon steel wire at the center of aluminum steel stranded conductor, increase by a copper strips screen in the outer inner sheath of cable core, between screen and double-deck zinc-plated steel-tape armouring, the alarm electric loop can be installed.When this antitheft cable is cut, be difficult for being cut off, and the anti-theft circuit in it can be reported to the police.
The utility model compared with prior art has following advantage: this antitheft cable increases by a zinc-plated high-carbon steel wire at the center of aluminum steel stranded conductor, increases by a copper strips screen in the outer inner sheath of cable core, can increase the fastness of antitheft cable, is difficult for being cut.Between screen and double-deck zinc-plated steel-tape armouring, the alarm electric loop can be installed, can report to the police automatically when being cut.
Accompanying drawing 1 is the generalized section of antitheft cable.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail: this antitheft cable, comprise aluminum steel stranded conductor 1, high electrically PVC insulating barrier 2, inner sheath 3, double-deck zinc-plated steel-tape armouring 4, PVC oversheath 5, aluminum steel stranded conductor 1 is positioned at high electrically PVC insulating barrier 2, form insulated wire cores, insulated wire cores is twisted into cable core, inner sheath 3, double-deck zinc-plated steel-tape armouring 4, PVC oversheath 5 is positioned at outside the cable core successively, increase by a zinc-plated high-carbon steel wire 6 at the center of aluminum steel stranded conductor 1, increase by a copper strips screen 7 in the outer inner sheath of cable core, between screen 7 and double-deck zinc-plated steel-tape armouring layer 4, the alarm electric loop can be installed.During manufacturing, aluminum steel stranded conductor 1 generally is that six roots of sensation diameter is arranged is stranded the forming of round aluminum steel of 2.8mm, and a zinc-plated high-carbon steel wire 6 of increase is placed on the center of the six roots of sensation circle aluminum steel when stranded.Crack, cable core limit can adopt non-absorbent material to fill rounding, and wrapped with PVC band two plies.Copper strips screen 7 adopts the thick soft copper band of 0.1mm overlapping wrapped.This antitheft cable has stronger anti-theft when using.
Claims (1)
1, a kind of antitheft cable, comprise aluminum steel stranded conductor, high electrically PVC insulating barrier, inner sheath, double-deck zinc-plated steel-tape armouring, PVC oversheath, the aluminum steel stranded conductor is positioned at high electrically PVC insulating barrier, form insulated wire cores, insulated wire cores is twisted into cable core, inner sheath, double-deck zinc-plated steel-tape armouring, PVC oversheath are positioned at outside the cable core successively, it is characterized in that increasing a zinc-plated high-carbon steel wire at the center of aluminum steel stranded conductor, increase by a copper strips screen in the outer inner sheath of cable core, between screen and double-deck zinc-plated steel-tape armouring layer, the alarm electric loop can be installed.
