Abstract
The utility model belongs to the cable technique field, in particular to an electric meter telemetry cable which is characterized in that: the utility model comprises a conductor (1); a shielding layer (2) is arranged at the outside of the conductor (1); a PVC outer sheath A (3), a double-layer steel belt wrap (4) and a PVC outer sheath B (5) are respectively disposed at the outside of the shielding layer (2); and the double-layer steel belt wrap (4) is positioned between the PVC outer sheath A (3) and the PVC outer sheath B (5). The utility model has advantages of excellent electrical performance, high insulation resistance, small operating capacitance and good pliability, and can fully improve the signal transmission quality.
Description
Affiliated technical field
The utility model belongs to the cable technology field, particularly a kind of ammeter distant reading type cable.
Background technology
At present, still there is not the special-purpose cable product that designs for kilowatt meter reading-out system on the market.The already used substitute that is because of mutual capacitance does not reach requirement, causes pulse signal distortion in service, influences the monitoring system work quality.
Summary of the invention
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, good electric property, and the insulation resistance height, mutual capacitance is little, and flexibility can fully improve the ammeter telemetry cable of signal transmission quality well.
Technical solution of the present utility model can realize according to following mode:
A kind of ammeter telemetry cable, it contains: conductor; Outside at described conductor is furnished with screen; Be furnished with PVC oversheath A, wrapped, the PVC oversheath B of double-deck steel band respectively in the outside of described screen; Described double-deck steel band is wrapped to be placed between PVC oversheath A and the PVC oversheath B.
The twisted copper wires that conductor described in the utility model is furnished with the low-k plastic insulating layer by the outside constitutes.
Screen described in the utility model contains the polyester bed course and metal screen layer constitutes.
Twisted copper wires described in the utility model can be 48.
The utility model is simple in structure, good electric property, the insulation resistance height, mutual capacitance is little, and conductor is made by strands, and flexibility is good, metallic barrier can improve signal transfer quality, double-deck steel-tape armouring makes product that the ability of anti-mechanical external force preferably be arranged, and both can be used for burying ground, also can be used for hanging in the open.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
As shown in the figure, a kind of ammeter telemetry cable, it contains: conductor 1; Is furnished with screen 2 in the outside of described conductor 1; Is furnished with wrapped 4, the PVC oversheath B5 of PVC oversheath A3, double-deck steel band respectively in the outside of described screen 2; Described double-deck steel band wrapped 4 places between PVC oversheath A3 and the PVC oversheath B5.The twisted copper wires that described conductor 1 is furnished with the low-k plastic insulating layer by the outside constitutes.Described screen 2 contains the polyester bed course and metal screen layer constitutes.Described twisted copper wires is 48.
The utility model conductor 1 is by 48 stranded forming of fine copper wire.Insulation is adopted the insulating material of low-k to extrude and is formed, and core is used respectively red, yellow, green, Bai Si kind color differentiating is with convenient use.Make barrier layer with metal wire knitted behind the stranding, extrude inner sheath on it, wrapped steel band extrudes the PVC oversheath again.
Cable is used for the 300/500V electric pressure.Product type is DYYVP
22, cross section 0.5～2.5mm
2Between, several 2～7 cores of core.
The main performance of cable: mutual capacitance is not more than 0.1 microfarad/kilometer, is not less than 1000 megaohm/kilometers during 20 ℃ of insulation resistances, and ac voltage withstanding 1000V passed through in 3 minutes.
