Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, a conductor 1, a foaming insulator 2, a polyester 3, a drainage wire 6, a low-smoke halogen-free flame-retardant inner sheath 7 and a copper wire 8 are wrapped, and an aluminum foil 4, a shielding wire 5 and a flame-retardant low-smoke halogen-free outer sheath 8 are woven.

Detailed Description

Low electric capacity cable is used in measurement system connection, including seven strands or stranded soft copper conductor 1, seven strands or stranded soft copper conductor 1 are provided with foaming polyethylene insulating layer 2 outward and form the sinle silk, two the sinle silk peripheral hardware polyester winds package 3 and forms a unit, unit and drainage wire 5 are outer to be set up aluminium foil shielding 4 formation cable cores, and a plurality of cable cores are outer to be set up low smoke and zero halogen fire-retardant

inner sheath

6, 6 outer copper wires of low smoke and zero halogen fire-retardant inner sheath are woven 7, 7 outer fire-retardant type low smoke and zero halogen oversheath 8 are woven to the copper wire.

Furthermore, a tinned drainage wire is arranged in the copper wire weaving 7.

Furthermore, seven cable cores are arranged.

The following is a further explanation of the present invention to better understand the present invention: the utility model discloses low electric capacity cable is used in measurement system connection is special for cooperation current measurement system connects usefulness.
