FIG. 1 is a schematic cross-sectional structure of the present invention;

fig. 2 is a schematic view of the longitudinal section structure of the present invention.

In the figure: the protective sleeve comprises a first outer protective sleeve 1, a friction layer 2, a second outer protective sleeve 3, a shielding layer 4, a third outer protective sleeve 5, a protective sleeve 6, a lead 7, a filling layer 8 and a reinforcing strip 9.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a low smoke and zero halogen sheath copper core flexible cable of wear-resisting tensile, including first outer lag 1, 1 inner wall fixedly connected with frictional layer 2 of first outer lag, can protect internal function structure to avoid wearing and tearing when outer lag is worn out, the outer lag 3 of 2 inner wall fixedly connected with second of frictional layer, 3 inner wall parcels of the outer lag of second have shielding layer 4, 4 inner wall parcels of shielding layer have the outer lag 5 of third, 5 inside parcels of the outer lag of third have interior protective sheath 6, 6 inner wall parcels of interior protective sheath have wire 7, it has filling layer 8 to fill between lag 5 of third and the interior protective sheath 6.

First outer lag 1, the outer lag 3 of second and the outer lag 5 of third are made by low smoke and zero halogen material, can not produce harmful gas during the burning, and are more environmental protection.

The inner wall and the outer wall of the friction layer 2 are both fixedly connected with reinforcing strips 9, so that the longitudinal tension capability of the cable can be enhanced, and the cable is not easy to break.
