Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-3, a novel metal sheath extruded ceramic silicon rubber insulated cable comprises a metal conductor 1, wherein an extruded ceramic silicon rubber insulated layer 2 is arranged on the outer surface of the metal conductor 1, a filling layer 3 is arranged on the outer surface of the extruded ceramic silicon rubber insulated layer 2, and a metal sheath 4 is arranged on the outer side of the outer surface of the filling layer 3;

the ceramic silicon rubber insulating layer 2 is extruded and coated on the metal conductor 1 by adopting an extrusion coating process, so that the ceramic silicon rubber insulating layer 2 and the metal conductor 1 are more tightly coated; the metal conductor 1 can be a single metal wire or a metal wire formed by twisting a plurality of metal wires, and the number of the metal conductors 1 can be single or multiple; the filling layer 3 is inorganic fiber or inorganic tape wrapping and filling, and can also be ceramic silicon rubber for extrusion coating, and the filling layer 3 can be omitted under the condition that the metal conductor 1 is a single metal conductor, so that the filling effect of the filling layer 3 is ensured to be better; the metal sheath 4 can be made of materials such as continuous welding embossing metal, armored metal and extruded metal, a plastic sheath layer is arranged on the outer surface of the metal sheath 4, and the plastic sheath layer can be omitted, so that the fireproof performance, the waterproof performance, the anti-collision extrusion performance and the like of the cable are further enhanced.

It should be noted that, the utility model relates to a novel ceramic silicon rubber insulated cable of metal sheath extrusion package, when using, at first, because of ceramic silicon rubber insulating properties is good, fire behavior is good, there is certain elasticity, adopt the technology cladding of extrusion parcel with ceramic silicon rubber on metallic conductor 1, thereby form ceramic silicon rubber insulating layer 2 of extrusion package, and ensure its cladding on metallic conductor 1, thereby enable ceramic silicon rubber insulating layer 2 of extrusion package, filling layer 3 and metal sheath 4 are closely laminated, the stability of ceramic silicon rubber insulating layer 2 of cable extrusion package has been improved, and metal sheath 4 has better fire behavior, waterproof performance and anticollision extrusion performance etc. comparatively practical.
