Shielded layer A, the shielded layer B is tinned copper wire.

The waterstop is non-hygroscopic non-woven fabrics.

The restrictive coating is fluoroplastics.

The utility model has the following beneficial effects: the utility model encounters the case where high temperature, corrosion while Halogen fire resisting Under, it can effectively improve the operational safety degree of equipment, reduce cost and improve benefit, safety and environmental protection.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Wherein: 1 being conductor, 2 be insulating layer, 3 be shielded layer A, 4 be waterstop, 5 be refractory material, 6 be liner layer, 7 be Shielded layer B, 8 are restrictive coating.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings.

A kind of high efficiency smart environment-friendly cable, including it is conductor 1, insulating layer 2, shielded layer A3, waterstop 4, refractory material 5, interior Lining 6, shielded layer B7, restrictive coating 8, conductor 1 is evenly distributed in the waterstop 4, and the conductor 1 is that tinned copper wire twists It closes, insulating layer 2 is extruded with outside the conductor 1, and insulating layer 2 is crosslinked polyethylene, is woven with outside the insulating layer 2 Refractory material 5 is filled in gap in the outer waterstop 4 of shielded layer A3, the shielded layer A3, the refractory material 5 is resistance to Fiery mica tape, the waterstop 4 are extruded with liner layer 6 outside, shielded layer B7, the screen are woven with outside the liner layer 6 It covers a layer B7 and is coated with restrictive coating 8.

Shielded layer A3, the shielded layer B7 is tinned copper wire.

The waterstop 4 is non-hygroscopic non-woven fabrics.

The restrictive coating 8 is fluoroplastics.

1 any surface finish of conductor, it is close, without greasy dirt, the burr of not damaged insulation, sharp edge, protrusion and the monofilament of fracture；Conductor 1 is twisted by tinned copper wire.

Refractory material 5 is wrapped using fire-resistant isinglass belt double-layer overlapping.

Insulating layer 2 uses and extrudes technique, it is ensured that insulated wire cores color separation is uniformly, unanimously；It is clear that cable production line is equipped with Insulation Material Clean storehouse (container), then using hopper is automatically drawn into, guarantee insulation cleannes, drying property, to guarantee the quality of product.Insulating layer 2 use XLPE, and insulation thickness average value is not less than regulation nominal value, and any point insulating thinnest point is not less than the 90%- of nominal value 0.1mm；Insulating layer is tightly attached on conductor, and cross section must not have the visible impurity of eyesight, bubble, the lump not being plasticized, burnt material, The defects of sand holes.

It is filled in cable conductor gap using with fire-retardant and non-hygroscopic refractory material 5, and keeps stranding shape Rounding；The out-of-roundness of stranding is not more than 10%；

Cable out-of-roundness=(cable maximum outside diameter-cable minimum outer diameter)/cable maximum outside diameter × 100%.

4 material of waterstop uses non-hygroscopic non-woven fabrics；Wrapped one layer or two layers of eclipsed form, Duplication is not less than 15%.

Liner layer 6 uses and extrudes Halogen material water-proof material.

Shielded layer uses proof copper-wire braided shielding construction, and single braiding copper wire is 0.2mm, and braiding number of spindles is 24 ~ 32 ingots, and silk For radical depending on section, count is not less than 80%.

8 material of restrictive coating uses fluoroplastics (F46), and any point minimum thickness is not less than the 80%-0.2mm of nominal value；Sheath Layer 8 should be closely covered on cable body, surface must be plasticized good, rounding, without the visible impurity of eyesight, bubble, sand holes the defects of.
