Description

Novel metalloid shielding control cable

Technical field

The utility model relates to control field of cable technology, specifically, more particularly to novel metalloid shielding control electricity Cable.

Background technique

Usually control cable for subway station, computer controlling center, skyscraper building, hotel, TV and Radio Service, The control such as important military installations, monitoring loop and protection circuit connection, when the common metal screen layer of selection controls cable, cable Softness will can not meet requirement, influence the mounting and installation of cable, and metal screen layer higher cost.

Summary of the invention

To solve the above-mentioned problems, the utility model discloses a kind of novel metalloids to shield control cable, shield effectiveness And environmental-protecting performance is very excellent.

The utility model is achieved through the following technical solutions:

Novel metalloid shielding control cable, the cable includes several conductors, and heat curing type polyene is extruded outside the conductor Hydrocarbon insulating layer constitutes insulated wire cores, and the nonmetallic shielding material of one layer of conductivity type is extruded after the insulated wire cores twisted synthesizing cable and constitutes screen Layer is covered, one layer of thermoplastics type's halogen-free and low-smoke flame-retardant polyolefin oversheath is extruded outside the shielded layer.

Compared with prior art, the utility model has the beneficial effects that

The shielded layer of the utility model cable is made of the nonmetallic shielding material of conductivity type, has both met the shielding of cable Demand, and have the advantages that economic and environment-friendly, the shield effectiveness and environmental-protecting performance of cable are very excellent；Oversheath uses thermoplastics type Halogen-free and low-smoke flame-retardant polyolefin sheathed, surface is smooth, good insulation preformance, good mechanical performance, ageing-resistant.

Detailed description of the invention

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

In figure: 1, conductor；2, insulating layer；3, shielded layer；4, oversheath.

Specific embodiment

The present invention will be further described with reference to the accompanying drawing:

Novel metalloid shielding control cable, the cable includes several conductors 1, and it is poly- to extrude heat curing type outside the conductor 1 Alkene insulating layer 2 constitutes insulated wire cores, extrudes the nonmetallic shielding material structure of one layer of conductivity type after the insulated wire cores twisted synthesizing cable At shielded layer 3, one layer of thermoplastics type's halogen-free and low-smoke flame-retardant polyolefin oversheath 4 is extruded outside the shielded layer 3.

As shown in Figure of description Fig. 1, the relative structural properties of this patent are that heat curing type polyolefine material is extruded outside conductor Insulated wire cores are formed, several insulated wire cores twisted synthesizing cables form cable core, one layer of nonmetallic shielding material of conductivity type is extruded outside cable core Shielded layer is formed, one layer of halogen-free and low-smoke flame-retardant polyolefin sheathed material of thermoplastics type is extruded outside shielded layer.

In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair Decorations, should be included in the scope of the claims of the utility model.
