Abstract
The utility model discloses an environmental-protection type waterproof double-shielding control cable which comprises a plurality of insulating wire cores, wherein a copper wire knitting sub-shielding layer is wrapped outside each insulating wire core; after being twisted, the plurality of insulating wire cores are wrapped with taped coverings; water resisting yarns are filled in the taped coverings in a manner of extruding; a low-smoke halogen-free polyolefin internal protective sleeve is wrapped outside each taped covering; and a head copper belt shielding layer, a polyester belt, an amoure layer and an external protective layer are sequentially wrapped outside each internal protective sleeve. According to the environmental-protection type waterproof double-shielding control cable, the double-layer shielding design is adopted, which effectively improves the interference resistance of a control cable; and moreover, the water resisting yarn which has good effect of resisting water is filled, so that the waterproof performance of the control cable can be greatly improved; the environmental protection low-smoke halogen-free polyolefin material is served as the internal protective sleeve, thereby, the dense smoke and corrosive gas cannot be generated once burning occurred, and as a result, the work of rescuing can be carried out conveniently.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of environment-friendly type waterproof double shield control cable.
Background technology
Existing control cable mostly is by core and is coated on the outer field screen of core and the insulating sleeve layer constitutes; High temperature resistant, the water resistance and the interference free performance of this type of cable are all undesirable; In use there is potential safety hazard in the water resistance difference, and oversheath mostly adopts the insulating material of Halogen to process, when high temperature and fire take place; Not only can produce a large amount of dense smoke; And can produce the very strong poisonous hydrogen halide of corrosivity with " secondary disaster ", jeopardize personnel's life, harm equipment and pollutant atmosphere.Therefore these performances that improve cable seem particularly necessary.
The utility model content
The purpose of the utility model provides a kind of environment-friendly type waterproof double shield control cable, and is not good with high temperature resistant, the waterproof and the interference free performance that solve control cable in the prior art, in use has the problem of potential safety hazard.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of environment-friendly type waterproof double shield control cable; It is characterized in that: include several insulated wire cores; Every insulated core is coated with copper wire braiding sub-shield, is surrounded with lapping layer after several insulated wire cores are stranded, extrudes in the said lapping layer to be filled with group water yarn; Said lapping layer is coated with the low-smoke halogen-free polyolefin inner sheath, and said inner sheath is coated with the total screen of copper strips, polyester belt, armour and oversheath outward successively.
Described a kind of environment-friendly type waterproof double shield control cable is characterized in that: said lapping layer adopts the fluoroplastics material to process.
Described a kind of environment-friendly type waterproof double shield control cable, it is characterized in that: said armour is a steel-tape armouring.
Described a kind of environment-friendly type waterproof double shield control cable is characterized in that: said oversheath adopts silicon rubber to process.
The beneficial effect of the utility model is:
The utility model adopts the double layer screen design; Promoted the interference free performance of control cable effectively; And adopt the good group water yarn of block-water effect to fill the most, make the water resistance of control cable significantly promote, the low-smoke halogen-free polyolefin material that adopts environmental protection is as inner sheath;, burning can not discharge dense smoke and corrosive gas when taking place; The carrying out that is of value to rescue work, the utility model also have good resistance to elevated temperatures and stronger mechanical performance, and environment for use is had stronger adaptability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model includes several insulated wire cores 1; Every insulated core 1 is coated with copper wire braiding sub-shield 2, is surrounded with lapping layer 3 after several insulated wire cores 1 is stranded, extrudes in the lapping layer 3 and is filled with group water yarn 4; Lapping layer 3 is coated with low-smoke halogen-free polyolefin inner sheath 5, and inner sheath 5 is outer to be coated with the total screen of copper strips 6, polyester belt 7, armour 8 and oversheath 9 successively.
Lapping layer 3 adopts the fluoroplastics material to process.Armour 8 is a steel-tape armouring.Oversheath 9 adopts silicon rubber to process.
