Abstract
The utility model discloses an environmental protection type double-shielding control cable which comprises a plurality of insulating wire cores, wherein each insulating wire core is externally wrapped with a copper wire knitting sub-shielding layer and a fireproof layer in sequence; after being twisted, the plurality of insulating wire cores are wrapped with taped coverings; a low-smoke halogen-free polyolefin internal protective sleeve is wrapped outside each taped covering; and a heat insulating layer, a copper belt head shielding layer and an external protective sleeve are sequentially wrapped outside each internal protective sleeve. According to the environmental protection type double-shielding control cable, the design of double-layer head shielding effectively improves the interference resistance of a control cable; the low-smoke halogen-free polyolefin is served as the internal protective sleeve, thereby the dense smoke and the corrosive gas cannot be generated once burning occurred, and high environmental protection performance can be achieved; and meanwhile, the environmental protection type double-shielding control cable has excellent high temperature resistance, excellent oil resistance and excellent corrosion resistance.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of environment-friendly type 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 oil resistant of this type of cable, decay resistance and interference free performance are all undesirable, 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 double shield control cable, with high temperature resistant, the oil resistant that solves control cable in the prior art, corrosion-resistant and interference free performance is relatively poor, and not enough environmental protection, can not reach the problem of instructions for use.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of environment-friendly type 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 and flame retardant coating outward successively; Be surrounded with lapping layer after several insulated wire cores are stranded, said lapping layer is coated with the low-smoke halogen-free polyolefin inner sheath, and said inner sheath is coated with thermal insulation layer, the total screen of copper strips and oversheath outward successively.
Described a kind of environment-friendly type double shield control cable, it is characterized in that: said thermal insulation layer is the aluminium-plastic tape thermal insulation layer.
Described a kind of environment-friendly type double shield control cable is characterized in that: be extruded with silicon rubber in the said lapping layer.
The beneficial effect of the utility model is:
The utility model adopts double-deck total Shielding Design, has effectively promoted the antijamming capability of control cable; Adopt low-smoke halogen-free polyolefin as inner sheath, when burning takes place cable, can not discharge dense smoke and corrosive gas, have good environment protecting, the utility model also has good high temperature resistant, oil resistant, decay resistance simultaneously.
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 outer copper wire braiding sub-shield 2 and flame retardant coating 3 of being coated with successively; Be surrounded with lapping layer 4 after several insulated wire cores 1 is stranded, lapping layer 4 is coated with low-smoke halogen-free polyolefin inner sheath 5, inner sheath 5 outer thermal insulation layer 6, the total screen 7 of copper strips and the oversheaths 8 of being coated with successively.
