Abstract
The invention discloses an incremental transmission cable which comprises a cable core, a packing layer filled in a gap in the cable core, and an inner protection layer extruded outside the cable core, wherein a first aluminum foil shielding layer is wrapped outside the inner protection layer; a first copper wire shielding layer is formed outside the first aluminum foil shielding layer; a second aluminum foil shielding layer is wrapped outside the first copper wire shielding layer; a second copper wire shielding layer is formed outside the second aluminum foil shielding layer; an outer sheath made from thermoplastic polyurethane (TPU) natural color elastomer materials is extruded outside the second copper wire shielding layer; the cable core is formed by twisting a plurality of control cores; and each control core of the cable core consists of a control core conductor and an insulating medium layer extruded outside the control core conductor. The incremental transmission cable has the characteristics of electromagnetic interference resistance, excellent electrical property, good flexibility, high tensile strength, ruggedness, durability, water resistance, corrosion resistance, low smoke, inflaming retarding, environmental friendliness, and the like.
Description
Technical field
The present invention relates to the power cable field, especially a kind of incremental transmission cable.
Background technology
At present; Flexible drag chain cable structure is single in the prior art, and generation electromagnetic interference in the incremental transmission electric current can be given on every side or equipment of itself brings some problems; Cause the misoperation of equipment and the distortion of data; In addition, its pliability, tensile strength be weak, easy to wear, lack flame-retardant property, acid and alkali-resistance, corrosion-resistant not, around giving miscellaneous equipment with self bring some hidden danger.
Summary of the invention
The technical problem that the present invention will solve provides a kind of anti-electromagnetic interference, electrical property is excellent, flexibility is good, tensile strength is strong, tough durable, etch-proof incremental transmission cable.
A kind of incremental transmission cable of the present invention; It comprises that cable core, the space in cable core are filled with packed layer and outside cable core, extrude sheath; Wrapped first foil shielding layer outside sheath, the braiding first copper wire screen outside first foil shielding layer, wrapped second foil shielding layer outside the first copper wire screen; The establishment second copper wire screen extrudes oversheath outside the second copper wire screen outside second foil shielding layer.
Described cable core is that core is stranded forms by several controls, and its control core is made up of the control line core conductor insulating medium layer outer with being extruded in the control line core conductor.
Described external sheath layer is polyurethane TPU true qualities elastomeric materials.
Beneficial effect of the present invention is:
The present invention is owing to adopt the polyster fibre braid and external sheath layer employing polyurethane TPU true qualities elastomeric material; Can prevent the interference of extraneous forceful electric power magnetic signal; Avoid the distortion of useful signal; Not only possess excellent electric performance, tough durable, and soft, have waterproof, anticorrosion, low cigarette, fire-retardant, environmental protection, characteristic such as nontoxic simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; A kind of enhancing transmission cable of the present invention; It comprises that cable core, the space in cable core are filled with packed layer 3 and outside cable core, extrude sheath 4; Wrapped first foil shielding layer 5 outside sheath 4, the braiding first copper wire screen 6 outside first foil shielding layer 5, wrapped second foil shielding layer 7 outside the first copper wire screen 6; Outside second foil shielding layer 7, work out the second copper wire screen 8, outside the second copper wire screen 8, extrude a kind of oversheath 9 of polyurethane TPU true qualities elastomeric material.Its cable core is that core is stranded forms by several controls, its control core by control line core conductor 1 be extruded in control line core conductor 1 outer insulating medium layer 2 and form.
The invention provides a kind of version and implementation method of incremental transmission cable; The above only is a preferred implementation method of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
