Description
Technical field:
The utility model relates to a kind of cable, is specifically related to a kind of photoelectric combination control cables.
Background technology:
Nuclear energy industry is the new industry in national economic development, as the electric wire of nuclear energy nerve, blood vessel, is directly connected to the fail safe of nuclear energy, reliability, advance; Along with the deep development of Chinese national economy, increasing to the demand of the energy, improve that nuclear energy is powered, the measure of the control system aspect such as safely will be directly connected to the development of nuclear energy, how research improves nuclear energy control cables performance, to reduce the manufacturing cost of control cables, to expand the applicable scope of control cables.
Current domestic nuclear power uses control cables mainly to cash at cable feature single, finished cable external diameter is large, can not fit the demand of modern nuclear power development, along with the development of modern science and technology informationization, high speed, integrated and safe, propose more strict requirement to nuclear power station, require that the construction of cable is simple, product external diameter is little, good weatherability, electromagnetism interference excellent performance.
Utility model content:
The purpose of this utility model is to provide a kind of photoelectric combination control cables, and to meet the requirement of nuclear power station to cable feature and structure, applicability is wide, adaptable.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions:
A kind of photoelectric combination control cables, include oversheath, described oversheath is wrapped in total screen successively, lapping layer, insulated wire cores A is enclosed with in described lapping layer, insulated wire cores B, insulated wire cores C, insulated wire cores D, optical fiber, shielding core A, shielding core B, shielding core C, described insulated wire cores A, insulated wire cores B, insulated wire cores C, insulated wire cores D is made up of the outer extruded insulation layer of conductor, described shielding core A is made up of three outer stranded two insulated wire cores of core in screen, described shielding core B is made up of two outer stranded insulated wire cores of core in screen, described shielding core C is made up of core strand insulation high core in screen, insulated wire cores A is provided with between described shielding core A and shielding core B, described insulated wire cores B, insulated wire cores C, insulated wire cores D and insulated wire cores A is stranded.
Described core is made up of two mutual stranded outer extruded insulation layers of conductor, and described insulated wire cores is made up of the outer extruded insulation layer of conductor.
Described conductor is made up of tin-coated copper twisted wire material.
Described insulating barrier is made up of extraordinary fluoroplastics and special elastomer.
Described screen and total screen shield heat-resistant fireproof band by novel height and form.
Described oversheath is made up of wear-resisting special high-strength elastomer.
In the utility model, conductor adopts tinned wird stranded conductor, and conductor has the characteristic of structurally flexible, and stranded conductor can improve the pliability of conductor simultaneously, compared with single conductor, and not easy fracture, coefficient of safety is high; Insulating material adopts extraordinary fluoroplastics and special elastomer to form, and fluoroplastic insulation is coated through high temperature extrusion, and insulation thickness is ultra-thin, is only 0.1 ~ 0.15mm; Outer coated through high-speed extrusion special elastomer at fluoroplastic insulation layer, this material softness, proportion is little; Screen and total screen adopt novel height to shield heat-resistant fireproof band and are entwined, band internal layer has three layers of tin-coated copper particle, adds shielding reflector, compared with shielding with the equal tinned wird of tradition, adopt band shielded type cable more soft, shield effectiveness is better; Jacket material adopts wear-resisting special high-strength elastomer to form, and this protective cover material is through extruder extrusion cladding, and sheath has the performance such as good softness, oil resistant, cold-resistant, crack resistence, UV resistant, is convenient to mounting and installation.
The beneficial effects of the utility model: the utility model structure is simple, nuclear power station can be met to control cables functional diversities, high speed, the requirement of the development of integrated and safe, finished cable is soft, installation radius is little, shield effectiveness is good: because cable adopts band shielding design, such structural design has more soft than traditional braiding structure cable, be more suitable for installing, in Cable Bending Radius, tradition braided shield cable minimum bending radius is 6 times of outside diameters of cable, and adopt the cable of wrapped shielding construction, minimum bending radius can reach 4.5 times of finished cable external diameter, traditional braiding structure cable, under the prerequisite of 85% braid shielded density, shield effectiveness is the shielding attenuation of 50-60dB, and adopts novel height shielding heat-resistant fireproof band, and shielding attenuation can reach 60-70dB, and shield effectiveness is benefited obviously.
Be described further below in conjunction with accompanying drawing.
