Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further described, as shown in Figure 1, in the present embodiment, a kind of indoor optoelectrical cable, skin is provided with thickness 0.05mm aluminium-plastic tape lapped shielding layer 5 and thickness 1.2mm flame-proof polyvinyl chloride sheath 6, and four two core pair twist grid lines 4, three cross-sectional area of conductor 1.5mm are set in aluminium-plastic tape lapped shielding layer 5
2Insulated wire 1, the tightly packaged fiber unit 2 of two external diameter 0.9mm and the radio frequency cable unit 3 of external diameter 6.5mm form cable cores, the polyvinyl chloride insulation layer thickness of wherein said insulated wire 1 is 0.7mm, radio frequency cable unit 3 is made up of copper conductor 7, physically foamed pe insulation layer 8, copper wire woven shield 9, polyvinyl chloride sheath 10 from the inside to the outside successively, tightly packaged fiber 2 adopts G.657 colored optical fiber 11, outer covered with nylon layer 12.Described comprehensive cable external diameter overall diameter is 15.5mm, and cable can also adopt colouring discrimination so that arrange in concrete the enforcement.
Described optical fiber G.657 colored optical fiber coats nylon outward, makes optical fiber have good anti-microbend performance, and four two core pair twist grid lines carry out the twisting pitch combination, can effectively reduce decay, prevent to crosstalk.
The radio frequency cable unit adopts the physically foamed pe insulation layer, and its conductor decay is little, and the loss of signal is little, and the transmission rate height has excellent shielding properties, not disturbed by external electromagnetic field.
Cable core is provided with aluminium-plastic tape lapped shielding layer 5 and flame-proof polyvinyl chloride sheath 6 outward successively, makes it have excellent shielding properties and fire resistance.
Aforesaid indoor optoelectrical cable, polyvinyl chloride wire 1 cross-sectional area of conductor also can need be adjusted according to using, and is satisfied with the instructions for use of different ampacitys.
The foregoing description limits the utility model never in any form, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection range of the present utility model.
