Embodiment
[0014] Embodiment: As shown in Figure 1, a multi-core sub-shielded broadband cable includes an outer sheath 1, a wrap 2 in the outer sheath 1, and four subunits 3 in the wrap 2, each subunit The unit 3 includes 24 pairs of cables 4 , each subunit 3 is provided with a cable tie 5 , the cable tie 5 is covered with a wrapping tape 6 , and an aluminum-plastic-aluminum tape shielding layer 7 is provided outside the wrapping tape 6 .
[0015] The inner side of the outer sheath 1 can also be provided with a tearing rope 8, which can help to open the outer sheath and make the construction process more convenient.
[0016] The invention adopts the aluminum-plastic-aluminum tape shielding layer. When the frequency of the interference electromagnetic field is high, the eddy current generated in the metal material with low resistivity is used to form a counteracting effect on the external electromagnetic wave, thereby achieving the effect of shielding; it can effectively reduce Electromag...
