Abstract
The invention discloses an indoor-outdoor data communication cable for a shielding enhanced room. The cable comprises a cable core, as well as an inner belting layer, an inner shielding layer, an inner sheath, an outer shielding layer and an outer sheath, which are sequentially wrapped outside the cable core from the inside out; and a grounded conductor is arranged between the inner sheath and the outer shielding layer. According to the invention, the cable adopts two shielding structures, namely, the inner shielding layer, which is made of Aluminum foil in a wrapped manner and improves the flexibility of the cable, and the outer shielding layer, which is a copper cladding aluminum strip and has the characteristics of electrical conductivity, high strength, and good shielding effect. And as the grounded conductor is arranged between the inner sheath and the outer shielding layer, the shielding performance of the cable in an electromagnetic dense environment is ensured.
