Abstract

The invention belongs to the technical field of machinery, relates to a cable and particularly discloses a shielding type category-6 type cable with water blocking and tensile functions. The cable comprises a cable core, an inner sheath and an outer sheath from inside to outside in sequence, wherein the cable core is filled with water-blocking ointment to form a diaphragm with moisture in a cable embedded ground; and the water-blocking ointment comprises the following components in parts by weight: 20-30 parts of paraffin-base oil, 50-60 parts of naphthenic oil, 5-10 parts of organic thickening agent, 3-6 parts of fumed silica, 3-5 parts of oil separation inhibitor, 3-8 parts of expanded microsphere particles, 1-3 parts of aluminum silicate salt mineral particles, and 0.05-1 parts of antioxidant. By filling the cable core with the water-blocking ointment, the waterproof performance of the cable is greatly improved, the cable density is lowered, and meanwhile, the impedance performance of the cable is effectively improved, so that the service life of the cable is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a cable, in particular to a shielded Cat6e cable with functions of water resistance and tension resistance. Background technique [0002] With the rapid development of optical communication technology, optical cables have been widely used in the backbone network and inter-office trunk lines of wired communication networks, and it has become an inevitable trend for optical fibers to enter the access network. [0003] Existing data cables include a cross-shaped skeleton and a sheath arranged outside the cross-shaped skeleton, and multiple sets of twisted wire pairs are respectively arranged in the installation grooves corresponding to the skeleton. When a data cable with such a structure is used, each set of wire pairs The relative position of the cable is easy to shift, and the anti-crosstalk performance is weak, which affects the service life of the cable. And the waterproof per...
