Embodiment 1

[0031] A high-performance heat-resistant mineral fire-resistant cable, such as Figure 1-3 As shown, it includes a cable body 1, the cable body 1 includes an outer insulating layer 11, an inner insulating layer 12 and several cable cores 13, and a heat-resistant layer 111 and a steel wire mesh are tightly bonded between the outer insulating layer 11 and the inner insulating layer 12 layer 112 , the cable core 13 is located within the inner insulating layer 12 .

[0032] In this embodiment, the outer insulating layer 11 and the inner insulating layer 12 are all made of PVC (polyvinyl chloride) material, which has good wear resistance and corrosion resistance, and has better insulation and toughness, and lower cost. Advantages, prolong its service life.

[0033] Furthermore, the heat-resistant layer 111 is made of mineral fiber material, which has good heat insulation and fire prevention effects, and has the advantages of a stable structure and is not easy to crack, so as to im...

Embodiment 2

[0038] As a second preferred embodiment of the present invention, a filling rubber 131 is provided between the cable core 13 and the inner insulating layer 12 , so that the filling rubber 131 can play a role of shock absorption and compression resistance on the cable core 13 .

Embodiment 3

[0040] As the third preferred embodiment of the present invention, such as Figure 4-6 As shown, the cable body 1 is provided with a base 2, the upper surface of the base 2 is provided with a groove 21, and both ends of one side of the base 2 are tightly welded with fixing blocks 22, and the two fixing blocks 22 are tightly welded There is a rotating shaft 221, the other side of the base 2 is tightly welded with a baffle 23, the two ends of the upper surface of the baffle 23 are tightly welded with a screw 231, the screw 231 is provided with a nut 24, and the base 2 is provided with an arched cover Plate 3, one side of the arched cover plate 3 is tightly welded with a connector 31, the connector 31 is provided with a through hole 311, the other side of the arched cover plate 3 is tightly welded with a limiting plate 32, and the two sides of the limiting plate 32 Each end is provided with a round hole 321.

[0041]In this embodiment, the base 2 and the arched cover 3 are all m...

Abstract

The invention relates to the technical field of cables, in particular to a high-performance heat-resistant mineral fireproof cable. The cable comprises a cable body, and the cable body comprises an outer insulating layer, an inner insulating layer and a plurality of cable cores; a base is arranged on the cable body, and a groove is formed in the upper surface of the base; a rotating shaft is arranged between fixed blocks at the two ends of one side of the base, and a baffle is arranged at the other side of the base; an arched cover plate is arranged on the base, a connector is arranged at one side of the arched cover plate, and a limiting plate is arranged at the other side. According to the high-performance heat-resistant mineral fireproof cable provided by the invention, the cable body is placed in the groove in the base, the arched cover plate is rotated to a position buckled above the groove, and a nut is screwed into the bottom end of the screw rod, so that the nut is attached to the limiting plate, the limiting plate is fixed on the upper surface of the baffle, and the outer surface of the cable body can be wrapped by the base and the arched cover plate, thereby improving the compression resistance of the cable body, and solving the problem of poor compression resistance of the heat-resistant mineral fireproof cable.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-performance heat-resistant mineral fireproof cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulated covering, the cable has the characteristics of energization inside and insulation outside, and is a wire that transmits power or information from one place to another. At present, a heat-resistant mineral fireproof cable has appeared on the market, which can effectively improve the fireproof effect of the cable. Pressure loss, poor compressive performance, and inconvenient maintenance when circuit problems occur. In view of this, we propose a high-performance heat-resistant mineral fire-resistant cable. Contents of the invention [0003] The purpose of the present invention is to ...
