Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more specifically to a corrugated copper sheathed flexible mineral insulated fireproof cable. Background Art

[0002] Cables are usually made of several or several groups of wires (at least two wires in each group) twisted together into a rope-like cable. Each group of wires is insulated from each other and often twisted around a center wire. The entire outside is covered with a highly insulating covering. The cable has the characteristics of being powered inside and insulated outside.

[0003] However, the existing cables still have many disadvantages in actual use. For example, the outermost protective sheath of the cable is easily subject to external wear, which may expose the internal copper wire, leading to leakage and short circuit, and the heat dissipation effect is poor, which may cause the cable to heat up. Utility Model Content

[0004] The utility model provides a corrugated copper sheathed flexible mineral insulated fireproof cable, which aims to solve the problem that the outermost protective sheath of the existing cable is easily subject to external wear, which will lead to the exposure of the internal copper wire, resulting in leakage and short circuit, and the heat dissipation effect is not good, which will cause the cable part to heat up.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a corrugated copper sheathed flexible mineral insulated fireproof cable.

[0006] In a preferred embodiment, the invention comprises four cable copper wires, wherein mineral insulating sleeves are fixedly connected between the outer sides of the four cable copper wires, a filling rope is wound around the outer side of the mineral insulating sleeve, a silicone layer is fixedly connected to the outer side of the filling rope, a protective sleeve is fixedly connected to the outer side of the silicone layer, corrugated rubber strips are fixedly connected to the outer side of the protective sleeve at equal intervals, an outer protective rubber sleeve is fixedly connected between the tops of a plurality of the corrugated rubber strips, and heat dissipation elastic rubber strips are fixedly connected to the outer side of the outer protective rubber sleeve at equal intervals.

[0007] In a preferred embodiment, talcum powder is applied between the filling rope and the mineral insulation sheath, and a ground wire is fixedly connected inside the mineral insulation sheath and between the copper wires of the cable.

[0008] In a preferred embodiment, a copper wire mesh is fixedly connected between the filling rope and the silica gel layer.

[0009] In a preferred embodiment, a plurality of the corrugated rubber strips are cross-connected.

[0010] In a preferred embodiment, the outer sides of the copper wires of the cable are all sheathed with an isolation layer.

[0011] In a preferred embodiment, the filling rope is made of polypropylene fiber.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model can avoid the wear of the outer protective rubber sleeve during the dragging of the cable through the heat dissipation elastic rubber strip, and can separate the outer protective rubber sleeve from the ground. At the same time, the outer protective rubber sleeve can also increase the area in contact with the air, making it easier to dissipate heat for the cable. At the same time, the pleated rubber strip can increase the elasticity of the cable, so that it can greatly buffer when it is subjected to external impact, and has a certain heat dissipation effect. The mineral insulation sleeve can protect and insulate the cable;

[0014] 2. The utility model uses talcum powder to avoid the adhesion of the filling rope and the mineral insulating sleeve. The ground wire can be connected to the neutral wire to ensure the safety of electricity use. The copper wire mesh mainly plays the role of strengthening the cable's tensile strength and preventing rat bites and corrosion. Since the pleated rubber strips are cross-connected, the resilience and cushioning of the pleated rubber strips are increased. The isolation layer prevents leakage and oxidation of the cable copper wire. Since the filling rope is made of polypropylene fiber, it can keep the cable round when it is cabled.
