Embodiment approach

[0046] The implementation method is specifically as follows: the conductive copper core 7 is clamped in the first clamping groove 26, and the clamping elastic force and friction force of the clamping arm 24 and the occlusal teeth 25 are used to effectively fix the conductive copper core 7 to prevent the gap between the wires. Intertwined and deformed, the second mineral strip 8 slides into the second clamping groove 27 to effectively support the strength of the installation ferrule 2, which is convenient for installation and connection and enhances the insulation effect of the cable. The electromagnetic shielding film 3 effectively isolates electromagnetic radiation. The first mineral layer 4. It can effectively insulate heat and prevent fire. With the combination of steel wire and polyimide fiber, the cable has rigidity that is not easily deformed and good resilience. The isolation lining 5 and armor 6 can effectively protect the outer layer of the cable and reduce cable wear. ...

Abstract

The invention discloses a mineral insulated fireproof cable, which comprises a cable body, wherein an installation clamping sleeve is arranged in the cable body, an electromagnetic shielding film is arranged on the outer side of the installation clamping sleeve, a first mineral layer is arranged on the outer side of the electromagnetic shielding film, and an isolation lining is arranged on the outer side of the first mineral layer. According to the invention, a conductive copper core is fixed through an installation clamping sleeve, and a second mineral substance strip is installed, so that mutual winding deformation among conducting wires is prevented, the strength of the installation clamping sleeve is effectively supported, installation and connection are facilitated, and the insulation effect of the cable is enhanced; and an electromagnetic shielding film effectively isolates electromagnetic radiation, a first mineral substance layer can effectively insulate heat and prevent fire, matching of steel wires and polyimide fibers makes a cable have rigidity which is not easy to deform and toughness which is good in recovery performance, and an isolation lining and an armor effectively protect the outer layer of the cable to reduce cable abrasion, so that the cable is not easy to twist and deform, the fireproof and heat insulation effects are good, the probability of breakage and short circuit is greatly reduced, and effective heat dissipation can be achieved through the heat dissipation holes and the ventilation holes.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to a mineral insulated fireproof cable. Background technique [0002] Cables are widely used in control installation, equipment connection, and power transmission, and are an indispensable and important transmission medium in industry and civil use. Cables have various specifications and models to meet the needs of different equipment and transmission purposes. Cables can short or open during use, causing power and information transmission to fail. In the event of a fire, the cable needs to have a certain fire protection function, so as to ensure that the data can be effectively saved before the line is paralyzed, reduce the risk of data loss, and ensure that the cable can ensure the safety of electrical equipment and lines during the power transmission process. run. [0003] In order to save more lives, property and information from the ruthless fire scene, the applicati...
