A mineral insulated fireproof cable

Abstract

The invention discloses a mineral insulated fireproof cable, which comprises a cable body, an installation ferrule is arranged inside the cable body, an electromagnetic shielding film is arranged on the outside of the installation ferrule, and a first mine is arranged on the outside of the electromagnetic shielding film. The material layer, the outer side of the first mineral layer is provided with an isolation liner. The invention fixes the conductive copper core by installing ferrules and installs the second mineral strip, which prevents the wires from being entangled and deformed, effectively supports the strength of the ferrule, facilitates installation and connection, and enhances the cable insulation effect. The electromagnetic shielding film effectively isolates electromagnetic radiation. , the first mineral layer can effectively insulate heat and fire, and cooperate with steel wire and polyimide fiber to make the cable have rigidity that is not easily deformed and good toughness for recovery. The isolation lining and armor can effectively protect the outer layer of the cable and reduce cable wear , The cable is not easy to twist and deform, has good fire and heat insulation effect, greatly reduces the probability of damage and short circuit, and can effectively dissipate heat through the heat dissipation holes and 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...

AI Technical Summary

Problems solved by technology

Generally, the cable sheath adopts copper sheath, the process is more complicated, the production efficiency is low, and the cost is high, and the cable is easy to break and deform, so that the insulation and fire prevention effect is poor, resulting in cable short circuit and other phenomena.
