Problems solved by technology
In the process of power transmission, if there is a short circuit or leakage, the heat accumulation on the conductor will eventually ignite the coating outside the conductor, thereby igniting other combustibles and making the fire out of control. Another situation is that other combustibles catch fire Ignite the cladding layer on the outside of the cable conductor, resulting in short circuit leakage of the circuit, etc., so that the cable becomes an accomplice to the further spread of the fire. Therefore, the safety performance of the existing cables is extremely difficult to be guaranteed during use, and needs to be improved urgently

Embodiment 1
[0017] A flexible mineral insulated fireproof cable is proposed, which includes multiple sets of wire cores. The wire core includes a conductor 1 and an insulating layer 2 covering the conductor 1. The conductor 1 is twisted with multiple metal wires, which can improve the overall tensile performance of the cable. , the metal wire is copper wire, which makes the cable have good electrical conductivity. The insulating layer 2 is made of mica material. Even when the temperature of the conductor 1 part is too high, the insulating layer 2 will not burn. When a fire occurs outside , due to the barrier of the insulating layer 2, it will not affect the power transmission of the conductor 1. Different insulating layers 2 have different colors, which can facilitate wiring operations. Multiple sets of wire cores are wrapped tightly with the wrapping layer 4, and the wrapping layer 4 is made of inorganic mineral materials. In the wrapping layer 4, there is a filling layer 3 between the wi...

The invention discloses a flexible mineral insulation fireproof cable which comprises multiple groups of cable cores, wherein multiple groups of cable cores are covered by adopting a lapped covering, a metal sleeve is wrapped outside the lapped covering, and the lapped covering is made of an inorganic mineral material. The flexible mineral insulation fireproof cable has the advantages of good electric conduction performance, better fireproof performance, higher toughness, good shielding performance, and no large damage to a human body when fire happens.
Description
technical field [0001] The invention relates to a flexible mineral insulated fireproof cable. Background technique [0002] Cables are the most widely used equipment for power transmission, however, in daily life, the safety of power usage is a matter of great concern. In the process of power transmission, if there is a short circuit or leakage, the heat accumulation on the conductor will eventually ignite the coating layer outside the conductor, thereby igniting other combustibles and making the fire out of control. Another situation is that other combustibles catch fire Ignite the cladding layer coated on the cable conductor, resulting in short circuit leakage of the circuit, etc., so that the cable becomes an accomplice to the further spread of the fire. Therefore, the safety performance of the existing cable is extremely difficult to be guaranteed during use and needs to be improved urgently. Contents of the invention [0003] In view of the problems existing in the p...
