Embodiment Construction
[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.
[0017] Such as figure 1 As shown, a carbon fiber-reinforced fire-resistant power cable includes several conductors 1 that are enclosed and distributed along the circumferential direction. The center of the conductor 1 is provided with a load-bearing reinforcing core 4, and the exterior of several conductors 1 is covered with an isolation layer 5, and the exterior of the isolation layer 5 is coated with a sheath layer 6. Filler 7 is provided between.
[0018] Based on the above, it can be known that using the fire-resistant mica tape 2 as the fireproof layer of the cable can ensure that the cable can be powered normally within a certain period of time when the flame is burning. The cable adopts a reinforced core structure, which can protect the components and cable structure inside the ...

The invention relates to a carbon fiber reinforced fire-resisting power cable. The carbon fiber reinforced fire-resisting power cable comprises a plurality of conductors distributed in an encircling mode in a circumferential direction, the outside of the conductors are sequentially wrapped by a fire-resisting mica tape and a halogen-free low-smoke insulating layer, the center of the conductors distributed in the encircling mode is provided with a bearing reinforcing core, the outside of the plurality of conductors is covered with an isolating layer, the outside of the isolating layer is covered with a sheath layer, and filler is filled between the isolating layer and the conductors, the conductors are made of oxygen-free copper, the bearing reinforcing core is made of carbon fiber ropes, the isolating layer is made of ceramic silicon rubber fire-resisting materials, and the sheath layer is made of halogen-free low-smoke fire-retarding materials. The carbon fiber reinforced fire-resisting power cable has the advantages of being high in tensile strength and vibration resistance, fire-retarding, fire-resisting, environmental in applied materials, stable and durable in performance, good in airtightness and waterproofness, safe and reliable in power supply, convenient to mount and construct, low in environmental requirement, light in weight, small in space occupation, low in servicelife, free from maintenance and the like.
Description
technical field [0001] The invention relates to the technical field of power cables, in particular to a carbon fiber reinforced fire-resistant power cable. Background technique [0002] With the continuous deepening of the urbanization process, how to safely and effectively distribute electric energy to a large number of high-rise buildings with high drop at low cost has become a technical problem that Chinese wire and cable manufacturers urgently need to solve. Power cables laid in high-rise buildings with high drop, due to their body weight, run for a long time, due to tension, the cable conductor will inevitably become thinner, the conductor resistance will increase, the conductivity will deteriorate and may cause The insulation and sheath of the cable are damaged or even torn. [0003] Carbon fiber reinforced fire-resistant power cables can have better performance and longer service life by placing carbon fiber reinforced cores in the cables and selecting appropriate fi...
