Problems solved by technology

[0003] Most cables today don't work properly in the event of problems with the grid lines or in the event of a fire or other disaster
Magnesia mineral fire-resistant insulated cables and mica tape-wound fire-resistant cables on the market have disadvantages in actual use. Magnesia mineral fire-resistant insulated cables require special production and processing equipment for cables of this structure, and the production of magnesium oxide mineral fire-resistant Insulated cable equipment not only needs to be imported, but also very expensive, and the capital investment is too large; in addition, copper sheathed magnesia mineral fireproof insulated cables have special requirements in the process of production, processing, transportation, line laying, installation and use, such as magnesia The production and processing of mineral fire-resistant insulated cables cannot be as convenient as polymer materials. It is difficult to lay and install, and the cost of raw materials is high. It is difficult to popularize and use them on a large scale, especially difficult to promote them in civil buildings, etc.
The fire-resistant cable wrapped with mica tape needs to be wound in multiple layers in the production process. Due to the limitation of process conditions, it is easy to cause defects at the lap joints. It is difficult to ensure the safety and smoothness of communication and power cables in case of fire

Abstract

The invention relates to a ceramic fireproof optical fiber composite power cable. The ceramic fireproof optical fiber composite power cable comprises conductors, wherein the number of the conductors is three, an inner ceramic fireproof composite belt is arranged outside the conductors, a filling layer is arranged outside the inner ceramic fireproof composite belt, an optical fiber is arranged in the filling layer, an outer ceramic fireproof composite belt is arranged outside the filling layer, and a low-smoke zero-halogen jacket layer is arranged outside the outer ceramic fireproof composite belt. The ceramic fireproof optical fiber composite power cable is good in fireproof effect, high in allowable working temperature, high in transmission capacity, high in reliability, low in failure rate, easy to install and wide in application range.

Description

technical field [0001] The invention relates to a cable, in particular to a ceramic composite cable. Background technique [0002] With the rapid development of the national economy, as the main artery of the national economy, the amount and scope of wire and cable are increasing. In recent years, power plants, substations, smelting and petrochemical industries have a great demand for cables. [0003] Most cables today don't work properly when there is a problem with the grid line or if there is a fire or other disaster. Magnesia mineral fire-resistant insulated cables and mica tape-wound fire-resistant cables on the market have disadvantages in actual use. Magnesia mineral fire-resistant insulated cables require special production and processing equipment for cables of this structure, and the production of magnesium oxide mineral fire-resistant Insulated cable equipment not only needs to be imported, but also very expensive, and the capital investment is too large; in add...
