Problems solved by technology
Based on this, fire-resistant wires have high requirements on materials. In addition to the conventional protective layer of fire-resistant materials, the current fire-resistant wires will add inorganic mineral layers to the fire-resistant materials. For the convenience of adding, the inorganic mineral layer is usually made into powder first. , and then fill it in, or place the powder in a fixed bag, and then sandwich it in the protective layer, but the disadvantages of this are: it is time-consuming and laborious to fill in, and the uneven distribution of the filler will affect the fire-resistant effect

Abstract
The invention discloses an isolated inorganic mineral insulated fire-resistant wire. The wire comprises at least three conductors, the conductors are wrapped by jelly and then is sealed in an insulating sealing sleeve; a first fireproof insulating layer, a metal shielding layer, a second fireproof insulating layer and an outer sheath are sequentially arranged outside the insulating sealing sleeve; a first annular channel is arranged in the first fireproof insulating layer; a second annular channel is formed in the second fireproof insulating layer, a first longitudinal groove is formed in thefirst fireproof insulating layer, a second longitudinal groove is formed in the metal shielding layer, a third longitudinal groove is formed in the second fireproof insulating layer, and a first cementing inorganic mineral layer and a second cementing inorganic mineral layer which are poured through the three longitudinal grooves are arranged in the first annular channel and the second annular channel respectively; the isolated inorganic mineral insulated fire-resistant wire is better in fireproof performance, the inorganic mineral layer is more convenient and uniform to fill, and time and labor are saved.
Description
technical field [0001] The invention relates to a fire-resistant wire, in particular to an isolated inorganic mineral insulated fire-resistant wire, which belongs to the technical field of electric wires and cables. Background technique [0002] Fire-resistant wire refers to the wire that can keep running safely for a certain period of time under the condition of flame burning. The fire-resistant wire requires that the line can still be energized normally for a certain period of time when a fire occurs, that is, under the condition of burning at a certain flame temperature; Normal transmission of electric energy, transmission of various control signals, and alarm signals within a certain period of time, so that lighting, fire alarm devices and other emergency equipment can continue to be powered on within a certain period of time, so that rescue work can be carried out normally. Based on this, fire-resistant wires have high requirements on materials. In addition to the conve...
