Antiflaming fireproof aluminum alloy power cable

Abstract

The invention discloses an antiflaming fireproof aluminum alloy power cable, comprising an insulation layer, wherein a plurality of cable cores are arranged in the insulation layer; a first mounting slot and a second mounting slot are arranged on the outer side wall of the insulation layer; a first groove is arranged on the inner wall at one side of the first mounting slot; a first placing slot is arranged on the inner wall at the side of the first groove away from the opening of the first groove; a first moving post is mounted in the first placing slot in a sliding mode; and one end of the first moving slot stretches into the first groove and is welded with a first clamp block. According to the cable, the structure is simple; through rotation of a rotation wheel, the first clamp block and a second clamp block are respectively clamped into a first clamp slot and a second clamp slot, and a first fire retardant placing box and a second fire retardant placing box are fixedly mounted in the first mounting slot and the second mounting slot, thereby finishing mounting the cable; the operation is simple; a fireproof antiflaming function is achieved; and the cable is convenient for installation or replacement and is convenient for use.

Description

Technical field [0001] The invention relates to the technical field of cables, in particular to a flame-retardant and fire-proof aluminum alloy power cable. Background technique [0002] With the development of economic science and the promotion of industry, most cables currently use copper core conductors. Due to the high cost of copper conductors, aluminum alloy cables are recognized by the State Grid in developed countries. Compared with aluminum alloy cables and copper core cables, The advantages are: under the same cross-section, the current carrying capacity of the aluminum composite cable conductor is twice that of the copper conductor; the creep resistance of the cable ensures the continuous and stability of the cable during overload and overheating; the aluminum alloy cable is lighter in construction Convenient; the practical life of the cable is longer than that of the copper cable; the cost of the aluminum alloy cable is lower, so people began to use the aluminum alloy...

Problems solved by technology

[0002] With the development of economic science and the promotion of industry, most cables currently use copper core conductors. Due to the high cost of copper conductors, aluminum alloy cables have been recognized by the State Grid in developed countries. Compared with aluminum alloy cables and copper core cables, their The advantages are: under the same section, the current carrying capacity of the aluminum alloy cable conductor is twice that of the copper conductor; the creep resistance of the cable ensures the continuity and stability of the cable when it is overloaded and overheated within a certain period of time; the aluminum alloy cable is light in construction Convenient; the practical life of the cable is longer than that of the copper cable; the cost of the cable is lower than that of the aluminum alloy cable, so people began to use the aluminum alloy cable instead of the copper core cable, but when the cable breaks and causes a fire, the safety cannot be guaranteed. The flame retardant is installed in the cable to prevent the occurrence or spread of fire, but the flame retardant is not easy to install in the cable, and it is not convenient to replace the flame retardant in the cable, so we propose a flame-retardant and fire-resistant aluminum alloy power cable to solve the above-mentioned problems
