High-speed rail rare earth aluminum alloy fire alarm cable

Abstract

The invention relates to the technical field of cables, in particular to an aluminum-alloy cable and a high-iron rare-earth aluminum-alloy fireproof warning cable. The high-iron rare-earth aluminum-alloy fireproof warning cable comprises at least two high-iron rare-earth aluminum alloy conductors, insulation protection layers, an external protection layer, a water blocking layer, a fireproof layer, a filling layer, a warning layer and a temperature monitoring module, wherein the insulation protection layer is arranged on an outer surface of each high-iron rare-earth aluminum alloy conductor and comprises an epoxy resin layer and tungsten oxide nanoparticles, the tungsten oxide nanoparticles are dispersed in the epoxy resin layer, and the temperature monitoring module is used for monitoring a temperature of at least one high-iron rare-earth aluminum alloy conductor in real time. By the high-iron rare-earth aluminum-alloy fireproof warning cable, a better fireproof effect can be achieved, a core temperature of the cable is monitored in real time, a warning is timely given out, and the safe application of the cable is achieved; infrared radiation also can be absorbed very well to achieve a better heat absorption and heat insulation effect; and moreover, the requirement of an environmental-friendly cable is reached, the light demand is satisfied, and the cable manufacturing cost is greatly reduced.

Description

Technical field: [0001] The invention relates to the technical field of electric wires and cables, in particular to aluminum alloy cables, in particular to a high-iron rare earth aluminum alloy fireproof alarm cable. Background technique: [0002] In the field of power transmission and information transmission, cables are important transmission media, and copper cables, aluminum cables and aluminum alloy cables are more commonly used. As we all know, copper cables have many advantages in terms of electrical, mechanical, and durability, but the price of copper is much higher than that of aluminum. For a long time, the price of copper has been more than three times that of aluminum; The current situation and the development of electrification, informatization and networking have greatly increased the demand for cables, and aluminum cables and aluminum alloy cables have increasingly replaced copper cables. Due to the poor mechanical properties and corrosion resistance of ordin...
