　　Dazheng Steel Core Heat Resistant Aluminum Alloy Stranded Wire, National Standard Overhead NRLH60GJ-240/30 Conductor

　　Characteristics of steel core heat-resistant aluminum alloy stranded wire:

　　 Aluminum alloy made by adding a small amount of zirconium to aluminum can improve its heat resistance, but has little effect on conductivity This research achievement was first proposed by the United States in 1950 In Japan, this heat-resistant aluminum alloy has received widespread attention from wire designers, and systematic research and testing have been conducted since 1960 At present, Dazheng Electric Wire Co., Ltd. has formulated specifications and standards for the production and use of this type of wire The allowable continuous working temperature of this new heat-resistant aluminum alloy wire is 150 ℃, and the conductivity is 60% of the international standard tough copper In a dual circuit power supply, when one circuit experiences an accident, the other circuit can operate at high temperatures and overload without damaging the wires, which is beneficial for safe power transmission In addition, due to its lighter weight compared to ordinary steel cored aluminum wire, although the price is slightly higher, the construction cost is lower

　　This utility model relates to a special aluminum alloy wire Mainly solves the problem of poor temperature resistance of existing wires, which limits the transmission capacity of wires and reduces transmission efficiency The aluminum alloy wire comprises a body, characterized in that the body is composed of a core located at the center and aluminum alloy wires located at the periphery of the core twisted together The core of the wire is twisted with ultra heat-resistant aluminum alloy single wire, which can effectively increase the current carrying capacity of the wire, increase the transmission capacity of the wire, and improve the utilization rate of aluminum. It also has the advantages of high strength and cost saving

　　1. A special aluminum alloy wire based on a body, characterized in that the body is composed of a wire core (1) located at the center and an aluminum alloy wire (2) located at the periphery of the wire core (1) twisted together.
