Product Introduction
Heat-resistant aluminum alloy stranded wire and high-strength steel core heat-resistant aluminum alloy stranded wire are wires made of heat-resistant aluminum alloy round wire and high-strength galvanized steel strand. With the rapid development of the national economy and the continuous improvement of the people's level, the demand for electricity has increased sharply, and the transmission line is increasingly developing to large capacity, which requires increasing the transmission capacity of the conductor. As a special wire with good performance, heat-resistant aluminum alloy has good advantages in China's urban network transformation, substation construction and general lines.
Features:
1. The long-term working temperature is 150 °C, and the short-term temperature can reach 180 °C, so that the continuous allowable current carrying capacity is 1.5-1.6 times that of ordinary wire of the same specification
2. It has the same strength as ordinary stranded wire at room temperature, and the strength is kept above 90% when running at high temperature.
3. No matter at room temperature or high temperature, it maintains the same degree of creep resistance compared with ordinary aluminum wire.
4. There is no big difference between the laboratory smoke test and the outdoor atmosphere exposure test.
Occasions of use:
1. It is especially suitable for high-current transmission bus in substations and power plants. It can save engineering investment.
2. In the urban network line expansion and reconstruction project, especially in the narrow area of the line corridor, only need to replace the conductor with similar cross-sectional specifications, and basically do not need to replace the tower, which can meet the strength and the relaxation requirements of the conductor to the ground.
3. In the double-circuit circuit, it can also carry the current carrying capacity of the other circuit for a short time, which is convenient for emergency repair and maintenance in the event of an accident in the circuit.
4. On the new line, the use of heat-resistant aluminum alloy wire simplifies the line structure, which has great benefits for the safe operation of the line.
Executive standards:
1. Heat-resistant aluminum alloy stranded wire and heat-resistant aluminum alloy round wire with high-strength heat-resistant aluminum alloy stranded wire shall implement the Q/ZJ3-2008 standard
2. High-strength galvanized steel wire with heat-resistant aluminum alloy stranded wire shall be implemented according to the standard GB/T3428-2012 standard (equivalent to the IEC60888: 1987
Heat-resistant aluminum alloy wire products implement Q/ZJ4-2008 |
