针对实际输电线路的工程应用要求，开展了新型铝包镍钼合金钢芯耐热铝合金导

Aiming at the engineering application requirements of actual transmission lines, the structural design and preparation technology of new aluminum-clad nickel-molybdenum alloy steel core heat-resistant aluminum alloy conductors were developed, and samples of new aluminum-clad nickel-molybdenum alloy steel core heat-resistant aluminum alloy conductors were developed, and Through third-party type test verification, the cost is more than 25% lower than that of the same type of conductors in active service. It has realized the engineering application of 66kV and above voltage transmission lines belonging to the State Grid Liaoning, Jiangsu, and Jilin companies, and formed the "Al-clad nickel-molybdenum alloy. "Technical conditions of steel core heat-resistant aluminum alloy wire" laid a good foundation for the low-cost preparation and popularization of this type of wire.

In view of the engineering application requirements of the actual transmission line, the structural design and preparation technology of the new aluminum-encased nickel alloy steel core heat-resistant aluminum alloy conductors were carried out, a new type of aluminum-packed nickel alloy core was developed and a sample of heat-resistant aluminum alloy conductors was developed, and the cost was verified by a third-party type, the cost was reduced by more than 25% compared with the same type of conductors in active operation, and the engineering application of the 66kV and above voltage-grade transmission lines belonging to the national network was realized. , laid a good foundation for the low-cost preparation and promotion of this type of wire.

According to the engineering application requirements of the actual transmission line, the structural design and preparation technology of the new aluminum clad nickel molybdenum alloy steel core heat-resistant aluminum alloy conductor are studied, and the new aluminum clad nickel molybdenum alloy steel core heat-resistant aluminum alloy conductor sample is developed, and the cost is reduced by more than 25% compared with the same type conductor in current service through the third-party type test, which realizes the application in Liaoning, Jiangsu and Jilin Power Grid The engineering application of 66kV and above voltage grade transmission lines affiliated to the company has formed the technical conditions of aluminum clad nickel molybdenum alloy steel core heat resistant aluminum alloy conductor, which has laid a good foundation for the low-cost preparation and popularization and application of this type of conductor.
