Embodiment 1

[0016] Embodiment 1: The mass percentage (weight percentage) of each component in the aluminum alloy conductor material of the rubber-sheathed flexible cable is as follows (taking the production of about 10,000 kg of aluminum alloy electrical poles as an example):

[0017] Pure iron powder: 3% (choose 300kg, purity 99.90%), niobium-tin intermediate ingot: 0.5% (choose 50kg), aluminum-boron alloy: 0.25% (choose 25kg), the balance is aluminum and ≤0.5% total amount of impurities. The above-mentioned aluminum is electrolytic aluminum liquid (approximately 9625 kg). The particle size of the above-mentioned pure iron powder is 80 mesh, and its carbon content is ≤0.03% (the carbon content is 0.02%).

[0018] The mass percentage of niobium in the niobium-tin intermediate ingot is 30%, and the mass percentage of tin is 70%. The manufacturing method of the niobium-tin intermediate ingot is to use a lathe to process the niobium metal block into niobium shavings (crumbs), put it into a...

Embodiment 2

[0023] Example 2: The mass percentage (weight percentage) of each component in the aluminum alloy conductor material of the rubber-sheathed flexible cable is as follows: pure iron powder: 3.5% (or 3.3%), niobium-tin intermediate ingot: 0.7% (or 0.6%), Aluminum-boron alloy: 0.26% (or 0.28%), the balance is aluminum and ≤0.5% of the total amount of impurities. The particle size of the above-mentioned pure iron powder is 100 mesh (or 90 mesh), and its carbon content is ≤0.03% (the carbon content is 0.025% or 0.03%);

[0024] The mass percentage of niobium in the above-mentioned niobium-tin intermediate ingot is 30%, the balance is tin, and the sum of the mass percentages of niobium and tin is 100%. The manufacturing method of the described niobium-tin intermediate ingot is to use a lathe Process it into niobium chips, put it into a Gan boiler and heat it to 1800~2200°C (choose 1800°C or 2000°C or 2200°C) to melt it, then put tin metal block at this temperature to melt it, and sti...

Abstract

The invention discloses a rubber jacketed flexible cable aluminum alloy conductor material and a manufacturing method thereof. The rubber jacketed flexible cable aluminum alloy conductor material comprises the following components in percentage by mass: 3%-3.5% of pure iron powder, 0.5%-0.7% of niobium-tin intermediate ingot, 0.25%-0.28% of aluminum-boron alloy, and the balance of aluminum and less than or equal to 0.5% of sum impurities. The manufacturing method comprises the following technological steps: adding an electrolytic aluminum liquid into a holding furnace, adding the pure iron powder, heating, and insulating and stirring; then adding the niobium-tin intermediate ingot into a melting liquid so as to be molten, insulating and stirring, then adding the aluminum-boron alloy so as to be molten, and insulating and stirring; removing impurities, to obtain a melting liquid, namely an aluminum alloy liquid; putting the aluminum alloy liquid into a rolling casting machine, and rolling to obtain an aluminum alloy rod; drawing out an aluminum alloy wire, and performing primary cooling and secondary cooling to the aluminum alloy wire during the motion process, to obtain an aluminum alloy wire, namely a conductor wire which is the rubber jacketed flexible cable aluminum alloy conductor material. The rubber jacketed flexible cable aluminum alloy conductor material is high in conductivity, light in weight, good in flexibility, high in tensile strength, large in current carrying capacity, and low in manufacturing cost.
