Aluminum Tube Cable: Lightweight and High-Performance Power Transmission Solution

With the rapid development of modern industry and infrastructure construction, the efficiency, safety and durability of power transmission systems have become key considerations. In this context, aluminum tube cable, as an emerging power transmission material, has gradually attracted widespread attention due to its unique performance advantages. It not only solves the problem of high cost of traditional copper cables, but also improves the overall performance of cables through innovative design.
Lightweight design
The core advantage of aluminum tube cable is its light weight. Compared with traditional copper cables, the density of aluminum is only about one-third of that of copper, and the use of hollow tubular structure further reduces the overall weight. This makes aluminum tube cable have significant advantages in long-distance power transmission and high-altitude erection scenarios, which can reduce the load of supporting structures and reduce construction difficulty and cost.
High conductivity
Although the conductivity of aluminum is slightly lower than that of copper, by using high-purity aluminum alloy materials and optimizing the cross-sectional area of ​​the conductor, the conductivity of aluminum tube cable can reach or even approach the level of copper cable. In addition, the hollow structure reduces eddy current loss and improves the transmission efficiency of the cable.

Excellent mechanical properties
Aluminum tube cables are made of high-strength aluminum alloy materials with good tensile strength and corrosion resistance. They can maintain stable performance even in harsh environments such as moisture, salt spray or high temperature conditions.
Energy saving and environmental protection
Aluminum is a renewable resource, and its energy consumption in mining and processing is much lower than that of copper. In addition, the design of aluminum tube cables reduces the amount of materials used, conforms to the concept of sustainable development, and provides an ideal solution for green energy transmission.
Economical
The price of aluminum is much lower than that of copper, and its reserves are abundant, so aluminum tube cables have significant cost advantages. For large-scale power engineering projects, the use of aluminum tube cables can greatly reduce the initial investment.
Manufacturing process and technology
The production of aluminum tube cables involves multiple advanced technologies and process links. The following are the main steps:
Aluminum alloy smelting and extrusion
After smelting and casting, high-purity aluminum alloys are formed into a hollow aluminum tube structure through precision extrusion equipment. The temperature and pressure must be strictly controlled during the extrusion process to ensure the uniformity and surface finish of the tube.
Heat treatment and strengthening
The extruded aluminum tube undergoes a heat treatment process, such as annealing or aging hardening, to improve its mechanical strength and electrical conductivity. This step is critical to the overall performance of the cable.
Insulation layer and sheath processing
High-performance insulation materials (such as cross-linked polyethylene XLPE) are wrapped around the outer layer of the aluminum tube, and then an outer sheath is added to provide additional protection. These materials must have high temperature resistance, corrosion resistance and aging resistance to adapt to complex use environments.
Quality inspection
After production, aluminum tube cables must undergo rigorous electrical performance tests, mechanical performance tests and environmental adaptability tests to ensure that they meet international standards (such as IEC or GB).
Application areas of aluminum tube cables
