Good conductivity.

I. Common Features:

Low price and convenient installation and maintenance;
Suitable for various voltage levels, mainly used for high-voltage and ultra-high-voltage long-distance power transmission;
Especially applicable in situations where the path is limited or multiple lines need to be erected.

II. Anti-Corrosion Type:

In harsh climatic conditions with strong corrosivity such as heavy rain, humidity, and salt spray;
In industrial areas or high-pollution areas near chemical plants;
Coastal areas with salt spray corrosion;
High-altitude areas with changeable climate and large temperature differences;
Forests and swamps with high humidity where the air may contain microorganisms and organic substances, which easily cause wire corrosion;
Urban environments with air pollution and acid rain.

III. Aluminum Alloy Type:

Medium and heavy ice areas, and crossings over rivers and canyons;
Power transmission renovation projects with capacity increase needs, tight line corridors, economically developed cities, large gaps between peak and valley electricity consumption, and requirements for short construction periods;
Used for long spans or extremely harsh environments.



IV. Aluminum-Clad Steel Type:

High-voltage power transmission: Aluminum-clad steel-cored aluminum stranded wires are superior to steel-cored aluminum stranded wires in terms of conductivity, tensile strength, corrosion resistance, and service life. In developed countries abroad, they have been widely used to replace steel-cored aluminum stranded wires in high-voltage power transmission in addition to being used for manufacturing optical fiber composite overhead ground wires;
Substations: In substations, aluminum-clad steel-cored aluminum stranded wires are mainly used as conductors for main roads or branch roads. They can not only withstand large currents and pressures but also have a long service life and good anti-corrosion performance;
Special electrical equipment: Special electrical equipment often requires cables to have high strength and rigidity to withstand the operating load of the equipment and the impact of the external environment. Due to the addition of the steel core, aluminum-clad steel-cored aluminum stranded wires have high mechanical strength and stability, making them suitable for connecting some special electrical equipment with high requirements.
