enameled aluminum wire is the main type of winding wire. It consists of two parts: conductor and insulating layer. After the bare wires are softened by annealing, they are baked.
Enameled aluminum wire has excellent high temperature resistance, mechanical properties, electrical and chemical properties and excellent frost resistance. Suitable for medium and long-term operation of 200℃ refrigeration equipment and chemical corrosion electrical equipment, dry-type transformers, oil-immersed transformers, epoxy cast transformers, iron removers, electromagnets and other electromechanical equipment.
Advantages of enameled aluminum wire
1. Compared with copper enameled wire, enameled aluminum wire is easier to wind, and there is a solid oxide film on the surface of enameled aluminum wire, which has good insulation effect and long life.
2. Due to the good insulation effect of the aluminum film layer, the heat-resistant temperature can be 20 degrees higher than that of the copper wire.
3. The biggest advantage of using aluminum is that it is 1/3 lighter than copper, which greatly reduces production costs. Secondly, it can be easily attached to solids. Thirdly, it can also reduce freight and transportation during operation.
The enameled copper wire is not insulated, and the enameled aluminum wire has an insulating paint film on the surface, which can be used directly.
Advantages of aluminum wire:
(1) Cheap price: Copper rods are 3.5 times the price of aluminum rods, and the specific gravity of copper is 3.3 times that of aluminum. Therefore, aluminum wire cables are much cheaper than copper wire cables and are suitable for low-cost projects or temporary electricity use.
(2) The cable is very light: the weight of the aluminum wire cable is 40% of the copper wire cable, and the construction and transportation costs are low.
(3) Anti-oxidation and corrosion resistance: Aluminum reacts with oxygen in the air to form an oxide film, which can prevent further oxidation. Therefore, aluminum wire is an indispensable material for high-voltage, large-section, and large-span overhead power transmission, but its advantages as a low-voltage line no longer exist.
But in fact, the existence of Round Enameled Aluminum Wire and the role of enameled aluminum wire are the same, and may be regarded as different in terms of use or direction.
