Which Stabilizer is Best Copper or Aluminium?

Hey Pal,

Have you ever given the wiring and internal parts of the voltage stabiliser you intend to purchase to protect your home appliances any thought? Probably not. Most people ignore these crucial nuances. The most crucial element that significantly affects how a voltage stabiliser functions is the winding material. There are two options for the winding material: aluminium and copper. The million-dollar question is now: which stabilizer is best copper or aluminium?

As my father was a metallurgical engineer hence, I learned from him that whenever one is confused regarding stabilizer aluminium or copper, it is always better to choose copper over aluminium.

• Thermal Connectivity

When it comes to lowering the hot-spot temperature rise in transformer windings, copper has an advantage over other materials in terms of thermal conductivity. This advantage, however, is only possible provided the size, geometry, and design of the two windings are comparable.

The same thermal conductivity properties can also be obtained from aluminium by increasing the coil's cross-sectional area by 66%.

• Current Distribution

When compared to aluminium, copper has better metallurgical qualities that make it a better electrical conductor. A more equal, dependable, and steady distribution of current is possible with copper winding than with aluminium winding.

• Terminations

One issue with aluminium stabilisers is the oxidation that results, which makes it difficult to easily separate from terminations. Again, copper is the material of choice since it is delicate and simple to separate. Because of this, copper stabilisers outlast their aluminium equivalents.

• Connections and performance

Copper stabilisers operate better and are more efficient than aluminium stabilisers due to decreased energy losses. The oxides, chlorides, and sulphides in copper make it more conductive than aluminium. Because aluminium connections are prone to corrosion, it is particularly crucial to keep their joints clean and secure. Additionally, the connections between copper construction wire and aluminium transformers are not very reliable.

• Strength and flexibility

Aluminium is unquestionably a sturdy and malleable metal. However, copper once more excels in both areas. Therefore, when compared to stabilisers with aluminium winding, those with copper winding require less checks and maintenance operations.

• Manufacturing Expenses

Despite being pricey, copper stabilisers use less material and conductor cross-sections. As a result, producing copper stabilisers is less expensive than producing aluminium ones. Additionally, copper stabilisers are more practical because they need:

1. smaller production equipment.

2. fewer storage spaces.

3. labs for quality control.

• Galvanic action

To make a conductive conduit for ions and electrons to pass from one metal to another, galvanic action takes place when two electromagnetically dissimilar metals come into contact. Galvanic actions can occasionally cause contacts to completely lose or partially loosen. In this case, copper stabilisers lose more material to galvanic action than stabilisers made of aluminium.

• Creep level

Aluminum stabilisers are more prone to failure than copper stabilisers under heavy loads or high temperatures because the creep rate of aluminium can reach 25 times that of copper.

I would like to conclude here as I think this suffices your query about which stabilizer is best copper or aluminium. I hope this helps:)
