Wire 50mm² | copper | flexible | single-core | multi-stranded | H07V-K 50 | 1m | black

Single-core wires are also called monolithic wires,
while multi-core wires are flexible wires.

Wires usually have a single conductor covered with an insulating layer.

Cables have several insulated wires, covered with a common sheath.

Conductor properties of wires:

The resistance of copper conductors is lower (0.017Ω) than that of aluminum (0.028Ω),
but copper has better conductivity.
Copper has better electrical and thermal conductivity than aluminum.
Copper wires are more flexible, more resistant to corrosion, and more durable.
Aluminum wires quickly oxidize upon contact with air, forming a film that weakens the contact.
Copper wires carry higher currents than aluminum wires.
Copper conductors are denser than aluminum. Therefore, copper wire is heavier.

The cross-sectional area of wires is chosen according to the power of specific equipment,
for example: for a 1kW load, a 1.57 mm² cross-sectional area of the conductor is required.
For aluminum wires: 5A per 1mm², and for copper wires: 8A per 1mm².
