This section describes common specifications of aluminum cable

From the model of aluminum wire, the meaning of each letter in the model, letter B - fixed laying; . X - rubber insulation. L - Aluminum core (copper core without letters). W - Neoprene sheath. Y-polyethylene sheath. Such as: BXW - copper rubber insulated neoprene sheathed wire; BLXW -- Aluminum core rubber insulated Neoprene sheathed wire.

Distinguish from the core material, the core of aluminum wire is aluminum material, the color is white. In ACTUAL life, you can directly strip a small section of wire core to see the color to distinguish copper wire or aluminum wire (generally won't have manufacturers posing as aluminum wire with copper wire, the cost is there).

Now some aluminum wire will be online core surface coated with a layer of yellow material, commonly known as copper aluminum wire, looks yellow. But scratch off the top aluminum wire and it will appear white; The aluminum flame is white when burned with a lighter.

According to the material, there are aluminum wire and alloy aluminum wire. According to the use is divided into industrial aluminum wire and process aluminum wire. Aluminum wire for industrial use meets or exceeds ASTM (American Code for Materials and Tests) -B209 (sheet), B211 (bar) and EN 485:2003 standards.

Common specifications and models of aluminum wire are: 1050, 1060, 1070, 1100, 2011, 2017, 2A16, 2A02, 2024, 3003, 3005, 3A21, 4A01, 5003, 5005, 5052, 5056, 5083, 6061, 6063, 6065, 7003, 7005, 7050, 7075, 8011, etc.

The difference between aluminum wire and copper wire: copper wire and aluminum wire interception volume is different, aluminum wire price is relatively cheaper; Lighter weight; However, the mechanical strength of aluminum wire is poor, and it is very easy to oxidize at the end of the connection wire. After the oxidation of the connection wire, there will be heating phenomenon, and the internal resistance of copper wire is small. Aluminum wire has greater internal resistance than copper wire, but it dissipates heat faster than copper wire. The main is different current carrying capacity and mechanical strength.
