Is it possible to connect copper and aluminum wires

The question "Is it possible to connect aluminum wires with copper?" home masters ask not out of idle curiosity. The safety of their operation depends on how accurately all the norms and requirements for working with electric networks are met.

Is it possible to connect an aluminum wire with a copper

When performing repairs related to electrical wiring, very often there is a need to connect conductors made of different materials. In this case, you can use several methods that are easy to use and allow you to get a secure connection.

Screw connection

The first option is a threaded connection of wires, characterized by a high level of reliability. This method is used when connecting conductors with different diameters or with different number of cores. This is the best way to connect several wires at the same time, the number of which depends solely on the length of the screw.

With this method of connecting the wires, they are separated by washers of the appropriate diameter

Terminal connection

The second option is cable clamping. Using standard terminals, it is possible to get the fastest, easiest and highest quality connection without forming rings and isolating sections of the union of different materials. Due to the special design of the terminal block, the risk of contact between bare cables is completely eliminated.

With a simple terminal, only two conductors can be connected directly

One-piece twist

The third option - rivet lived with a sleeve. This method is simple and quite affordable, but involves the use of a special riveting machine and heat-shrink tubing, which allows for reliable and safe isolation of twisting sections. Due to the rich assortment of rivets, which differ in length and diameter, it is possible to independently carry out quick connection of conductors with almost any section.

Riveting wires using a metal sleeve requires the use of a special tool - a crimper or press pliers

With a direct connection of copper and aluminum wires with different linear expansion, they contact with oxide films, which negatively affects the quality of the wiring and its durability. To get the most reliable connection of such cables, you must use special insulating materials or use one of the methods listed above.
