The aluminum and copper wires

Wiring never complete without wire connections.The higher power consumption in the home grows, the more important is the right mix of the wiring harness, which would provide the requirements for electrical and fire safety.Proper connection of the wires - is the level of contact density and electrochemical metal compatibility, connected wires.

now in many homes still aluminum wiring.Once in this apartment there is an easy task to replace lamps or sockets, and the problem may occur joining aluminum and copper wire .

known that the direct connection of these metals is strictly prohibited and constitutes a flagrant violation.The direct contact of copper and aluminum is unacceptable because of the incompatibility of these metals.Under the influence of moisture is unsafe connection: may cause a fire.

Dry contact, though a little more reliable, but also not safe: he will simply break down more slowly.If such contact is suddenly gets wet, it may be an accident, even with a slight current.

How to combine aluminum and copper wires in such a situation?

There are several ways, here are the main ones according to SAE:

    1. using terminal clamps
    2. By threaded connection
    3. Using a layer of neutral material
    4. Using welding

Perhaps the easiest way is to use a layerneutral material.As a neutral metal acts lead-tin solder .

Make it very simple

  • stationery knife carefully cut and remove the insulation from the wires for about 6-7 cm. Do not put the knife perpendicular, so you can make an incision in a vein wire.It is better to do it at an angle, something like hone pencil.
  • With the help of a soldering iron cover copper wire solder.To do this, we collect on the soldering tip and solder dip in the rosin.After the resin has melted, very quickly conduct a sting on the wire.
  • Confirm that the tin-plated copper wire well.The solder must completely cover the wire.
  • Make twist tin-plated copper and aluminum wires.Good twist should take as a result of about 4 cm.

method is good because it does not require clamps, or if the bolt connection does not fit into the box.

Despite the fact that a simple and quick method, nevertheless, cumbersome if the compound is not a problem - it is better to use a threaded connection, it will be more reliable. threaded connection of wires from copper and aluminum is fairly simple too.For this type of connection, you need to prepare a spring washer, three plain washers and a nut.If the wires have a diameter of 2 mm lived up to, select the screw M4.

  • Remove the insulation around the length of the four screw diameter.
  • We clean the metal to shine and form rings.
  • Dress on the screw spring washer, then a simple washer, then a ring conductor, simple goal, the second conductor ring, washer, nut.
  • screw and screw-contract all to straighten the spring washers and booster for approximately half a turn.

If stranded copper wire, it must first be proludit.Do not forget that such connections should be checked periodically: optimal frequency - once a year.

is strongly recommended to call electricians professionals if you are not confident in their abilities!After working with the electrician is dangerous for health and life!
