If today a builder stumbles upon a twist, then he immediately calls it "hack". To some extent, I agree with this, but let's take, for example, Soviet twists, the service life of which exceeded 30 years. And I'm talking about aluminum twists ...
In this article, we will talk about whether there is a place for Soviet twists in the modern world! So, we are trying to figure it out.
You cannot save on reliability! Soviet people had a different opinion
The old Soviet housing, which is commonly called "Khrushchev", is known for its small size, lack of an elevator in the entrances, poor noise and heat insulation.
But let's try to look at them from the other side. I believe that the "Khrushchevs" effectively solved and continue to solve the housing issue. Nowadays, the government promises us affordable housing, but in reality, all these promises turn into an empty phrase. Better a titmouse (a simple apartment) in hand than a crane (imaginary modern apartment) in the sky.
However, we started talking about electrics, let's talk about it and continue.
In Soviet times, the wiring was aluminum; twists were almost always used to connect the wire. Today's rules categorically prohibit doing this, but the twists actually worked, and for many years. What is the reason for this?
Why are Soviet twists banned today?
So, in the modern world it is forbidden to use Soviet life hacks, and here's why:
- 1. Soviet wiring was distinguished by its simplicity, there were no more than 10 connections, in rare cases - 20.
- 2. Electrical appliances in Soviet times consumed several times less power. If earlier the iron needed 500 V, then today - all 2000 V.
- 3. The twists were made no shorter than 5 centimeters, if it was about 3 wires. The more wires, the longer the twist.
- 4. Only qualified electricians were allowed to carry out the wiring. Look at today's vocational school graduates - they cannot be compared with Soviet specialists.
Why is the length of the twists so important?
The main problem with aluminum stranding lies in the presence of an oxide film between the conductors. With a small contact area, the conductors will create a lot of resistance.
If the twist is long, and the power is relatively small (up to 1 kW), then the wires will not overheat. As a result, the service life of such a twist is tens of years. The main thing is that it does not come into contact with combustible materials.
So we got all the inputs to add up the overall picture. It turns out that the Soviet twists worked, since they had a large contact area, a small current was transmitted to them, and they were enclosed in a metal box.
Are all these conditions observed in the modern world? The power of electrical appliances today is much higher, the wires are enclosed in plastic boxes that are highly flammable. And some "craftsmen" do not know how to distinguish aluminum from copper, which is fraught with serious consequences.
Unfortunately, we have practically no chance of repeating the durable, safe Soviet twist. Therefore, you have to use the terminals.
