We wrote above that when selecting wires, the focus is on the power of the appliances that will be powered by them, and they also pay attention to other operating factors.
Of course, it is impossible to describe all types of wires, so we will only focus on the most common wires that you see most often in daily life.
1. PBPPg
It is a flat and fairly flexible wire with stranded conductors. It is used where the wire needs to be bent, and used as a wire for sockets or lighting equipment. The voltage is up to 250 V and the frequency is 50 Hz.
2. PBPP
However, the last analogue is a wire with a single-wire copper conductor, the cross section of which can vary from 1.5 to 6mm², and they are on the same plane. These wires are insulated with PVC and are mainly used indoors, although they are also used outdoors.
According to the specifications, it can be used at a temperature not lower than -15 degrees. The rest is similar to the previous version.
3. PPV
This wire is difficult to confuse with other types, because it is easy to identify it by the jumper between the cores. They are made of PVC (just like the insulating material itself). The core wire is a single wire with a cross-sectional area of 0.75 to 5-6. It is used to transmit current with a voltage of up to 450 V. It is used in a wide range of conditions and can also be installed outdoors. You can also mention the APPV line immediately.
As the name suggests, it is characterized by aluminum conductors with a cross-section starting from 2.5mm². In all other respects, it has similar characteristics.
4. APV
The single wire design has a solid aluminum wire with a cross section of 2.5 to 16mm². The cross section of the strand can reach 95. With PVC insulation, the wire can be used under almost any conditions, even under high humidity. Suitable for outdoor use. The analog of AR is PV1. The characteristics are similar, but the core wire is copper.
5. PVS
2-5 copper stranded wires with a maximum of 16mm² can be used in the stranded wire. It can transmit current with a frequency of 50 Hz and a voltage of 380 V. It has high flexibility (and resistance to repeated bending), so it is most commonly used to make wires.
At the same time, it is strongly recommended not to use it as a wire laying inside walls, otherwise it may wear and damage the insulation material. It is also worth mentioning that one of its modifications-PVSU, which has a wider operating temperature range.
6. Ballscrew
A fairly common wire, usually regarded as a power cord for low-power devices or lights. The voltage is 380 V, the current frequency is -50 Hz, with two or three copper stranded wires, and the maximum cross-sectional area is 0.75mm².
