It is impossible to conduct electricity from the pole to the house without a self-supporting insulated wire. It is he who is used for overhead laying of power lines. SIP cable and the wire are often confused or considered the same, but this is not the case. The wire does not have additional protection (insulation and armor), while the cable does. Therefore, technically it is not. How to choose it correctly?
Types and areas of use
SIP in no case should be installed at home, since this case requires an insulated cable. It is better to pull the wire to the shield outside. Its main purpose is to connect electricity to a private house. Additionally, self-supporting insulated wire can be used to form a branch from the power line.
There are 3 types of model:
- With bare neutral
- Isolated neutral
- Self-supporting.
Wires for overhead lines are made of steel, aluminum alloy, copper, aldrey. The insulation is made of polyethylene, which is resistant to ultraviolet and ozone. The multi-wire conductors are rounded and the neutral conductor is twisted around the core.
Where to buy, how to choose
You can buy a cable at any base or store of electrical materials. But you can do it easier - find and order on the Internet. The site tdok.com.ua offers a wide range of carrier wires. You can find SIP - 3, SIP - 4, SIP - 5 with different sections. Mostly they take SIP - 4, cable for the street 16 sq mm.
SIP -1 - represents from 1 to 4 phase conductors. Can be purchased to enter the house, laying around the building.
1) SIP - 2 - insulation comes from light-stabilized polyethylene. Withstands high temperatures up to 90 degrees.
2) SIP - 3 - suitable for 6-35 kV transmission lines.
3) SIP - 4 - no carrier conductor, but there are phase conductors up to 4 pcs.
4) SIP - 5 - a mixture of cables 2 and 4.
The presence of a letter after the mark indicates that there are operational and design differences. These differences differ in parameters. When choosing a specific model, one must proceed from the correspondence of the characteristics, the individual requirements of the consumer and the method of installation. At the same time, to lay the cable, you do not need to be professional, you can do it at home.
SIP wires are much superior to AC. They are resistant to high loads, can withstand different temperatures, are fire safe and block unauthorized connections. Choose the best!
