Installation cables and wires

Cables and wires are the main electrical material without which electricity is unthinkable. They are used in a variety of applications including power transmission, communication systems, electronics, and more. The electrical properties of the materials used in cables are essential to the proper functioning of electrical systems. Cables often contain conductors of materials such as copper or aluminum, which are good conductors of electrical charge. Installation cables multi-core and single-core cables used to build electrical installations or electrical appliances and machines.

Single wire

• conductor;
• power cable;
• bridge cable;
• solar cables;

Multi-core

• H03VH-H;
• H05VV-F;
• H07RN-F;

Single wire

Information and features of SVT cables

Another popular type of installation cables are SVT - power cables for voltage up to 1000V with a frequency of 50Hz, highly resistant to atmospheric influences and solar radiation. SVT cables can withstand a maximum temperature of 70°C during continuous operation, and up to 160°C during a short circuit within about 5 seconds. The sheath of the core and the general insulation are made of PVC plastic. In installation, this cable can be placed in a corrugated pipe or directly in the ground.

PVV-MB1 cables are the most used cables for building electrical installations and are a flat cable with one, two, three or four copper cores with colored insulation for each. The general insulation of the cable is usually white in color. PVV-MB1 cables are better known among users as bridge cables.

Bridge cables - Laying specifications and applications

This type of cable is flat, which helps to make it easier to lay when directly embedded in a wall. This is done in order to slow down the aging process of the PVC insulation of the cable. Another popular way of laying bridge cables is on wooden surfaces such as gazebos, sheds and cabins. Using nails, the cable is fixed directly on the wooden surface.

What are power cables and what types are there?

Power cables are used to power household and industrial electrical appliances, machines, as well as movable electrical equipment. What is specific about them is that they are flexible and multi-wired, with each wire having colored PVC insulation. The power cords are:

Multi-wire

• H03VH-H type cables - flexible cables with individually insulated copper cores and common sheath (H05VV-F);
• H07RN-F type cables - flexible cables with a small cross-section, we have HVPL-A and HVPL-B, and in the second type we have a common sheath of the insulated copper cores;
• Cables type H05VV-F - cables for electric power - single-wire multi-wire cable with rubber insulation, used in electric arc welding. It is used for making and repairing electric cables;
• Cables powering solar systems - cable resistant to high overheating, UV radiation and various atmospheric influences. Its special polymer insulation with a cross structure, produced by a new technology with electron radiation, provides the cable with a life of over 25 years. under intense UV radiation.
