Wire (cable) cross-section by diameter: formula, table

Cable weight is the most important characteristic of a power line, taken into account when carrying out electrical installation work. Expressed in kilograms per kilometer of conductor, it depends on the material from which the conductors are made, their number, and cross-sectional area. Also, this calculation sometimes takes into account such characteristics of cable products as the thickness and material of the insulating layer of its conductive cores and outer sheath.

Application

The VBBShvng cable is installed in stationary power lines designed for transporting and branching energy at a maximum voltage of 1000 V and a frequency of 100 Hz when used in an alternating current network. With direct current, the voltage can reach 2500 V.

The area of ​​application of the conductor is temperate and cold climates, and it can be laid in the ground, reservoirs, and air at an altitude of no more than 4.3 km above sea level. Cables are subject to use:

• in the absence of tensile load;
• in zones B-I (except I-c), B-II and B-IIa;
• in case of high fire danger in construction sites;
• in soil with medium and high corrosive activity, in pipes or other protective elements;
• in the metro;
• at high humidity;
• in open areas.

The VBBShvng power cable can be used for installing horizontal and inclined sections of highways.

According to modern requirements for conductors in terms of fire safety, this product belongs to classes A and B (according to IEC 60332-3). This means that group installation of the product is possible without additional protection devices. The maximum heating of the current-carrying part when operating in emergency mode is 80 degrees; the period of such operation should not exceed eight hours per day and thousands of hours over the entire period. The maximum overload is 15%, and the maximum period for such work is six hours per day and five days for the entire period.

Marking and designation

Most often, when purchasing a conductor, a welder encounters the following designations:

• KOG – specially flexible cable;
• KRPT – rubber-sheathed and insulated cable, portable type, heavy;
• KG – flexible cable.

It is the latter type that is the most popular when carrying out welding work. You should also pay attention to the letter values:

• KG-HL welding cable is used in conditions of low ambient temperatures (down to -60°C);
• KG-T – tropical, intended for use at high temperatures (up to +55°C);
• KNG – non-combustible insulation.

Additional information in the marking - in the form of numbers - shows the number of cores and cable cross-section diameter . Each variety has its own distinctive features.

Acceptance rules

The acceptance rules and testing methods for armored power cable VBBShvng are given in State Standards 24334-80 and 15.309.

Conductors are tested at rated and maximum voltage, the resistance of conductive elements and the screen is checked, as well as the presence of damage on the surface of the product. For testing, 3% of the cable from the produced quantity of products or three construction lengths are selected. Testing, which does not imply destruction of the cable, is carried out for the entire batch of goods.

Welding cable requirements

The welding cable must have high flexibility, strength, as well as moisture and oil resistance. These parameters are common and basic for conductors of various types. In addition, the following important requirements apply:

• welding work can be performed in different environmental conditions, so the wire must be resistant to shock, rupture and aggressive chemical environments ;
• in most cases, the cord is stored wrapped, so it must withstand repeated winding and unwinding, and also be resistant to bending ;
• possibility of use at different temperatures and their fluctuations;
• UV resistance ;
• resistance to mold formations .

There are also requirements regarding design features, which will be analyzed in the next section.

Calculator for calculating cross-section by diameter

To simplify calculations, a calculator has been developed for calculating cable cross-section by diameter. It is based on formulas that can be used to find the cross-sectional area of ​​single-core and stranded wires.

You need to measure the cross-section by measuring the core without insulation, otherwise nothing will work. When it comes to calculating tens and hundreds of values, an online calculator can significantly simplify the life of electricians and electrical network designers due to convenience and increased speed of calculations. It is enough to enter the value of the core diameter, and, if necessary, indicate the number of wires if the cable is multi-core, and the service will show the required wire cross-section.

Analogs

Foreign-made cable and wire products have different markings, which is determined by the regulations of the manufacturing countries. Parameters similar to the characteristics of the VBBShvng cable are typical for the products: YBY-O; YBY-J or Cu/ PVC/ STA/ PVC 0.6/1 kV.

Among domestically produced goods, it is worth highlighting the AVBbShng cable, which differs in the material of the current-carrying conductors. In this case, aluminum is used, the disadvantages of which include reduced strength and elasticity relative to a copper product. When bending this conductor, you should be especially careful, because it is more fragile and breaks when the bending radius is exceeded. In addition, it has low weldability.

Purchasing a wire requires careful preparation, during which it is necessary to establish the voltage in the future circuit, the strength of surges in emergency situations, and the possibility of using the selected cable in vertical sections. Professionals often use different types of conductors depending on the installation site.

Decoding

Decoding VBBShvng indicates its main properties:

• B – fire-resistant PVC coating used as an insulating material;
• B – the presence of armor made of galvanized steel strips, which increases resistance to mechanical stress;
• b – without a pillow;
• Shv – fire-resistant coating with polyvinyl chloride composite, serving as a shell;
• ng – non-flammable (in case of fire, does not support combustion and does not spread it).

The price of the cable depends on the material that was used for its production. The main component of the cost of a conductor is the cost of copper used as the conductive part.

Our prices are the most honest

On this page you can find out the approximate amount of copper or aluminum contained in the cable. To do this, you need to know the number of cores, their cross-sectional area or diameter, as well as the length of the cable.

Please note...calculations obtained as a result of entering data into the table are for informational purposes only and may differ significantly from the final value. This calculator provides theoretical data, which usually differs from actual data.

This may happen for the following reasons:

1. You entered incorrect cable data (number of cores, cross-section or cable length)

2. In cable production there are certain tolerances for underestimating the cross-section of the cores. Many unscrupulous manufacturers often abuse this in order to reduce cable production costs. As a rule, cables with large cross-sections differ from theory by 5-10%. There are some manufacturers selling cable or wire with a cross-section of 0.5-2.5 mm2 with a copper content reduced by 20-30%.

3. The price of copper or aluminum in the cable used in this table is taken from the price table for large cross-section power cable.

Cable weight calculator #1

Determining the approximate cost of a cable for scrap metal based on its technical parameters (cable brand, cross-section and number of cores)

• 1Cut a small piece of cable as shown in the picture
• 2Using a caliper, measure the diameter of one core and enter the value in “mm” (millimeters) in the line “Conductor thickness”
• 3Count the number of individual cores in the “bundle” and enter the value in the “Number of cores” line
• 4Indicate the cable length in meters in the “Enter cable length” line (the more accurately you specify this parameter, the more accurately we can calculate the metal content)

Cable weight calculator #2

Determining the approximate price of a cable based on the percentage of metal content in the cable

• 1Weigh a piece of cable on a high-precision scale and enter the value in window No. 1
• 2Remove the insulation from the cable, freeing it from the PVC sheath and armor.
• 3Weigh pure metal (in this case aluminum) and enter the value in window No. 2
