Technical characteristics of armored cable VBBSHV

How is the abbreviation deciphered?

The first thing you need to start with is the decoding of the VBBSHV marking. According to generally accepted standards, this abbreviation means the following:

• "B" - internal insulation from polyvinyl chloride (PVC);
• "BB" - the reservation is made of steel strips;
• "Shv" - the outer shell is represented by a PVC hose.

There are also modifications of the cable with the prefix "-ng", which means it does not spread combustion and "ng-LS" in addition to this, the conductor practically does not emit smoke.

Another important point - before the marking, the letter “A” is missing, which means that the cores are copper.

Design

Consider what the VBBSHV power cable in the picture consists of:

In addition, the following design features of the product should be indicated:

1. The veins are copper, can be multi-wire, single-wire, as well as sector or round.
2. PVC insulating layer. Insulation color is standard color marking wires. The belt insulation is also made of polyvinyl chloride.
3. As armor, two layers of steel tapes are used. We draw your attention to the fact that the upper layer is laid in such a way as to overlap the joints of the lower.
4. Protective outer sheath made of PVC hose.

We also recommend watching a video that clearly shows what this armored copper cable is:

We figured out the design, now consider the technical characteristics of VBBSHV.

main parameters

Characteristics of the armored power cable VBBSHV:

• operating voltage 0.66-3 kV and 1-3 kV;
• rated frequency 50 Hz;
• operating temperature from -50 ° С to + 50 ° С, while the maximum temperature should not exceed + 70 ° С;
• laying is allowed at a temperature not lower than -15 ° C;
• minimum bending radius is 7.5 outer diameters for multi-core cable, 10 for single-core, 15 for single-core with VBbShng modification;
• service life of 30 years, while the warranty period of operation is 5 years.
• construction length is 450 meters, if the cross section is not more than 16 mm², 300 meters at 25-70 mm² and 200 meters with a cross section over 95 mm².

As for the cross sections of VBBSHV, as well as the outer diameter and mass, we provided all these characteristics in the tables:

Application area

Single-core armored cables can be used to transmit electricity in DC circuits. As for the multi-core version, it is most often used in the following cases:

1. If needed conduct electrical wiring in the ground, tunnels, mine or trenches.
2. When mounting wiring on the surface, but only if it is not subjected to significant tensile forces.
3. Outdoors, if there is a risk of mechanical damage, but subject to paragraph 2.

At home, the cable is used if you need to conduct electricity from the house to the garden buildings underground. The only reason it may not be used is the high price. In this case, it is recommended to use a cheaper armored analogue with aluminum conductors and similar characteristics - cable AVBBSHV.

Manufacturers

To date, many who produce VBBSHv copper cable, however, in order not to become a victim of fake, we recommend giving preference to the following manufacturers:

• Kolchuginsky plant;
• Caucasus cable;
• Sevcable;
• Pskovkabel;
• Camcable;
• Power cable;
• Uralcable.

These manufacturers VBBSHV the highest quality products. Many professionals trust these plants and leave positive feedback on the reliability of cable products. If you doubt that the conductor you bought does not meet the standards, we recommend checking the thickness of the current-carrying conductors and insulation. About, how to determine the cable cross section, we told in the corresponding article!

That's all I wanted to tell you about the technical characteristics of the VBBSHV cable. We hope you now know where it is used and how to decrypt this conductor!
