Specifications AVBbShv cable

AVBbShv Cable has established itself as a very strong, durable and relatively inexpensive type of conductor that can be used in difficult conditions.Next, we consider the most questions you may have: scope, decoding and specifications AVBbShv cable.We also give advice on choosing the best products that you do not become a victim of counterfeiting.

How to decipher the markings?

Photo armored aluminum conductor

Thus, decoding marking AVBbShv cable as follows:

  • A - aluminum conductors;
  • B - PVC core insulation (heat resistant plastic);
  • B - armored protection and is represented by two steel bands;
  • b - protective cushion between the armor and the current-carrying conductor is absent;
  • IIIB - outer sheath of extruded hose is PVC material.

As you can see, the protective cover is quite robust, which allows to lay the line at no additional protection against rodents and mechanical damage.

Features

AVBbShv Cable structure represented by the following elements: Construction products

Where:

  1. busbar conductor made of aluminum (which can be from 1 to 5).Once there can be both single-wire and multi-wire.
  2. insulation layer of PVC plastic.As you can see in the picture, the insulation is color-coded according to GOST standards.
  3. Additional belt insulation provided by PVC tape.
  4. Book a layer of two steel tapes.
  5. protective covering of bitumen (used if the cross-section of more than 6 mm2).
  6. insulating layer of polyethylene terephthalate film (the same applies, if the diameter of more than 6 mm2).
  7. outer sheath power cable AVBbShv PVC hose.

Terms Another, no less important point on which you want more detail.To guide you to have served more than one year (but as said plant manufacturer, this figure may reach 30 years), we strongly recommend that you read the following operating conditions AVBbShv cable:

  • operating temperature from -50 to + 50 ° C;
  • maximum permissible temperature of the conductors of not more than 70 ° C;
  • maximum temperature of living in the event of a short circuit - 160 ° C (with no more than 5 seconds);
  • temperature wiring work is not lower than -15 ° C;
  • frequency of the alternating electric current 50 Hz;
  • rated voltage of 660 V and 1000 V;
  • cable insulation AVBbShv flame retardant with a single laying (according to IEC 60332-1);
  • product life of 30 years, and the warranty period is 5 years;
  • duration of emergency operation no more than 8 hours a day, while for the entire service life time should not exceed 1000 hours.

As you can see, the technical characteristics of the cable AVBbShv have no particular restrictions on the temperature conditions, so it can be easily used in both industrial and domestic purposes.

more details you can read the description of the characteristics (cross-section, the outer diameter and weight) in the table: The weight and cross-section (round wire) The weight and cross-section ( core sector )

Scope

And one of the questions you may have: where is applied thisa kind of electric cable.Appearance

According to the standards, the scope AVBbShv following:

    • Climate: tropical, arid, temperate;
    • explosion and fire facilities;
    • humid zones - collector, tunnels, mines, etc., and the track can be both horizontal and inclined;
    • in the air if there is a risk of mechanical damage to the power supply line;
    • in the ground only when the cable during operation is subjected to tensile stresses.

As you can see, the scope AVBbShv quite extensive and has no significant restrictions.We draw your attention to a very important caveat: If the marking is present the letter "T" (tropical), it means the product has a high resistance to shock mold.

As for domestic use, the power cord AVBbShv very well established for laying underground line to the house (as shown in photo).Despite the fact that the aluminum conductor products (try not to use them because of the fragility), a popular conductor when installing the wiring in the house and in the country.High demand associated with the low cost of the product.In contrast to the more reliable the copper analogue - VBbShv, aluminum is 3-4 times cheaper, saving a decent amount of money.Electrical installation in the ground

If you decide to use this option in their own cable wiring, be sure to perform the calculation of the current capacity and the cable cross-section to cores were able to withstand the load current from the electrical appliances.

How to avoid becoming a victim of counterfeiting?

So, the last of the points on which I would like to dwell in more detail - the choice of quality products AVBbShv armored cable type.Today there are many companies involved in the production of electrical products, including power conductors.The problem is that a large part of them saves on material that affects the indicators such as the actual size of living and quality of materials.

For example, if you need a cable estimated minimum section of 16 mm2, it is not certain that you buy a product with such a value.In most cases, the diameter of the living less than 10-15%, which negatively affects the permissible current loads.As a result, after the wiring may occur wiring failure, short-circuit and therefore time-consuming repairs.The diameter of the conductors

To avoid this, be sure to give preference to quality manufacturers AVBbShv cable that is recommended on the set of forums, which, in turn, have a lot of positive reviews.

Among these producers should be made:

  1. Kolchugino
  2. Amur Cable Plant
  3. Energokabel
  4. Sevkabel
  5. Pskovkabel

In addition, we recommend you to purchase independently verify the product using one of the methods of determining the diameterI lived.If the values ​​match, and the appearance of the cable is not in doubt, you can safely buy it.

That's all that I wanted to talk about the conditions of use, manufacturers and technical characteristics AVBbShv cable.We hope that the information was interesting and useful for you.If you have any questions, ask them to our experts in the "Q & A" category!
