Specifications armored cable VBbShv

How abbreviation stands for?

first thing need to start - deciphering marking VBbShv.According to generally accepted standards, this abbreviation means the following:

• «B» - internal insulation of polyvinyl chloride (PVC);
• «Bb» - booking is made of steel strips;
• «IIIB" - the outer shell is represented PVC hose.

exist cable modification also with prefixes "-ng", which means - flame retardant and "ng-LS», in addition to the conductor almost does not emit smoke.

Another important point - before the label is not the letter "A", which means copper conductor.

design

consider what is in the power cord VBbShv on picture:

addition should specify the following design features of the product:

1. strands of copper, may be stranded, single-wire, as well as sectoral or circular.
2. insulating layer of PVC.Colour insulation corresponds to the standard color-coded wires.Wrapping is also made of PVC.
3. The two layers of steel belts used as armor.We draw your attention to the fact that the top layer is placed so as to cover the joints of the lower.
4. protective outer sheath made of PVC hose.

Worth also view the video, which clearly shows that this is an armored electrical cable:

With design figured out, now we look at the technical characteristics VBbShv.

Basic parameters

specifications armored power cable VBbShv:

• operating voltage 0,66-3 kW and 1-3 kW;
• nominal frequency of 50 Hz;
• operating temperature from -50 ° C to + 50 ° C, the maximum temperature should not exceed + 70 ° C;
• allowed gasket at temperatures below -15 ° C;
• minimum bend radius of 7.5 outer diameter for multi-core cable, 10 for single-core, single-core 15 for the modification VBbShng;
• life of 30 years, while the warranty period of 5 years.
• construction length is 450 meters, if the section is not more than 16 mm2, 300 meters and 25-70 mm2 and 200 meters at the cross-section of more than 95 mm2.

As for the cross-sections VBbShv, as well as the outside diameter and weight, all of these characteristics, we have provided in the tables:

660 Volt

1000 Volt

6000 Volt

Scope

Single core armored cable can be used for power transmission in DC.As for stranded embodiment, it is most often used in the following cases:

1. If you want to carry out the wiring in the ground, tunnels, shafts or trenches;
2. When installing the wiring on the surface, but only if it will not be subjected to significant stretching efforts.
3. Outdoors, if there is a danger of mechanical damage, but subject to paragraph 2.

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

Manufacturers

Today many who produces copper cable VBbShv, but not to become a victim of forgery, is recommended to give preference to the following factory:

• Kolchugino;
• Kavkazkabel;
• Sevkabel;
• Pskovkabel;
• Kamkabel;
• Energokabel;
• Uralcable.

have data producers VBbShv best quality products.Many professionals trust these factories and leave positive feedback about the reliability of cable products.If you doubt that you purchased the conductor does not meet the standards, it is recommended to check the thickness of the conductors and insulation.To learn how to determine the cable cross-section, we described in the relevant article!

That's all that I wanted to tell you about the technical characteristics VBbShv cable.Hopefully, now you know where to apply and how to decipher the conductor!
