Specifications Cord SHVVP

click fraud protection
cord SHVVP very popular today and very often used in the home.This is due to the relatively low price of the conductor and at the same time good workmanship.Next, we consider in detail the technical specifications SHVVP, transcript labeling and no less important - area of ​​application in everyday life.

How to decipher the markings?

Key characteristics of the insulation

So, let's talk first of all about the fact that all the same abbreviation means SHVVP: wire or cable?Many people when searching for information about this conductor connect him with these prefixes.In fact, the acronym stands for:

  • W - Cord;
  • In - shell lived from PVC;
  • V - the outer shell of polyvinyl chloride;
  • P - flat.

As you can see, this type of conductor is neither cable or wire.To continue you can immediately identify the acronym that in front of you for the type of conductor, be sure to check with a transcript labeling wires and cables!

Features

Once you have learned, decoding marking SHVVP cord, we recommend to get acquainted with its main design features.The appearance of the three-wire electrical cord

Thus, the electrical cord has the following structure:

  1. the conductors of copper, of circular cross section, stranded (clearly visible in the photo).
  2. Number of cores 2 or 3.
  3. Location lived - in parallel with each other.
  4. color-coded according to GOST: nil blue, brown phase.If a three-wire power cord (for example, SHVVP 3 * 1.5), the isolation of the third core is colored in yellow-green color and is used as a ground.

Basic parameters

basic operational, in other words - technical specifications SHVVP represented by the following values:

  • rated voltage - 220/380 Volt;
  • nominal frequency of the alternating current oscillations - 50 Hz;
  • peak voltage (up to 15 minutes) - 2000 volts;
  • cross section 0.35 to 2.5 mm2;
  • life of 6 to 15 years;
  • warranty period of 2 years;
  • electrical resistivity of 1 km cable - no more than 270 ohms;
  • operating temperature (operating) - from -40 to + 40 ° C;
  • installation is permitted at ambient temperatures from -10 to + 30 ° C;
  • minimum bending radius leads - 30 mm2;
  • current load (continuous current) - depends on the section of wires (for example, the size 2 * 0.75 mm2 is 6 Ampere).
  • weight from 0,026 to 0,049 kg per 1 meter of length.

As you can see, the characteristics SHVVP allow you to use the cord with electrical work, both on the street and indoors.About where applicable the type of conductor in relation to the house, and we'll talk further.

Scope

Due to the fact that the cross section SHVVP cord often does not exceed 2.5 mm2, it can not be used to connect a high-power electrical appliances.Despite the fact that the maximum cross section allows you to connect via SHVVP some electrical power 1-2 kW, most often at home are the following cable sizes: 2 * 0.5;2 * 0.75;2 * 1.5;3 * 0.75;3 * 1.5.Connecting spotlights

As a rule, the scope of the cord SHVVP following:

  1. used to connect low-power appliances: kettle, desk lamp, radio, etc.Some craftsmen make "carry" with the help of the electric wires.If you suddenly decided to make an extension cord with your hands, it is better to select a more reliable analog - wire PVA.
  2. applied when installing lighting, such as street and indoor.In my practice, many times met with the cord markings that connect LED strip with power supply.


As you can see, the use of SHVVP not universally applicable, which is connected with a small wire diameter.At home, we recommend to use a cord with such markings are not to the entire wiring and only the installation of lighting the rooms!

Manufacturers

Well, the last thing you should tell - what are the manufacturers SHVVP cord.To date, the production of the conductor engaged such plants as "Verhneoksky cable factory" Sevkabel "Energokabel", "telecommunications cable" and other leading companies.Packaged Bay Photo

in quality, according to customer reviews, this 4-ka producers fed often.If you suddenly doubted the quality of the products, we are sure to independently determine the cable cross-section to ensure compliance with GOST standards!
