Do you really know the model of wires and cables?

As we all know, the name of a complete wire and cable is very long, which is very tedious both in writing and reading. For the convenience of many people, they will use letters to represent the name of the cable. In fact, the model of the cable is very learned. These letters, when combined, not only represent the name of the cable, but also reflect the category, use The main structural materials and structural characteristics, as well as the application scenarios, etc. Now let's see how the cable model is represented.

The first letter of wire and cable model indicates the insulation type, conductor material, inner sheath material and structural characteristics.

Use numbers to indicate the composition of the outer layer. If there is no number, it means there is no armor and no outer layer. The first digit represents the armored structure, and the second digit represents the outer covering structure.

The cable models are generally arranged in the following order according to the cables: insulation materials, conductor materials, inner protective layer and outer protective layer.

Cable products are represented by model, rated voltage and specification. The method is to add Arabic numerals indicating rated voltage, number of cores and nominal sectional area after the model.

Let's take an example:

YJLV22-1 3 × 150 aluminum core, cross-linked polyethylene insulation, armored PVC sheath, rated voltage 1KV, three cores, nominal section 150mm ² Power cable.

At the same time, in order to make the model look more concise and beautiful, the model display also adopts the omission of some letters. The most common is to omit the T in the copper conductor cable, and only add the letter L to the model with aluminum conductor.
