Power cable model description

Power cable model description

Power cables are also divided into models. Let's take a look at how power cables are distinguished, so that we can better use power cables and give full play to its advantages.

Model of power cable

1. Use the capital letter of the first letter of Chinese Pinyin to indicate the type of insulation, conductor material, inner sheath material and structural characteristics. For example, Z represents paper (zhi); L represents aluminum (lv); Q represents lead (qian); F represents phase separation (fen); ZR represents flame retardant (zuran); NH represents fire resistance (naihuo).

2. Use numbers to indicate the composition of the outer sheath, with two digits. No number means no armor layer, no outer quilt. The first digit represents the armor, the second digit represents the outer quilt, for example, the outer layer of the thick steel wire armored fiber is represented as 41.

3. The cable models are generally arranged in the following order according to the cable structure: insulating material; conductor material; inner sheath; outer sheath.

4. Cable products are indicated by model, rated voltage and specification. The method is to add a description of rated voltage, number of cores and nominal cross-sectional area after the model.
