The complete naming of wires and cables is often complicated, so people sometimes use a simple name (usually a category name) in combination with the model specification instead of the full name, such as "low voltage cable" for all plastic insulated power of 0.6/1kV class. cable. The wire and cable type spectrum is relatively perfect. It can be said that as long as the standard model specifications of the wire and cable are written, the specific product can be specified, but what is its complete name?
The naming of wire and cable products has the following principles:
1. Content included in the product name
(1) Product application or size class name
(2) product structure materials or types;
(3) Important or additional features of the product
Basically named in the above order, sometimes in order to emphasize important or additional features, the features are written before or before the corresponding structure description.
2, the order of structure description
Product structure description from the inside to the outside principle: conductor -->; insulation -->; inner sheath -->; outer sheath -->; armored type.
3, simplified
In the case of no confusion, some structural descriptions are written or abbreviated. For example, aluminum conductors are not allowed in automobile wires and cords, so conductor materials are not described.
Case:
Flame-retardant copper core XLPE insulated steel tape armored PVC sheathed power cable with rated voltage of 8.7/15kV
"Rated voltage 8.7/15kV" - use occasion / voltage level
"Flame retardant" - the characteristics of emphasis
"Copper core" - conductor material
"Crosslinked Polyethylene Insulation" - Insulation
"Steel belt armor" - armor layer material and type (double steel belt gap wrapping)
"PVC sheath" - inner and outer sheath material (the inner and outer sheath materials are the same, save the inner sheath material)
"Power Cable" - the broad name of the product
The corresponding model is written as ZR-YJV22-8.7/15. The model is written as described below.
4. The uppercase of the first letter of Pinyin indicates the type of insulation, conductor material, inner sheath material and structural features. For example, Z stands for paper (zhi); L stands for aluminum (lv); Q stands for lead (qian); F stands for phase separation (fen); ZR stands for flame retardant (zuran); NH stands for fire resistance (naihuo).
5. The number of outer sheaths is represented by numbers and has two digits. No number represents no armor layer, no outer layer. The first digit indicates the armor and the second digit indicates the outer quilt, such as the thick steel armor fiber, which is indicated as 41.
6. The cable type is generally arranged according to the arrangement of the cable structure: insulating material; conductor material; inner sheath; outer sheath.
7. Cable products are indicated by model, rated voltage and specifications. The method is to add the rated voltage, the number of cores and the nominal cross-sectional area after the model number.
