Description：
1. Contents included in product name
(1) Name of product application occasion or size category;
(2) Product structure material or type;
(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 corresponding structure description.
2. Order of Structural Description
The product structure description is based on the principle of from inside to outside: conductor >; insulation >; inner cladding >; outer cladding >; armor type.
3, simplify
Without confusion, some structural descriptions are omitted or abbreviated. For example, aluminium conductors are not allowed in automotive and soft wires, so conductor materials are not described.
Case study:
Nominal voltage 8.7/15kV flame retardant copper core XLPE insulated steel tape armoured PVC sheathed power cable
"Rated Voltage 8.7/15kV"-Use Situations/Voltage Levels
"Flame Retardant": Characteristics of Emphasis
"Copper Core" - Conductor Material
"Crosslinked Polyethylene Insulation" - Insulation Material
"Steel Belt Armouring" - Material and Type of Armouring Layer (Double Strip Clearance Wrapping)
"Polyvinyl chloride sheath" - inside and outside sheath materials (inside and outside sheath materials are the same, save writing inside sheath materials)
"Power Cable" - The Name of Products
The corresponding model is written as ZR-YJV22-8.7/15. See the description below.
4. Use the capitalization of the first letter of Chinese Pinyin to indicate the insulation type, conductor material, inner cladding material and structural characteristics. For example, Z stands for paper (zhi); L stands for aluminium (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. Numbers are used to represent the composition of the outer protective layer, which has two digits. Numerous numbers represent no armoured layer, no outer cover. The first digit denotes armor and the second digit denotes outer cover, such as the outer cover of thick steel wire armor fibers, is 41.
6. The order of cable type according to cable structure is: insulating material; conductor material; inner protective layer; outer protective layer.
_Cable products are expressed by model, rated voltage and specifications. The method is to specify the rated voltage, core number and nominal cross-section area after the model.
