Wire and cable products are named after the following principles:

1, the content included in the product name

(1) product application or size class name

(2) product structure material or type;

(3) important features or additional features of the product

Basically in the order described above, sometimes in order to emphasize important or additional features, the characteristics written to the front or the corresponding structure before the description.

2, the order of structural description

Product Structure Description From the inside to the outside of the principle: conductor -> insulation -> inner protective layer -> outer sheath -> armored type.

3, simplified

In the absence of confusion, some structures describe provincial or abbreviated, such as automotive lines, which are not allowed to use aluminum conductors, and do not describe conductor materials.

Example:

Rated voltage 8.7 / 15kV flame retardant copper core XLPE insulated steel tape armored PVC sheathed power cable

"Rated voltage 8.7 / 15kV" - use the occasion / voltage level

"Flame retardant" - emphasizes the characteristics

"Copper core" - conductor material

"Cross - linked polyethylene insulation" - Insulating material

"Steel tape armor" - armor layer material and type (double steel band gap wrap)

"PVC sheathed" - inside and outside the jacket material (inside and outside the jacket material are the same, write the inner jacket material)

"Power Cable" - the name of the product

Corresponding model is written as ZR-YJV22-8.7 / 15, the type of writing see the following description.

model:

The composition and order of the wire and cable are as follows:

[1: Category, use] [2: conductor] [3: insulation] [4: inner layer] [5: structural features] [6: outer sheath or derived] - [7:

1-5 and 7 are indicated by phonetic alphabet, and the polymer material is indicated by the first letter of the English name. Each item can be 1-2 letters; item 6 is 1-3 digits.

Model in the omission principle: wire and cable products in the copper is the main use of the conductor material, so the copper code T write, but bare wire and bare conductor products except. Bare wires and bare conductor products, power cables, electromagnetic wire products do not indicate the large class code, electrical equipment, wire and cable and communication cable category is not listed, but set out small class or series code.

Item 7 is a special use of the occasion or additional special use of the requirements of the mark, in the "-" after the alphabet letters. Sometimes in order to highlight the item, write this to the front. Such as ZR- (flame retardant), NH- (refractory), WDZ- (low smoke and halogen, enterprise standard), - TH (for hot and humid areas), FY- (anti-termite, enterprise standard).
