Cable type representation and selection precautions

Cable type and order:

1: Category, use 2: Conductor 3: Insulation 4: Inner cover 5: Structural features 6: Outer sheath or derived 7: Use characteristics

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

Model of the principle of omission: wire and cable products, 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 a 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 special occasions or additional special 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) and so on.

The cable model means meaning:

First, the use of code - not marked as power cable, K for the control cable, P for the signal cable;

Second, the insulation code-Z oil-impregnated paper, X rubber, V polyethylene, YJ cross-linked polyethylene

Third, the conductor material code - not marked as copper, L for the aluminum;

Four, the inner layer of the code-Q lead, L aluminum package, H rubber sets, V PVC jacket

5, derived code-D no drip, P dry insulation;

Sixth, the outer layer code

Seven, special product code-TH wet tropical, TA dry tropical;

Rated voltage - unit KV
