Cable type indication method and selection precautions

Cable type and order:
1: category, use 2: conductor 3: insulation 4: inner sheath 5: structural feature 6: outer sheath or derivative 7: use characteristics
Items 1-5 and 7 are indicated by pinyin letters, and polymer materials are indicated by the first letter of the English name, each item can be 1-2 letters; the sixth item is 1-3 numbers.
The omission principle in the model: copper is the main conductor material used in wire and cable products, so the copper core code is written in T province, except for bare wires and bare conductor products. Bare wire and bare conductor products, power cables, and electromagnetic wire products do not indicate large class codes, and wire and cable and communication cables for electrical equipment are not listed, but lists small classes or series codes.
Item 7 is a mark for various special occasions or additional special use requirements, and is marked with a pinyin after "-". Sometimes in order to highlight the item, write this item to the front. Such as ZR- (flame retardant), NH- (refractory), WDZ- (low smoke and halogen free, corporate standards), -TH (for hot and humid areas), FY- (anti-termites, corporate standards).
Digitally marked armor layer outer jacket or outer jacket
0 no ---
1 interlocking armored fiber outer cover
2 double-layer steel belt PVC jacket
3 fine round steel wire polyethylene jacket
4 thick round wire
5 wrinkle (rolled) steel strip
6 double aluminum (or aluminum) belt
8 copper wire weaving
9 steel wire weaving
The model number of the cable means:
First, the use code - not marked as a power cable, K is the control cable, P is the signal cable;
Second, the insulation code - Z oil-impregnated paper, X rubber, V polyvinyl chloride, YJ cross-linked polyethylene
Third, the conductor material code - not marked as copper, L is aluminum;
Fourth, inner sheath code - Q lead package, L aluminum package, H rubber sleeve, V polyvinyl chloride sheath
Fifth, the derivative code -D does not drip, P dry insulation;
Sixth, the outer layer code
Seven, special product code -TH wet tropics, TA dry tropics;
Eight, rated voltage - unit KV
Cable type selection precautions
