Composition and Order
The model composition and sequence of wires and cables are as follows:
1: Category, use]
[4: inner sheath]
[5: Structural features]
[6: outer sheath or derivative]
[7: Using Features]
Items 1-5 and 7 are represented by pinyin letters, polymer materials are represented by the first letter of the English name, each item can be 1-2 letters; item 6 is 1-3 numbers.
Use code - not marked as power cable, K- (control cable), P- (signal cable);
Conductor material code - not marked as copper (can also be marked as CU), L- (aluminum);
Inner sheath code - Q- (lead clad), L- (aluminum clad), H- (rubber sheath), V- (polyvinyl chloride sheath), the inner sheath is generally not marked;
Outer sheath code - V- (polyvinyl chloride), Y- (polyethylene power cable);
Derivative code - D- (no drip), P- (dry insulation);
Special product codes - TH- (wet tropical), TA- (dry tropical), ZR- (flame retardant), NH- (fire resistance), WDZ- (low smoke and halogen free, enterprise standard).
The principle of omission in the model: copper is the main conductor material used in wire and cable products, so the copper core code T is omitted, except for bare wires and bare conductor products. Bare wires and bare conductor products, power cables, and electromagnetic wire products do not indicate the major category code, and electrical equipment wires and cables and communication cables are also not listed, but the small category or series code is listed.
Item 7 is a mark for various special use occasions or additional special use requirements, marked with pinyin letters after "-". Sometimes in order to highlight the item, this item is written to the front. Such as ZR- (flame retardant), NH- (fire resistance), WDZ- (low smoke halogen free, enterprise standard), TH- (for use in humid and hot areas), FY- (termite prevention, enterprise standard), etc.
