Cable Model

Composition and order

The model composition and sequence of the wire and cable are as follows: [1: category, purpose] [2: conductor] [3: insulation] [4: inner sheath] [5: structural features] [6: outer sheath or derivative]-[ 7: Use characteristics]

Items 1-5 and 7 are represented by pinyin letters, and polymer materials are represented by the first letter of the English name, and each item can be 1-2 letters; item 6 is 1-3 numbers.

Common code

Purpose 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 package), L- (aluminum package), H- (rubber sheath), V- (polyvinyl chloride sheath), the inner sheath is generally not marked;

Outer sheath code-V- (polyvinyl chloride), Y- (polyethylene power cable);

Derived code-D- (non-drip), P- (dry insulation);

Special product codes-TH- (humid tropical zone), TA- (dry tropical zone), ZR- (flame retardant), NH- (fire-resistant), WDZ- (low smoke and halogen free, corporate standard).

Omission principle

The principle of omission in the model: Copper is the main conductor material used in wire and cable products, so the copper core code is written as T, except for bare wires and bare conductor products. Bare wires and bare conductor products, power cables, and electromagnetic wire products do not indicate major category codes, and electrical equipment wires and cables and communication cables are also not listed, but subcategory or series codes are listed.

Item 7 is a mark for various special use occasions or additional special use requirements, marked with a pinyin letter after "-". Sometimes in order to highlight this item, write this item to the top. Such as ZR- (flame retardant), NH- (fire-resistant), WDZ- (low smoke and halogen-free, corporate standard), TH- (for hot and humid areas), FY- (termite-proof, corporate standard), etc.
