The model composition a∞★☆≠nd sequence of wires®&Ω and cablesare as follows: 　　

[1: Category, purpose] [2: Con• πductor] [3: Insulati‌σon] [4: Inner protective layer] [£&→↔5: Structural features] [6: Outer pro&☆tective layer or derivative] [7: Use λ♠♦of special wire 2 cha≥πσracteristics]

Items 1-5 and 7 are represented by pinyσγ"↓in letters, while polymer material✔∞s are represented by the first let¥®↕ter of their English names, wit✔£←<h each item consisting of 1-2 letters; ♠≠δ₩The sixth item consists±≈ of 1-3 digits.

The omission principle in Gua↕®≥​ngdong Cable Factory models: Co§♣pper is the main condu™®±ctor material used in wire and cable≥÷ products, so the copper core cod >♥e T is omitted, except for bare wire ‌ ∞s and bare conductor>≈☆ products. Bare wires and bare ∏&↓conductor products, power ×"✔cables, and electromagnetic wir£€∑Ωe products do not indicate majoφπ γr category codes. Electrical equip↓&ment wires and cables, as∏♣↕€ well as communication cables, aφ₩re also not listed, but sub categoσ€©ry or series codes are specified.

The seventh item is marked with pinyin ​'letters after "-" for various special↕↕₽≠ usage occasions or addi↔Ωβ‍tional special usage requir"∏Ωements. Sometimes, in  •order to highlight this¶™' item, it is written aα÷δt the beginning. Such as ZR - (∑™flame retardant), NH - (f★∞ire-resistant), WDZ - (♠≥low smoke and halogen-free, enterprise ק ‍standard), - TH (used in humid✔☆<✘ and hot areas), FY - (anti termit≤∑¥e, enterprise standard), e♦ ®™tc.
