P2 Copper Strip Copper Foil Computer Shielded Cable

1. Copper strip copper foil computer shielded cableThe model composition and sequence are as follows:
   [1: Category, purpose] [2: Conductor] [3: Insulation] [4: Inner protective layer] [5: Structural features] [6: Outer protective layer or derivative] [7: Usage features]
   Items 1-5 and 7 are represented by pinyin letters, while polymer materials are represented by the first letter of their English names, with each item consisting of 1-2 letters; The sixth item consists of 1-3 digits.
   The principle of omission in the model:wire and cableCopper is the main conductor material used in the product, so the copper core code T is omitted, except for bare wires and bare conductor products. Bare wires and bare conductor productspower cableClass and electromagnetic wire products do not indicate major category codes, and electrical equipment wires and cables, as well as communication cables, are not listed. However, subcategories or series codes are listed.
   The seventh item is marked with pinyin letters after "-" for various special usage occasions or additional special usage requirements. Sometimes, in order to highlight this item, it is written before 'zui'. Such as ZR - (flame retardant), NH - (fire-resistant), WDZ - (low smoke and halogen-free, enterprise standard), - TH (used in humid and hot areas), FY - (anti termite, enterprise standard), etc.
