Wire And Cable Models


The model and sequence of wire and cable are as follows:

[1: Category, use] [2: Conductor] [3: Insulation] [4: Inner sheath] [5: Structural features] [6: Outer sheath or derivative]-[7: Use characteristics] 1-5 items And the seventh item is represented by a pinyin letter, the polymer material is represented 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 T is written, 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. Wires and cables for electrical equipment and communication cables are not listed, but subcategories or series codes are listed. Item 7 is a mark for various special use 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).
