Extended data
The naming of wire and cable products has the following principles:
1. What is contained in the product name.
Basically, they are all named in the above order. Sometimes, in order to emphasize important or additional features, features are written before or before the corresponding structural description.
2, the order of the structure description
The product structure is described according to the principle from the inside out: conductor-> conductor; Insulation->; Inner sheath->; External sheath->; Armor type. ?
Step 3 simplify
In order not to cause confusion, some structural descriptions are omitted or abbreviated. For example, aluminum conductors are not allowed to be used in automobile wires and flexible cords, so conductor materials are not described.
