| Origin of wire and cable names |
| 2011-5-27 17:21:38 |
The names of wires and cables are more complicated, so people often use abbreviations instead of full names. For example, "high-voltage power cables " represent all plastic insulated sheathed power cables with voltage levels from 1kV to 35KV. The type spectrum of wires and cables is relatively complete. Generally speaking, as long as they write down their standard model specifications, specific products can be identified.
Let's take a look at the specific names of wires and cables .
The product naming of wire and cable has the following principles:
1. What's included in the product name (1) Product applications (2) Product structural materials (3) Product characteristics, sometimes in order to emphasize the characteristics of a certain cable, write the characteristics in front.
2. In the simplified form, some structural descriptions are abbreviated without causing confusion. For example, aluminum conductors are not allowed in automobile wires and flexible wires, so the conductor materials are not described.
Here are specific examples:
Such as rated voltage 8.7 / 15kV flame retardant copper core XLPE insulated steel tape armored PVC sheathed power cable
"Rated voltage 8.7 / 15kV" indicates the application / voltage level
"Flame retardant" is both an emphasized feature
"Copper core" refers to the material of the inner conductor
"Crosslinked polyethylene insulation" means insulating material
"Steel belt armoring" —— Material structure of armor layer
"Polyvinyl chloride sheath"-inner and outer sheath materials (if the inner and outer sheath materials are the same, save the inner sheath material)
"Power cable" —— The type of the cable product corresponding to the description of the cable is written as ZR-YJV22-8.7 / 153,
Wire and cable structure description The cable structure description follows the principle from the inside to the outside: conductor-> insulation-> inner sheath-> outer sheath->> armored type.
