The full name of wire and cable is usually more complex, so people sometimes use a simple name (usually a class name) name to replace the complete model specifications with, such as "low-voltage cable" on behalf of all plastic 0.6/1kV class insulation power cable. Electric cable Xingpu relatively perfect, can say, as long as the write cable standard specifications, can to specific products, but its full name is what?
Naming principles
Nomenclature of wire and cable products have the following principles:
Including the contents of 1, in the product name
(1) the product applications or size class name
(2) the product structure material or type;
(3) the important feature of products or additional features
Basically according to the order of naming, sometimes in order to highlight important or additional features, will feature wrote front or corresponding structure description.
2, describe the sequence structure
According to the product structure description from the inner to the outer conductor insulation principle: > > inner protecting layer - > layer of protection -- > armor types.
3, simplified
In does not cause confusion, some structure description, write or abbreviations, such as aluminum conductor does not allow car line, cord, so do not describe the conductor material.
Case:
Rated voltage of 8.7/15kV flame retardant copper core XLPE insulated PVC sheathed power cable
(too long! )
"Rated voltage 8.7/15kV" -- occasions / voltage grade
"Characteristics of flame retardant" -- Emphasis
"Copper" -- conductor material
"Cross-linked polyethylene insulation insulation materials --"
"Steel tape armored" -- the armoring layer material and type (double belt gap wrapped)
"PVC" -- inner and outer sheath material (inner and outer sheath material uniform, write inner sheath material)
"Power cable" -- category name
The corresponding models are written as Zr-YJV22-8.7/15, type of writing see note below.
