Naming principles and cases:

The following are the same as the "

The complete naming of wire and cable is usually more complex, so people sometimes use a simple name (usually a category name) in combination with the model name to replace the full name, such as "low voltage cable" on behalf of 0.6 / 1kV level of all plastic insulated power cable. Wire and cable type spectrum is more perfect, it can be said, as long as the written wire and cable standard model specifications, you can clear the specific product, but its complete name is what?

The following are the same as the "

Wire and cable products are named after the following principles:

The following are the same as the "

1, the content included in the product name

The following are the same as the "

(1) product application or size class name

The following are the same as the "

(2) product structure material or type;

The following are the same as the "

(3) important features or additional features of the product

The following are the same as the "

Basically in the order described above, sometimes in order to emphasize important or additional features, the characteristics written to the front or the corresponding structure before the description.

The following are the same as the "

2, the order of the structure description

The following are the same as the "

Product Structure Description From the inside to the outside of the principle: conductor -> insulation -> inner protective layer -> outer sheath -> armored type.

The following are the same as the "

3, simplified

The following are the same as the "

In the absence of confusion, some structures describe state-written or abbreviated, such as automotive lines, and aluminum conductors are not allowed in the cord, so the conductor material is not described.

Case:

The following are the same as the "

Rated voltage 8.7 / 15kV flame retardant copper core XLPE insulated steel tape armored PVC sheathed power cable

The following are the same as the "

"Rated voltage 8.7 / 15kV" - use the occasion / voltage level

The following are the same as the "

"Flame retardant" - emphasizes the characteristics

The following are the same as the "

"Copper core" - conductor material

The following are the same as the "

"XLPE insulation" - insulating material

The following are the same as the "

"Steel tape armor" - armor layer material and type (double steel belt gap around the package)

The following are the same as the "

"PVC sheathed" - inside and outside the jacket material (inside and outside the jacket material are the same, the provincial write jacket material)

The following are the same as the "

"Power Cable" - the name of the product

Corresponding model is written as ZR-YJV22-8.7 / 15, the type of writing see the following description.

The distinction between wires and cables

The following are the same as the "

In fact, "wire" and "cable" and there is no strict boundaries. Usually less than the core number, the product diameter is small, the structure of a simple product called the wire, there is no insulation called bare wire, the other known as the cable; conductor cross-sectional area larger (more than 6 square millimeters) known as large wire, Small (less than or equal to 6 square millimeters) is called a small wire, insulated wire, also known as cloth wire.

The composition and order of the wire and cable are as follows:

1-5 and 7 are indicated by phonetic alphabet, and the polymer material is indicated by the first letter of the English name, each of which may be 1-2 letters; item 6 is 1-3 digits.

The following are the same as the "

Model of the principle of omission: wire and cable products, copper is the main use of the conductor material, so the copper code T write, but bare wire and bare conductor products except. Bare wires and bare conductor products, power cables, electromagnetic wire products do not indicate a large class code, electrical equipment, wire and cable and communication cable category is not listed, but set out small class or series code.

The following are the same as the "

Item 7 is a special use of special occasions or additional special requirements of the mark, in the "-" after the alphabet letters. Sometimes in order to highlight the item, write this to the front. Such as ZR- (flame retardant), NH- (refractory), WDZ- (low smoke and halogen, enterprise standard), - TH (for hot and humid areas), FY- (anti-termite, enterprise standard) and so on.
