Industry summary wire and cable model description and use

Items 1-5 and 7 are indicated by pinyin letters, and polymer materials are represented by the first letter of the English name. Each item can be 1-2 letters. The sixth item is 1-3 numbers.

The omitted principle in the model: Copper is the main conductor material used in wire and cable products, so the copper core code is written by T, except for bare wires and bare conductor products. Bare wire and bare conductor products, power cable products, and magnet wire products do not indicate major codes. Wire and cable and cable for electrical equipment and communication cables are also not specified, but subcategories or serial numbers are listed.

The seventh item is a mark for various special use occasions or additional special use requirements, and is marked with pinyin letters after the "-". Sometimes, to highlight this 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-termite, corporate standards) and so on.

Wire and cable distinguish <br> <br> fact, the "wire" and "cable" and no strict boundaries. Usually, the product with a small number of cores, a small product diameter, and a simple structure is called a wire. A wire without insulation is called a bare wire. Others are called cables. A conductor with a larger cross-sectional area (greater than 6 mm2) is called a large wire. Small (less than or equal to 6 mm2) is called a small wire, and an insulated wire is also called a cloth wire.

Naming principles and cases:

The complete naming of wires and cables is usually complicated, so people sometimes use a simple name (usually a category name) in combination with the model specification instead of the full name, such as "low voltage cable" representing all plastic insulated power of 0.6/1kV class cable. The spectrum of wires and cables is relatively complete. It can be said that as long as the standard model specifications of wire and cable are written, specific products can be specified, but what is its full name?

The following principles apply to the naming of wire and cable products:

1. Contents included in the product name (1) Product application or size class name (2) Product structure material or type;

(3) Significant or additional features of the product are basically named in the above order, sometimes to emphasize important or additional features, to write features to the front or to the corresponding structure description.

2, the order of description <br> <br> product structure as described from the inside out according to the principle: the conductor -> Insulation -> inner sheath -> outer sheath -> armored type.

3, simplify <br> <br> not cause confusion in the case of some structures described province or write shorthand, such as car line, soft line does not allow aluminum conductors, it does not describe the conductor material.

Case:

Rated voltage 8.7/15kV flame-retardant copper core XLPE insulated steel tape armored PVC sheathed power cable "rated voltage 8.7/15kV" - use occasion / voltage rating "flame retardant" - emphasized characteristics "copper Core" - Conductor Material "Crosslinked Polyethylene Insulation" - Insulating Material "Steel Tape Armored" - Armored Layer Material and Type (Double Steel Band Gaps)

"PVC sheath" - inner and outer sheath material (the same inside and outside sheath material, save the inner sheath material)

"Power cable" - the product's major class name corresponds to the model number written as ZR-YJV22-8.7/15, and the wording of the model will be described later.
