Naming principle of wire and cable products

 

Naming principle of wire and cable products  

Wire and cable product name mainly includes the following contents:  

(1) Name of product application or size class  

(2) Product structure material or type  

(3) Important features or additional features of the product  

They are generally named in the above order, sometimes in order to emphasize important or additional features, features are written in front of the corresponding structure description.  

The general principle of product structure description is according to the principle from inside to outside: conductor -> insulation -> inner -> outer -> armored type.  

Power cable and communication cable naming method  

Power cable naming method  

The types and sequence of power cables are as follows:  

Type - conductor - Insulation - Jacket - Structural character-Jacket or derivate-Manganese tumover  

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

(1) Cable type  

ZR(flame retardant), NH(fire resistant), DDZ(low smoke low halogen), WDZ(low smoke no halogen), K(control cable class), DJ(electronic computer), N(agricultural directly buried), JK(aerial cable class), B(cloth wire), TH(humid hot area), FY-(termite, enterprise standard), etc.  

(2) Cable conductor  

T(copper conductor), L(aluminum conductor), G(steel core), R(copper flexible wire).  

(3) Cable insulation  

V(POLYvinyl chloride), YJ(crosslinked polyethylene), Y(polyethylene), X(natural styrene butadiene rubber mixture insulation), G(silicone rubber mixture insulation), YY(ethylene -- vinyl acetate rubber mixture insulation).  

(4) Cable sheath  

V(PVC sheath), Y(polyethylene sheath), F(neoprene mixture sheath).  

(5) Cable shielding  

P(copper mesh shielding), P1(copper wire winding), P2(copper belt shielding), P3(aluminum plastic composite belt shielding).  

Principle of omission in models: Copper is the main conductor material used in wire and cable products, so the code name of copper core T should not be written, except for bare wire and bare conductor products.  Bare wires and bare conductor products, power cables and electromagnetic cables are not listed in the category, and neither are wires and cables for electrical equipment and communication cables, but they are listed in the sub-category or series.  The seventh item is all kinds of special use occasions or additional special use requirements of the mark, in the "-" after the alphabetic alphabet mark.  Sometimes this item is written first to highlight the item.  Such as ZR-(flame retardant), NH-(fire resistance), WDZ-(low smoke halogen-free, enterprise standard).  

(6) Armored and outer sheath digital marking  

Zero: no  

1: interlocking armored fiber outer quilt  

2: double layer steel belt PVC coat  

3: fine round steel wire polyethylene coat  

4: thick round steel wire  

5: corrugated (rolled) steel belt  

6: double aluminum (or aluminum alloy) belt  

7: copper wire weaving  

Simplification In the case of not causing confusion, some structure description save or abbreviate, such as automobile wire, flexible wire is not allowed to use aluminum conductor, so do not describe conductor materials.  

Example: "ZR-YJV22-8.7/15" rated voltage 8.7/15kV flame retardant copper core xLPE insulated steel tape armored PVC sheathed power cable  

"Rated voltage 8.7/15KV" -- Service situation/voltage grade  

"Flame retardant" -- emphasized feature  

"Copper core" -- conductor material  

"Xlpe insulation" -- insulating material  

"Steel tape armoring" -- armoring layer material and type (double steel tape gap wrapping)  

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

"Power cable" -- product category name  

Communication cable naming method  

The naming sequence of communication cables is as follows:  

Classification code - insulation material code - jacket material code - derived characteristics - characteristic impedance - insulation core outside diameter integer value - shielding layer.  

(1) Classification code  

S stands for coaxial rf, SE for rf symmetric cable, AND ST for special RF cable.  Therefore, the classification number of coaxial cable is generally S;  

(2) Insulating medium materials  

Y stands for polyethylene, F for polytetrafluoron (F46), X for rubber, W for stable polyethylene, D for polyethylene air, U for fluoroplastic air;  

(3) Code name of sheath material  

V stands for polyvinyl chloride, Y for polyethylene, W for physical foam, D for tin copper, F for fluoroplastics;  

(4) Derived features  

Z stands for integrated/composite cable (multi-core), P stands for multi-core and a layer of shielding armor;  

(5) Characteristic impedance  

50 ohms, 100 ohms, 120 ohms;  

(6) Integer value of outer diameter of insulating medium core wire  

In millimeters 1, 2, 3, 4, 5......  

(7) shield  

General shielding layer has 1 layer, 2 layer, 3 layer and 4 layer.  

Example: SYV-75-2-1 Solid polyethylene insulated PVC jacket RF coaxial cable S: RF coaxial cable, class no  

Y: Polyethylene insulation, insulating medium material  

V: PVC outer sheath, outer sheath material  

75:75 ohm, characteristic impedance  

2:2 mm, integer value of outer diameter of insulating medium core wire  

1: single core (2 multi-core)
