Several principles for the designation of wire and cable

Complete named Model naming overview <br> <br> wire and cable is usually more complex, so people sometimes use a simple name (usually the name of a category) combined model specifications instead of the full name, such as "low voltage cable" represents 0.6 /1kV class all plastic insulated power cables. 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 category 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 structure of the description of the order Product structure description from the inside to the outside principle: conductor -> insulation -> inner sheath -> outer sheath -> armored type.
3, Simplified In the case of no confusion, some structures describe writing or abbreviations. For example, aluminum conductors are not allowed in automobile lines and cords, so conductor materials are not described.
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 category name corresponding to the corresponding model is written as ZR-YJV22-8.7/15, the model is written in the following instructions.
4. Use capitalization of the first letter of Hanyu Pinyin to indicate insulation type, conductor material, inner sheath material, and structural features. For example, Z stands for paper (zhi); L stands for aluminum (lv); Q stands for lead (qian); F stands for phase (fen); ZR stands for flame retardant (zuran); NH stands for naihuo.
5. Use numbers to indicate the outer sheath formation. There are two digits. No numbers represent unarmored layers and no outer layers. The first digit indicates armor, and the second digit indicates outer cover, as indicated by 41 for thick steel wire armored fibers.
6. The cable type according to the arrangement of the cable structure is generally in order of: insulation material; conductor material; inner sheath; outer sheath.
7. The cable product is represented by the type, rated voltage and specifications. The method is to add the description of the rated voltage, the number of cores and the nominal cross-sectional area after the model number.
Main Model List RV, RVV, RVVP, RVVY, RVVYP, KVVRP, (N)2YSLC, ZR-RE, ZR-REE, ZR-REEP, PUR, LIYY, LIYCY, LIYY(TP), LIYCY(TP), LI2YCY, PIMF, LIHH, LIHCH.
The characteristics of commonly used cables are as follows: CEF—EPN rubber insulated neoprene sheath, shipboard flame retardant power cable.
CVV - PVC insulated, PVC sheathed shipboard flame retardant power cable.
Oxygen tank wires often use BV, BX, RV, RVV series wires, including:
BV - copper core PVC insulated wire, long-term allowable temperature of 65 °C, the minimum temperature of -15 °C, the working voltage of AC 500V, DC 1000V, fixed laying in the indoor and outdoor, can also be deposited in the dark.
BX - copper core rubber insulated wire, the highest temperature of 65 °C, deposited in the room.
RV—PVC insulated single-core cord with maximum operating temperature of 65°C, minimum operating temperature of -15°C, working voltage of 250V AC, and 500V DC, used as internal wiring for instruments and equipment.
RVV - Copper core PVC insulated and sheathed flexible wire, allowing long-term working temperature of 105 °C, working voltage AC 500V, DC 1000V, used in wet, high mechanical protection requirements, often moving and bending occasions.
The common cable type VV is: PVC insulation (first V), PVC sheath (second V)
YJV22 said: PVC insulation (YJ), PVC sheath (V), steel belts (22)
The type plus “ZR†or “FR†is a flame-retardant cable (wire). Adding “L†to aluminum wire is simpler:
BVV--PVC insulated and sheathed copper wire,
BV--PVC insulated copper core wire,
BVR--PVC insulated copper heart cord,
BX--rubber insulated copper wire,
RHF - neoprene rubber sleeve copper cord.
