Cables, as crucial devices for transmitting electrical energy or data, play an indispensable role in power distribution and communication systems in buildings, factories, computer rooms, and other locations. Due to their wide range of applications, cables come in a wide variety of types, resulting in a diverse range of cable models. Below, we'll introduce several common cable models, including YJV, YJV22, YJLV, and KVV, and explain their meanings.
1. BV Cable
Recognized as single-core hard wire, BV Cable is renowned for its copper core and PVC-insulated wire. It plays a vital role in wiring within a home, for example, providing power to household appliances like televisions and stereos.
2. RVV Cable
It is a flexible, easily bendable, multi-strand twisted cable composed of multiple insulated conductors carefully twisted together. It is commonly used for low-voltage power transmission and control circuit construction.
3. NH-YJV Cable
Also known as flame-retardant and fire-resistant cable, it is designed specifically for fire protection systems and critical locations such as subways, shopping malls, and convention centers. Its fire-resistant properties make it an excellent choice for these environments.
4. YJV Cable
Featuring a copper core, cross-linked polyethylene insulation, and a polyvinyl chloride (PVC) sheath, this low-voltage power cable features excellent electrical performance and is moisture-, abrasion-, and corrosion-resistant, making it ideal for fixed installations indoors and outdoors.
5. YJV22 Cable
This is a copper core, cross-linked polyethylene (XLPE) insulated, steel-tape armored, PVC-sheathed cable. Compared to YJV cable, this cable features the addition of a steel-tape armor, significantly improving its tensile strength and resistance to external forces. This cable is well-suited for underground or submarine installations.
6. RVS Cable
This is a copper core, PVC-insulated flexible cable similar to RV cable, but unique in that it is constructed from multiple strands of conductor, making it ideal for flexible wiring connections.
7. RV Cable
This copper core, PVC-insulated flexible cable is similar in appearance to RVV cable, but differs critically in its single-core design. This cable is commonly used for connecting circuit boards and low-power electronic devices.
8. YJLV Cable
Also known as aluminum-core, cross-linked polyethylene insulated, and PVC-sheathed cable, this is a type of low-voltage power cable. Compared to YJV cable, its aluminum core is lighter and more affordable. However, its conductivity and corrosion resistance are slightly inferior to those of YJV cable.
9. KVV Cable
This copper-core, PVC-insulated, and PVC-sheathed cable is essentially a flexible electrical wire. Its unique structure lies in its multi-strand insulated conductor, which makes it flexible and resistant to twisting and bending, making it ideal for use in mobile equipment and applications requiring flexible adjustment.
10. ZR-RV Cable
Known as a flame-retardant RV cable, it is specifically designed for fire resistance and exhibits excellent flame-retardant properties, making it ideal for fixed indoor installations.
In addition to the common cable types mentioned above, there are many other cable types, such as VVR, ZR-YJV, and NYY. In these types, the letter indicates the cable material and construction, while the number represents the rated voltage and number of cores. For example, the designation "YJLV-0.6/1KV 3x50mm²" indicates an aluminum-core, cross-linked polyethylene (XLPE) insulated cable. "0.6/1KV" indicates a rated voltage of 0.6/1 kilovolt, and "3x50mm²" indicates the cable contains three conductors, each with a cross-sectional area of 50 square millimeters.
When selecting a cable, it's crucial to choose the appropriate model based on the specific application and needs. Furthermore, when purchasing a cable, pay close attention to key information such as the manufacturer, quality grade, and certification standards to ensure the safety and reliability of the selected cable.
