Cables and wires on the market today come in a variety of specifications, types, and functions. So, what are the specifications and models of cables and wires? What do the abbreviations related to these specifications and models mean? As we all know, cable and wire specifications are represented by letters to easily identify different specifications and models. Therefore, to understand the names of some cables, we need to understand the meaning of the letters. Let's learn about the meaning and notation of cable and wire specifications and models.


Wire and Cable Specification Abbreviations


RVVP indicates a copper core, PVC insulated, shielded, PVC sheathed flexible cable with a voltage of 300V/300V, 2-24 cores.


RG indicates a physically foamed polyethylene insulated access network cable used to transmit data and analog signals in hybrid coaxial and fiber-optic networks.


UTP stands for local area network cable; KVVP stands for polyvinyl chloride sheathed braided shielded cable, a specialized cable used for SYWV(Y) and SYKV cable television and broadband networks; RVV stands for polyvinyl chloride insulated flexible wire; AVVR stands for polyvinyl chloride sheathed flexible cable; RV and RVP stand for polyvinyl chloride insulated cable; BV and BVR stand for polyvinyl chloride insulated wire; KVV stands for recommended readings.


Wire and Cable Specifications and Model Notation


Single-core branch cable specifications are expressed as follows: number of cables in a circuit * (1) * conductor and nominal cable cross-section, 0.6/1KV, e.g., 4 * (1*185) 1*95 0.6/1KV. Multi-core branch cables with the same sheath are expressed as: number of cable cores * nominal cross-section - T, e.g., 4 25 - t. Because branch cables include both trunk cables and branch cables, and because cables and wires have different specifications, models, and structures, there are two ways to express them: trunk cable FD-YJV - 4 * (1*185) 1*95 0.6/1KV and branch cable FD-YJV-4*(1*25) 1*16 0.6/1KV. Main and branch cables are marked together, such as FD-YJV-4 Wire and Cable Specifications*(1*185/25) 1*95/16 0.6/1KV.


Wire and Cable Applications


Various cable specifications and models include: power systems, information transmission systems, local telephone cables, television cables, electronic cables, optical cables, radio frequency cables, data cables, magnet wire, power communications, mechanical equipment, instrumentation systems, power cables, magnet wire, data cables, instrument cables, and many other fields. Cable and wire products fall into five categories: bare wire and conductor products, power cables, wire and cable for electrical equipment, communication cables and optical fibers, and magnet wire (winding wire).


After this introduction, I believe everyone has a certain understanding of the components of wires and cables and the specifications of various wires and cables. Due to the wide variety of wire and cable specifications, I will not introduce them one by one here. Finally, a reminder that when buying wires and cables, you must look for brands and buy from regular manufacturers to ensure safe use.
