The meaning of cable types

What do the cables BV, BLV, VV, VLV and KVV mean? There are various types and specifications of cables. The following is an introduction to the meaning of cables: The meaning of BV, BLV and other symbols in wires and cables. These symbols are some models of wires. B series is classified as cloth wire, so it starts with B. Voltage: 300/500V. Wires are divided into electromagnetic wires and general insulated wires according to their uses. Insulated wires are also called cloth wires. Insulated wires (cloth wires) refer to wires covered with insulation, including various connecting wires and installation wires. V is PVC polyvinyl chloride, that is (plastic) L is the code for the aluminum core T is the code for the copper core (usually omitted and not written) R means (soft). To be soft, you need to increase the number of conductors BV copper Core PVC insulated wire BLV aluminum core PVC insulated wire BVR copper core PVC insulated flexible wire Above wire structure: conductor + insulation. ==1 Take 2.5mm2 as an example: BV is 1 piece with a diameter of 1.78mm and 7 pieces with a diameter of 0.68. BLV is 1 piece with a diameter of 1.78mm. BVR is 19 pieces with a diameter of 0.41mm. RV copper core PVC insulated connecting flexible wire is softer than BVR, or 2.5 is 49 pieces of 0.25mm copper wire RVV copper core PVC insulated PVC sheath connecting flexible wires have an extra layer of plastic sheath than RV In addition: our most commonly used "sheathed wire" BVVB copper core PVC insulated PVC Vinyl sheathed flat cable is two BV wires with a white sheath. ==2 (OMG') high voltage cable related product recommendations: https://www.omgevcable.com/ev-cables/ev-high-voltage- cables.html
