Everyone has probably heard of BLV wire during renovations. So what is BLV wire? BLV is an aluminum core wire with an aluminum conductor and an aluminum core. It's a single-core, rigid conductor wire without a sheath. Below, we'll explain what BLV wire is.
What is BLV wire?
BLV stands for aluminum core PVC insulated wire.
The B series is classified as cloth wire, so it starts with "B." Voltage: 300/500V.
V stands for PVC, or polyvinyl chloride, or plastic.
L is the code for the aluminum core.
R stands for "soft." To achieve softness, the number of conductors is increased.
BV copper core PVC insulated wire.
BLV aluminum core PVC insulated wire.
BVR copper core PVC insulated flexible wire.
The above wire structure: conductor + insulation.
What is the difference between BLV, BV, and BVR?
RV copper core PVC insulated flexible connecting wire.
It's softer than the BVR cable, and the 2.5mm cable consists of 49 0.25mm copper wires.
RVV copper-core PVC-insulated, PVC-sheathed flexible cable
Has an additional plastic sheath compared to the RV cable.
Also, the most commonly used "sheathed cable," the BVVB copper-core PVC-insulated, PVC-sheathed flat cable, consists of two BV wires covered by a white sheath.
Take 2.5mm² as an example:
BV has one 1.78mm diameter wire and seven 0.68mm diameter wires, while BLV has one 1.78mm diameter wire and BVR has 19 0.41mm diameter wires.
This is an introduction to BLV cable from two perspectives. I believe you've already gained some understanding of BLV cable. BLV aluminum-core cable offers excellent electrical insulation, oil resistance, acid and alkali resistance, moisture and mildew resistance, and flame retardancy. It's reliable, easy to install, and durable. It's suitable for everyday household appliances and lighting applications.
