I, BVV Basic introduction of wires:
BVV Cable Full name: copper core polychloride ethylene Insulated PVC sheathed round sheathed wire, also known as light PVC sheathed cable, commonly known as hard sheathed wire, is a kind of sheathed wire.
BVV Copper core polyethylene insulated sheath insulated cable, for home use Power Supply Plug , alias sheath wire ; Ring structure in case of single core, flat structure in case of multi-core ; Applicable AC current 450/750V And the following power systems, household appliances, instrument panels and communication products Wire and cable 。 It is also used to install cable wires. The long-term allowable operating temperature of the core shall not exceed sixty-five Degrees. As per specifications BVV The cross section of the wire is from 0.75-10 Square co ownership zero point seven five , one , one point five , two point five , four , six , ten There are seven specifications and models, which are commonly used. The ones that are too large or too small usually need to be customized by the manufacturer.
BVV The wires and cables are flame retardant, fire-resistant, low smoke and halogen-free, and can prevent two It is an environmental protection product that aims at the spread of secondary fire, uses environmental hazardous materials, and can relieve toxic gas and smoke in case of fire ; It is applicable to fire protection system, residential, commercial buildings and industrial power distribution circuits.
II, BVV And BVR What's the difference? ?
BVV Hard core structure wire, single core is round wire, double core is flat wire, with insulation layer and sheath layer, which is commonly used for surface installation.
BVR The flexible core structure wire is a single core wire, which is composed of multiple strands of conductors. It has an insulation layer but no sheath layer. It is often used for the connection of electrical appliances and the occasions with slight movement.
