BV Wire Extrusion Line

BV Wire Extrusion Line

BV wire, also known as plastic copper wire, is a copper core PVC insulated distribution wire. B represents the category of electrical wiring, and V represents insulation made of polyvinyl chloride. It is suitable for cables and wires used in power plants, daily electrical appliances, instruments, and telecommunications equipment with AC voltage of 450/750V and below.

The BV wire extrusion line is a complete set of equipment specifically used for producing BV type copper core polyvinyl chloride insulated wires. Through extrusion technology, PVC insulation material is uniformly coated on the surface of copper conductors to manufacture building wires that comply with the national standard.

Composition of Production Line

The BV wire extrusion line mainly includes the following core equipment:
Pay off Stand: Release copper/aluminum conductors to maintain stable tension.
Preheating Unit: Heat the conductor to improve insulation adhesion.
Extruder: Melt PVC/XLPE and evenly coat the conductor.
Cooling Tank: Segmented cooling and shaping insulation layer.
Haul off: Control the speed of the production line.
Take-up Reel: Automatic winding of finished wires.
Testing Equipment: Spark tester, laser diameter measuring system, etc.

Process Flow

Pay-off → Preheating → Extrusion coating → Cooling and shaping → Spark detection → Printing → Take-up.
