RV Wire Extrusion Line

RV Wire Extrusion Line

RV wire is a general purpose single core flexible conductor unshielded cable. The conductor of RV wire is the fifth type of copper conductor (multiple strands of fine copper wire twisted together), and the insulation layer is made of PVC/C type polyvinyl chloride mixture. It is designed without a sheath, with a rated voltage of 450/750V and an upper limit of 70 ℃ for use. The letter "R" represents flexible wire, and "V" represents polyvinyl chloride (PVC) insulation.

RV wire has a wide range of applications in the industrial power distribution field, especially suitable for flexible installation sites with strict requirements, such as electrical control cabinets, distribution boxes, and various low-voltage electrical equipment. It can be used for the transmission of power, electrical control signals, and switch signals. RV wires and cables adopt a soft structure design, with a small bending radius of the conductor, and are suitable for installation in damp and oily environments.

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

Composition of Production Line

The RV 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.
