PVC Insulated Building Wire Extrusion Line

PVC Insulated Building Wire Extrusion Line

The PVC insulated building wire extrusion line is the most basic and widely used wire production equipment in the wire and cable industry, mainly used to produce various PVC insulated wires and cables, such as common H05V-K, H07V-R, etc. It uses extrusion technology to uniformly coat PVC (polyvinyl chloride) material on the surface of copper or aluminum conductors, forming an insulation layer, and ultimately producing wire products that meet electrical performance and safety standards.

Composition of Production Line

The building 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.

PVC Insulated Building Wire Extrusion Line Application

The PVC insulated building wire extrusion line is the basic equipment for wire manufacturing, which can produce various wire types by adjusting molds and process parameters. It can be used in construction, industry, and home appliances, as follows:
Building Power Distribution
Home decoration: Single core hard wire (lighting, sockets), multi-core flexible wire (distribution box).
Commercial buildings: Flame retardant wires (public places), fire-resistant wires (fire circuits).
Industrial Equipment
Mechanical equipment power cord: Sheathed wire (resistant to bending).
Control circuit: Shielded cable (anti-interference).
Home Appliances and Consumer Electronics
Internal wiring: Thin flexible wire (TV, air conditioner).
Power cord: Such as European standard lightweight power cord.
