90+50 Building Cable High Speed Cable Extrusion Machine
1. Application
A 90+50 Cable Extrusion Line refers to a cable manufacturing system
capable of producing cables with two different layers or sizes of
sheathing. The numbers 90 and 50 typically represent the diameters
or cross-sectional areas of the respective layers of the cable.
Here's an overview of how a 90+50 Cable Extrusion Line may
function:
Payoff Unit: The system begins with a payoff unit that unwinds the
conductor wire from a spool or reel and feeds it into the extrusion
line.
Preheating Zone: The conductor wire passes through a preheating
zone to ensure it reaches the appropriate temperature for the
extrusion process.
Extrusion: The cable extrusion line consists of multiple extruders
or co-extruders. In the case of a 90+50 configuration, there are
two extruders for the respective layers of the cable.
Extruder 1: This extruder is designed to extrude the first layer of
sheathing material with a diameter or cross-sectional area of 90.
The plastic material, such as PVC, PE, or PP, is melted and
compressed in the extruder barrel before being forced through a die
to form the desired shape and size of the first layer.
Extruder 2: This extruder is responsible for extruding the second
layer with a diameter or cross-sectional area of 50. The second
layer material is similarly melted, compressed, and forced through
a die.
Cooling System: After extrusion, the cable passes through a cooling
system to solidify the sheathing layers. This can involve water
baths, cooling troughs, or other cooling methods specific to the
cable extrusion line.
Haul-off Unit: A haul-off unit grips the cable and pulls it through
the extrusion line at a controlled speed, ensuring consistent
tension and diameter for both layers.
Marking and Printing: If necessary, the cable may pass through a
marking or printing system to apply identification marks, logos, or
other required information on the sheathing layers.
Accumulator Unit: In case of disruptions downstream, an accumulator
unit temporarily stores the cable while maintaining continuous
extrusion.
Take-up Unit: The finished cable is wound onto a spool or reel
using a take-up unit, which controls tension and speed to
facilitate proper winding.
Throughout the process, sensors and control systems monitor
parameters such as temperature, pressure, and diameter to ensure
quality control and make necessary adjustments.
The specific configuration and features of a 90+50 Cable Extrusion
Line can vary depending on the manufacturer, desired cable
specifications, and customer requirements.
