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.
