90+120+150 Extruder Insulation And Sheathing Line For Power Cable

1. Technical parameter:

2. Function of cable extrusion line:

Pay off unit: Pay off the wires to be extruded, two types pay off machine could be optional: active type or passive type.

Extruder: The heart of the line, where raw materials such as PVC, PE, XLPE, or other polymers are melted and mixed to form a homogeneous molten mass.

Crosshead or Die: The tooling that shapes and forms the molten material around the conductor or core wire to create the desired cable shape and thickness.

Cooling and Sizing Equipment: After extrusion, the cable passes through a cooling zone to solidify the insulation and maintain its shape. Sizing tools ensure the cable diameter remains within specified tolerances.

Take-up Unit: Pulls the extruded cable at a controlled speed, winding it onto reels or spools for further processing or packaging.

Control and Monitoring Systems: Includes sensors, gauges, and software that monitor and control parameters such as temperature, pressure, line speed, and diameter to ensure consistent quality.

Auxiliary Equipment: This includes devices for material handling, pre-heating, cooling, and other processes that support the extrusion operation.

3. Maintenance of cable extrusion production line:

Regular Cleaning: Clean the extruder regularly to prevent buildup of debris, dust, or melted material. Use appropriate cleaning tools and solvents recommended by the manufacturer.

Inspect Wear Parts: Check wear parts such as screws, barrels, nozzles, and dies for signs of wear and tear. Replace them if necessary to maintain quality and consistency in cable production.

Lubrication: Lubricate moving parts according to the manufacturer's recommendations. This prevents friction and reduces the risk of breakdowns.

Temperature Calibration: Regularly calibrate temperature settings to ensure accurate melting and extrusion of the cable material. This helps in maintaining product quality and consistency.

Check Electrical Components: Inspect electrical components such as heaters, sensors, and controls for any signs of damage or malfunction. Replace or repair as needed to prevent electrical issues.

Safety Checks: Ensure all safety features are functional, including emergency stop buttons, safety guards, and interlocks. Safety should always be a top priority in operating machinery.

Training: Train operators on proper usage and maintenance procedures. Well-trained personnel are essential for efficient operation and early detection of potential issues.

Record Keeping: Maintain a maintenance log to track all maintenance activities, including inspections, repairs, and replacements. This helps in identifying patterns and planning future maintenance schedules.

Consult Manufacturer Guidelines: Follow the manufacturer's maintenance guidelines and recommendations specific to your cable extruder model. They may provide detailed instructions for optimal performance and longevity.

Emergency Preparedness: Have contingency plans in place for unexpected breakdowns or emergencies. This may include having spare parts on hand or access to technical support from the manufacturer.

4. FAQ:
Dear customers, there are several models for the cable extrusion production line. In order to recommend the suitabe model, we'd like to learn some information:
1. Bare wire diameter
2. Soft wire or hard wire
3. Insulation/Sheath layer thickness
4. Whether with color strips?

Best regards
