Wire insulation line for LAN and telephone cables

SAMP is a leader in the wire and cable manufacturing sector, known for providing innovative, high-quality wire insulation lines designed for the production of LAN and telephone cables.

SAMP lines’ set up is fast and rejects are minimal due to standardized and harmonized line components; in fact drawing, annealing and pre-heating are part of an cutting-edge global system that includes the extrusion group, ergonomic cooling troughs, and reliable dual spoolers. Moreover, customers also benefit from having a single supplier and a single team of engineers who can flexibly work on the whole line during commissioning and service.

Line types

• LI A1: to insulate copper conductors with solid PVC, PE and physical PE foam (skin/foam/skin) 
• LI B1: to insulate copper conductors with fluoropolymers (solid FEP or physical FEP foam)
• TI A1: to insulate copper conductors with solid PVC, PE and chemical PE foam (foam/skin)
• LI A1 - LI B1
- Foam/Skin and Skin/Foam/Skin processes with physical foam process
- Special pre-heating up to 200° C (LI B1)
- Skin pass module for the production of data cable
- Extruder screw designed to reduce and keep melt pressure constant at the gas injection point
- Stable automated extrusion process with limited fluctuations in capacitance and diameter
- Nitrogen injection unit controlled by line supervisor
- Fixed-centre extrusion head, with fine-tuning device for optimum wire concentricity
- Dual or triple extrusion head with striping capability
• TI A1
- Foam/Skin process with chemical expansion

Key features and advantages

• High production quality thanks to in-line drawing
• Reduced set-up time with reduction of reject material
