LAN and Telephone wire insulation line

LAN & Telephone cable producers know very well the importance of process stability and repeatability.

With SAMP lines, set up is fast and rejects are minimal due to standardised and harmonised line components; in fact drawing, annealing and pre-heating are part of an avant-garde global system which 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
