hairpin extrusion from A to Z
Get to know the first industry-ready hairpin insulation line for the safe and efficient use of hairpins at 800V and above
1st turnkey hairpin extrusion line
RA-I, the first industry-ready turnkey hairpin extrusion line worldwide, is your all-in-one insulation solution for the safe and efficient use of hairpins at 800V and above.
Compared to conventional enamelling solutions, the extrusion process is significantly faster and more energy-efficient.
From pay-off to take-up, every line component of the RA-I extrusion line has been carefully synchronized to meet the high demands of the rectangular hairpin wire.
stable breakdown voltage
Extruded wires achieve stable breakdown voltage after thermal shock with just one layer of high-performance plastic.
firm adhesion
To attain their distinctive shape, hairpins need to be bent and twisted multiple times. The adhesion of the extruded insulation layer withstands these forces perfectly.
high temperature stability
chemical stability
superior electrical properties
mechanical stability
abrasion resistance
RA-I extrusion line for hairpin insulation
The compact RA-I insulation line is equipped with Rosendahl’s high-performance extruder technology and a specially developed crosshead for flat conductors. The complete conductor processing unit comes mounted on a base frame, well guided and stable, to maintain tight tolerances in production. From pay-off to take-up, every line component has been carefully synchronized to meet the high demands of the rectangular hairpin wire.
The processing of high-performance polymers requires a deep understanding of the underlying process, and equipment that meets the highest demands.
