180 Amp 6 Wire Slip Ring for Wind Turbine Generators

Write a Review


Keep your cable from twisting in the tower.

These 180 Amp 6 wire slip rings are small and compact with OD 30.00 mm x L 66 mm, standard, off-the-shelf. Color-coded lead wires are used on both the stator and rotor for simplified electrical connections, using a 90° V-groove ring design for each ring.

Not recommended for use with 48V wind turbines

These slip rings are ideal for our Freedom II PMGs and dual core PMAs.
