LD 220

Air choke with aluminium-copper/disc winding

LD 220

Unique Selling Point


  • No saturation
  • Wide range of material selection 
  • Special protective coating 
  • High linearity L (i) 
  • Very good mechanical strength 
  • No hysteresis 
  • Optimal weight by forced air cooling 
  • Directional air flow through GRP conduits
  • Very efficient liquid cooling option (waveguide) 
  • Able to be universally applied.

Description


Air chokes are particularly used where high inductive linearity is required. Due to their relatively simple mechanical structure, they are not only compact, but also very robust.

With our expertise, the REO air chokes perform to the required standard, even in the most arduous conditions.

  • Frequency of the current: DC und AC
  • Tolerances: + 10 / - 10 %, + 5 / - 5 %
  • Taps: By default, no taps (available on request)
  • Insulation: F or H
  • Cooling method and cooling liquid according to IEC 60310: AN, AF or WF
  • Test voltage: up to 12kV 60s 50Hz, up to 25kV 1,2/50µs
  • Mounting: Suspended, vertical or horizontal
  • Mechanical strength, mechanical simulation (FEM): EN 12663
  • Shock - and vibration stress: IEC 61373 Kat. 1 Kl. B

REO Mix & Match principle
