Flexible

TWISTABLE AND NON-TWISTABLE FLEXIBLE WAVEGUIDE The Mitec Telecom Ltd range of twistable (M1640) and nontwistable (M1650) flexible waveguide is available with a Neoprene or Silicone jacket in a variety of sizes from WR284 to WR28. The core is manufactured from pre-convoluted brass strip helically wound to extremely close tolerances around a rectangular mandrel. Twistable cores (M1640) are silver-clad and are locked by a plated copper sealing wire inserted into the seam during winding. Non-twistable cores (M1650) are also silver-clad and are locked by a solder wire, which forms a continuous solder fillet running the entire length of the seam. Non-twistable cores can be pressurised without a rubber jacket.
