ROHN 504 Porcelain Strain Insulator for up to 1/2EHS Strand Down Guy 12,000 lbs. Rating
The ROHN 504 is a Porcelain Strain Insulator rated at 12,000 lbs. Ultimate Strength with a 6,000 lbs. Working Load Limit (WLL) for up to 1/2" inch strand. It has 7/8" holes for Clevis and Preformed Dead-end Termination Down Guy Segments with a 4-1/4" length and a diameter of 3". Guy Line Insulators are used to isolate RF (Radio Frequency) Electrical Conductivity and Passive Re-Transmission or Intermodulation by dividing guy wires into non-resonant sections. This prevents the guy lines from altering an Antenna's Radiation Pattern due to near-field interaction and for Ghosting Resonate Towers to Prevent Shadow Zones of other Transmitter Facilities Broadcast Coverage Area. A compression-type design is used and the insulator is compressed within the wire loops, so that if the insulator should break, the guy wires are still attached. Breaking strength for these insulators is 12,000 pounds.
