Discussion Overview

The discussion revolves around the search for dielectric couplings, specifically in the context of their application in HVAC systems. Participants are sharing experiences and seeking information about businesses that sold these components in the past, as well as discussing specifications and examples of dielectric couplings used in high-voltage applications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant is looking to purchase dielectric couplings and is having difficulty finding suppliers, particularly those that operated in the mid-1990s.
  • Another participant inquires about the specifications of the dielectric couplings, including shaft diameter and torque, and suggests the possibility of using dielectric shafts that can withstand high voltages.
  • A participant mentions a specific application of dielectric couplings in an HVAC system, specifying a desired diameter of 3 inches.
  • A later post provides a historical example of a dielectric component, describing a 750,000-volt Cockroft Walton setup at Fermilab, although the source of the dielectric rod used is unknown.

Areas of Agreement / Disagreement

Participants have not reached a consensus on specific suppliers or the historical availability of dielectric couplings, and multiple inquiries and examples are presented without resolution.

Contextual Notes

Participants are discussing various specifications and applications of dielectric couplings, but there are limitations in the information provided regarding the exact requirements and historical context of the components sought.

Hello,

I am looking to purchase Dielectric couplings. I am located in the east coast (NY/NJ).

I am having trouble finding these, any help is appreciated.

Does anyone know any businesses who sold these during the mid 1990's ?

Dielectric universal shaft joint couplings? What shaft diameter and what torque? What about using dielectric shafts? I have seen one hold off about 750,000 volts.

thanks for your response

I hope this will help you i am looking for ones in this context "coupling was used in an HVAC
system" "3 inch"

The attached photo shows the 750,000-volt Cockroft Walton at Fermilab. The tower on the right is the Cockroft Walton. The tower at left is the high voltage shield with the ion source. At the base is a multi-horsepoawer motor. There is a vertical Lucite or Plexiglass rod, ~2" or 3" in diameter, that the motor runs to drive an alternator inside the high-voltage shield. Unfortunately, the rod is hidden from view. It was built ~1970. I do not know of anybody who remembers where it came from.
