Preventing Capillary Action in Hot Chamber Wire Feed-throughs

Click For Summary
The discussion centers on the issue of oil leaking onto wires in a hot chamber during testing, caused by heat and capillary action. This contamination leads to difficulties such as slippery labels and handling challenges. Participants emphasize the need for improved sealing solutions to prevent oil from reaching the wires. Clarification is sought regarding whether the oil problem occurs inside or outside the chamber and the type of feed-throughs being used. Effective solutions are necessary to enhance the usability of the wires in this environment.

I have a strange problem. We test our components in oil in a hot chamber(60-100C). Wires are bought out of the chamber for power supply and data acquisition.
The oil from the chamber leaks on to the wires because of heat and capillary action.
This makes the wires oily and working with oily wire is a time consuming mess. Labels don't stick, they keep slipping etc even with gloves just to mention a few problems.

Capillary action does not bring a liquid to the top of the tube/hole it acts in.
You need a better seal.

The problem with oil on the wires is inside the chamber or outside? If outside, what type of feed-throughs are you using to get through the wall of the chamber?
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
