TOPIC: CCV insulation surface cooling

CCV insulation surface cooling 2 years 9 months ago #497

Can any one suggest a soap liquid with less frothing to add in CCV line cooling water?

Hello,

We are assuming that you are adding a small amount of liquid soap to the cooling water of your CCV lines to prevent the phenomenon known as "Bamboo Cable". This is an environmentally responsible method of achieving the necessary lubrication in the cooling water.

Please make sure that you are not adding too much soap. Likewise, discussions with local soap wholesalers and manufacturers should quickly resolve this issue.

You can try adding lubricant to prevent the friction between the cooling tube and the cable.

Hello venkat,

I think you meant to write a lot more that you posted.

They are already using liquid soap dissolved in the water as the "environmentally green" lubricant.

"Bamboo Cable" is created by stiction (Sticky friction) at the touchdown point in the cooling section of the CCV tube.

Hello Peter,

Apology for the delay. The bamboo cable effect is mostly experienced with the cables manufactured with strippable outer semicon whereas for bonded outer semicon the effect is less. I feel, if it is due to sticky friction the bamboo cable effect should be the same.

Hello again venkat,

I agree with you entirely when it comes to bamboo cable and the strippable outer semi-conducting shield. If however it was a bonded shield, the stiction between the outer shield and the touchdown point is very low but not necessarily zero. Moreover polishing the inside of the tube at the touchdown point will only make matters worse as I am sure you know.

Since I am not on site and working with very limited information, I do not know what is going on, in terms of materials and process details.

I note that the person who started this thread and you are in the same city and country. Are you indeed the person who started this particular thread? It is very hard to understand your involvement without this information.
