Hi,
In addition, you are right that it is an older designation. Now a days with the improvements 55/65 no longer really seems to have a role. 65 should do just fine.
Hi,
My understanding of 55/65 is that if you were going to put the TX in an enclosed area, such as a vault, you might request 55/65. Therefore, if it is placed in the vault your rated load would be the nameplate kVA. If you placed it outside per say, would could get a few more kVA out of it...
Thanks busbar,
Just to clarify the question I had though. I am referring to the Compaction Ratio when the connector is crimped over the conductor.
Compaction Ratio = ((Conductor Area + Connector Metal Area) /Die Size)-1
Should be between 5-20%...
If too small, the conductor won't be well...
Hi All,
When you are checking the compaction ratio of sleeves or lugs, which of the following do you use?
1) Always use the solid cable diameter dimension, as the conductor size
2) Use the type of cable you are using, as the conductor size.
For example if I have 750 kcmil compact cable. Do I...
rtrinblepe,
Tags are the current way of doing this. The problem is that, with time, they fall off and disappear. People have even pulled them off from inside the TXs, which are locked. It seems a good way, for the long term, is etching. While tags are okay, they far from great. Etching would...
I just wanted to thank you for the help. You've brought up some great points. Just for some clarity.
- You're right, the environment is very exposed to the elements. Dust and water will settle into the etched area.
- The lug is Al with Sn plating (etching done on the top of the lug).
- Lug...
First off thanks for the replies. As for more details.
We are considering etching civic addresses, onto the tops of tin plated aluminium lugs found in residental 120/240V transformers (outdoor transformers). The etching would be done on one lug, of the three which go from the transformer to...
Does anyone know of a study comparing tin plating of connectors such as hylugs to just straight aluminium? In addition would the etching on top of a tin plated connector (removing part of the tin plating) have any long term effects on that lug?
