Economical High Tension Jacket / Covers for Electrical Conductors

02/09/2013 9:28 AM

Hi All,

We are a maintenance consultancy and one of our power utility customers , has asked us to suggest ways to cover naked , live High tension conductors , 33kv, 11kv ...

Solutions from TYCO / Raychem can be used namely MVLC (medium voltage line cover), but i think thier high cost and inaccesbility prohibits thier use.

Do you know of companies in India, or anywhere else manufacturing HT covers, The product should be as easy as wraping a cloth ,IT may conform to bends , take various shapes and sizes. and be easy to wrap and unwrap. yet 33kv Insulating

regards

Sanjay

The only ethical response is "Thank you for your consideration however our consultancy has no prior experience at these voltage levels. Since an error will likely cause someone's death we suggest that you contact those companies known to have expertise in these matters."

What shows that you have no expertise at these voltage levels? The Tyco Electrical Test Report for their MVLC shows a rating of 15kV without mastic and 25kV with mastic. It should be apparent that this will not withstand 33kV available across line conductors, also you should note that the only way the withstand voltage is increased is through the use of a sealing mastic, this implies that the mere wrapping of an insulating cover "...to provide accessibility..." will probably not be safe at these voltage levels. Hire someone who has done this before.
