Density of Electrical Cables/Conduits

Density of Electrical Cables/Conduits

Density of Electrical Cables/Conduits

(OP)


I'm looking for information on the weight/density of material for typical industrial heavy duty electrical cable wire as I need to design a cable tray support system.

Anybody dealt with this before?

The cable ladder allows cables to be layed to a depth of 115mm and a width of 600mm so if I can find the density of the cable, I can work out a weight per meter based on the cross sectional area of the cable ladder

RE: Density of Electrical Cables/Conduits

Perhaps find out what the cable trays themselves are rated to, then design the support structure based on that.

RE: Density of Electrical Cables/Conduits

I can't help with industrial cables. Here is a link with information for trays with data cables http://www.hoffmanonline.com/stream_document.aspx?.... Have you tried asking the electrical engineer?. The electrical code usually specifies a maximum percentage fill. If the EE tells you the type of cable, the weight and diameter can often be found on cable manufactures web sites. If you want a ball park number for preliminary design, pretend the tray is full of water (±62 lbs/ft3).

RE: Density of Electrical Cables/Conduits

dbest69er:

In the US the tray's maximum capacity (lbs/ft) is listed as a Class number - eg 12A. The document to consult is NEMA VE-1.

Regards,

DB

RE: Density of Electrical Cables/Conduits

We had weights from our electrical department for various widths and depths of cable trays. We used these for design.

I have been retired for over a year and no longer have access to this data.
