I am very upset!!

My name is Paolo, I am a Brazilian panel builder. I assemble low voltage power distribution panels using enclosure systems from International manufacturers also known as “functional” panels… and I’m tired of it! I can only state that the expectations are not met…

International manufacturers (ABB, Schneider, WEG…) promote “functional” or “modular” systems (for beginners sold in the form of kit, just like Ikea furniture!). The other solution is to use standard metal-sheet enclosures that many panel builders manufacture themselves.

I first thought that the kit system allowed me to save time with the assembling… However, there are a lot of drawbacks that make me question the relevance of this kind of “kit” offer…

Marvin M. sent us a nice article this week, so we tought we should share it with you. If you too want to be published on the blog, just send us a mail :) we’d be glad to discuss about it with you.

But for now, enjoy this article!

“I am sure nobody would want to grope around energized equipment, rotating shafts, variable drives, and power tools in the dark or dim light. Illumination is vital for all industries. The risk is injury and death. For this reason, it is important to install proper lighting systems in all sections.

Experts suggest that 75% of the lighting should be primary while the remaining for emergency lighting systems accounts for 25%. The following highlights the standards, emergencies lighting, monitoring, and control as well as recommended locations.”

journal1Last day, we published an article about common electrically conducting materials used in electrical cables. Now discover the second part of it…

Other than the core electrically conducting material, cable construction consists of non-conducting materials for functionality and aesthetics.

Insulators separate conductors to prevent short-circuits, as well as offer safeguard individuals. For this reason, the material must be able to contain the current within the required region. The common materials used include paper, rubber, and elastomers. Their individual properties are highlighted below.
