Product Quality is a given, as you CANNOT risk your company’s reputation on anything less. The expectation of reliability has never been greater, in spite of the fact that there is more breadth and complexity to the electrical system.

“Our modern electric power grid has been called the biggest and most complex machine in the world – delivering electricity over 200,000 miles of high tension transmission lines and touching almost every aspect of our lives.” (http://www.pbs.org/america-revealed/episode/3/ Terms of Use Privacy Policy Copyright © 2014 Lion Television.

Not only does your larger customer base cause you to support a very diverse range of specifications (you certainly want to provide your customers with the product that fits their specific needs), there are many instances where they delay spec’ing CTs until late in the design process, and in some cases they change their specification at the 11th hour- shutting down production and possibly leading to late penalties. You need to know that you can have the exact CTs your customer wants, when you need them.

In addition, you certainly don’t want to buy your CTs from one of your competitors who could put their priorities over your own.

These days, there is more competition than ever before, so you need to really focus on delivering value (and a lot of it). It seems like every year there is a new, well-funded competitor to go up against. What are you going to do?
