Each CTL supervisor has over 20 years of experience in the manufacture and testing of power and control cables.

When using this service, the utility may select samples from each reel of cable for testing at CTL. Depending on the outcome of independent evaluations, the utility will accept or reject the cable. Results of tests at CTL are communicated promptly so as not to delay the shipment of cable.  Frequently utilized by most of our customers, this service has been essential to success on many occasions. When it comes to all of our services, you can count on us to take care of your every need. We pride ourselves on exceptional customer service and guarantee you’ll love working with our team.
