Medium-Voltage Cable Technician Certification

Medium-Voltage Cable Technician Certification


Finding the location of a cable fault doesn't have to be like finding a needle in a haystack. There are many locating methods, coupled with new detection technologies, that make this task much easier and less time consuming. However, you should understand that there is no single method or combination of methods that is "best." Your selection of the appropriate method for the situation and your skill in employing that method are the keys to safely and efficiently locating cable faults without damaging the cable. Splices and terminations, which are always a vital part of any cable system, become more susceptible to failure at higher voltages. Whether splicing or terminating is accomplished by the use of hand-applied tapes, a filled or molded device, heat-shrinkable tubing, or a prefabricated device, care should be exercised during the application. Poor workmanship or improper choice of materials could jeopardize the reliability of the entire system. This certification program will qualify technicians to safely splice, terminate, install and test medium-voltage cables. What is certification? Certification means you have achieved certain performance criteria - knowledge, skills and abilities through training. Certifications prove your skills, and their value is the recognition of customers, coworkers and employers. This certification also meets the requirements of OSHA 29 CFR 1910.269(a)(2)(vii).
