Medium Voltage Cables & Accessories After power is converted into AC by the inverter and stepped up by the transformer, electricity is then distributed throughout the collection scheme. The primary distribution mechanism would be via Medium Voltage Cables (15kV-35kV). WTEC MV Cables are sized from 1/0AWG through 1500kcmil and are offered in assorted types of construction and configuration. All cables are suited for direct burial application and can also be manufactured for Cable Tray installation. Also installed with the Medium Voltage Cables are underground fiber optic cables, which provide data communication between the power generators. WTEC also supplies MV cable accessories, such as termination & splice kits, which connect the cables to power equipment. WTEC does more testing than industry standards require. IEEE 386 requires either Impulse or AC Withstand. We run both on all of our products.

WTEC Overhead Transmission Line Products
After all power is accumulated from the solar arrays, they are transmitted to the electrical substation, which steps up the voltage for connection to the main electrical grid. Overhead/Transmission Line cables are primarily utilized to distribute this power. ACSR cable offers optimal strength for transmission line design, and enables desired strength to be achieved without degradation of ampacity.
