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 system. 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 various types of construction and configuration. All cables are suitable 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 Power Equipment Supplies

WTEC also provides three phase pad mount distribution transformers that are designed and manufactured to meet all applicable ANSI and RUS standards for installation on three phase underground systems. These transformers step up the output voltages of the inverters to the required distribution voltage. Available ratings are 30 kVA – 3.0 MVA with high voltages 2.4 – 34.5 kV (150 kV BIL) and low voltages up to 600 V. WTEC is a UL508A panel facility (E317121) that has been providing components, such as combiner boxes, to the renewable energy industry for over a decade.

WTEC Overhead Transmission Line Products

After all power is collected 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 used to distribute this power. ACSR cable offers optimal strength for transmission line design, and enables desired strength to be achieved without degradation of ampacity.
