WTEC supplies overmolded cable assemblies for power and control applications in Solar and Wind plants. The overmolding makes the cable assemblies rugged to water penetration, mechanical abuse, and sunlight resistant.

The primary distribution mechanism would be via Medium Voltage Cables 15 kV – 35 kV. WTEC MV Cables are sized from 1/0 AWG through 1500 kcmil, 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 provides a variety of Grounding Conductors suitable for uninsulated hook up, jumpers and grounds in electrical construction. Bare copper conductors are primarily used in both aerial and buried applications; WTEC also offers an equivalent, copper clad steel, which can provide a significant cost savings. Along with these grounding cables, WTEC can supply various grounding terminations and connectors.


Power EquipmentWTEC also provides three phase padmounted distribution transformers that are designed and manufactured to meet all applicable ANSI and RUS standards for installation on three phase underground systems. Thesetransformers 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 panels, such as combiner boxes, to the renewable energy industry for over a decade. We are able to provide combiner boxes with multiple string configurations, listed to UL1741 standards, and enclosures that are NEMA 4X Fiberglass, and NEMA 3R, 4, 4X stainless steel.

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.
