WTEC Products are top of the line

WTEC does more testing than industry standards require. IEEE 386 requires either Impulse or AC Withstand. We run both on most of our products.

WTEC provides electrical components directly to turbine manufacturers and to wind farms in all phases of development. From the top of the tower to the utility interconnect; our product-packaged approach streamlines purchasing and material management while offering both cost and administrative savings.

WTEC has extensive knowledge of cable, tower internals, collection systems, substations and transmission lines, which allows our customers to take advantage of our expertise from the proposal stage to project completion. By offering cost and delivery evaluation, cross-referencing, material management and many other services WTEC ensures the cost-effective, on-time fulfillment of our customers' needs.

WTEC will find a solution for your project needs, whether that means a complete wind farm or a single component.

WTEC Medium Voltage and Fiber Optic Cables and Accessories

WTEC does more testing than industry standards require. IEEE 386 requires either Impulse or AC Withstand. We run both on all of our products.

After power is converted into AC by the inverter and stepped 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 thru 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 Overhead/Transmission Line Cables

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.

Cable Installation

In order to compliment its affiliated companies, WTEC has formed AED to provide installation services for wind farm collection systems. AED utilizes a noninvasive trenching method that minimizes ground surface damage and provides a high speed, cost efficient solution to your trenching needs. The company's single pass installation method permits the laying of the URD cable, fiber, ground conductor and marking tape, followed by backfilling and compaction in one motion.

AED's fleet of Rivard trenchers are extremely versatile, operating in both loose rock and soil. The company has expanded its installation flee with Tesmec rocksaw trenchers that can cut through hard rock at up to 32,000 psi. AED's technicians and equipment operators are highly trained industry professionals, experienced in trenching and laying cables.
