Wafr Equipment
Under Development
Pad-mounted, pole-mounted, dry-type, oil-immersed and 3D wound-core transformers for utility, industrial and data centre infrastructure.
Overview
Wafr supplies a broad range of distribution transformer solutions, including pad-mounted, pole-mounted, dry-type and oil-immersed transformers, with laminated, wound-core and amorphous-core configurations for commercial, industrial, utility and critical infrastructure applications. Transformer specifications can be configured to meet project-specific electrical, environmental, efficiency and installation requirements. Available configurations include copper or aluminum windings, radial or loop feed arrangements, live-front or dead-front connections, and a range of protection, monitoring and accessory options.
Where required, Wafr can supply transformer configurations designed to applicable project and market requirements, including IEEE, ANSI and IEC standards. Specific standards, testing and certification requirements are confirmed for each project.
