Wafr Equipment
Under Development
Protection, control and distribution equipment for utility, industrial and data centre infrastructure.
Overview
Wafr supplies switchgear solutions for utility, industrial, commercial and critical infrastructure applications, with configurations selected around each project's power distribution, protection, control and monitoring requirements. Available solutions include indoor vacuum circuit breakers, metal-clad withdrawable switchgear and prefabricated distribution systems. Configurations can incorporate protection, interlocking, monitoring and control functionality based on project requirements.
Where required, equipment can be configured to meet applicable project and market standards. Specific standards, testing and certification requirements are confirmed for each deployment.
