Domino Highvoltage Supply is a privately owned leader in high-voltage solutions. Known for its specialization in supplying high-voltage materials and services, the company is an indispensable partner across various industry sectors. Its expertise shines in procuring material needed in the constructing and maintaining of overhead and underground distribution lines and substations, making it a distinguished entity committed to quality and safety.
A new testing division launched in 2017 added a new dimension to its services and expanded its business horizons.
Domino operates four state-of-the-art electrical test labs across North America and the Caribbean. These labs, known for their rigorous testing of rubber gloves, dielectric tools, and cover-ups, indicate the paramount importance placed on the safety of client companies in managing high-voltage equipment.
Building on this solid foundation, Domino showcases its dedication to industry standards and safety by adhering to ASTM standards and certification as a North American Independent Laboratories (NAIL) facility. This certification, already secured by two of its labs with a third set to be achieved by the summer of 2024, underscores Domino’s relentless pursuit of excellence. Its newest lab, opening in Houston, is poised to become fully operational soon, expanding Domino’s capacity and geographical reach.

Its innovative tracking and inventory management approach sets Domino apart in the competitive landscape. The company has pioneered custom tracking labels on rubber materials and tools, enabling detailed tracking of each item’s history, testing frequency, and results. This information is integrated into Domino’s proprietary global inventory management system (GIMS), offering unprecedented control over inventory and insightful reporting capabilities. The GIMS system streamlines internal processes and significantly benefits clients through customer portals. These portals allow clients to track their materials in real-time, providing updates on testing stages and shipment statuses.
Domino’s client-focused approach is further exemplified by its preemptive notification system. This system alerts clients about upcoming testing requirements, enabling efficient management of materials like gloves, sticks, and blankets based on their testing schedules. This foresight in material management is a hallmark of Domino’s commitment to client convenience and operational efficiency.
Whether supplying tools and materials testing promptly or sourcing alternate products that meet our client’s schedules, we solve problems and provide cost-effective solutions
Another distinctive service Domino offers is material storage. This service mainly benefits clients lacking the space to store materials awaiting testing. Domino’s storage solutions free up valuable client space and ensure that materials are stored in optimal, temperature-controlled conditions. This thoughtful storage and material management approach reflects Domino’s understanding of its clients’ diverse needs, especially in varying climatic conditions.
As Domino prepares to launch additional labs, it is on track to become one of the largest testing companies in North America. This expansion is a testament to its growth and reflects its commitment to servicing areas previously underserved by testing facilities.
“We have built our reputation as a leader in the industry by being responsive to our customers’ needs. Whether supplying tools and materials testing promptly or sourcing alternate products that meet our client’s schedules, we solve problems and provide cost-effective solutions,” says Scott Wallace, CCO of Domino Highvoltage Supply.
Central to Domino’s success is its quick response time and efficient service. The company maintains a turnaround time of 10 days or less for testing, significantly outperforming industry standards. This efficiency has been crucial in winning new clients, particularly those frustrated with longer lead times offered by other providers. Domino’s logistical flexibility, including scheduled drop-offs and pickups, further enhances client convenience and satisfaction.
Domino Highvoltage Supply is a leader in its field and a visionary company shaping the future of high-voltage solutions. With its eyes firmly set on growth and innovation, it is not just meeting the current needs of the industry but also anticipating and shaping its future directions.
