Client: Major West Coast Electrical Utility Company
Project Overview
A large utility company on the West Coast approached NJ Sullivan to design and manufacture custom Current Transformer (CT) cabinets with a unique bus bar layout and landing areas to accommodate multiple conduits and cables on-site. The project required a solution that could withstand external environmental exposure, deliver high current capacity, and meet an exceptionally short lead time.
Challenge
The client’s application required custom-designed 3,000A CT cabinets with interleaved bus bars in a bottom-in, bottom-out configuration. The cabinets needed to be robust enough for outdoor installation, exposed to the elements, and aesthetically consistent with the company’s existing equipment. Additionally, the project had to be completed within an aggressive six-week timeframe, from design to delivery.
NJ Sullivan’s Approach
1. Custom Design for Complex Requirements
NJ Sullivan’s engineers designed a cabinet that integrated an interleaved 3,000A bus bar system with customized landing areas to accommodate multiple in-situ conduits and cables. The “bottom-in, bottom-out” design provided the necessary flexibility for the client’s specific installation setup.
2. Material Selection for Durability and Aesthetics
To ensure longevity and protection in an outdoor environment, the cabinets were constructed from stainless steel and powder-coated for additional corrosion resistance and aesthetics. This material choice provided a durable, visually appealing finish that aligned with the client’s quality and appearance standards.
3. Efficient Collaboration and Rapid Prototyping
NJ Sullivan’s team collaborated closely with the utility company to confirm design specifications, conduct approval processes, and implement rapid prototyping. The client’s design was quickly validated, enabling the project to move forward without delays.
4. Assembly, Testing, and Fast-Track Shipping
Once approved, the cabinets were assembled, rigorously tested, and prepared for shipment within the six-week timeline. NJ Sullivan’s efficient project management and rapid production capabilities ensured that the custom CT cabinets met the utility company’s tight schedule.
Outcome
NJ Sullivan successfully delivered the custom CT cabinets within the six-week deadline, meeting the client’s specifications for high current capacity, environmental durability, and aesthetic quality. The utility company received a solution that was tailored to their unique installation requirements, enabling safe, efficient, and reliable operation.
