Industry Overview in Power and Water Utility Sector
The power and water utility sector often faces critical challenges in maintaining electrical infrastructure in harsh underground environments. Flood-prone tunnels and manholes require durable and adaptable solutions that ensure operational reliability while minimizing maintenance costs and safety risks.
Key Engineering Challenges in Underground Utility Operations
A Californian utility company encountered significant obstacles in protecting electrical infrastructure within tunnels and manholes. In tunnels, maintaining reliable power and communication systems for lighting, ventilation, and safety equipment was crucial despite potential flooding and water ingress. Similarly, manholes required protection against water accumulation, debris buildup, and exposure to corrosive elements.
Advanced Engineering Solutions by SLAYSON® Submersible Junction Boxes
SLAYSON® Submersible Junction Boxes (JSMI Series and Aluminum Series) provided a tailored solution designed for the challenging underground environment. Meeting stringent NEMA 6P and IP68 standards, the enclosures guaranteed complete protection against prolonged submersion, dust ingress, and corrosion. The boxes were constructed from corrosion-resistant materials, including stainless steel (316), non-magnetic brass, and rugged marine-grade aluminum, offering versatile options based on environmental needs.
The customizable design included factory-installed cutouts and thru-holes for precise cable entry and conduit connections, ensuring watertight seals without field modifications. Custom welded-in-place hubs provided secure cable entry points, while internal mounting plates and brackets supported stable installation of electrical components. Stainless steel and brass hardware enhanced corrosion resistance, while the compact JSMI series fit efficiently into confined spaces like manholes.
