Standard Features
- Progressively wound coils with adhesive resins on thermally upgraded insulating paper provide increased short-circuit and thermal strength.
- Sheet conductor in LV windings enables the electrical centers in the high and low to align themselves, minimizing the vertical component of short-circuit forces.
- Reinforced core-coil assembly provides greater short-circuit withstand capability.
- Prototype testing ensures the JUMBO design can meet industry short-circuit standards and provide reliable service.
- Self-venting and resealing cover eliminates the need for an auxiliary pressure-relief device and offers increased safety through higher tank withstand.
- ANSI support lugs (hanger brackets) are rod-welded to the tank wall for added strength.
- Anodized, aluminum-laser inscribed nameplate offers longer-term readability.
- Lifting lugs are positioned directly opposite the cover beam support lugs, reducing the chance of the tank going out of round when lifted.
- Cover-mounted, high-voltage, porcelain bushings with eyebolt terminals are mounted on flat embossments on the cover and have undercut gasket seats for improved sealing. The eyebolt connectors are cast bronze-plated with tin.
- Low-voltage porcelain bushings with clamp-type terminals provide ease in making secondary terminations.
- Arrester mounting pads are resistance-welded to the tank wall, completely and uniformly filling the surfaces where pad and tank wall join to provide greater strength.
- Durable, corrosion-resistant paint finish.
