The Hammond 75kVA Sentinel G general purpose distribution transformer is designed to efficiently supply power to appliance, lighting, heating, motorized machine, and power loads from electrical distribution systems. Rated for 600 volts and below, this transformer features an aluminum wound construction and a 150C temperature rise, ensuring reliable performance. Its standard Type 3R enclosure makes it suitable for both indoor and outdoor applications, offering versatility and protection. With a standard 10kV BIL rating, it provides enhanced reliability and protection against critical equipment failure. The transformer utilizes a uniform 220C insulation system and is manufactured with quality non-aging, cold-rolled silicon steel laminations for improved performance and durability.This is a 75kVA, 3-phase distribution transformer with a primary voltage of 600 Delta and a secondary voltage of 480Y/277V. It features aluminum windings and a 150C temperature rise. The transformer is designed for general purpose use, rated for 600V and below, and is suitable for floor, wall, or ceiling mounting. It comes with a standard Type 3R enclosure for indoor/outdoor applications and a standard 10kV BIL rating. The insulation system is a uniform 220C with options for 80C, 115C, or 150C temperature rise. The core is constructed from precision-cut, non-aging, cold-rolled silicon steel laminations, coated to prevent moisture ingress. Conductors are precision wound with aluminum, electrically balanced to minimize axial forces during short-circuit conditions, and feature a robust interface between core and coils for improved short-circuit performance.
