UL 75KVA 100KVA 12000V to 240/120V Oil Immersed Distribution Transformer Single Phase Pad Mounted Transformer

Overview of UL 75KVA 100KVA 12000V to 240/120V Oil Immersed Distribution Transformer Single Phase Pad Mounted Transformer

UL 75KVA 100KVA 12000V to 240/120V Oil Immersed Distribution Transformer Single Phase Pad Mounted Transformer is an enclosed, ground-level electrical distribution transformer commonly used in underground (UG) power systems. It steps down primary high-voltage electricity (e.g., 15kV or 25kV) to a lower secondary voltage (e.g., 120/240V or 480V) for safe distribution to residential neighborhoods, commercial buildings, and industrial parks. Its robust, lockable steel enclosure makes it safe for public areas.

Features of UL 75KVA 100KVA 12000V to 240/120V Oil Immersed Distribution Transformer Single Phase Pad Mounted Transformer

Ground-Level Enclosure: A locked, tamper-resistant, weatherproof steel cabinet that protects the internal components and ensures public safety.

Underground Cable Connections: Designed for easy connection to underground primary (high-voltage) and secondary (low-voltage) cables via compartments with built-in bushings.

Compartmentalization: Separate, isolated compartments for high-voltage and low-voltage components, enhancing safety during maintenance.

Ventilation: Designed with louvers or other ventilation systems to allow for proper heat dissipation from the transformer core and coils.

Lifting Lugs: Integrated lifting lugs for easy and safe installation and replacement using a crane or hoist.

Tamper-proof Hardware: Lockable doors with special bolts to prevent unauthorized access.

Fused Switches: Often includes fused disconnect switches for circuit protection and safe isolation.

Pad Foundation: Installed on a concrete pad (“pad-mounted”) to provide a stable, level base.

Specifications of UL 75KVA 100KVA 12000V to 240/120V Oil Immersed Distribution Transformer Single Phase Pad Mounted Transformer

This UL-listed transformer steps down high voltage electricity for local power grids. It takes incoming 12,000 volts and converts it safely to standard 240/120 volts. This voltage is perfect for homes and small businesses nearby. The transformer handles either 75,000 VA (75 kVA) or 100,000 VA (100 kVA) of power. It is built for single-phase electrical systems.

The core and windings sit inside a sturdy steel tank. The tank is completely filled with special insulating oil. This oil keeps the transformer cool during operation. It also provides vital electrical insulation. The entire unit is sealed to prevent leaks. A pressure relief device protects the tank from internal pressure surges. This is a key safety feature.

You install this transformer outdoors. It sits securely on a concrete pad at ground level. This pad-mounted design keeps it accessible for maintenance. It keeps it safe from public contact too. The unit is self-contained. All high-voltage connections are inside locked compartments. This protects people and equipment. The low-voltage compartment is also secure and lockable.

The transformer meets strict safety and performance standards. UL certification confirms this. It undergoes rigorous tests for reliability. Expect dependable power delivery for many years. The steel tank features a durable finish. This finish resists rust and weather damage. Its weight requires proper handling equipment during installation. Sound levels are kept low during normal operation. The design focuses on safety and long service life.

Applications of UL 75KVA 100KVA 12000V to 240/120V Oil Immersed Distribution Transformer Single Phase Pad Mounted Transformer

This UL certified oil immersed distribution transformer steps down 12000 volts to usable 240/120 volts. It’s built for single phase power. The ratings are 75 kVA and 100 kVA. You see these transformers often mounted on concrete pads outdoors. They are very common. They bring medium voltage power safely down to levels homes and businesses need.

The main job is feeding power to houses. They connect directly to the utility’s medium voltage lines. Then they supply the lower voltage to residential areas. These transformers power entire neighborhoods. They handle the load from many homes. They are reliable for this everyday use.

Small businesses also use these transformers. Think shops, offices, or small industrial sites. They need reliable 120/240 volt power. This transformer delivers it. It powers lights, machines, and equipment efficiently. The oil inside keeps it cool. This cooling is vital for long life. It handles normal overloads without trouble.

The pad-mounted design is practical. It sits securely on a concrete slab. This keeps it off poles. It protects the unit from flooding and damage. Access for maintenance is straightforward. The enclosure is tough. It withstands weather and protects the internal parts. This transformer operates quietly. This is important near homes. The UL certification means it meets strict safety standards. This ensures safe operation near people and property.

5 FAQs of UL 75KVA 100KVA 12000V to 240/120V Oil Immersed Distribution Transformer Single Phase Pad Mounted Transformer

What does this transformer actually do?
It steps down high voltage electricity. It takes 12,000 volts from utility lines and changes it to 240/120 volts. This voltage is safe for homes and small businesses. It powers things like lights, outlets, and appliances.

What are the main specs?
This is a single-phase transformer. It comes in two sizes: 75 KVA and 100 KVA. The input voltage is always 12,000 volts. The output is always 240/120 volts. It uses oil for cooling and insulation. It sits on a concrete pad outside.

Why is it pad-mounted?
Pad-mounting means the transformer sits securely on a concrete slab at ground level. This makes it easy for utility workers to access it. It’s safer than overhead transformers. It protects the unit from weather and accidents. It’s common in neighborhoods and commercial areas.

What does UL certification mean?
UL certification shows the transformer meets strict safety standards. Independent experts tested it. It confirms the unit is built safely and reliably. Utilities often require UL certification. It gives users confidence in the product.
