Three Phase 750kva 1000kva 2550kva Pad Mounted Transformer

Overview of Three Phase 750kva 1000kva 2550kva Pad Mounted Transformer

Three Phase 750kva 1000kva 2550kva 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 Three Phase 750kva 1000kva 2550kva 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.

The 750kVA unit is a common choice. It handles primary voltages like 12470GrdY/7200V or 13200GrdY/7620V. Secondary voltage is typically 480Y/277V. Its sound level is low. It operates quietly in neighborhoods. The tank is compact. It fits well in confined spaces. This model is reliable for smaller commercial loads.

The 1000kVA transformer offers more capacity. It shares the same primary voltage options as the 750kVA. Its secondary output is also 480Y/277V. The construction is robust. It handles increased demand smoothly. Slightly larger radiators provide extra cooling. It suits larger buildings or small industrial sites. Its footprint remains manageable.

The 2550kVA unit is for major power requirements. It manages higher primary voltages. Options include 24940GrdY/14400V or 34500GrdY/19920V. Secondary voltage is commonly 480Y/277V. This transformer is physically larger. It needs more space on the pad. Heavy-duty radiators ensure proper cooling. Internal components are reinforced. They withstand significant electrical stress. This model powers large facilities, factories, or substations. Its design prioritizes durability under constant load.

All transformers use high-grade mineral oil. This oil insulates and cools effectively. Bushings are durable porcelain or polymer. They connect safely to overhead or underground lines. Pressure relief devices are standard. They protect the tank internally. External ground pads are provided. Proper grounding is essential. The units resist corrosion. The steel is galvanized or painted. They perform reliably for years. Installation is straightforward. Maintenance needs are minimal. These transformers deliver dependable power distribution. They are a solid investment for utility and industrial use.

Applications of Three Phase 750kva 1000kva 2550kva Pad Mounted Transformer

These pad-mounted transformers handle serious power needs. They step down high voltage electricity to safer levels for everyday use. The 750kVA size is common. You see it serving small neighborhoods or clusters of homes. It powers apartment complexes too. Small shopping centers use it. Light industrial parks find it suitable. It fits where demand is moderate but reliable.

The 1000kVA model steps up capacity. It powers larger commercial buildings well. Think big retail stores or office blocks. Schools and hospitals often need this size. It supports larger groups of homes effectively. Some medium-sized factories rely on it. It handles more equipment running together.

The 2550kVA transformer tackles heavy loads. Large industrial facilities depend on it. Major manufacturing plants use it. Big data centers require this power level. It feeds large commercial developments. Water treatment plants need this capacity. Mining operations frequently use it.

All these transformers sit above ground. This makes them easy to install and maintain. Workers access them safely without entering confined spaces. They are built tough. Their steel enclosures protect internal parts. They withstand harsh weather, rain, snow, and heat. Security features prevent unauthorized access. Tamper-proof locks are standard. They operate quietly. Noise is low near homes or offices. Their compact design saves space. They fit neatly into designated pads. This avoids the need for large substation buildings. They connect directly to underground power lines. This keeps areas looking tidy. Overhead lines are not needed. They are designed for long life. Routine checks keep them running smoothly. Utility crews perform maintenance quickly. Downtime is minimized.

5 FAQs of Three Phase 750kva 1000kva 2550kva Pad Mounted Transformer

Here are five common questions about 750kVA, 1000kVA, and 2550kVA three-phase pad-mounted transformers:

What is this transformer for?
This equipment steps down high voltage from power lines. It makes lower voltage usable for businesses and neighborhoods. Common sizes are 750kVA, 1000kVA, and 2550kVA. They handle significant power loads safely outdoors.

Is it safe around people?
Yes. The transformer is locked inside a sturdy steel cabinet. This cabinet is tamper-proof. People cannot easily touch live electrical parts. It meets strict safety standards for public areas.

What voltages does it handle?
Typically, the primary (input) voltage is 34.5kV or similar high voltage. The secondary (output) voltage is often 480Y/277V or 208Y/120V. This suits commercial buildings and large facilities. Confirm exact voltages for your specific project.

How is it installed?
The transformer arrives pre-assembled. Crews place it on a solid concrete pad at ground level. Underground cables connect it to the power grid and the building. Installation is generally simpler than pole-mounted types. The pad provides stability.

Where is this transformer used?
These units power large spaces needing reliable three-phase electricity. Examples include shopping centers, schools, factories, hospitals, and housing developments. The 2550kVA unit supports very heavy loads. The 750kVA and 1000kVA sizes are common for medium-large buildings.
