Specifications of 33KV 415V 500KVA Three Phase Pad Mounted Transformer

This transformer is a three-phase pad-mounted unit. It steps down voltage from 33,000 volts to 415 volts. Its rated capacity is 500 kilovolt-amperes. This unit suits outdoor installations on concrete pads. It powers commercial buildings or industrial sites reliably.

The primary voltage connects to the high-voltage grid at 33kV. The secondary voltage provides 415V for local distribution. This matches common low-voltage equipment needs. The transformer handles continuous 500kVA loads efficiently. It manages peak demands safely.

The transformer uses mineral oil for cooling and insulation. This oil circulates naturally. The tank is robust steel, welded for strength. It resists weather and corrosion well. The unit features external cooling fins. These fins increase surface area. They help dissipate heat effectively.

Primary bushings are on the high-voltage side. Secondary bushings are on the low-voltage side. These bushings are durable porcelain. They provide secure cable termination points. The transformer includes tap changers. These changers adjust the output voltage slightly. They compensate for varying input voltage levels. Adjustment is usually off-circuit.

The core uses high-grade grain-oriented silicon steel. This steel minimizes energy losses. Windings are copper or aluminum. They are designed for low impedance. Low impedance helps control voltage drop under load. The transformer meets IEC 60076 standards. It complies with relevant national safety rules.

Protective devices are included. A pressure relief valve vents excess internal pressure. An oil level gauge shows the insulating oil volume. A drain valve allows oil sampling or replacement. Lifting lugs are standard for safe handling. The unit is designed for low noise operation. This minimizes disturbance near buildings.

The transformer offers reliable service. It provides stable voltage transformation. Its pad-mounted design saves space. Installation is straightforward. Maintenance requirements are minimal. This transformer delivers power efficiently for years.

Applications of 33KV 415V 500KVA Three Phase Pad Mounted Transformer

This 33KV/415V 500KVA three phase pad mounted transformer delivers reliable power where you need it. It steps down high 33,000 volt electricity to a usable 415 volts. This makes it perfect for many demanding situations.

Factories and big industrial plants use it constantly. It powers heavy machinery, large motors, and entire production lines without interruption. Its robust pad-mounted design handles tough environments well. It sits securely outside on a concrete pad. This saves valuable indoor space in crowded facilities.

Shopping centers, hospitals, and office blocks also rely on it. These places need steady power for lights, elevators, air conditioning, and essential equipment. The transformer feeds power directly to the building’s main distribution panel. Its compact outdoor installation is a major advantage in busy areas.

Renewable energy projects find it essential too. It connects solar farms or wind turbines to the main grid. The transformer adjusts the voltage to match the grid’s requirements. Its pad-mounted style simplifies installation in open fields.

Water treatment plants and pumping stations depend on its steady performance. It ensures critical infrastructure keeps running smoothly. The transformer’s enclosed tank protects the internal parts from weather and accidental contact.

Remote locations benefit greatly. Mines, quarries, or new housing developments need power fast. This transformer provides a ready solution. Its self-contained design means quick setup on a simple pad. Minimal site preparation is needed. Maintenance is straightforward for technicians.

The tough steel tank shields the core and windings. It resists corrosion and physical damage. The transformer includes necessary bushings, taps, and protection devices. It meets strict safety and performance standards. It delivers 500 kilovolt-amperes consistently. This transformer is a workhorse for medium voltage distribution. It brings high voltage power down to the level everyday equipment uses.

5 FAQs of 33KV 415V 500KVA Three Phase Pad Mounted Transformer

Here are five common questions about the 33KV/415V 500KVA Three Phase Pad Mounted Transformer:

What does this transformer do?
It steps down high voltage electricity. It takes 33,000 volts (33KV) from the power lines. It converts this down to 415 volts (415V). This lower voltage is safe for factories, large buildings, or housing areas. Its capacity is 500 kilo-volt-amperes (500KVA). This handles significant power demand.

Where is it installed?
Pad-mounted means it sits on a concrete slab on the ground. You install it outdoors. It needs a sturdy, level concrete pad. This is simpler than pole-mounted transformers. No poles are needed. The pad keeps it secure and accessible.

Is it safe outdoors?
Yes, the transformer is inside a locked metal enclosure. This tough metal box protects the internal parts. It keeps people out. It protects against weather like rain or snow. Tampering is difficult. Only qualified personnel should open it.

What maintenance is required?
Regular checks are important. Trained technicians inspect the oil level and condition. They check connections for tightness. They look for leaks or damage. They clean the enclosure exterior. Oil testing might be needed periodically. Follow the manufacturer’s schedule strictly.

Who uses this specific model?
It’s for medium-power needs. Factories needing 415V three-phase power use it. Large commercial complexes use it. Housing developments needing a local substation use it. Any project requiring reliable 33KV to 415V conversion at the 500KVA level uses it.
