This prevents unauthorized access. Tamper-proof construction is key. The enclosure resists weather and corrosion. It protects the internal components. These are ideal for utility use. They serve neighborhoods or commercial areas. Underground cables connect to them. Maintenance access is straightforward. Technicians can service them easily. Pad-mounted units offer reliability. They provide local voltage transformation. Their compact footprint is an advantage. They integrate well into landscapes. Security remains a top priority. These transformers deliver consistent power. They form a crucial grid link. Selecting the right size matters. Match the transformer to your load. Consider future expansion needs. Proper installation ensures long life. Regular maintenance checks are recommended. This guarantees continued safe operation. Quality materials make a difference. They ensure years of dependable service. These transformers power communities effectively.

Applications of Electrical Equipment and Supplies 11kV 125kVA 160Kva 500kVA Transformer 200kVA Pad-mounted transformers

These transformers step down 11kV power for everyday use. They supply safe, usable electricity to many places. Pad-mounted transformers sit securely on concrete pads. This design keeps them accessible yet protected. Their sturdy metal enclosure shields internal parts. This protection guards against weather, animals, and accidents. People find them in neighborhoods and business districts. They power streetlights, shops, and apartment blocks quietly. Their compact footprint saves valuable space. This is crucial in crowded urban areas or busy commercial sites.

Factories and workshops rely on these units too. They provide stable power for machinery and tools. Construction sites use them for temporary power needs. Their robust build handles tough outdoor conditions well. The 125kVA size suits smaller loads effectively. Think of a group of shops or a small office building. The 160kVA model offers a bit more capacity. It fits well for larger retail spaces or light industrial units.

The 200kVA transformer is a very common choice. It powers medium-sized facilities reliably. This includes schools, medical clinics, or larger offices. The 500kVA unit handles significant demands. It serves large commercial buildings, factories, or housing complexes. All these sizes maintain consistent voltage output. This keeps equipment running smoothly and prevents damage. Their low-noise operation is a major benefit. This matters in places where people live and work nearby. Safety is built into their design. The locked enclosure prevents unauthorized access. Tamper-proof features add extra security. Maintenance is straightforward for trained crews. Access points allow for easy checks and service. These transformers form a vital link in the power chain. They deliver electricity where it’s needed most.

5 FAQs of Electrical Equipment and Supplies 11kV 125kVA 160Kva 500kVA Transformer 200kVA Pad-mounted transformers

What size transformer do I need?
Check your total electrical load. Add up everything connected. Choose a transformer slightly larger than your peak demand. For example, a 200kVA pad-mount handles about 160kW continuous load safely. Oversizing by 10-20% is smart for future growth. Undersizing causes overheating and failure.

Where can I install a pad-mounted transformer?
These units sit outdoors directly on a concrete pad. You need clear space all around for ventilation and safety access. Keep it away from building walls, fences, or bushes. Follow local codes for exact distances from structures and property lines. The site must be level and well-drained.

How often must I service it?
Pad-mounted transformers need little routine maintenance. They are sealed units. Visually inspect the exterior monthly for leaks, damage, or vandalism. Check oil levels and test dielectric fluid yearly if accessible. Have a qualified technician perform thorough checks every 3-5 years. Listen for unusual humming or buzzing sounds anytime.

Is it safe near people?
Yes, when installed correctly. The steel enclosure protects people from live parts. It meets strict safety standards. Only trained personnel should open it. Always assume internal components are energized. Maintain the required clearances. Post warning signs clearly. Keep the public away from the unit.

What affects the price?
Size matters first. A 500kVA costs more than a 125kVA unit. Voltage rating and specific features add cost. Efficiency class (like DOE 2016) impacts price. Material costs (copper, steel, oil) fluctuate. Delivery distance and installation complexity add expenses. Get quotes based on your exact specs and location.
