The primary voltage is 20,000 volts. The secondary voltage is typically 480Y/277V or 208Y/120V. Standard bushings are on the sides. These accept separable insulated high-voltage connectors. The enclosure is heavy-duty steel. It resists corrosion and tampering. Padlock provisions are standard. This keeps unauthorized people out. Internal components are well-protected. The core and coils use high-grade materials. This minimizes energy losses. Efficiency is a priority.

Cooling is natural convection (OA). No fans or pumps are needed. This makes it quiet and low-maintenance. The transformer manages temperature rise effectively. This extends its operational life. It includes pressure relief devices. These protect against internal faults. Fault current withstand ratings meet ANSI requirements. The transformer handles short circuits safely. Fluid options include standard mineral oil. Less-flammable fluids are available too. This depends on installation rules. Accessories like gauges and surge arresters are optional. They enhance monitoring and protection.

Installation and service are straightforward. The design prioritizes technician safety. Clearances inside the enclosure are adequate. Routine checks are easy. This transformer delivers dependable power. It’s suited for commercial buildings or small industrial sites. Its robust construction ensures long-term performance. Compliance with ANSI/IEEE standards is guaranteed.

Applications of 200kva 20kV ANSI/IEEE Standards Loop Feed Radial Feed Supply Pad Mounted Transformer

This 200kVA, 20kV pad-mounted transformer meets strict ANSI/IEEE standards. It’s built for underground power distribution. Utilities use it widely. It works reliably in loop feed and radial feed setups.

Loop feed systems need dependable transformers. This unit handles that job. It allows power to flow in a continuous ring. If one section fails, power reroutes around the fault. This design minimizes outages for customers. It keeps the lights on for more people. The transformer connects seamlessly into these critical loops.

Radial feed systems are simpler. Power flows from a single source out to customers. This transformer serves well in these lines too. It steps down the 20kV distribution voltage to usable levels for homes or businesses. It delivers stable power where needed. Its compact pad-mounted design saves space.

The transformer sits inside a tough steel box. This box is locked and tamper-proof. It protects people from high voltage inside. The enclosure resists corrosion and weather. It stands up to harsh outdoor conditions year after year. The unit installs on a concrete pad above ground. This makes access easy for maintenance crews.

Safety is a major focus. The design includes pressure relief devices. These prevent dangerous buildup if internal problems occur. The transformer uses mineral oil for cooling and insulation. The tank contains this oil securely. Leakage is minimized. This protects the environment and prevents fire hazards.

Maintenance is straightforward. Crews can check oil levels and connections quickly. Terminations for underground cables are accessible. They are designed for reliability. The transformer offers a long service life. It provides consistent, efficient power transformation. This unit is a solid choice for modern utility grids. It meets the demands of both loop and radial network configurations.

5 FAQs of 200kva 20kV ANSI/IEEE Standards Loop Feed Radial Feed Supply Pad Mounted Transformer

Here are 5 FAQs for a 200kVA 20kV ANSI/IEEE Pad Mounted Transformer:

What is this transformer for? This transformer steps down high voltage electricity. It takes 20kV power from utility lines. It lowers the voltage to usable levels for homes or businesses. It’s built for loop feed or radial feed systems. Loop feed means power can come from two directions for reliability. Radial feed means power comes from one direction only. It sits on a concrete pad outside.

Why choose ANSI/IEEE standards? ANSI/IEEE standards are strict rules. They ensure the transformer is safe and reliable. These rules cover design, testing, and performance. Using this transformer means it meets North American utility requirements. It guarantees compatibility with other grid equipment. You get proven safety and consistent operation.

How is it protected? The transformer lives inside a tough metal enclosure. This enclosure is locked. It shields the electrical parts from weather, animals, and people. The case is strong steel. It protects against damage and unauthorized access. Safety is a top priority. The design prevents accidental contact with live parts.

What about installation? The transformer needs a solid, level concrete pad. This pad must support its weight. Proper clearances are vital around the unit. Follow the utility’s specific spacing rules. Correct grounding is absolutely critical. It protects against electrical faults. Always hire qualified utility or electrical professionals for installation. They know the local codes and safety procedures.

What maintenance is needed? These transformers are designed for low maintenance. They are very reliable. Regular visual checks are important. Look for oil leaks, damage, or rust. Keep the area around the transformer clear. Ensure vents are not blocked. More detailed checks involve oil testing. Utilities usually handle this maintenance. They check the oil condition and electrical parts periodically.
