UL Certification 3 Phase Oil Immersed Transformer Pad Mounted Transformer Outdoor Loop Feed

Overview of UL Certification 3 Phase Oil Immersed Transformer Pad Mounted Transformer Outdoor Loop Feed

UL Certification 3 Phase Oil Immersed Transformer Pad Mounted Transformer Outdoor Loop Feed 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 Certification 3 Phase Oil Immersed Transformer Pad Mounted Transformer Outdoor Loop Feed

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 Certification 3 Phase Oil Immersed Transformer Pad Mounted Transformer Outdoor Loop Feed

This transformer provides trustworthy power circulation outdoors. It’s a UL licensed unit developed for three-phase networks. The core and coils rest inside a steel storage tank full of protecting mineral oil. This oil cools down the transformer successfully during procedure. The whole assembly mounts securely on a concrete pad at ground degree. Its small, tamper-resistant enclosure makes it ideal for outside locations like neighborhoods or business areas.

Electrical rankings cover usual distribution voltages. Main voltages usually range from 2400V to 34500V. Second voltages are typically 120/240V, 277/480V, or 347/600V. Standard kVA ratings begin at 75 kVA and increase to 5000 kVA. Greater capacities are readily available. The device includes a loophole feed design. This allows power feed from 2 instructions for enhanced network integrity. Lots break arm joints or separable protected adapters provide key cord accessibility. These parts are conveniently obtainable under the cover.

The tank is robust bonded steel construction. It holds up against normal environmental stress and anxieties. Rust defense is common. Alternatives consist of unique finishings for harsh problems. The transformer satisfies IEEE C57.12 criteria. It likewise meets UL 506 demands. Fundamental impulse level (BIL) scores are suitable for its voltage course. This makes certain security versus voltage rises. Reduced noise degrees are accomplished with core design and building. Electrostatic guards decrease voltage distortion. Requirement accessories include stress relief devices, fluid degree assesses, and drainpipe shutoffs. Thermostats keep track of oil temperature level. Pressure vacuum bleeder shutoffs preserve container stress. Raising lugs and jacking pads simplify setup and handling.

Applications of UL Certification 3 Phase Oil Immersed Transformer Pad Mounted Transformer Outdoor Loop Feed

UL accredited 3-phase oil immersed pad placed transformers are difficult, trustworthy devices constructed for requiring outdoor electrical distribution. They fulfill stringent UL security criteria. You obtain proven security and efficiency. These transformers are designed for ground-level setup inside protective metal rooms. The core and windings sit inside a container full of protecting oil. This oil is essential. It cools the transformer successfully throughout procedure. It likewise supplies vital electric insulation and defense for the internal components.

Their main job is stepping down tool voltage power from energy lines. They supply risk-free, functional reduced voltage power right where it’s needed. This makes them ideal for loop feed systems. In a loop feed arrangement, power can move in multiple directions. This design decreases downtime. If one area fails, power can typically be rerouted an additional method. Utilities rely heavily on these transformers for neighborhood networks. They are likewise crucial for big commercial complexes, industrial parks, schools, hospitals, and big apartment. They power entire facilities reliably.

The outdoor-rated enclosure is key. It shields the transformer from harsh climate. Rainfall, snow, wind, dust, and sunlight won’t influence its operation. The oil insulation manages high electric anxieties well. These systems are constructed for long life with minimal maintenance. Their portable pad-mounted style conserves room. You do not require a separate structure or safe. Installation is uncomplicated right on a concrete pad. The UL accreditation supplies comfort. It implies the transformer passed rigorous tests for safety and security and construction. You understand it fulfills recognized sector benchmarks.

5 FAQs of UL Certification 3 Phase Oil Immersed Transformer Pad Mounted Transformer Outdoor Loop Feed

What does UL certification mean for this transformer?
UL certification proves the transformer meets strict safety standards. Independent experts test it thoroughly. This certification means the transformer is safe for people and property. It stops fires and electric shocks effectively. Customers know it’s reliable.

Can this transformer handle bad weather?
Yes. It’s built for harsh outdoor conditions. The tank is sealed tight against rain, snow, and dust. The materials resist rust and corrosion. We build it tough to last years outside. It performs reliably in storms, heat, and cold.

What happens if the oil leaks?
Leaks are very unlikely. The tank is welded shut securely. Special seals prevent oil from escaping. If a leak somehow happened, the oil is specially treated. This oil is less flammable and safer for the environment than older types.

What is a loop feed system?
Loop feed lets power enter and exit the transformer. Power can flow in two directions. This design keeps electricity running if one side fails. It’s common in neighborhoods and businesses needing constant power. It reduces outages for everyone connected.

How much maintenance does it need?
These transformers need very little maintenance. The sealed tank protects the internal parts. The oil inside cools and insulates the windings for years. Check oil levels and connections occasionally. A professional should inspect it periodically for safety.
