Power Autotransformer Single Phase Pad Mounted Transformer Step up Transformer LZZBJ

Overview of Power Autotransformer Single Phase Pad Mounted Transformer Step up Transformer LZZBJ

Power Autotransformer Single Phase Pad Mounted Transformer Step up Transformer LZZBJ 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.

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 Power Autotransformer Single Phase Pad Mounted Transformer Step up Transformer LZZBJ

The LZZBJ is a single-phase power autotransformer. It is designed for pad mounting. This transformer steps up voltage. It suits various power distribution needs.

Its primary voltage rating is 10kV. Its secondary voltage rating is 11kV. Other voltage combinations are available. The capacity typically ranges from 5kVA to 100kVA. The standard frequency is 50Hz or 60Hz. This depends on the regional grid requirements.

The transformer uses high-grade silicon steel laminations. This core material minimizes energy loss. Copper windings ensure efficient conductivity. The windings are carefully insulated. This prevents electrical shorts. The insulation system is robust. It handles high voltage stresses reliably.

A welded steel tank encloses the core and windings. This tank provides strong mechanical protection. It shields internal parts from weather and damage. The tank is filled with high-quality transformer oil. This oil acts as an insulator. It also cools the transformer during operation. The oil level is visible through a gauge. An oil temperature indicator is standard.

High-voltage bushings and low-voltage bushings are mounted on the tank. These bushings connect the transformer to power lines. They are made from durable porcelain or composite material. They provide secure, insulated terminals.

The transformer includes a pressure relief device. This device vents excess pressure safely. It prevents tank rupture. Lifting lugs are welded onto the tank. These lugs allow safe handling during installation and maintenance. A grounding pad ensures proper earthing.

Rigorous factory testing confirms performance. Tests include routine checks and special assessments. These tests measure insulation resistance. They check turns ratio accuracy. They verify impedance values. Dielectric withstand tests are performed. Temperature rise tests ensure safe operation under load.

This transformer meets relevant international standards. It complies with IEC standards. It also meets IEEE standards. These certifications guarantee quality and safety.

The LZZBJ is ideal for rural electrification projects. It works well in residential subdivisions. It serves commercial power applications. It provides reliable voltage step-up where needed. Its pad-mounted design simplifies installation. It saves space compared to pole-mounted units. Maintenance requirements are low.

Applications of Power Autotransformer Single Phase Pad Mounted Transformer Step up Transformer LZZBJ

The LZZBJ is a single-phase power autotransformer. It is pad-mounted. This transformer steps up voltage. It is built for outdoor use. You see it near power lines. It sits on a concrete pad. This design saves space. It protects the transformer parts. The autotransformer design is key. It uses one winding for input and output. This is different from two-winding transformers. It uses less copper and iron. This makes it cheaper. It also makes it smaller and lighter. Installation is easier. Maintenance costs are lower. Efficiency is often better too.

Its main job is boosting voltage. It takes lower voltage and makes it higher. This is vital for power distribution. Power travels long distances better at high voltage. Less power is lost on the line. The LZZBJ does this step-up job reliably. It handles medium voltage levels. Common inputs are like 7.2kV, 12kV, or 24kV. Outputs go higher, like 13.8kV, 25kV, or 34.5kV. Exact voltages depend on the model. It connects directly to overhead lines or underground cables.

You find LZZBJ transformers in many places. They are used in rural areas. Power needs boosting over long feeder lines. They serve remote villages or farms. They help in renewable energy projects. Solar farms or small wind sites need voltage step-up. They connect to the main grid. Industrial sites use them. Factories needing local voltage boosts benefit. They are common in utility substations. They act as distribution step-up points. They feed power to neighborhoods. Their pad-mount design is safe. People and animals cannot easily touch live parts. It withstands weather. Rain, snow, and wind are not problems. It handles temperature changes. The LZZBJ provides a simple solution. It boosts voltage efficiently outdoors. It saves money on materials and installation. It offers reliable operation for utilities and industries.
