Product Name

Single-phase Transformer

Product Definition

A single-phase transformer is a stationary electrical device based on the principle of electromagnetic induction, exclusively used in single-phase AC circuits. Its core function is to step up, step down or isolate voltage. As a key piece of equipment for energy conversion in single-phase power supply systems, it is widely applied in low-voltage distribution, residential power supply, small-scale industrial equipment and other scenarios.

Core Structure

1. Iron Core: Manufactured with high-quality cold-rolled grain-oriented silicon steel sheets via laminated processing technology, which reduces hysteresis loss and eddy current loss and improves the efficiency of electromagnetic conversion.

2. Windings: Composed of high-voltage and low-voltage windings, wound with high-strength insulated wires. It features high insulation grade and excellent conductive performance.

3. Housing/Tank: Depending on the insulation and cooling mode, it is divided into oil-immersed tanks (for oil-immersed transformers) and dry-type protective housings (for dry-type transformers), providing dustproof, moisture-proof and mechanical shock protection functions.

4. Insulation System: Adopts high-temperature resistant and aging-resistant insulating materials to ensure the insulation performance and service life of the equipment under rated operating conditions.

5. Accessories: Including wiring terminals, temperature measuring devices, protection devices and other components to ensure the safe and stable operation of the equipment.

Core Advantages

1. Simple and compact structure, small size, light weight, convenient installation and transportation, with low comprehensive cost;

2. Suitable for single-phase power supply networks, with strong compatibility in residential, small commercial and other single-phase power consumption scenarios;

3. Optimized electromagnetic design with low no-load and load losses, high operating efficiency and remarkable energy-saving effect;

4. Flexible design, small size, suitable for installation environments with limited space, meeting diverse on-site installation requirements;

5. Mature manufacturing technology, low failure rate, good operational stability and simple and convenient daily maintenance.
