Product Description

Overview

Combined transformer (also known as American box transformer) is a unified design of transformer body, high-voltage load switch, protective fuse and other equipment, installed in the same sealed oil tank, equipped with a complete operating inspection instrument pressure gauge, pressure release valve, Oil level gauges, oil temperature gauges, etc. American box substations have excellent performance such as reliable power supply, reasonable structure, rapid installation, flexibility, convenient operation, small size, and low cost. They can be used outdoors and indoors, and are widely used Various occasions such as municipal engineering, power grid upgrading and transformation, industrial parks, residential quarters, commercial centers and high-rise buildings.

Product features and functions

1. Fully sealed, fully insulated structure, no insulation distance, reliable protection of personal safety.

2. Small size, compact structure, only about 1/3 of the domestic box change with the same capacity.

3. It can be used for both ring network and terminal. The conversion is convenient and quick, which improves the flexibility of power supply and speeds up the power supply.

4. Energy saving, low loss, low noise, low temperature rise, strong overload capacity, etc.

5. The cable connector can operate 200A load current, and can be operated as a load switch in an emergency, and has the characteristics of an isolating switch, which is convenient and flexible to operate.

6. Double fuse protection is adopted, and the operation is safe and reliable.
