Product Description

Product Advantage

Product Features

The new standard came into effect on June 1, 2021, and new transformers must meet the new energy efficiency standard requirements, and the minimum requirement must meet the new level 3 energy efficiency class (S13 oil-immersed transformer).

1. S22 transformer oil has good insulation performance and good thermal conductivity, and transformer oil is cost-effective.

2. It can solve the problem of large-capacity heat dissipation and high voltage insulation of transformers.

3. S22 oil-immersed transformer is fully sealed, which effectively prevents insulation oxidation and is not easy to age.

4. S22 transformer core adopts higher material silicon steel sheet, increases the cross-sectional area of the core, higher energy saving, S22-630kVA than S13-630kVA annual power savings.

Product Uses

Here are five specific application scenarios of Transformers:

1. Commercial Complexes & High-Rise Residential

Modern commercial complexes and high-rise residential buildings require reliable, compact, and fire-safe power distribution equipment.

2. Industrial Parks & Heavy Manufacturing

Industrial parks and heavy manufacturing facilities, including steel mills, cement plants, chemical factories, and automotive assembly lines, consume large volumes of medium-voltage power and require robust, outdoor-rated distribution equipment.

3. PV & Energy Storage Grid Connection

Solar photovoltaic farms and battery energy storage systems (BESS) require dedicated step-up transformer solutions to interface with the medium-voltage grid.

4. Infrastructure — Rail Transit, Healthcare & Data Centers

Critical infrastructure applications, including metro and railway systems, hospitals, and data centers, demand the highest levels of power reliability and redundancy.

5. Municipal & Environmental — Water Treatment & Pumping Stations

Municipal water supply, wastewater treatment plants, and flood control pumping stations present challenging operating conditions for electrical distribution equipment. altitude not more than 1000m;
