220KV Power Transformers.jpg

1. Flexible design to meet the needs of different users

First-class product quality in ChinaThe first-class R & D team in the industry ensures that the performance indicators of products meet or exceed the national standards, introduces scientific management mode, and standardizes the operation of each process to ensure the excellent quality of each product.

Flexible design to meet the needs of different usersAccording to the actual needs of customers, the product structure can be de. signed flexibly, and all kinds of accessories can be selected according to users' requirements, to meet the personalized needs of different customers.

2. Safe, no partial discharge, high efficiency, and energy-saving

1) Seven-stage temperature control technology

2) Low loss: adopt a special design scheme, the no-load loss is 20% lower than the national standard, and the load loss is 5% lower than the national standard.

3) Low noise: the noise is 3-5 dB lower than the national standard

4) No partial discharge: factory test is less than 40pc

5) Anti-short circuit: pass the sudden short circuit test of the national transformer testing center.

Scope of application: widely used in large and medium-sized city power grids large thermal power plants, and industrial and mining enterprises.

3. DuPont Nomex Insulation System

1) World-recognized high-quality electrical insulating materialsChemical - there is no weak C-H bond, with good chemical stability.

2) Heat resistance: long-term stable operation at 220 ℃; Short-term operation at 350 ℃; At 250 ℃, it will not melt, flow or support combustion; No toxic or corrosive gas will be released

at 750 ℃.

3) Safety, and environmental protection - no toxic reaction to people and animals; the smoke concentration is low and no harmful gas is produced during burning.
