Product Feature:

Toroidal Transformer
This kind of toroidal transformers are available with ratings to 5000 VA, 50/60 Hz. Suited for applications such as inverters/converters, UPS systems, fuel cells, power conditioners, and solar generators, transformers offer the following advantages when compared to laminated constructions: low electromagnetic radiation, increased voltage regulation, high efficiency, low off-load power consumption, and up to 90% less mechanical hum.

Basic Data
Capacity: 20VA-5000VA
Phase: Single
Input: AC Power with Voltages of Various Countries
Output: AC Current, Voltage, According to Customers Requirements
Frequency: 50-60Hz
Voltage Regulation: 12%-3%
Manufacture Standard: GB/T15290-94, GB/19212-2006, GB2828-2829-87
Insulation Class: B, 130 Celsius Degree; E, 120 Celsius Degree
Temperature-rise: ?85 Celsius Degree

Material
Core: High quality cold grain silicon sheets inserted by machine, annealed by advanced vacuum annealing furnaces to improve electronic data
Bobbin: Excellent Anti-combustion
Wire Materials:
1. Copper, Aluminum, Aluminum Clad Copper.
2. The size of transformer total in Aluminum is larger than which total in Copper.
3. Aluminum instead of Copper Cost Save: 13%-35%/PCg

Comparison on Transformer with Toroidal, EI, R, CD Shape Core
Since 1995, we have been playing a leading role to replace the types of R, CD, EI with toroidal type for our customers from each part of the world.
Core EI, R & CD Toroidal
Dimension Not Adjustable Adjustable
Performance Average Better
Reliability Average Better
Price Expensive 10%-30% Cost Saved

2) Altitude: Mounting location can not exceed the altitude of 2000m
3) Relative humidity: Maximum 90%
4) The site not attack by rain and snow
5) The medium which no explosion danger, no corroding metal, no electrical breakdown

Testing Items:
No-load Test(No-load Current, No-load Voltage, No-load Loss)
Load Test (Load Voltage, Temperature-rise)
Inductive Voltage Test
DC Resistance Test
Safety Test

Features of Encapsulation:
Well encapsulated by iron shell or plastic shell to adapt various outdoor hard working environment. Anti-shock, Anti-moisture, Anti-dust, High anti-strength

Installation
Horizontal (Non-conventional-type base plate), Sunk, Side Type, Bridge

Productivity:
Toroidal/annular/ring transformer 2 million PCS annually,
EI transformer 3 million PCS annually;
Three Phase Transformer 50 000pcs annually,
Others 100 000pcs annually .

Workforce:
About 200 workers, 5 technicians, 2 senior engineers

Equipment:
Over 50 sets toroidal/annular/ ring coil winding machines, 3 EI type transformer lines, 2 sets of vacuum annealing furnaces, A set of nitrogen and hydrogen production equipment.


Warning
Under no circumstances should both ends of the fixing bolt simultaneously contact the metal chassis or framework as this would create a potentially dangerous 'shorted-turn'.

Certificate
The certificate of our transformer has CE CQC RoHs UL

Note
The above-mentioned toroidal transformer is frequently-used, we can also manufacture the products by customer design. And the specification is for reference, if has the change further, please take the material object as the standard.
