Product Details

1. General introduction:

Transformer is made by high quality of material and advanced workmanship of technology.

This series of transformer not only have the ability to adjust the pressure, but also can isolate the three times of harmonic produced by power grid to equipment and protect to reduce the fever produced by machine and the lifetime of Insulation materials. They can be equipped and used directly on load of different natures and can be used in the work sites that Utility the voltage needs to be change or isolated safely.

These parameters or parts of transformer including input and output voltage (Single-phase, three-phase, more ways of input and output etc),the distribution of volume of Quad tap, outside case (equipped or not) can be designed and produced elaborately according to the requests of clients.

2. Features:

Function of voltage transformation(For example:Y/ Y or Y/triangleConnection) Have Anti-interference function with the filter(For example: Can remove the third harmonicwith heat resistance, moisture resistance, stability, Chemical compatibility, temperature resistance, environmental protection, radiation and toxic properties.

3.Connection:

Detailed description :

Description of the transformer material
1) core
Imported from Taiwan with high quality silicon steel sheet, the main material for the 0.35 thick H18, H14, H12, Z11's high-quality silicon steel, our guest rooms according to the requirements and conditions of use, choose the most suitable material, so that the transformer design to achieve the best performance.

(Conventional material for Taiwan's strong piece of steel H18 0.35 thick)

2) Wire
By PEW, UEW, EIW, SEIW, FEAI enameled wire, and glass envelope, the temperature rating for the F-level (155 °C), H-level (180 °C), HC-level (200 °C), C-level (220 °C). (Class B rating for general temperature 135 °C)

3) insulating material
DMS with high-quality environmentally friendly materials, with high temperature insulation, fire-retardant and moisture-resistant multiple properties; also available upon request NOMES selection of imported paper.

4) terminal blocks
Low-power terminal blocks used in Taiwan Mark, good looks, has excellent pressure, temperature, fire-retardant properties. High-power high-quality copper.

5) iron pin
Mainly CNC bending cold rolled plate, plated multicolored (yellow), blue zinc (silver), zinc white (ivory), surface anodized (black) and other environmental plating available.
