10kva dry single phase step down trasformer 220v to 110v

                   10kva dry single phase step down trasformer 220v to 110v

HSLEC has been specizlied in Control Transformer for more than 20 years and it function to supply power to control and auxiliary equipment not connected directly to the main circuit. 

10kva dry single phase step down trasformer 220v to 110v is our one main products of control transformers.

Overview:

1. DG and SG series single - phase and three - phase dry type transformer adopts high quality material and advanced technology , it has advantages of damp - proof and convenient maintenance. 

2. It can be applied to such power transmission and distribution places like underground railway , high building, airport, station, wharf, enterprise, tunnel, etc.

3. It is mainly used in power supply occasions of AC 50~60Hz and voltage less than 1000V. All the input and output voltage , connection group and capacity of tapped winding can be designed and produced according to users’ requirements.  

Working conditions:

1. Ambient temperature: -25°C~+40°C 
2. Altitude: <1000m 
3. Relative humidity: <90% 
4. Environment exists without gas, steam, chemical deposition, dust or dirt that will affect transformer’s insulation seriously, also explosive or corrosive medium is not allowed. 
5. If any special working conditions that are not in line with the above stipulations, user shall negotiate with us.

 Photos of Control Transformers:

1. Fewer material used 

 As compared with three phase control transformers with the same capacity, single phase ones use less iron and copper materials. If single phase transformer is designed with a spiral type core, its no-load loss can be reduced by 15% or above. Thus, the production cost and use cost are greatly reduced, and the life cycle cost is maximized.

2. Low investment in transmission wire

 Single phase power supply system can save line by 33% to 63%. So, single phase dry type transformers are ideal for using in rural area and street light power supply systems.

3. Suitable for bulk production

Due to its simple structure, single phase control transformer is suitable for bulk production, which can help improve product quality and production efficiency.

4. Low construction investment

According to the statistics, shortening the distance of low voltage trunk line is an ideal way to reduce line loss. As the single phase control transformer is light weighted and convenient for installation, it can be simply installed onto telegraph poles to supply power. Thus, power supply quality is also improved.
