Description

Product Introduction

SG series three-phase dry-type transformers are widely used in various three-phase power supply places with AC 50-60Hz ,input and output voltages not exceeding 500V.

The input and output voltage of the product, the connection group, the number and position of adjustment taps (usually ±5%), the distribution of winding capacity, the equipment of the secondary single-phase winding, the use of the rectifier circuit, whether it is required to have a casing, can be designed and manufactured according to user requirements

Note:

The size is not indicated in the blank, and it is to be determined according to user requirements. The listed size is for reference. Products with output current greater than 300A are specially customized products, and the product size will change accordingly.

The rated input and output voltage in the table can be combined arbitrarily as required.

The voltage and size in the table can be negotiated and determined according to user requirements.

 

Product Features

  • Voltage Conversion and Stability: SG three-phase dry-type transformers can stably convert different input voltages (such as 575V, 480V, 440V, 415V, 220V, etc.) into 380V output voltage to meet the power needs of various equipment.
  • Efficient and energy-saving: With high conversion efficiency, such as some products achieving an efficiency of over 95%, it means that there is less energy loss during the voltage conversion process, which helps to reduce long-term usage costs.
  • Safe and reliable: adopting a dry-type design, without transformer oil, avoiding the risk of fire and explosion, while having good insulation performance and lightning impulse resistance, ensuring the stability and safety of equipment operation.
  • Strong adaptability: It has the characteristics of moisture resistance, shock resistance, salt spray resistance, etc., and can operate stably in various harsh environments, adapting to a wide range of load requirements.
  • Easy to maintain: small in size and light in weight, saving installation space, while the maintenance free design reduces maintenance costs and improves the overall economy of the equipment.
