TFW series three-phase brushless excitation synchronous alternators by introducing and developing on foreign advanced technology of well-known alternators, are our newly developed products, The generator set by coupling the alternators with engine are mainly designed to serve as power generating unit in national defence, post and telecommunications, hospital, hotel, market and factory as electric appliances or standby power. The alternators are made as per standard JB/T3320.2-2000 and in conformity to IEC34-1. Being tested by national authority department, the generator's performance achieves advanced international level. The characteristic of alternators see as the followings:
1. Blushless, self-excited, insulation class H with high temperature 180º C, so can reliablly run in bad conditions.
2. Steel welding frame, casting end bracket, the alternators have two constrution of two-bearing and single-bearing;
3. Stator winding's pitch is 2/3, the output voltage wave is excellent;
4. Fine dynamic characteristics when load or unload suddenly;
5. Generally the alternators are two-bearing construction, also can produce for single-bearing construction;
6. TIF<50, THF<2%, the alternators with high quality of AVR have excellent properties;
7.12 leads are suit for different connections, generally the output voltages have: 400V/200V---50Hz and 480V/240V---60Hz;
8. The units can run at 50Hz and 60Hz;
9. The units can run at single phase by changing the output connections, but the power at single phase only is about 60% of three-phase's power;
10. Standard drip-proof type is IP21, if our customer requires that IP22 or IP23 are also produced; But the power will be reduced for 5% at IP23;
YHG series brushless three phase synchronous alternators are the newest products. YHG series generator's construction and shape are different from TFW2 series generaror, these are the most different between YHG and TFW2. YHG series alternators are designed to meet market's requirement.
The requirements for environment:
1. Altitude: Not exceed 1000m.
2. Cooling air temperature: 258~313K(-15 ~40º C).
3. Relative air humidity: Not exceed 90%.
Mindong Baiyun Electrical Machine Co., Ltd., is an export base enterprise of electric and mechanical products approved by National Economic and Trade Committee. It is one of 15 top electic motor and appliance enterprises in Mindong and a major taxpaying company in Fuan. It specializes in the production and export of series of electric generators, diesel oil power supply units and series of water pumps. Since its estalishment, sticking to the guideline of 'Seek development by science and technology, seek survival by quality, seek profit by management', the company has been developing rapidly by paying greet attention to product development and quality management. 100% of its products are exported to Southeast, Asia, Middle East, South America, Europe, The United States and othercounties and regions. Its electric motor for pumps passsed the national security certification of electric produxts in 1996. ST ans STC series of electric generators have passed departments and have been granted quality license of export participated in the Egypt International Fair and were granted the Pyramid Prize.
To strengthen the management and raise the corporate scale, the Company pays great attention to recruiting and introduction oftechnical talents. Introducing technical cadre-mem for within and ourside the province, the companu now has 4senior engineers, 8 engineers and 16 technical persons, which constitutes the Technical Development Department and enables the company to increasethe scientific and technolohical contecnts of its products and make contribution to the development of new products. There are workshops of generator, water pump and metalworking. 8 new production lines have examing equipment have been introduced to strengthen quality inspection and standardize production and management, move of working procedure and product export.
We are ready to meet coming guests from all sides with brand new looks, superior quality and service.
