Dry Type Distribution Transformer
Henan New Electric Power Co.,Ltd. is a comprehensive enterprise integrating product research and development, product sales, and import and export services. It has more than 45 years of research and development experience. The company has a modern workshop of more than 120,000 square meters, a research and development center, and a staff apartment of more than 30,000 square meters. The production equipment is perfect, the testing method is perfect, the technical force is strong, and the qualification is complete. We can provide high, medium and Low Voltage Transformers with voltages of 110KV and below and capacities of 120,000 kVA and below for various purposes, as well as tap changers, gas relays, oil level gauges, moisture absorbers, valves, thermometers, insulators, fans and other accessories .
Dry type transformers are widely used in local lighting, high-rise buildings, airports, terminals, CNC mechanical equipment and other places. Simply speaking, dry type transformers refer to transformers whose core and windings are not immersed in insulating oil.

MCOB (Multipal chips on board, Multipal cups on board) is also called multi-cup multi-chip structure. It is a unique packaging process invented by Mr. He Wenming, the chairman of Wanbang Optoelectronics. The media has been reported many times on this process. Understand that the company has applied for more than 260 technical patents so far, and has provided comprehensive intellectual property protection for MCOB's packaging process and structure and appearance.
According to the company's technical director Tang Chunsheng, MCOB package structure is not only superior to the light-receiving performance of ceramic and aluminum substrates, but also boldly abandoned the aluminum substrate heat dissipation structure, using a single channel heat dissipation (ie, the chip is directly packaged in On the aluminum plate, the heat generated by the chip is very quickly dissipated. At the same time, Tang Chunsheng also introduced that after three years of technical improvement and industrialization practice, Wanbang has thoroughly identified various technical problems that affect the life and performance degradation of the light source. The yield has reached more than 99.96%. This quality has been verified in several large projects in China. Moreover, the company's products do not require any spectroscopic color separation, and the color consistency of batch installation is well controlled.
Based on the substantial improvement of the company's products, in order to quickly promote the domestic EPC (contract energy management business) process, under the leadership of Wanbang Chairman He Wenming, the company's technical indicators once again refreshed the record maintained by the company last year, reached Industry leading level, "LED industry can not develop, it is not price, but no good technology and good product support, which is also the biggest obstacle for EMC (contract energy management company) to develop, we develop high light efficiency, high The reliability of the product is to quickly promote the development of EMC," He Wenming said.
With the addition of EMC to better serve the domestic market, the company has decisively set up the operation center in the LED hinterland---Shenzhen. It is reported that the company's Shenzhen operation center has been set up and has begun to recruit a large number of excellent business personnel. 
Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). In case of natural air cooling, the transformer can operate continuously for a long time under rated capacity. In case of forced air cooling, the output capacity of transformer can be increased by 50%. It is applicable to intermittent overload operation or emergency overload operation; Due to the large increase of load loss and impedance voltage during overload, it is in a non economic operation state, so it should not be in a long-term continuous overload operation.
Wanbang Optoelectronics hits the LED industry hinterland
Recently, Wanbang Optoelectronics' mass production light source index has once again set a new industry record. It has reached 177LM/W through the inspection of Xiamen National Testing Center and Shanghai National Optical Power Testing. This technology uses Wanbang Optoelectronics' original MCOB packaging method.
