During the two-day exhibition, there were many highlights. Whether it was the size of the exhibitors, the influence of the brand, the selection of the products on display or the unique layout of the booths, many professionals who participated in other LED exhibitions at home and abroad were impressed.
With the goal of “Building the World's Most Exquisite LED Exhibitionâ€, the 2011 First High-tech LED Lighting Exhibition will be held on August 30th at the Century Hall on the first floor of the Shanghai International Convention Center in China.
Highlight 1: Domestic brand routes also pursue unique ideas
In recent years, domestic brands have not only worked hard on product R&D and design, but also began to innovate in concept. Enterprises have begun to realize that it is not only from the product, but also to create a brand-new concept for consumers. The so-called brand is a concept that puts the product into the ultimate concept.
The boutique exhibition specially invited representatives from leading companies in various fields of the domestic LED industry chain to exhibit local high-cost LED sapphire substrates, chips, light sources and lamps, which impressed many professional visitors.
Fujian Wanbang Optoelectronics Technology independently developed a new generation of LED tubes to achieve the full light 140LM ​​/ W ultra-high light efficiency, and stunning debut boutique exhibition
Product Overview
As a distribution transformer, single-phase transformer has great advantages. It can reduce the length of low-voltage distribution lines, reduce line losses, and improve the quality of power supply. The transformer is designed with high efficiency and energy saving coiled iron core structure, and is mounted on the column. It is small in size, small in infrastructure investment, and can reduce the low-voltage power supply radius by more than 60%. It is suitable for rural power grids, remote mountain areas, scattered villages, agricultural production, lighting and power consumption, and also for the energy-saving transformation of railway and urban power grids.
Structural characteristics
1. High voltage coil is wound with high-quality polyurethane enamelled round copper wire, and low-voltage coil is wound with cable paper wrapped wire. The interlayer insulation uses adhesive tape. During the coil drying process, it begins to melt at a certain temperature, producing adhesion. With the increase of temperature, it starts to solidify, so that adjacent layers of the winding can be reliably bonded into a fixed unit to prevent coil winding displacement, thus ensuring the safety and reliability of the insulation structure.
2. The iron core is made of silicon steel sheet or amorphous alloy silicon steel sheet rolled with grain orientation, which can ensure that the flow direction of magnetic flux is consistent with the grain orientation of silicon steel sheet, giving full play to the excellent performance of the material, and the no-load loss is far lower than the standard requirements, further effectively reducing the noise level of the transformer.
3. The oil tank adopts a fully sealed structure to enhance the reliability of operation, and normal operation is maintenance free.
