Low-voltage electrical appliances "fight" Which companies will "fire"?
Low-voltage electrical appliances "fight" Which companies will "fire"?
Polaris Smart Grid Online News: In recent years, China's low-voltage electrical appliance market has entered a high-growth era. Foreign capital, state-owned enterprises, and private enterprises have started to conquer cities and seize market share. The first-tier cities across the country have been slowly developing under the shadow of saturation of demand and policy pressures. If you want to successfully occupy a place in their own development in this extremely competitive environment, they will definitely not do without certain strength and correct market strategies. In the "big battle" in the low-voltage electrical market, which companies are already ready to move and are ready to start to seize the market?

The first step is to prepare the silver extraction solution (acid). The silver withdrawal liquid specifically dissolves the silver dots. The brass matrix and the copper matrix are not damaged, and the copper is sold directly after cleaning.
The silver contacts used in our switches can be judged as good or bad. The closing of the switch is achieved by the opening and closing of the silver contacts on the copper sheet to achieve the energized state. The thickness of the silver contacts directly affects the electrical conductivity. The thickness of silver coating of ordinary switches is 0.2-0.3mm, and the higher the thickness of silver coating, it can effectively reduce the generation of sparks during switch closing and prolong the service life of the switch.
Silver contacts have high electrical and thermal conductivity, low and stable touch resistance, good welding and processing functions. Fine-grained silver contains a small amount of silver in the silver, which greatly refines the material arrangement grains. In the case of almost the same touch resistance, its mechanical strength and temperature resistance are higher than that of silver. Therefore, the solder resistance and arc burn resistance are better than silver.
