Yangzhou's photovoltaic industry has also developed rapidly. Jiangsu Shunda Electronic Materials Technology Co., Ltd. of Yangzhou Economic Development Zone was established in 2006 to produce polycrystalline silicon wafers with a purity of 8-9. Polycrystalline silicon wafers are the raw material of solar cells that are currently in short supply in the world, and are the targets of many solar cell manufacturers competing for competition. The total investment of Shunda Phase I is 1.25 billion. At present, the company is in the construction stage. It will start trial production in July this year. The first phase will produce 1,500 tons of polycrystalline silicon wafers. In March next year, the second phase of 1,500 tons will be put into production. By then, it will reach an annual output of 3,000 tons of polycrystalline silicon wafers. Become a national photovoltaic industry production base.
Plug-in fuses are designed to be inserted into the fuse box. Fuse is small safety part in an electrical device or piece of machinery that causes it to stop working if the electric current is too high, and so prevents fires or other dangers. Fuse in the abnormal current increases to a certain height and heat, its own fuse to cut off the current, to protect the safe operation of the circuit fuse protection power equipment with current overheating damage, avoid electronic equipment serious damage caused by internal fault. When a circuit breaks down or is abnormal, the current increases with the current and the increased current may damage some important components in the circuit, and it may also burn the circuit and even cause a fire. If correctly placed in the circuit fuse, the fuse will be abnormal current increases to a certain height and heat, its own fuse to cut off the current, so as to protect the safe operation of the circuit.
