The dry winter is the peak of fires, many of which are caused by insulated power cable. As we all know, the current exceeding a certain voltage can cause great damage to the human body. Therefore, except for the copper conductor power cable erected at high altitude, corresponding measures need to be taken to prevent other kinds from being exposed. In fact, the exposed ac aluminum power cable not only poses a threat to the power supply system, but also damages the safety of people and property.
After development of more than one century, automatic die casting machine has become one of the important equipment in the foundry industry. Compared with other liquid forming methods, die casting machine for aluminum is widely favored for its advantages of high dimensional accuracy of castings, high productivity, and diversified molds. Among its many classifications, hot chamber and cold chamber die casting machines are the most common.
Power cables have been in use for many years. Since the emergence of copper core pvc cable, they have been favored by many in the power distribution system cable market due to their easy installation, operation and maintenance. In recent years, insulated pvc cable has been widely used in power transmission systems. Since electrical pvc cable is the basic guarantee for the safe operation of regional power grids, how to extend its life has become a hot topic in the industry.
