Relevant requirements for terminal blocks in terms of insulation

Since the terminal is mainly used to connect the electricity and connect with the electricity, the material and insulation performance requirements of the terminal are very high.
The first is the appearance: the terminal blocks with relatively good quality are the same as handicrafts. Although many companies understand this point, they do not pay attention to it. The terminal blocks must be convenient to use on the installation site. Because It is often necessary to install it on the front of the panel.
The second is the material selection of the terminal: the most important thing is that the insulation resistance should be high, so the insulator must use flame-retardant engineering plastics, and the conductive material should also be copper instead of iron. The terminal is on the plastic insulation. And conductive parts will directly affect the quality of the terminal, and will directly determine the insulation function and related conductive functions.
Therefore, when we choose terminal blocks, we must choose products with relatively good insulation performance, which can be selected according to the main purpose or different requirements of insulation.
