At present, most of the new energy rectangular terminals on the market are composed of insulating parts, conductive parts and fasteners, and the material, process, structure, and electroplating of the terminal block will affect the life of the terminal block!

Under the same quality, the worse the installation environment, the shorter the service life of the terminal block. Such as desert wind power generation and residential meter boxes, etc., the temperature and humidity of the environment are different, and the service life of the terminals is also affected.
Terminal blocks are also affected by voltage and current during use. For example, in the circuit, the terminals working in the state of high voltage, high current and high power are undoubtedly under pressure, and the damage is likely to be great.
In addition, some terminals are in transit, and violent handling will know that the quality of the terminals is damaged! And some terminals have been stored in the warehouse since production, and the performance and service life of the terminals will be shortened a lot over time!
