In outdoor large-scale power generation systems such as new energy photovoltaics and wind power generation, PE grounding terminals undertake the grounding connection function of key parts such as photovoltaic module brackets, wind turbine towers, and combiner box shells, and are an important link in ensuring lightning protection and leakage prevention safety of the power generation system. The grounding connection in such scenarios requires long-term exposure to the outdoors, withstanding exposure to sunlight, rain, temperature changes, and strong winds and vibrations. The requirements for the weather resistance and connection reliability of the terminals are much higher than those in ordinary industrial scenarios.

WD6-4mm Earth terminal block for new energy generally adopts a thickened copper bar conductive structure with a larger conductive cross-sectional area, which can withstand high current lightning impulse current without heating up, and the contact resistance is stable without increasing. The spring compression structure can automatically adapt to the deformation of the wire caused by outdoor temperature difference, avoiding connection loosening during long-term vibration and ensuring that the grounding path is always smooth. WD6-4mm Earth terminal block shell is made of modified engineering plastic that is resistant to ultraviolet rays and low temperatures. It can withstand temperatures as low as -40 ℃ without cracking, and long-term outdoor exposure will not cause aging or cracking. Its insulation performance remains stable.

This type of terminal also supports the connection of large cross-section grounding wires, suitable for multi strand grounding copper wires ranging from 10mm ² to 70mm ². Different specifications can be flexibly combined and installed. In photovoltaic combiner boxes, wind turbine control cabinets, and inverter cabinets, centralized grounding wiring is achieved, which is convenient for construction acceptance and regular testing. Compared with the traditional crimping copper bar connection method, the installation speed is faster, the cost is lower, and the grounding reliability is higher. It has become the standard choice for grounding design of new energy power generation systems.
