NIU Power introduces the Big Lead Assembly, or BLA for short. The BLA is an above ground aluminum trunk system that combines the functionality of cable assemblies, combiner boxes, and fusing all into one. This free air derated system eliminates the need for standard combiner boxes, messy multiple conductor string wires, cable trays, trenching, and field crimping. Factory manufactured and quality guaranteed.
H6 Galaxy Series integrated confluence products, using high-quality welding process to ensure the reliability of electrical connections. At the same time, the fire-retardant and weather-resistant adhesive sealing process is adopted to ensure the 30-year service life requirement of the product in the outdoor exposed environment. The products adopts a number of patented technologies, including but not limited to copper-aluminum transition composite process parts, wire welding process, cable fastening process and adhesive sealing process.
