Product Introduction
Product name: DFW American cable branch box
Category: Cable branch box
Product introduction: Overview of American cable branch box: American cable branch box, with its excellent performance, standardized design, and beautiful appearance, is widely used in cable engineering equipment in cable distribution network systems. In major industrial parks, Residential quarters, densely populated urban areas, commercial centers, and high-rise buildings are generally recognized. It is characterized by one-way door opening and horizontal multi-pass busbars, and has the advantages of small width, flexible combination, full insulation, and full sealing. According to the rated current, it can be generally divided into 600A main circuit and 200A branch circuit. The 600A main circuit adopts screw-in bolt connection; the 200A branch circuit adopts plug-in connection and can be plugged and unplugged under load. American cable branch box model and its meaning: American cable branch box normal operating conditions: ◆Ambient temperature: temperature not higher than +40℃, temperature not lower than -30℃ ◆Wind speed: equivalent to 34m/s (not more than 700Pa)
Overview of American cable branch box
American cable junction box, with its excellent performance, standardized design, and beautiful appearance, is widely used in cable engineering equipment in cable distribution network systems. It is widely used in major industrial parks, residential areas, urban densely populated areas, and commercial Various places such as centers and high-rise buildings are generally recognized.
It is characterized by one-way door opening and horizontal multi-pass busbars, and has the advantages of small width, flexible combination, full insulation, and full sealing. According to the rated current, it can generally be divided into 600A main circuit and 200A branch circuit.
The 600A main circuit adopts screw-in bolt connection; the 200A branch circuit adopts plug-in connection and can be plugged and unplugged under load.
