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)
