The Chuanli branch box is divided into 1kV low voltage and 10kV medium voltage two series, which must correspond to the same voltage level cable, strictly prohibiting the use of high and low voltage mixed.<\/span><\/p>\n<p><b>Matching of carrying capacity:<\/b><span style=\"font-weight: 400;\"> The rated current of busbars and terminal blocks in the box should be greater than the long-term working current of the cable, and a reserve of 10% to 20% should be reserved to prevent overload and heat generation. For large-diameter and high-current cables, branch boxes with large-size terminal connectors must be selected.<\/span><\/p>\n<p><b>Interface aperture matching:<\/b><span style=\"font-weight: 400;\"> The aperture of the branch box in and out of the line needs to match the outer diameter of the cable.
