What is the maximum current through the eight square copper wires
Cable bridge installation specifications inside: cable bridge multi-layer installation control cable between not less than 0.2M, power cable between not less than 0.3M, weak cable and power cable between not less than 0.5M, if the shield cover can be reduced to 0.3M, The upper part of the bridge is not less than 0.3M from the ceiling or other obstacles. Different voltage for different purposes of the cable should not be laid in the same layer of the bridge if the conditions are limited to laying in the same layer of the bridge, the middle need to add partitions. In order to prevent the human body from touching or excessively close to the charged body, or to prevent the vehicle and other objects from colliding with the charged body, and to avoid a variety of short circuits, fires and explosions, between the body and the charged body, between the charged body and the ground, Between the charged body, between the charged body and other objects and facilities, must maintain a certain distance.
---------------------- extended reading ------------ ------ Select the industrial communication cable, first meet the impedance (Z0 = 120Ω) match, and then according to the specific communication rate, transmission distance, wiring environment, laying mode configuration different model specifications
Yellow / green color line specifically for the protection of the ground! Other lines of color are not required.
Eight square copper wire through the maximum current is about 40 ~ 80A or so. General normal current by a square 5A or so selected, and the maximum value of about 10A. The smaller the cross-sectional area, the current density can be slightly larger; the larger the cross-sectional area, the current density decreased slightly. Cable carrying capacity: cable carrying capacity refers to a cable line in the transmission of electricity through the amount of current. In the case of thermal stability, when the cable conductor to achieve long-term allowable operating temperature of the cable carrying capacity, known as the cable long-term allowable carrying capacity. Current estimation formulas: 2.5 points multiplied by nine, go up by a straight walk. Thirty-five by 3.. both groups of five points. Conditions have changed, high temperature Jiujiang copper upgrade. Piercing the number of two hundred thirty-four, eight seven six fold full load.
