Cable tray width b determined with the different power cables and control cables work system rather different. Since the power cables in the bridge are generally single-level emission standard galvanized tray, so its installation bridge width b is: b = n1 (d1 + k1) + n2 (d2 + k2) + n3 (d3 + k3) + ...... wherein: d1, d2, d3 ...... within the outer diameter of the cable tray of various units of mmn1, n2, n3 ...... above the number of the same kind of model specifications of the cable. K1, k2, k3 ...... pitch of said cable when placed. Its value should be greater than 1/4 of the minimum diameter of the cable.
