What is the name of this trunking? The
Trough type (fully enclosed) cable bridge common specifications are: Currentspecificationsofchannel-stylecabletray (fullyclosed-end): 250 ××××× 200 Cascade cable bridge common specifications are: 100 × × × × × × × × × × × × 400 Cable Bridge Specification Representation: XQJ --- Form - Category - Specifications XQJ indicates that the series of lines is in the form of a structure (the capital letter T of the first Chinese Pinyin is a step type, P is the tray type C (With Arabic numerals plus English alphabet) Specifications Specifications or specifications Serial number (indicated by Arabic numerals) Cable tray size selection and calculation: Cable bridge load G Total calculation G Q. q. q3 ... are the weight per unit length (kg / m) of each cable n. n. n3 ... ... for the corresponding number of cables G should be less than the cable bridge allowable load (see the load curve chart) when the cable bridge in the outdoor or with a shield, should also be included in the water load and wind load and other factors. Cable bridge width d degree calculation: . the power cable b = n1 (d1 + k1) + n2 (d2 + k2) + n3 (d3 + k3) + ... where: d. d. d3. N. n. n3 ... is the number of the corresponding cable diameter; k. k. k3 ... for the cable spacing (K value should not be less than the minimum D / 4) control cable bridge width b calculation: (general cable bridge filling rate of about 40%) cable total load area: S0 = n1π (d1 / 2) 2 + n2π (d2 / 2) 2 +. The required cross-sectional area of ??the bracket: S = S0 / 40% S = S / h = S0 / 40% h Where: h is the cable bridge height
