Bend radius, which is measured to the inside curvature, is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life. The smaller the bend radius, the greater the material flexibility (as the radius of curvature decreases , the curvature increases ).
A minimum bend radius must be observed, and the cable must be supported at regular intervals. The magnesium oxide insulation is hygroscopic , so MICC cable must be protected from moisture until it has been terminated.
Cables must not be bent below their minimum bend radius, [9] [10] which depends upon cable size as expressed in AWG. The table on the right summarizes minimum values typically admitted for SFP+ sustained bend radiuses.
Category 6 and 6A cable must be properly installed and terminated to meet specifications. The cable must not be kinked or bent too tightly; the bend radius should be larger than four times the outer diameter of the cable. [16] The wire pairs must not be untwisted and the outer jacket must not be stripped back more than 13 mm (0.51 in).
Deformation: twisted pair's susceptibility to electromagnetic interference greatly depends on the pair twisting schemes staying intact during the installation. As a result, twisted pair cables usually have stringent requirements for maximum pulling tension as well as minimum bend radius. This fragility of twisted-pair cables makes the ...
The extra width and depth enables cabling to be routed with ease (also helping to maintain the minimum bend radius for fiber and copper cables) and deeper equipment to be utilized. A common feature in IT racks is mounting positions for zero-U accessories, such as power distribution units (PDUs) and vertical cable managers and ducts, that ...
Some cables have requirements for minimum bending radius or proximity to other cables, particularly power cables, to avoid crosstalk or interference. Power cables often need to be grouped separately and suitably apart from data cables, and only cross at right angles which minimizes electromagnetic interference.
Litz wire is a particular type of multistrand wire or cable used in electronics to carry alternating current (AC) at radio frequencies. The wire is designed to reduce the skin effect and proximity effect losses in conductors used at frequencies up to about 1 MHz .
