当电缆在出产厂房内明敷时, 应注意:
( 1) 沿墙壁、构架、天花板等处敷设电缆输送机时, 应在下列各处将电缆固定:垂直或超过45°倾斜敷设, 电力电缆为
2m, 控制电缆为1m; 水平敷设的直线段, 除在直线段的两端固定外, 中间固定间距, 电力电缆为1m, 控制电缆为0. 8m; 电缆头的颈端, 电缆接头两侧; 线路转弯时, 在电缆转弯的两端; 通过伸缩缝时, 沿缝的中央线两侧0. 75—1m 处。
( 2) 电力电缆相互间的净距为35mm, 但不小于电缆的外径。
( 3) 明设在厂房内及不填土的电缆沟内的电缆应剥除麻袋, 恺装电缆应涂防腐漆。
( 4) 电缆由支架引向设备或配电装置时, 在接近处应与设备或配电装置垂直, 并在转弯处作牢靠的固定。
When the cable Ming fu in production, should be paid attention to:(1) along the wall, the place such as architecture, ceiling, cable laying, should be everywhere in the following the cable is fixed: vertical or 45 ° inclined cable laying, power cable2 m, control cable of 1 m;Run level of straight section, except at the ends of the line segment fixed middle fixed spacing, power cable is 1 m, control cable for 0. 8 m;The neck end of the cable head, cable joint on both sides;Turning around a corner on the cable lines at both ends;Through the expansion joints, along the seam on both sides of Central Line of 0. 75-1 m.(2) power cable between the net distance of 35 mm, but not less than the outer diameter of cable.(3) is located in the factory and do not fill in cable trench inside the cable should be stripped sacks, kai cables should be painted anticorrosive paint.(4) cable by stent to equipment or power distribution equipment, and the device should be in close to place or vertical distribution equipment, then make firmly down on a bend. |
