梯式電纜橋架的產品說明

  梯式電纜橋架的產品說明:
  Ladder type cable tray of product description:
  1)電纜橋架、線槽及其支吊架使用在有腐蝕性環(huán)境中,應采用耐腐蝕的剛性材料制造,或采取防腐蝕處理,防腐蝕處理方式應滿足工程環(huán)境和耐久性的要求。
  Steam-water 1) cable tray, trough and its use in corrosive environment, the corrosion resistance of the rigid materials should be adopted, or corrosion resistance, anti-corrosion treatment shall meet the requirements of engineering environment and durability.
  2)電纜橋架在有防火要求的區(qū)段內,可在電纜梯架、托盤內添加具有耐火或難燃性能的板、網等材料構成封閉或半封閉式結構,并采取在橋架及其支吊架表面涂刷防火涂層等措施,其整體耐火性能應滿足有關規(guī)范或標準的要求。梯式電纜橋架
  2) cable bridge, there is a requirement for fire prevention in the segment can be added within the cable ladder, tray with fire or flame retardant performance of the plate, the material such as network forms a closed or semi-closed structure, and take in the steam-water bridge and its surface besmear to brush fire retardant coating, its overall refractory performance should meet the requirements of relevant national norms or standards.
  3)在工程防火要求較高的場所,不宜采用鋁合金電纜橋架。
  3) the demand is higher in the engineering in place, unfavorable use aluminum alloy cable tray.
  4)電纜梯架寬度和高度的選擇應符合填充率的要求,電纜的梯架的填充率在一般情況下,電力電纜可取40%~50%,控制電纜可取50%~70%,且宜預留10%~25%工程發(fā)展裕量。
  4) cable ladder width and height of choice should accord with the requirement of fill rates, cable ladder filling rate in the general case, power cable desirable 40% ~ 50%, and control cable desirable 50% ~ 70%, 10% ~ 25% and well reserved engineering development margin.
  5)在選擇電纜梯架的荷載等級時,電纜橋架的工作均布荷載不應大于所選電纜橋架荷載等級的額定均布荷載,如果電纜橋架的支吊架的實際跨距不等于2m 時,則 工作均布荷載應滿足要求。
  5) when choosing cable ladder load level, the cable tray work uniformly distributed load should not be greater than the selected uniformly distributed load rating of the cable bridge load level, if the actual span cable tray of steam-water is not equal to 2 m, the uniformly distributed load work shall meet the requirements.
  6)各種組件及支吊架在滿足相應荷載的條件下,其規(guī)格尺寸應與托盤、梯架的直線段、彎通系列相匹配。
  6) in steam-water various components and meet the corresponding load conditions, the size should be with a straight run of tray, ladder, curved series matching.
  7)在選擇電纜橋架的彎通或引上、引下裝置時,不應小于電纜橋架內電纜小允許彎曲半徑。
  7) in the selection of cable tray bending or tilt, guide device, should not be less than the minimum allowable bending radius in cable tray.
