濟南電纜橋架:防火橋架的作用是什么?

  防火橋架的作用是什么?

What is the function of fire resistant cable trays?

  防火橋架是在普通橋架表面噴涂一層防火漆,以起到防火阻燃的作用!其實橋架本身并不會著火,著火的只可能是電纜,防火漆所起到的防火阻燃原理

Fireproof cable tray is sprayed with a layer of fireproof paint on the surface of ordinary cable tray to play a role in fire prevention and flame retardancy! In fact, the bridge itself does not catch fire. What catches fire can only be the cables, and the fire retardant principle played by the fireproof paint

  防火橋架的防護厚度按 / T 10216一2000《電控配電用電纜橋架》表10要求,電鍍大于12μm,熱鍍大于65μm ,噴塑大于50μm,防火大于500μm ,可以用測厚儀測出來。

The protective thickness of the fireproof cable tray shall comply with the requirements of Table 10 of /T 10216-2000 "Cable trays for electrical control and distribution", and the electroplating shall be greater than 12 μ m. Hot plating greater than 65 μ M, spray molding greater than 50 μ m. Fire prevention greater than 500 μ M can be measured using a thickness gauge.

  阻燃防火橋架主要參數
