電纜溝防火隔板設(shè)置要求

Requirements for setting fire barriers in cable trenches

　　電纜溝防火隔板的設(shè)置要求主要包括以下幾點(diǎn)：

The requirements for setting up fire barriers in cable trenches mainly include the following points:

　　防火隔板的適用場(chǎng)所：防火隔板主要適用于各類電壓等級(jí)的電纜在支架或橋架上敷設(shè)時(shí)的防火保護(hù)和耐火分隔，大量應(yīng)用在發(fā)電廠、化工企業(yè)、鋼鐵冶煉企業(yè)、礦山等電纜密集場(chǎng)所的電纜工程。

Applicable places for fire barriers: Fire barriers are mainly used for fire protection and fire-resistant separation of cables of various voltage levels when laid on brackets or bridges. They are widely used in cable engineering in cable intensive places such as power plants, chemical enterprises, steel smelting enterprises, and mines.

　　隔板設(shè)置間距：對(duì)于阻燃電纜，在電纜溝每隔80~100m處設(shè)置一個(gè)隔斷；對(duì)于非阻燃電纜，宜每隔60m設(shè)置一個(gè)隔斷。一般設(shè)置在臨近電纜溝交叉處。

Partition spacing: For flame-retardant cables, a partition should be set every 80-100m in the cable trench; For non flame retardant cables, it is advisable to set up partitions every 60m. It is generally set near the intersection of cable trenches.

　　安裝方式：防火墻的安裝方式為兩側(cè)采用標(biāo)準(zhǔn)厚度的防火隔板封隔、中間采用無機(jī)堵料、防火包或耐火磚堆砌，其厚度根據(jù)產(chǎn)品的性能而定，一般不小于250mm。

Installation method: The installation method of the firewall is to use standard thickness fireproof partitions on both sides, inorganic blocking materials, fireproof bags or refractory bricks in the middle, and the thickness depends on the performance of the product, generally not less than 250mm.

　　電纜包裹要求：防火墻內(nèi)的電纜周圍必須采用不得小于20mm的有機(jī)堵料進(jìn)行包裹。

Cable wrapping requirements: The cables inside the firewall must be wrapped with organic blocking material not less than 20mm around them.

　　排水孔洞：防火墻頂部用無機(jī)防火堵料填平整，并加蓋防火隔板，底部必須留有兩個(gè)排水孔洞，排水孔洞處可利用磚塊砌筑。

Drainage holes: Fill the top of the firewall with inorganic fireproof blocking material and cover it with fireproof partitions. Two drainage holes must be left at the bottom, and bricks can be used to build the drainage holes.

　　其他要求：防火隔板應(yīng)存放在通風(fēng)干燥處，避免雨淋，運(yùn)輸時(shí)應(yīng)防止雨淋，搬運(yùn)時(shí)應(yīng)避免損壞。

Other requirements: Fire barriers should be stored in a ventilated and dry place to avoid rain, and should be protected from rain during transportation. Damage should be avoided during handling.

　　以上是電纜溝防火隔板的設(shè)置要求，具體設(shè)置還需根據(jù)實(shí)際情況和相關(guān)規(guī)范進(jìn)行調(diào)整。

The above are the requirements for setting fire barriers in cable trenches, and the specific setting needs to be adjusted according to the actual situation and relevant specifications.
