THW不燃無機防火橋架:

THW型不燃無機防火橋架由無機材料、阻燃材料和玻璃纖維增強材料層飾模而成，產品具有不燃、質輕、強度高、價格低廉等特點。該橋架廣泛應用于電力、石油、石化、冶金、通訊、建筑等行業各種電壓等級電纜的防火保護。

該產品一般用于架空電纜、電纜隧道、電纜夾層、電纜豎井等電纜密集場所的阻火分隔。以防止電纜著火延燃和重要電纜回路的防火(或阻火) 。

THW Non Combustible lnorganic Fireproof Bridge is molded through inorganic material, fire resistantmaterial and glass fiber reinforced material, which has non-inflammable property, light weight, high strengthand low price etc. This crane span structure can be extensively applied in fireproofing protection of cableswith various voltage classes in electrify, petroleum, petrifaction, metallurgy, communications and buildingetc.

The product is often used in fire- resistant separation in intensive cable sites as overground cable, cabletunnel, cable interlayer and cable shaft etc so as to prevent inflaming and extensive- burning of cables andfireproofing(or fire resistance) of important cable return circuit.

施工方法：

將橋架直接安裝在托壁支架上，用專用螺栓連接固定，始、終端及每隔1m間距離用電纜防火專用鎖緊扣和專用捆扎帶固定。?

The crane span structure should be installed on the supporting wall bracket directly, connectedand fastened by special bolt, whose two sides and each distance of 1m can be fastened with cablefireproofing special locking button and special strapping tape.
