球墨鑄鐵海底電纜保護(hù)管是可有效保護(hù)海底電力電纜和光纜，避免電纜和光纜遭受外部機(jī)械損傷及破壞，如礫石、滾石、沉積物、浮游船骸、浮冰、底拖網(wǎng)漁船、網(wǎng)箱漁排養(yǎng)殖、船錨、拖錨、冰山、風(fēng)暴潮、潮汐、地震等的破壞和損傷。該產(chǎn)品每節(jié)有效長度為500mm-1000mm，也可以按要求自定義長度，以哈夫型球鉸連接，相連兩節(jié)保護(hù)管夾角可達(dá)25°左右，可多方位旋轉(zhuǎn)，使海底電纜和光纜有一定的彎曲靈活性，防止打扭。由于該產(chǎn)品施工方便、耐腐蝕，廣泛應(yīng)用于海底電纜和光纜的保護(hù)和改造工程。

  產(chǎn)品特點(diǎn):

  ①便于運(yùn)輸和施工。

  球墨鑄鐵海底電纜保護(hù)管使用托盤包裝固定，方便施工船的運(yùn)輸裝載，每節(jié)有效長度500mm的長度使海底電纜鋪設(shè)施工過程中更顯便捷，人力勞動強(qiáng)度低，節(jié)省造價。

  ②抗老化、耐腐蝕，適用于在海底等各類防護(hù)要求高的環(huán)境下鋪設(shè)。

  球墨鑄鐵海底電纜保護(hù)管表面涂有防腐油漆，不易受海水的腐蝕，不容易腐爛，保護(hù)期長。傳統(tǒng)鐵磁材料保護(hù)管在海水中比較容易銹蝕，經(jīng)過一段時間海水的腐蝕，保護(hù)管銹蝕、變薄、變脆甚至腐爛，失去保護(hù)性能。

  ③機(jī)械強(qiáng)度高，保護(hù)海底電纜。

  球墨鑄鐵海底電纜保護(hù)管具有良好的機(jī)械強(qiáng)度和沖擊耐受力，能抵抗海水的壓力和外來機(jī)械沖擊，保護(hù)海底電纜和光纜。

  ④外形結(jié)構(gòu)科學(xué)，適用于海底電纜后期保護(hù)和檢修。

  球墨鑄鐵海底電纜保護(hù)管外形專為增加保護(hù)管對海底附著力而設(shè)計(jì)：球鉸結(jié)構(gòu)使保護(hù)管及被保護(hù)的海底電纜或光纜牢固附著在海床下和巖礁、礫石中，不易被海底洋流或潮汐來回往復(fù)推動摩擦滾動而受損傷;每節(jié)有效長度500mm，以哈夫型球鉸連接，相連兩節(jié)保護(hù)管夾角25°左右，可多方位旋轉(zhuǎn)，能有效防止海底電纜扭曲或彎曲半徑過小而引起海底電纜絕緣層結(jié)構(gòu)受損。

  ⑤抗震抗沖擊

  球墨鑄鐵海底電纜保護(hù)管具有抗震和抗沖擊性能，當(dāng)海底發(fā)生地震或海床變遷時，由于保護(hù)管內(nèi)球鉸可多方位旋轉(zhuǎn)，連接吸收了振動或沖擊能量，能夠有效保護(hù)電纜和光纜免遭振動或沖擊破壞。

  ⑥適用于更大規(guī)格海底電纜

  球墨鑄鐵海底電纜保護(hù)管生產(chǎn)方便快捷，可以按電纜規(guī)格定做，適用于35kV、110kV、220kV、500kV海底電纜用保護(hù)套管。

  適用范圍:

  本產(chǎn)品根據(jù)國際大電網(wǎng)會議第21-06研究會工作小組《關(guān)于就海纜保護(hù)“參考規(guī)程”的建議》，對任何重要的輸電線路，都必須對海底電纜和光纜加以保護(hù)的要求而設(shè)計(jì)。適用于電力、通信、海上石油開采用保護(hù)管，廣泛應(yīng)用于海底電纜的鋪設(shè)，適用于在海床上電纜保護(hù)、海床下電纜保護(hù)、海底管線交叉跨越處電纜保護(hù)、巖礁上電纜保護(hù)。

  套管連接:

  球墨鑄鐵海底電纜保護(hù)管管間采用半邊管對扣后用防銹螺絲固定，套管間用球形鉸鏈(大球套小球)連接。

Product description:
The WT-Pipe submarine cable protectors are formed out of two identical half-shells which form a self-locking articulated pipe. For a quick installation the WT Cable Protection System can be installed boltless, It is also possible to use bolt to increase strength further,There are various structures to choose from.Protectorshell articulated pipe is manufactured from ductile iron which retains the corrosion resistance of traditional cast iron but is far stronger. The WT Cable Protection System has been designed as a simple and cost effective cable protection system for areas where conventional burial or trenching methods prove to be uneconomical and/or not achievable due to bottom conditions. During installation WT-Pipe can either be fitted directly to the submarine product and floated-out or can alternatively be installed by divers once the submarine product has already been laid. 
Our ductile Articulated Pipes are made highly durable.The ductile Articulated Pipes are designed in-house and are subject to rigorous quality and durability testing to ensure the highest quality and durability.

Ductile cast iron cable protection system used for: 
Protection of Power Cables\Protection of Telecom Cables\Protection of Water Pipes\Typical installation locations include but are not limited to shore end, subsea crossings and areas with extreme environmental conditions, such as areas with rock formations, coral reefs and coastlines which are subject to severe erosion.

Features：
Split Design - Ductile cast iron half shells\Easy handling and fast assembly\Well tested strong locking mechanism - Do not require bolting!\Build in bend restriction\Avoids abrasion of the cable\Protection in free span areas\Supports rock dumping \Environment friendly - No special permits required\The Ductile Cast Iron pipes are certified with chemical and mechanical properties and are fully traceable.
