球墨铸铁海底电缆保护管

  球墨铸铁海底电缆保护管是可有效保护海底电力电缆和光缆，避免电缆和光缆遭受外部机械损伤及破坏，如砾石、滚石、沉积物、浮游船骸、浮冰、底拖网渔船、网箱渔排养殖、船锚、拖锚、冰山、风暴潮、潮汐、地震等的破坏和损伤。该产品每节有效长度为500mm-1000mm，也可以按要求自定义长度，以哈夫型球铰连接，相连两节保护管夹角可达25°左右，可多方位旋转，使海底电缆和光缆有一定的弯曲灵活性，防止打扭。由于该产品施工方便、耐腐蚀，广泛应用于海底电缆和光缆的保护和改造工程。

  产品特点:

  ①便于运输和施工。

  球墨铸铁海底电缆保护管使用托盘包装固定，方便施工船的运输装载，每节有效长度500mm的长度使海底电缆铺设施工过程中更显便捷，人力劳动强度低，节省造价。

  ②抗老化、耐腐蚀，适用于在海底等各类防护要求高的环境下铺设。

  球墨铸铁海底电缆保护管表面涂有防腐油漆，不易受海水的腐蚀，不容易腐烂，保护期长。传统铁磁材料保护管在海水中比较容易锈蚀，经过一段时间海水的腐蚀，保护管锈蚀、变薄、变脆甚至腐烂，失去保护性能。

  ③机械强度高，保护海底电缆。

  球墨铸铁海底电缆保护管具有良好的机械强度和冲击耐受力，能抵抗海水的压力和外来机械冲击，保护海底电缆和光缆。

  ④外形结构科学，适用于海底电缆后期保护和检修。

  球墨铸铁海底电缆保护管外形专为增加保护管对海底附着力而设计：球铰结构使保护管及被保护的海底电缆或光缆牢固附着在海床下和岩礁、砾石中，不易被海底洋流或潮汐来回往复推动摩擦滚动而受损伤;每节有效长度500mm，以哈夫型球铰连接，相连两节保护管夹角25°左右，可多方位旋转，能有效防止海底电缆扭曲或弯曲半径过小而引起海底电缆绝缘层结构受损。

  ⑤抗震抗冲击

  球墨铸铁海底电缆保护管具有抗震和抗冲击性能，当海底发生地震或海床变迁时，由于保护管内球铰可多方位旋转，连接吸收了振动或冲击能量，能够有效保护电缆和光缆免遭振动或冲击破坏。

  ⑥适用于更大规格海底电缆

  球墨铸铁海底电缆保护管生产方便快捷，可以按电缆规格定做，适用于35kV、110kV、220kV、500kV海底电缆用保护套管。

  适用范围:

  本产品根据国际大电网会议第21-06研究会工作小组《关于就海缆保护“参考规程”的建议》，对任何重要的输电线路，都必须对海底电缆和光缆加以保护的要求而设计。适用于电力、通信、海上石油开采用保护管，广泛应用于海底电缆的铺设，适用于在海床上电缆保护、海床下电缆保护、海底管线交叉跨越处电缆保护、岩礁上电缆保护。

  套管连接:

  球墨铸铁海底电缆保护管管间采用半边管对扣后用防锈螺丝固定，套管间用球形铰链(大球套小球)连接。

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.

Specifications：
1.Materal: Ductile Iron
2.Size: ID50mm-ID400mm and Per Your Requirement
3.Wall thickness: 8mm-20mm and Per Your Requirement
4. Surface Treatment：Bitumen Painting

We can design and manufacture different size of Articulated Pipes to suit different cable size with minimum bending radius requirements.All products can be customized.
