Submarine cable protection bend restrictor is designed to prevent bending beyond a set minimum bending radius (MBR) under a certain design load in both static and quasi-dynamic applications. They are made up of many interlocking parts that combine to produce a semi-rigid curved structure.
Submarine cable bending limiter is made from the polymer material polyurethane, and its main goal is to provide a durable and cost-effective solution that reduces the cost of cable protection thanks to its special design of two interlocking mechanisms. Because polyurethane features unique mechanical properties, it can withstand the harsh marine environment and resist high impact, wear and corrosion.
These interlocking polyurethane bend limiter housings can also be used as part of a cable protection system, as well as to protect and stabilize longer cable segments for shore landings or unembedable rocks or challenging seafloor.
Bend Restrictor Application Fields
• submarine communication cable：Applied in submarine optical cable systems for international Internet and telephone communications to ensure the stability and security of data transmission.
• oil and gas pipeline：Employed in subsea pipeline systems transporting oil and gas to ensure safe and efficient energy transmission.
The Bend Restrictor specification is not standard, and the MBR varies with the length of the cable. A bend limiter is applied to ensure that the bend radius of the cable does not exceed the minimum bend radius defined by the manufacturer.
