Description

해저케이블{Under Sea Cable}Under Sea Cable

본 발명은 해저케이블에 관한 것으로서, 특히 내식성 및 강성이 우수하게 구성한 것이다.The present invention relates to a submarine cable, and is particularly excellent in corrosion resistance and rigidity.

해저케이블은 해수에 설치되는 케이블로서, 염분에 대한 내식성을 가져야 하며, 유체력에 의한 변형되지 않을 정도의 강성을 갖고 있어야 한다.Submarine cables are cables installed in seawater, which must have corrosion resistance against salt and have rigidity that can not be deformed by fluid force.

도 1은 종래 기술에 따른 해저케이블의 단면도이다.1 is a cross-sectional view of a submarine cable according to the prior art.

도 1에 도시된 바와 같이, 해저케이블(1)의 단면을 살펴보면, 해저케이블(1)의 중심에 전도체(11)가 위치하고, 전도체 스크린(13), 절연체(15), 코어 스크린(17), 쉬스(19a, 19b), 절연테이프(21), 금속 보강재(23), 베딩(25), 스틸와이어(27), 베딩(29), 스틸 테이프(31), 외피(33) 순으로 전도체(11)를 감싼다.As shown in FIG. 1, when looking at the cross section of the submarine cable 1, the conductor 11 is located at the center of the submarine cable 1, the conductor screen 13, the insulator 15, the core screen 17, Conductors 11 in order of sheaths 19a and 19b, insulating tape 21, metal reinforcement 23, bedding 25, steel wire 27, bedding 29, steel tape 31, and sheath 33. )

여기에서 스틸와이어(27)는 아머(Armour)로서, 해저케이블(1)이 유체력에 의해 변형되는 것을 방지하는 기능을 갖고 있다.The steel wire 27 is an armor, and has a function of preventing the submarine cable 1 from being deformed by the fluid force.

종래 기술에 따른 해저케이블의 스틸와이어는 아연도금된 선재를 이용한다. 아연도금 선재는 선재의 부식을 방지하기 위해 선재에 아연을 도금한 것으로서, 아연의 희생방식작용을 이용하여 선재의 부식을 막는다.Steel wires of submarine cables according to the prior art use galvanized wire. Galvanized wire rod is a zinc plated wire to prevent corrosion of the wire rod, using the sacrificial anticorrosive action of zinc to prevent corrosion of the wire rod.

하지만, 이와 같은 아연의 희생방식작용은 시간이 지날수록 약해지며, 결국 선재는 부식하게 된다. 특히 도금상태의 불량 또는 스크래치에 의해 도금이 벗겨진 부분이 발생할 경우에, 아연도금 선재의 내식성을 기대하기에 어려움이 있다.However, this sacrificial anticorrosive effect of zinc weakens with time, and eventually the wire rod is corroded. In particular, in the case where the plating is peeled off due to scratching or scratching of the plating state, it is difficult to expect the corrosion resistance of the galvanized wire.

더불어 해수에 설치된 해저케이블의 경우, 유체력과 해수의 염분은 스틸와이어의 수명을 단축시키는 요소로 작용하게 된다. 이와 같이 스틸와이어의 수명이 단축됨으로써, 해저케이블의 내구성 또한 짧아지게 된다.In addition, in the case of the submarine cable installed in the seawater, the fluid force and salt of the seawater act as a factor to shorten the life of the steel wire. As the life of the steel wire is shortened, the durability of the submarine cable is also shortened.

본 발명은 앞에서 설명한 바와 같은 종래의 기술의 문제점을 해결하기 위하여 발명된 것으로서, 종래의 아연도금 선재보다 내식성이 우수하며 또한 강성 또한 우수한 재질로 아머를 형성한 해저케이블을 제공하는 데 그 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, an object of the present invention is to provide a submarine cable in which the armor is formed of a material having superior corrosion resistance and rigidity than conventional galvanized wire. .

상기와 같은 목적을 달성하기 위한 본 발명의 해저케이블은 중심에 위치한 전도체를 감싸 보호하는 보호층들 중에 FRP 와이어들을 연선하여 튜브형태로 감싸는 아머(Armour)를 포함하는 것을 기술적 특징으로 한다.The submarine cable of the present invention for achieving the above object is characterized in that it comprises an armor (Armour) wrapped in the form of a tube by twisting the FRP wires of the protective layer surrounding the protective conductor located in the center.

또한, 본 발명의 바람직한 실시예에 따르면, 튜브 형태로 연선된 상기 FRP 와이어들에는 레진이 도포된다.In addition, according to a preferred embodiment of the present invention, a resin is applied to the FRP wires stranded in the form of a tube.

앞서 설명한 바와 같이, 본 발명의 해저케이블은 내식성이 우수하며 강성을 갖는 FRP 재질의 선재를 이용하여 아머를 형성함으로써, 해저케이블의 내식성 및 내구성을 향상시킬 수 있다는 장점이 있다.As described above, the submarine cable of the present invention has an advantage of improving corrosion resistance and durability of the submarine cable by forming an armor using a wire rod made of FRP material having excellent corrosion resistance and rigidity.

아래에서는 본 발명에 따른 해저케이블의 양호한 실시예를 첨부한 도면을 참조로 하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the submarine cable according to the present invention will be described in detail.

An armor 127 made of an FRP wire 151 is formed outside the bedding 125, and the outer surface of the armor 127 is wrapped in the order of the bedding 129, the steel tape 121, and the outer shell 133.

여기에서, 연선된 FRP 와이어(151)들을 튜브형태를 제조하여 설치한 아머(127)는 아머의 안쪽에 위치한 구성요소들을 감싼다. 그리고 FRP 와이어(151)에 레진(153)을 도포하여 접착성을 향상시키고 수분 침투억제 효과를 얻을 수 있다.Here, the armor 127, which is formed by installing the stranded FRP wires 151 in the form of a tube, wraps the components located inside the armor. In addition, the resin 153 may be applied to the FRP wire 151 to improve adhesiveness and to obtain a moisture penetration inhibitory effect.
