Abstract
본 고안은 전력선 케이블, 통신 케이블, 광케이블에 모두 적용될 수 있는 난연케이블 이다. 산업이 고도화 되면서 에너지 사용 증가에 따라 전기, 가스등에 의한 화재의 가능성이 높아지고 있고, 따라서 케이블도 난연의 중요도가 높아지고 있다.The present invention is a flame retardant cable that can be applied to power line cables, communication cables, and optical cables. As the industry is advanced, the possibility of fire caused by electricity, gas, etc. increases with increasing energy use, and thus, the importance of flame retardancy is also increasing.
본 케이블은 트레이용 전력케이블에 있어, 절연된 복수개의 선재를 충진재( 폴리프로필렌 또는 종이)와 함께 연합(단면이 둥글게 되도록 하나로 꼼) 시킬 때, 선재 표면 및 충진물 표면에 제1인산암모늄(NH4H2PO4) 분말을 분사시켜 단위 길이당 일정량을 충진 시킨후 IEEE383 (케이블의 난연 정도를 시험하는 국제규격으로, 일정한 공간에서 2.4m 길이의 케이블 10개를 수직으로 세우고 버너로 불을 붙여 타 올라가는 정도를 시험하는 방법으로 이 길이 이내에서 연소가 멈추어야 함) Test를 실시하면 연소 높이가 50cm 에 그치는 획기적인 난연특성을 나타냈다.This cable is a tray power cable. When a plurality of insulated wires are combined together with a filler (polypropylene or paper), the ammonium phosphate (NH 4 ) is added to the wire and the filler surface. H 2 PO 4 ) After spraying the powder to fill a certain amount per unit length, IEEE383 (International standard for testing the flame retardancy level of the cable). Combustion should stop within this length as a test of the degree of ascent.) The test showed a remarkable flame retardant characteristic with a combustion height of only 50 cm.
Description
본 고안은 난연 전력선 케이블에 관한 것으로써, 기존의 케이블은 난연성을 구현하기 위해 피복제에 수산화마그네슘 성분 및 기타 활석성분을 첨가함으로써 케이블의 난연의 특성을 향상 시켰다. 또한 케이블 단면을 원형으로 만들기 위해 삽입하는 충진재도 난연특성을 갖는 물질을 첨가하여 산소지수를 올려 난연특성을 갖도록 하였다. 이러한 케이블의 경우 IEEE383 TEST를 만족시키나, 케이블 자체가 빨리 소화되지 않아, 화재 발생시, 불길을 인접 물체에 전이 시킬 수 있는 위험성을 가지고 있다.The present invention relates to a flame retardant power line cable, and the existing cable improves the flame retardant property of the cable by adding magnesium hydroxide and other talc components to the coating material to realize flame retardancy. In addition, the filler inserted to make the cable cross section is made of flame retardant properties by increasing the oxygen index by adding a material having flame retardant properties. Such a cable satisfies IEEE383 TEST, but the cable itself is not extinguished quickly, and there is a danger that the flame can be transferred to an adjacent object in case of fire.
본 고안은 이상과 같은 문제점을 해소하기 위해, 즉 케이블에 화재가 발생하였을 때 케이블자체에서 능동적으로 화재를 소화하는 특성을 갖춰 빠른 시간 안에, 케이블에 붙은 불이 스스로 소화되도록 하는데 그 특징이 있다.The present invention has the characteristics to solve the above problems, that is, the cable itself has a characteristic of extinguishing the fire actively when a fire occurs, so that the fire attached to the cable is extinguished by itself.
전력케이블에 있어 절연된 도체는 일반 충진물과 함께 연선(단면이 원형으로 꼬아짐)되어지는데 충진재로는 폴리플로필렌, 종이, 기타 충진재가 사용되고, 그 위를 부직포 또는 폴리에스터 계열의 테이프로 감은후 비닐 또는 폴리에틸렌으로 피복을 한다. 충진재로 사용되는 종이는 불이 붙으면 자체적으로 소화되지 못한다. 폴리프로필렌도 자체적으로 소화되지 않고, 불이 붙은 체로 녹아 떨어져 불을 전이 시키기도 한다. 따라서 기존의 케이블의 경우 IEEE383 (국제 케이블 난연특성 시험 규격)을 만족시킨다 하더라도, 초기에 화재로 케이블에 불이 붙었을 경우에는, 케이블에 붙은 화재의 자체 소화시간이 길어 케이블에 의한 주변으로의 화재를 확산시키는 것을 방지하는 못하는 문제점이 있었다.Insulated conductors in power cables are stranded together (general cross-section) along with general fillers. Polyfillene, paper, and other fillers are used as fillers. Cover with vinyl or polyethylene. Paper used as a filler is not able to extinguish itself on fire. Polypropylene is also not extinguished on its own, but also melts in an ignited sieve, causing it to spread. Therefore, even if the existing cable satisfies IEEE383 (International Cable Flame Retardancy Test Standard), if the cable catches fire due to the initial fire, the fire extinguishing time of the fire on the cable is long. There was a problem in preventing the spread.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.
도 1은 전력선케이블의 단면을 나타낸 것으로 충진재 사이에제1인산암모늄(NH4H2PO4)이 첨가되어 있다. 이 케이블의 경우 주변의 요인에 의해 케이블에 불이 붙었을 경우, 충진재의 사이에 첨가된 제1인산암모늄(NH4H2PO4)에 의해 화재가 스스로 소화된다.1 is a cross-sectional view of a power line cable in which ammonium monophosphate (NH 4 H 2 PO 4 ) is added between fillers. In the case of this cable, if the cable catches fire due to surrounding factors, the fire is extinguished by the first ammonium phosphate (NH 4 H 2 PO 4 ) added between the fillers.
제1인산암모늄(NH4H2PO4)의 경우, 공기를 차단시키고, 스스로 온도를 낮추는 작용을 하기 때문에 분말 소화기의 약제로 가장 많이 쓰이고 있으며, 친환경적이고 동, 폴리에틸렌, 기타재료의 물성에 영향을 미치지 않는 물질이다.Ammonium monophosphate (NH 4 H 2 PO 4 ) is most commonly used as a medicament for powder fire extinguishers because it blocks air and lowers the temperature by itself. It is environmentally friendly and affects the properties of copper, polyethylene, and other materials. It does not have a substance.
따라서 충진재 표면에, 불을 소화하는 능력이 뛰어난 제1인산 암모늄(NH4H2PO4)가루를 얇게 도포하면, 케이블에 화재가 발생되더라도 내부의 충진재등은 표면에 도포되어져 있는 제1인산 암모늄(NH4H2PO4)에 의해 공기가 차단되고, 냉각되어져 불이 스스로 꺼지게 되고 화재가 다른 곳으로 전이 되지 않는다.Therefore, if a thin layer of monoammonium phosphate (NH 4 H 2 PO 4 ) powder having excellent fire extinguishing ability is applied to the surface of the filler, even if a fire occurs in the cable, the internal fillers and the like are coated on the surface of the ammonium monophosphate. The air is blocked by (NH 4 H 2 PO 4 ), cooled down, the fire goes out on its own, and the fire does not spread elsewhere.
표1은 각케이블의 도체를 제외한 질량 대비 투입된 제1인산암모늄(NH4H2PO4)의 투입량과 연소길이를 나타낸 것이다.Table 1 shows the input amount and the combustion length of the first ammonium phosphate (NH 4 H 2 PO 4 ) added to the mass excluding the conductor of each cable.
이상에서 상술한 바와 같이 본 고안은 전력케이블, 통신케이블 및 광케이블에 있어 선재를 연합시 제1인산암모늄(NH4H2PO4)을 첨가함으로써 난연특성을 증가시키고 화재발생에 의해 케이블에 불이 붙었을 경우 불꽃의 진행을 억제함으로써 화재를 신속히 소멸시키는 작용을 하여 케이블에 의한 화재의 전이를 최소화 시키는데 그 특징이 있다.As described above, the present invention increases the flame retardancy by adding a first ammonium phosphate (NH 4 H 2 PO 4 ) when the wires are combined in the power cable, the communication cable, and the optical cable. When attached, it has the characteristic of minimizing the transition of fire by cable by acting to extinguish the fire quickly by suppressing the progress of the flame.
