Description
제 1 도는 본 고안의 요부를 나타낸 절개 사시도이다.1 is a perspective view showing the main portion of the present invention.
제 2 도는 전력 케이블의 횡단면도.2 is a cross-sectional view of a power cable.
본 고안은 선심식별(線心識別) 및 전기적 접속이 우수한 고압전력케이블에 관한 것이다.The present invention relates to a high-voltage power cable excellent in wire core identification and electrical connection.
현재 사용 중인 6,600V 이상의 고압전력케이블에 있어서 선심식별방법은 주로 제 2 도와 같이 연동(軟銅)차폐 테이프(a)상에 색별 프라스틱(또는 綿) 테이프(b)(6.6KV급의 경우 백, 적, 청색)를 감아서 식별하고 있다.For 6,600V or higher high voltage power cables currently used, the core detection method mainly uses color-coded plastic (or 綿) tape (b) (white, red in case of 6.6KV class) on interlocking shielding tape (a) as shown in the second diagram. , Blue) to identify.
따라서 이는 절연체상에 외부 반도전성 테이프(C)와 선심식별용 색별테이프(b)등 2중으로 테이프를 권착하게 되므로 작업성의 저하 및 자재비의 증가는 물론 완성 외경이 커지는 결점이 있고 또한 각심의 연동 차폐 테이프 외경에 선심식별테이프를 권착함으로써 각 심선 연동차폐테이프가 선심식별테이프에 의해 전기적으로 접속이 안되어 케이블 공사시 심선마다 각각 접지를 해야 되는 등 많은 문제점이 있었던 것이다.Therefore, since the tape is doubled on the insulator, such as an external semiconductive tape (C) and a color discriminating tape (b) for wire core identification, there is a disadvantage in that workability and material cost are increased, as well as the finished outer diameter is increased. By attaching the core ID tape to the outer diameter of the tape, each core wire interlocking shield tape was not electrically connected by the core ID tape, so that each core wire had to be grounded at the time of cable construction.
본 고안은 이러한 문제점을 해결코저 한 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다. 도체(1) 외면에 내부 반도전층(2)을 도포하고 그 위에 절연체(3)를 포설한 것에 있어서 상기 절연체(3) 외경에 권회한 외부반도전성테이프(4)의 표면에 일정폭의 색별선(6.6KV급의 경우 백색, 적색, 청색)(5),(5'),(5")(색별선 대신에 문자 또는 기호에 색체를 넣을 수도 있다)을 착색 또는 인쇄하여 선심을 식별토록 구성한 것으로 도면 중 미설명부호 6은 연동(軟銅)차폐테이프, 7은 개재물(介在物), 8은 바인더 테이프, 9는 비닐 쉬이즈이다.The present invention has been made to solve these problems and described in detail based on the accompanying drawings as follows. In the coating of the inner semiconducting layer 2 on the outer surface of the conductor 1 and laying the insulator 3 thereon, a color separation line having a predetermined width on the surface of the outer semiconducting tape 4 wound around the outer diameter of the insulator 3. (In case of 6.6KV class, white, red, blue) (5), (5 '), (5 ") (colors may be added to letters or symbols instead of the color line) In the drawings, reference numeral 6 denotes an interlocking shielding tape, 7 an inclusion, 8 a binder tape, and 9 a vinyl sheath.
이와같이 된 본 고안은 외부반도전성테이프(4)의 표면에 색별선을 넣는 것이므로 반도전성테이프(4) 하나로서 반도전성과 선심식별을 겸하게 되어 종래와 같이 외부반도전성테이프와 선심식별용 테이프를 각각 별도로 권회하던 것보다 작업공정이 줄어들게 되어 작업성이 양호하고 또한 자재비의 절감을 기할 수 있음과 아울러 선심식별테이프의 생략으로 완성외경이 감소됨은 물론 공사시 1 심에만 접지를 하여도 각 심선연통차폐테이프 표면이 서로 밀착되어 전기적으로 접속되어 있으므로 차폐테이프의 전류용량을 증가시키는 등의 효과를 기할 수 있다.Since the present invention is to put a color separation line on the surface of the outer semiconducting tape (4), the semiconducting tape (4) combines the semiconductivity and the core core identification, respectively. Work process is reduced compared to winding separately, and workability is good and material cost can be reduced, and finished outer diameter is reduced by omission of core identification tape. Since the tape surfaces are in close contact with each other and electrically connected, the effect of increasing the current capacity of the shielding tape can be obtained.
