본 발명은 수밀성 절연 전선의 제조 방법에 관한 것이다.The present invention relates to a method for producing a watertight insulated wire.

일반적으로 수침 상태로 포설된 케이블은 물론이고, 옥외에 설치된 저, 고압 배전선 등이 있어서, 도체 소선간에 수분이 침투하면 도체소선을 산화시키게 되므로 단지 쉬스 부분만을 수밀시키는 것만으로는 그 목적을 달성할 수 없기 때문에 도체 연선 간극에 수밀성의 혼화물을 충진시키는 방법이 고려되어 왔다.In general, there are low-voltage and high-voltage distribution cables installed outdoors, as well as cables that are immersed in water, and when moisture penetrates between conductor wires, the conductor wires are oxidized. Since it is impossible, a method of filling a watertight blend into the conductor strand gap has been considered.

따라서 도체 연선 간극에 수밀 혼합물을 충진함에 있어서, 종래에는 연선기의 연선전에 충진시키거나 또는 연선후 가압 충진하는 방법이 주로 사용되어 왔다.Therefore, in filling the watertight mixture in the conductor strand gap, conventionally, a method of filling the strand before the twisted pair of the twisted pair or after the strand strand has been mainly used.

그러나 이 경우 연선도체의 최외측에 수밀 혼합물이 잔류하게 되어 연선 도체가 켑스턴이나 가이드 롤러등을 통과하여 권취될 때 연선도체상의 수밀 혼합물이 떨어져 나가거나 주변 장치등을 오염시키고, 수밀성이 저하되는 폐단이 있었다.However, in this case, the watertight mixture remains on the outermost side of the stranded conductors, and when the stranded conductors are wound through the stanston or guide roller, the watertight mixture on the stranded conductors falls off or contaminates the peripheral equipment, and the watertightness is deteriorated. There was a dissolution.

본 발명은 이와 같은 종래의 문제점을 개선하기 위하여 연구된 것으로서, 제1차 공정에서 도체 중심소선을 수밀 테이프로 종점 후 각 소선간에 수밀성 혼화물을 가압 충진한 다음, 보호용테이프를 피복시켜 수밀재가 충진된 연선도체를 안전하게 권취하여 1차 연선 공정을 완료한 후, 제2차 절연 공정에서 상기 피복된 보호용 테이프를 탈피시킨 후 다시 수밀 테이프를 종첨하여 절연압출시킨 것을 특징으로 하는 것이다.The present invention has been studied to improve such a conventional problem, in the first process, after the end of the conductor center element wire with a water-tight tape, after filling the water-tight blends between each element wire, and then covered with a protective tape to fill the water-tight material After the stranded conductor is safely wound and completed the first stranded wire process, the coated protective tape is peeled off in the second insulation process, and the watertight tape is terminated again to insulate and extrude.

이하 본 발명을 첨부 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 의한 전선 제조 방법의 제1차 연선공정도로서, 도체중심소선(1)에 수밀 테이프(2)를 종첨하고 연선기(3)로 각 도체소선과 연선시켜 이것을 가열장치(4)를 통하여 예비가열시킨 다음, 수밀혼화물가압장치(5)에서 수밀재(6)를 130℃의 온도에서 10Kg/Cm의 압력으로 가압충진시키고, 그위에 보호용테이프(7)를 피복시켜 권취함으로써 제1차 연선공정을 완료하게 된다.FIG. 1 is a first twisted pair process diagram of a wire manufacturing method according to the present invention, in which a watertight tape 2 is terminated in a conductor center wire 1 and twisted with each conductor element wire using a stranding machine 3 so as to be heated. After preheating through), the watertight mixture pressurized device 5 is pressurized and filled at a pressure of 10 Kg / Cm at a temperature of 130 ° C., and the protective tape 7 is coated thereon and wound up. The first twisted pair process is completed.

제2도는 본 발명에 의한 제2차 절연공정으로서, 상기 연선이 완료된 전선(11)에서 상기 피복된 보호용테이프(7)를 먼저 제거하고, 수밀테이프(8)을 다시 종첨한 뒤, 공지된 방법으로 절연압출기(9)에서 절연 압출한 후 ,가교장치(10)를 거쳐 2차 절연공정을 완료하게 된다.2 is a secondary insulation process according to the present invention, in which the coated protective tape 7 is first removed from the wire 11 on which the stranded wire is completed, and the watertight tape 8 is again terminated. After insulation extrusion from the insulation extruder (9), the secondary insulation process is completed via the cross-linking device (10).

이와 같은 공정을 거쳐 제조되는 본 발명의 전선 제조 방법에 의하면, 1차 연선공정에서 수밀제(6)를 충진시킨 뒤 2차 절연공정으로 이관되기 전에 수밀재(6)의 외부에 보호용테이프(7)를 감아줌으로서, 수밀재(6)가 충진된 전선(11)이 깨끗하고 안전하게 귄취되어 2차 절연공정을 거치게 되는 효과가 있다.According to the electric wire manufacturing method of the present invention manufactured through such a process, the protective tape (7) outside the watertight member (6) after filling the watertight agent (6) in the primary stranding process and before being transferred to the secondary insulation process. ), The electric wire 11 filled with the watertight member 6 is cleanly and securely picked up and has a second insulating process.

이상과 같이 본 발명의 수밀성 절연전선의 제조방법은 수밀 효과가 보다 우수한 전선을 제조할 수 있는 신규한 발명이다.As mentioned above, the manufacturing method of the watertight insulated wire of this invention is a novel invention which can manufacture the electric wire which is more excellent in a watertight effect.
