따라서, 상기 시스절연체(20)가 피크 폴리머소재로 이루어짐으로써, 시트열선의 내구성과 인장강도가 상향되게 된다. 그리고, 상기 피크 폴리머 소재는 탄소섬유와 유리섬유가 10몰%로 포함되어 구비되는 것이 바람직하다.Therefore, the durability and the tensile strength of the sheet heating wire are increased by making the sheath insulator 20 made of the peak polymer material.

이때, 상기 외부심선(15)이 정연식 또는 쉴드형으로 구비됨으로써 단면적에 보다 많은 양의 심선이 내재됨으로써 얇게 형성되더라도 더 향상된 전기적 물리적 특성이 나타나게 된다.At this time, since the outer core wire 15 is provided in a regular or shielded shape, a larger amount of core wire is contained in the cross-sectional area, so that even if the outer core wire 15 is formed thin, improved electrical and physical characteristics are exhibited.

그리고, 상기 외부단심선(16)이 구성하는 정연식 구조는 도 3에 도시된 바와 같이, 상기 중앙심선(11)의 외주연에 상기 외부단심선(16)이 인접하여 감싸는 구조가 적층되어 구비됨으로써, 일반적인 집합식 구조보다 내구성이 높아지게 된다. 여기서, 상기 집합식 구조는 일정하게 형성되지 않는 구조의 상기 도체심선(10)이 노출이 일정치 않는 특정부위가 외력에 의해 쉽게 손상되게 된다.As shown in FIG. 3, the regular core structure of the outer core wire 16 has a structure in which the outer core wire 16 is adjacent to and surrounded by the outer periphery of the center core wire 11 , The durability becomes higher than that of a general gathering structure. In this case, a certain portion of the conductor core wire 10 having a structure in which the aggregate structure is not constantly formed is not easily exposed, is easily damaged by an external force.

한편, 쉴드형은 인접된 상기 외부단심선(16)이 상기 중앙심선(11)을 나선구조로 감싸며 형성된 구조이다.On the other hand, the shield type is a structure in which the adjacent outer single core wires 16 surround the center core wire 11 in a spiral structure.

상기 중앙심선(11)과 상기 외부단심선(16)에 구비된 바니쉬(11b)와 외부바니쉬(16b)는 우레탄, 테프론, 나일론 중 어느 하나의 소재로 구비됨으로써, 절연특성과 내마모성 등이 보강되며, The varnish 11b and the outer varnish 16b provided on the center core wire 11 and the outer core wire 16 are made of any one of urethane, Teflon, and nylon, thereby reinforcing insulation properties and abrasion resistance ,

상기 외부심선(15)에는 상기 도체심선(10)의 인장강도가 보강되도록 대칭구조로 구비된 케블라소재의 보강재(17)가 구비됨으로써, 잦은 눌림이나 외력이 작용하는 시트열선이 보호되게 된다.
The outer core wire 15 is provided with a Kevlar reinforcing material 17 having a symmetrical structure so as to reinforce the tensile strength of the conductor core wire 10, thereby protecting the sheet heating wire from frequent pressing or external force.
