At both ends of the tube 2, an enlarged portion 5 is formed which is slightly larger than the diameter of the tube 2 for the sealing structure at both ends of the tube 2. Inside the enlarged portion 5, 3 and the lead wire 4 are connected to each other through the crimping terminal 6. [ Further, a heat-shrinkable tube 7 having an insulating structure is coupled to the outer surface of the compression terminal 6, and a silicone tube 8 having an airtight structure is sandwiched between the inner surface of the expanded portion 5 and the outer surface. The outer surface of the extension portion 5 is tightened by a caulking operation so that the inner silicon tube 8 is tightened to maintain rigid connection and airtightness.

Therefore, a portion of the insulating filler 22 filled at both ends of the outer pipe 20 is removed through the method of spraying the sand to the cut ends of the outer pipe 20.

In addition, the exterior pipe 20 having undergone the excavating step S180 proceeds to a heat treatment step (S190) for heating the outer peripheral surface to a high temperature.

The heat treatment step (S190) is to heat the outer circumferential surface of the outer pipe (20) through the excavation step (S180) to a high temperature so that the service life of the product can be maintained even at a high temperature for a long time.

Thereafter, a bending step S200 of bending the heat-treated outer pipe 20 into a desired shape is performed. That is, the exterior pipe 20 having a rod shape of a length is bent in a zigzag shape to bend the exterior pipe 20 into a desired shape.

Thereafter, a sealing step S210 is performed in which the insulating filler 22, which is filled at both ends of the exterior pipe 20, is removed through excavation step S180, using an epoxy resin or glass.

That is, both ends of the outer pipe 20 form an insulating structure, and at the same time, both ends of the outer pipe 20 are sealed with silicon or glass to prevent the infiltration of the outside air into the inside.

Thereafter, a compression step (S220) for pressing the bent portion of the outer pipe 20 is performed. In other words, the bent portion of the outer pipe 20 is normally stretched, and a gap is formed between the inner magnesium oxide particles, which may cause a withstanding voltage.
