/cm2 or less of air or nitrogen gas is sealed,
It is necessary to keep the inside airtight to prevent gas leakage from the connection. For this reason, conventionally, in constructing the connection portion of the cable, the Urasuke lead pipe construction method using heat, the GS cable construction method, or purely mechanically, the airtight construction method using sealing tape, etc., have been used.

劣り、長期間を経ると、接続部の気密性が劣化してガス
漏れを生じるなど、信頼性に欠けろという欠点があった
。However, the cable connections using these conventional airtight construction methods are complicated and require heat.
It is difficult to work because it requires wrapping multiple layers of highly adhesive sealing tape, and it requires skill to perform these tasks, making it difficult to always obtain uniform airtightness. Ta. For this reason, to compensate for these drawbacks of the conventional method, there are methods that use non-adhesive rubber backing, but this method has poor adhesion to the external waves of the cable, and over a long period of time, the airtightness of the connection part may deteriorate. However, there were drawbacks such as a lack of reliability, such as deterioration of the gas and gas leaks.
