PURPOSE:To use a communication cable even in higher temperature environment by interposing radiation fins between a communication cable main body and an outer shell tube. CONSTITUTION:An outer shell tube 5 composed of stainless steel e.g. SUS 304, etc., covers the circumference of a communication cable main body 1, and radiation fins 6 are interposed between the outer shell tube 5 and the communication cable main body 1. The outer shell tube 5 can be sticked fast to the radiation fins 6 by drawing through a die. The radiation fins 6 are composed of e.g. copper, etc., having good heat conductivity, formed by two in a radius direction with the communication cable main body 1 as the center, extended parallel to the center line direction of the communication cable main body 1, and retain the communication cable main body 1 in apart from the outer shell tube 5. Coolant can be flown in a space demarcated with the radiation fins 6, the communication cable main body 1, and the outer shell tube 5. This improves heat resistance. |
