Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] Such as figure 1 As shown, the present invention includes a protective cover 1, three power cores 2, four control cores 3, four ground cores 4 and a high-strength fiber 5, and the high-strength fiber 5 is located in the center of the protective cover 1 .
[0029] The control wire core 3 is composed of a conductor 31 and a high-elastic rubber insulating layer 32 wrapped outside it and a heat-resistant thin slip belt layer 33. The high-elastic rubber insulating layer 32 is located between the conductor 31 and the heat-resistant thin slip belt layer. Between 33. The four control wire cores 3 are twisted together in the same direction and wrapped in a layer of heat-resistant thin slip tape 34 to form a control cable. The outer surfaces of the control wire cores 3 are all heat-resistant thin slipping tape layers 33, and the four control wire cores 3 are wrapped in...
