Title:
OVERHEAD TRANSMISSION CABLE
Document Type and Number:
Japanese Patent JP3185349
Kind Code:
B2
Abstract:

PURPOSE: To improve bending fatigue strength and plastic deformation at the time of twisting by enabling reduction in the weight and increase in the capacity without degrading tensile strength.
CONSTITUTION: A long fiber complex layer 14 for which aluminum or an aluminum alloy (hereinafter referred to as 'aluminum 12') and a long fiber 13A are compounded together is provided in the center part, and a short fiber complex layer 16 for which the aluminum 12 and a short fiber 13B are compounded together is provided on the outer periphery of the complex layer 14, while an outermost layer 17 of an aluminum 12 single body is provided on the outer periphery of the complex layer 16 to form a complex wire 11, which forms a part or the whole part of a conductor, and an overhead transmission cable is thus formed. For the long fiber 13A, a fiber of the length corresponding to at least one diameter is used, and for the short fiber 13B, a fiber of the length of no thicker than the short fiber complex layer is preferred. The cross section of the outermost layer 17 is molded by a roller die.
