The utility model discloses a super gentle symmetrical radio frequency coaxial composite cable, including pair twist radio frequency sinle silk, pair twist radio frequency sinle silk periphery is equipped with three and is the article font and distributes and to have the data sinle silk, two adjacent radicals still are equipped with the power cord between according to the sinle silk, pair twist radio frequency sinle silk, the data sinle silk, the power cord constitutes the cable core through extrusion molding in nanometer EP rubbers protective layer, the cable core outward in proper order the cladding have the combined braided shielding layer, low -density polypropylene physical blowing layer, asphalt corrosion resistant layer, the high temperature resistant weaving layer of ceramic fibre silk warp resistance, thermoplasticity environment friendly non halogen hangs down cigarette flame -retardant ethylene -propylene rubber oversheath layer. The utility model discloses being integrated into a cable with pair twist radio frequency sinle silk, data sinle silk, the power cord of several kinds of functions, so not only having reduced to lay the space, also lighten whole weight simultaneously, simultaneously, compact structure reduces to lay the space, lightens cable core weight, and the communication steady quality is reliable.
