Abstract
Disclosed in the utility model is a flexible cable with characteristics of polyvinyl chloride insulation and flame-retardant polyurethane elastomer sheath. The flexible cable comprises at least one group of inner cores; each of the inner cores at least includes two metal conductors; and polyvinyl chloride insulating layers are respectively arranged outside the metal conductors. A flame-retardant polyurethane elastomer inner sheath layer coats the outsides of the polyvinyl chloride insulating layers; and the space between the flame-retardant polyurethane elastomer inner sheath layer and the polyvinyl chloride insulating layers is filled with filling ropes. A steel band armored layer coats the outside of the flame-retardant polyurethane elastomer inner sheath layer and is formed by trapezoid filaments and circular filaments, wherein the trapezoid filaments and the circular filaments are in a mutually spacing encircling mode. A shielding layer is arranged outside the steel band armored layer; a current carrying conductor is arranged outside the shielding layer; and a flame-retardant polyurethane elastomer outer sheath layer is arranged outside the current carrying conductor. According to the utility model, the provided flexible cable with the advantages of high insulating reliability, good flame retardant effect, good stability, enhanced wiring-resistant performance, enhanced press resistance, and prolonged service life can be applied to an indoor area, a tunnel, a cable trench or buried laying and the like.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of polyvinyl chloride insulation, flame resistance polyurethane elastomer sheathing flexible cable.
Background technology
Development along with power industry, data communication industry, urban track traffic industry etc., all trades and professions are more and more higher to the requirement of cable, in use, will avoid not only that cable is mechanically damaged, insulation harm, ageing of insulation are rotten etc., also under hot conditions, use, namely high temperature resistant.The current capacity of cable is relevant with the sectional area of conductor thread core usually simultaneously, conductor temperature is raise, the temperature of the outer insulating barrier that coats of conductor surpasses the last change that can cause on the insulating barrier generation performance in limited time, thereby the insulating reliability of insulating barrier is reduced greatly, influence the useful life of cable.
Existing common cable exists structural stability difference and easy firing, the problem of fire protecting performance, water resistance difference, so the fire-retardant problem of the lsafety level of electric wiring and cable more and more causes people's attention; Even if cable has good heat resistance, in the higher occasion of fail safe, but can not prevent vegeto-animal destruction, also may bring big indirect loss to power supply.
