Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of weak-current cable.
Background technology
Light current and electric power, electric consumption on lighting comparatively speaking, generally call light current transmitting signal, the electric energy that carries out information exchange.The handling object mainly information of light current, namely the transmission of information and control, be characterized in that voltage is low, electric current is little, power is little, frequency is high.
Existing power cable adopts multi-core conductor usually, in actual life, applied environment often also exists the phenomenon that many different electric wires work simultaneously, there is a lot of electric equipment in operation simultaneously, these electric equipments and electric wire inevitably cause radiation in the course of the work, and this radiation can cause the Signal transmissions of weak-current cable to be affected.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, provides a kind of tensile strength high, can avoid the novel weak-current cable of magnetic field and radio signal interference.
Technical scheme: in order to solve the problems of the technologies described above, the novel weak-current cable of one described in the utility model, it comprises conductor, conductor shield is provided with in described conductor outside, inner insulating layer is provided with in described conductor shield outside, high strength fibre layer is provided with in described inner insulating layer outside, described conductor shield and inner insulating layer double-layer coextrusion form, the Thickness Ratio of described conductor shield and inner insulating layer is 1:3, described conductor, conductor shield, inner insulating layer and high strength fibre layer composition core unit, described core unit is at least provided with two, packed layer is provided with in described core unit outside, external insulation layer is provided with in described packed layer outside, restrictive coating is provided with in described external insulation layer outside, aramid fiber bundle is provided with in described restrictive coating.
Described core unit establishes two altogether, and they be arranged in parallel, wraps up external insulation layer and restrictive coating successively two described core unit outsides, and their composition global sections are oval structure.
Described packed layer is ethylene propylene diene rubber packed layer.
Described inner insulating layer and external insulation layer are all crosslinked polyetylene insulated layer.
Eight aramid fiber bundles are evenly provided with in described restrictive coating.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure arranges rationally, adopt high strength fibre layer, the tensile strength of effective raising core unit, adopt conductor shield, and inner insulating layer, external insulation layer, effective fail safe and practicality improving entirety, antijamming capability is stronger, adopt filling polyurethane layer, fill light, filling effect is good, eight aramid fiber bundles are evenly set in restrictive coating, overall tensile strength can be improved further, this product is coordinated by each layer, operate steadily reliable, whole service life is long, realistic instructions for use.
