Abstract
The utility model relates to a halogen-free, refractory, shielding, anti-jamming and flexible cable used for a communication power supply, which comprises one or a plurality of conductors and leads, wherein the conductor is formed by twisting copper wires, the lead is formed by wrapping an insulating layer outside the conductor, an outer protective sleeve is arranged outside the lead, and a refractory layer is arranged between the conductor of the lead and the insulating layer; a halogen-free wrapping strip layer and a metal shielding layer are sequentially arranged between the insulating layer of one lead and the outer protective sleeve, or a halogen-free filling layer is arranged among a plurality of leads, and the halogen-free wrapping strip layer and the metal shielding layer are sequentially arranged between the halogen-free filling layer and the outer protective layer. The utility model has good flexibility, environment protection and excellent flame-retardant performance and can not spread for combustion or generate toxic gas containing halogen in case of a fire, and the shielding performance of the cable can effectively prevent external electromagnetic signals from interfering the cable.
Description
Technical field
The utility model relates to a kind of feed cable, especially the communication power supply flexible cable.
Background technology
The existing communication power supply is with flexible cable its better softness, but its environmental protection, fire resistance and shielding interference free performance still have some deficits, and can not adapt to the instructions for use of feed cable in the communications equipment room.
Summary of the invention
In order to overcome the existing communication power supply with the deficiency of flexible cable, the purpose of this utility model provide a kind of communication power supply with Halogen, fire-resistant, shield anti-interference flexible cable.
A kind of communication power supply that the utility model provides comprises a lead that is made of the outer insulating barrier that coats of the stranded conductor that forms of copper wire and conductor with Halogen, fire-resistant, the anti-interference flexible cable of shielding, lead has oversheath outward, between the conductor of lead and insulating barrier, be provided with flame retardant coating, between the insulating barrier of lead and oversheath, be provided with wrapped belt of Halogen and metal screen layer successively.
This reality has the novel another kind of communication power supply that provides to comprise several leads that are made of the outer insulating barriers that coat of the stranded conductor that forms of copper wire and conductor with Halogen, fire-resistant, the anti-interference flexible cable of shielding, several leads have oversheath outward, between the conductor of every lead and insulating barrier, be provided with flame retardant coating, between several leads, be provided with the Halogen packed layer, between Halogen packed layer and oversheath, be provided with wrapped belt of Halogen and metal screen layer successively.
The beneficial effects of the utility model are: not only flexibility is good, and environmental-protecting performance and fire resistance are good, in case run into fire, cable can propagating combustion, can not produce the Halogen toxic gas.The shielding properties of cable is excellent, can effectively prevent the interference of external electromagnetic signal to cable.
