Abstract
The utility model discloses a fireproof flexible cable comprising a lead. An insulating layer is coated on the surface of the lead, the insulating layer is a compact magnesium oxide powder filling layer, a shielding layer formed by weaving tinned copper wires is coated on the surface of the insulating layer, an outer sheath made of polyurethane rubber is covered on the surface of the shielding layer, and a gap is reserved between the shielding layer and the outer sheath. Compared with the prior art, the fireproof flexible cable has good fireproof performance and demagnetizing performance, resists high temperature, and is good in flexibility, wear resistance and cold resistance, and easier to bend; and the service life of the cable is prolonged effectively.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of fireproof flexible cable.
Background technology
At present, cable and optical cable have played significant role in the process of people's information transmission.Common cable resistance to elevated temperatures is poor, and fire protecting performance is poor, can't effectively stop the generation of electrical fire, has certain potential safety hazard; Common cable demagnetization poor performance can not play erasure effect under adverse circumstances; When needs were often drawn wireline operation, cable and ground often rubbed, and are easy to cause the damage of cable; Very close to each other between existing common cable layer and the layer, relatively more difficult when bending, do not have certain flexibility.
The utility model content
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of high temperature resistance, and the demagnetization performance is good, rub resistance and flexible fireproof flexible cable.
The technical solution of the utility model is: a kind of fireproof flexible cable, comprise lead, conductive line surfaces is coated with insulating barrier, described insulating barrier is closely knit magnesia powder packed layer, surface of insulating layer is coated with the screen that is formed by the tinned copper wire braiding, the screen surface coverage has the oversheath of being made by polyurethane rubber, leaves the gap between described screen and the oversheath.
The beneficial effects of the utility model are: the closely knit magnesia powder packed layer of insulating barrier, magnesium oxide material has higher conductive coefficient and anti-overload capacity, make fireproof cable can bear high-density current, and its electrical insulation capability excellence, screen is formed by the tinned copper wire braiding, screen strengthens the demagnetization performance, described oversheath is made by polyurethane rubber, this material has good flexibility, resistance to wear and cold resistance, can effectively increase the useful life of cable, leave the gap between screen and the oversheath, make and when bending, can relatively move between layer and the layer, make cable more flexible, also make cable possess certain flexibility simultaneously, bending is got up convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of fireproof flexible cable, comprise lead 1, lead 1 surface is coated with insulating barrier 2, described insulating barrier 2 is closely knit magnesia powder packed layer, magnesium oxide material has higher conductive coefficient and anti-overload capacity, make cable have certain fire-proof function, and electrical insulation capability is improved, insulating barrier 2 surfaces are coated with the screen 3 that is formed by the tinned copper wire braiding, and screen 3 can strengthen the demagnetization performance, and screen 3 surface coverage have the oversheath of being made by polyurethane rubber 5, this material has good flexibility, resistance to wear and cold resistance, can effectively increase the useful life of cable, leave gap 4 between described screen 3 and the oversheath 5, make when bending, can relatively move between layer and the layer, simultaneously also make cable possess certain flexibility, bending is got up convenient.
