Abstract

The utility model relates to a novel flexible fireproof cable. The cable comprises a conductor, the conductor sets up the mineral isolation layer outward, forms the sinle silk, and is a plurality of the sinle silk sets up the isolation waterproof layer outward and forms the cable core, and is a plurality of the cable core sets up glass fiber outward around the package in-band, glass fiber sets up the thermal-insulated filling layer of mineral around the package in-band outward, the thermal-insulated filling layer of mineral establishes glass fiber outward around the package outward, glass fiber winds the package outward around the package outward and hangs the low smoke and zero halogen oversheath outward. The utility model discloses possess characteristics such as resistant bending, fire prevention temperature height, easy laying, rigidity fireproof cable can not receive the restriction of core number, and the major length production, the water barrier effectively blocks water, prevents that rigidity fireproof cable's magnesia powder from easily weing and the problem of insulation failure from appearing, has improved the stability of cable, withstand voltage level and life-span also improve by a wide margin. And the special terminal joint is not needed when the cable is laid as a conventional cable. The temperature resistant grade can reach 950-.

Description

Novel flexible fireproof cable

Technical Field

The utility model relates to a novel flexible fireproof cable belongs to cable technical field.

Background

Fireproof cable needs to have good bending resistance and good waterproof performance to prevent insulation failure because of its service environment, and current fireproof cable can not compromise various performances in the use, consequently has low in service life in the operation, can not be fine satisfies the user demand, consequently needs to improve.

SUMMERY OF THE UTILITY MODEL

To the above defect, the utility model aims to provide a novel flexible fireproof cable rational in infrastructure, possess various performance, fully provided user demand.

Therefore, the utility model adopts the technical scheme that: novel flexible fireproof cable, including conductor (1), conductor (1) is provided with mineral isolation layer (2) outward, forms the sinle silk, and is a plurality of the sinle silk sets up isolation waterproof layer (3) outward and forms the cable core, and is a plurality of the cable core is provided with glass fiber outward and is wound package (5) around the covering in-band, glass fiber is around the covering in-band and is provided with mineral thermal-insulated filling layer (6) outward, mineral thermal-insulated filling layer (6) peripheral hardware glass fiber is around package (7) outward, glass fiber is around package outward low smoke and zero halogen oversheath (8) of package (7) outward.

Further, flame-retardant filling (4) is filled between the cable cores.

Further, the conductor (1) is a tin-plated or tin-free copper conductor conforming to GB/T3956.

Further, the mineral isolation layer (2) is a ceramic silica gel material or a ceramic polyolefin material or other mineral materials.

Further, the isolation waterproof layer (3) is a PE waterproof layer.

The utility model has the advantages that: the utility model discloses possess characteristics such as resistant bending, fire prevention temperature height, easy laying, rigidity fireproof cable can not receive the restriction of core number, and the major length production, the water barrier effectively blocks water, prevents that rigidity fireproof cable's magnesia powder from easily weing and the problem of insulation failure from appearing, has improved the stability of cable, withstand voltage level and life-span also improve by a wide margin. And the special terminal joint is not needed when the cable is laid as a conventional cable. The temperature resistant grade can reach 950-.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1 conductor, 2 mineral isolation layers, 3 isolation waterproof layers, 4 flame-retardant fillings, 5 glass fiber are wrapped in a wrapping band by 6 mineral heat insulation filling layers, 7 glass fiber are wrapped outside the wrapping band by 8 low-smoke halogen-free outer sheaths.

Detailed Description

Novel flexible fireproof cable, including

conductor

1, 1 outer mineral isolation layer 2 that sets up of conductor forms the sinle silk, and is a plurality of the sinle silk sets up 3 formation cable cores of isolation waterproof layer outward, and is a plurality of set glass fiber outside the cable core is around the package in-band around package 5, glass fiber is around the package in-band around package 5 outer mineral thermal-insulated filling layer 6 of setting up, 6 outer glass fiber of mineral thermal-insulated filling layer are around package 7 outward, glass fiber is around package 7 outer low smoke and zero halogen oversheath 8 outward.

Further, flame-retardant filler 4 is filled between the cable cores.

Further, the conductor 1 is a tin-plated or tin-free copper conductor conforming to GB/T3956.

Further, the mineral isolation layer 3 is a ceramic silica gel material, a ceramic polyolefin material or other mineral materials.

Further, the isolation waterproof layer 3 is a PE waterproof layer.

The following is a further explanation of the present invention to better understand the present invention: the utility model discloses a conductor, mineral insulating layer, isolation (waterproof layer), packing, thermoplasticity separate porcelainization isolation layer, low smoke and zero halogen outer jacket.

The conductor is a tinned or non-tinned copper conductor conforming to GB/T3956.

The multi-core cable is characterized in that a plurality of layers of mineral insulating layers are coated outside the conductor, a PE waterproof layer is extruded outside the insulating layers, high-flame-retardant filling is filled in the middle of the multi-core cable, a glass fiber rope is wrapped, a mineral heat-insulating filling layer is coated outside the multi-core cable, the glass fiber rope is wrapped, and a low-smoke halogen-free outer protective layer is arranged outside the.

Wherein the mineral insulating layer adopts ceramic silica gel material or ceramic polyolefin material or other mineral materials, and this insulating layer meets fire and crust into hard ceramic insulating layer rapidly, and the inside and outside glass silk fibre of wrapping is around the band, firmly fixes the insulating layer, forms permanent effectual protection to the cable core. The cable can work stably for a long time.
