Abstract
The utility model discloses a filling strip for a three-core fire-resisting power cable, which comprises a filling strip with a fan-shaped section, and is characterized in that the surface of the filling strip is provided with bulges with an interval of 1 to 5mm and the height of 1 to 5mm; and the inner side is provided with a hollow hole with a fan-shaped section; one end of the side face of the filling strip is provided with bosses, and the other end is provided with grooves bitten with the bosses. The filling strip disclosed by the utility model is made of ceramic silicone rubber, and can turn into a ceramic hard shell when subject to certain heat, thereby having good fire-resisting performances and being nontoxic and environmentally-friendly; the cable core can be coated completely with the unique structure, good flame retardancy and heat insulation effects are provided, and impact resistance of the cable is improved.
Description
Technical field
The utility model relates to electricapparatus and equipment is made the field, relates in particular to a kind of three core fireproof power cable packings.
Background technology
In order to make the peripheral roundness of cable good, need to three cable cores in cable between the place, space add filler, and isolated cable core and external contact that traditional packing can not be complete, flame retardant effect can not reach the requirement of fire-resisting cable.Present fire-resistant packing materials'use PVC flame retardant filler strip, this packing is mainly that Halogen is fire-retardant, when breaking out of fire, can produce a large amount of smog, produce poisonous, with irritating and corrosive hydrogen halide, smog can hinder relief and evacuating personnel, hydrogen halide meeting etching apparatus, health that also can harmful to human is so just need the nontoxic cable filler strip of a kind of novel environment friendly.
The utility model content
In order to overcome defects, the utility model provides a kind of asepsis environment-protecting, good flame retardation effect and shock proof three core fireproof power cable packings.
To achieve these goals, the technical solution of the utility model is: a kind of three core fireproof power cable packings, comprise that the cross section becomes fan-shaped packing, described packing surface is provided with and is spaced apart 1～5mm, it is highly the projection of 1～5mm, it is fan-shaped hollow hole that inside is provided with the cross section, and packing side one end is provided with boss, and the other end is set up the groove with the interlock of boss phase.
Further, described packing material is ceramic silicon rubber
The beneficial effects of the utility model are: 1, this packing adopts the manufacturing of ceramic silicon rubber, can guarantee that cable is under fire hazard environment, cable heated is after uniform temperature, the performance of packing changes, form the duricrust of ceramic, thereby guarantee that cable has good fire resistance property asepsis environment-protecting simultaneously under fire hazard environment.
2, there is the projection of interval 1～5mm, height 1～5mm on the surface of this packing, utilizes the supporting role of projection, can effectively reduce the contact-making surface between the inner cable core of packing and cable and outside sheath, thereby play certain heat-insulating flame-retardant effect.
3, the covering of the fan two ends of this packing are when cable cabling, and three packings are filled in respectively in three gaps of three-core cable, can be engaged together circular; complete coating cable core; in fire hazard environment, can form good protection to cable, improve the impact resistance of cable.

Embodiment
Below in conjunction with specific embodiment, the utility model is described further.
As shown in Figure 1, three core fireproof power cable packings, comprise that the cross section becomes fan-shaped packing, described packing surface is provided with and is spaced apart 1～5mm, it is highly the projection 3 of 1～5mm, it is fan-shaped hollow hole 2 that inside is provided with the cross section, and packing side one end is provided with boss 1, and the other end is set up the groove 4 with boss 1 phase interlock.
As shown in Figure 2, packing of the present utility model is when cable cabling, and three packings are filled in respectively in three gaps of three-core cable, and boss 1 and groove 4 are engaged together circular, coating cable core that can be complete plays good anti-flaming thermal-insulation effect and the impact resistance that improves cable.
As shown in Figure 3, boss 1 and the engaged partial enlarged drawing of groove 4 between two of packings of the present utility model.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model is within all falling into protection range of the present utility model.
Claims (2)
