Power cables are cable products used in the trunk lines of electric power systems to transmit and distribute high power electric energy, including various voltage classes, 1-500KV and above, and various insulated power cables. In the process of cable laying, the joint part is the weakest link of cable in the middle of the cable, easily causes the incident, still can influence other cables with the ditch simultaneously, so the protection section of most current cable joint adopts the fire blanket to protect mostly to reduce the emergence of secondary disaster, nevertheless there is the weak point with the fire blanket for most current cables: firstly, the fire blanket for most current cables's fire-retardant ability is relatively poor, leads to the cable to be influenced by the heat life, and secondly, most current fire blankets for most cables are not equipped with adjustable tightening mechanism mostly, leads to the clearance that easily exists during the installation to influence the barrier propterty of fire blanket.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the fireproof blanket for the cable is provided for solving the problem that the cable is easy to be affected by heat and has long service life due to poor flame retardant capability of most of the existing fireproof blankets for the cable.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the fire blanket for the cable comprises a cable main body and a fire blanket main body, wherein the fire blanket main body comprises a first blending layer, a high-temperature-resistant coating, a fiber felt and a second blending layer, and the second blending layer, the fiber felt, the high-temperature-resistant coating and the first blending layer are sequentially arranged inside and outside the fire blanket main body.

As a further description of the above technical solution:

the first blending layer and the second blending layer are made of the same material.

As a further description of the above technical solution:

the outside of fire blanket main part is provided with two sets of locating parts, the spacing groove has all been seted up to the inside of two sets of locating parts, be provided with two sets of spacing mouths on the locating part, and the inside and the spacing groove of spacing mouth are linked together.

As a further description of the above technical solution:

the limiting piece is made of elastic materials.

As a further description of the above technical solution:

the surfaces of the first blending layer and the second blending layer are both provided with skin-friendly wear-resistant coatings.

As a further description of the above technical solution:

the thickness of the fireproof blanket main body is 8 mm.

As a further description of the above technical solution:

the first blending layer is made of alkali-free high-flame-retardant blending composite fiber materials.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses in, the fire blanket main part includes first blending layer, anti high temperature coating, fibrofelt and second blending layer, the inside of fire blanket main part has set gradually the second blending layer outside the lining, the fibrofelt, anti high temperature coating and first blending layer, fire-retardant effect has been realized on first blending layer, avoid influencing the use of cable main part, anti high temperature coating has realized the temperature and has cut off, heat transfer to cable main part on the first blending layer has been avoided, the fibrofelt has realized further thermal-insulated, thereby make the surface temperature of cable main part maintain in the temperature range of normal use, avoid influencing the life of cable main part, block through multistage heat, the protection to the cable main part has been realized.
