Abstract
The utility model relates to the field of cables, in particular to a cross-linked polyethylene combined insulating fire-resistant power cable with copper-clad aluminum cores and mica tapes, which consists of the copper-clad aluminum cores, fire-resistant mica tapes, polyethylene insulating layers, a waterproof filling layer, an inflaming-retarding wrapping belt and a protecting jacket. The fire-resistant mica tapes are tightly attached on the copper-clad aluminum cores; the polyethylene insulating layers are arranged outside the fire-resistant mica tapes; the waterproof filling layer is arranged between the polyethylene insulating layers and the inflaming-retarding wrapping belt; and the protecting jacket of the cable is positioned at an outermost layer. The power cable has a scientific design structure, accords with the technical requirements of a transmission cable used under a special condition, and has the characteristics of fire resistance, water proofing, moisture proofing and the like. The power cable adopts copper-clad aluminum as a cable core, and has the characteristics of low cost, safety in operation, super convenience in use, and the like.
Description
Technical field
The utility model relates to field of cables, concretely, relates to a kind of copper-covered aluminum-core mica tape crosslinked polyethylene combined insulation fireproof power cable.
Background technology
Power cable is a kind of cable that is used to transmit and distribute electric energy.Be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross river, the places such as submarine transmission line in sea excessively.In power circuit, the shared proportion of cable increases just gradually.Power cable be master in electric power system in circuit in order to transmission with distribute the cable product of high-power electric energy, comprising 1-500kV and above various electric pressure, the power cable of various insulation.Since power cable generally be embedded in the soil or be laid in indoor, raceway groove, in the tunnel, it is little to have between line an insulation distance, without shaft tower, take up an area of and lack, be subjected to weather conditions and surrounding environment influence little, transmission performance is stable, and therefore the reliability advantages of higher is used widely.But present power cable adopts copper as core more, and cost is higher, and the fire resistance of power cable is not fine at present.
Summary of the invention
In view of the prior art defective, the purpose of this utility model is to provide a kind of copper-covered aluminum-core mica tape crosslinked polyethylene combined insulation fireproof power cable.
The utility model is made of copper cover aluminum core, fire-resistant isinglass belt, polyethylene layer, the packed layer that blocks water, fire-retardant band, sheath; Fire-resistant isinglass belt is close to the copper cover aluminum core, is polyethylene layer outside fire-resistant isinglass belt, is the packed layer that blocks water between polyethylene layer and the fire-retardant band, and the sheath of cable is at outermost layer.
After adopting such scheme, compare with existing cable and the utlity model has following beneficial effect:
1, the utility model project organization science meets under the specific condition specification requirement of the transmission cable that uses, and has fire-resistant, waterproof, protection against the tide, etc. characteristics.
Characteristics such as 2, the utility model adopts that copper cover aluminum does that core is with low cost, handling safety, use are very convenient.
Description of drawings
Fig. 1 is a kind of structural representation sketch of copper-covered aluminum-core mica tape crosslinked polyethylene combined insulation fireproof power cable.
Reference numeral shown in Figure 1 is as follows: copper cover aluminum core 1, fire-resistant isinglass belt 2, polyethylene layer 3, the packed layer 4 that blocks water, fire-retardant band 5, sheath 6.
Embodiment
The utility model is made of copper cover aluminum core 1, fire-resistant isinglass belt 2, polyethylene layer 3, the packed layer 4 that blocks water, fire-retardant band 5, sheath 6; Fire-resistant isinglass belt 2 is close to copper cover aluminum core 1, is polyethylene layer 3 outside fire-resistant isinglass belt 2, is the packed layer 4 that blocks water between polyethylene layer 3 and the fire-retardant band 5, and the sheath 6 of cable is at outermost layer.
Claims (1)
