Abstract
The utility model discloses a kind of two core cross linked insulation fireproof power cables, comprise cable core, this cable core forms by two semicircle insulated wire cores are stranded; Cable core outer cladding fire-resistant wrapping tape layer, fire-resistant wrapping tape layer weaves armour outward, and outermost extrudes oversheath; Described semicircle insulated wire cores is made up of semicircular conductor and the semi-circular insulating layer be extruded in outside conductor.The utility model uses ultraviolet light cross-linking material to produce, and has excellent electric property, and transmission capacity is large, long service life, Long-term service temperature is at 125 DEG C, and common crosslinked cable at 90 DEG C, thus can only can reduce production cost, improves the quality of products, enhance productivity, environmental protection, nontoxic; This cable improves fire resistance structure, and not only processing technology is simple, cost-saving, and greatly strengthens fireproofing of cable.In addition, the cable core structure that this cable adopts, does not need to be provided with packed layer, has saved cost; Conductor adopts aluminium conductor, also saves cost.
Description
Technical field
The utility model belongs to power cable field, is specifically related to a kind of two core cross linked insulation fireproof power cables.
Background technology
The manufacture craft of crosslinked cable generally includes following steps: appear for the first time, carry out the strand operation of conductor, next the wrapped semiconductive band of conductor will made, to form semiconductive lapping layer, carry out insulation operation afterwards, in insulation operation, need to say that the conductor being coated with semiconductive band draws into head, extrude into internal shield, insulating barrier and outer shielding layer, carry out subsequent handling after insulation operation, form buffering water blocking layer, metallic sheath, anticorrosive coat and oversheath.
At present, existing crosslinked cable is divided into warm water crosslinking and cross-linking radiation two kinds, and structure mostly is crosslinked polyetylene insulated, copper conductor and oversheath are formed.
And the deficiencies in the prior art part is: existing cable crosslinked insulating material, when adopting warm water crosslinking, it is difficult that the factor due to people causes the cable material degree of cross linking to control; When adopting cross-linking radiation, though to a certain degree improve and improve, stabilize the problem of the degree of cross linking, power consumption is large; In addition, prior art conductor great majority all adopt copper conductor, China's copper resource shortage.
Utility model content
The purpose of this utility model is to provide and a kind ofly can improves and also can reduce by two core cross linked insulation power cables of energy consumption while stablizing degree of cross linking problem, this cable improves fire resistance structure, not only processing technology is simple, cost-saving, and greatly strengthens fireproofing of cable.
A kind of two core cross linked insulation fireproof power cables described in the utility model, comprise cable core, and this cable core forms by two semicircle insulated wire cores are stranded; Cable core outer cladding fire-resistant wrapping tape layer, fire-resistant wrapping tape layer weaves armour outward, and outermost extrudes oversheath; Described semicircle insulated wire cores is made up of semicircular conductor and the semi-circular insulating layer be extruded in outside conductor.
Further improvement, described semicircular conductor is aluminium conductor.
Further improvement, described semi-circular insulating layer adopts a kind of ultraviolet light cross-linking material.
Further improvement, described armour is steel band.
Further improvement, described outer jacket is low-smoke halogen-free polyolefin fire retardant jacket.
The beneficial effects of the utility model are:
The utility model uses ultraviolet light cross-linking material to produce, and has excellent electric property, and transmission capacity is large, long service life, Long-term service temperature is at 125 DEG C, and common crosslinked cable at 90 DEG C, thus can only can reduce production cost, improves the quality of products, enhance productivity, environmental protection, nontoxic; This cable improves fire resistance structure, and not only processing technology is simple, cost-saving, and greatly strengthens fireproofing of cable.In addition, the cable core structure that this cable adopts, does not need to be provided with packed layer, has saved cost; Conductor adopts aluminium conductor, also saves cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of two core cross linked insulation fireproof power cables described in the utility model, comprise cable core, and this cable core forms by two semicircle insulated wire cores are stranded; Cable core outer cladding fire-resistant wrapping tape layer 3, fire-resistant wrapping tape layer 3 outer braiding armour 4, outermost extrudes oversheath 5; Described semicircle insulated wire cores is made up of semicircular conductor 1 and the semi-circular insulating layer 2 be extruded in outside conductor 1.
Described semicircular conductor 1 is aluminium conductor; Described semi-circular insulating layer 2 adopts a kind of ultraviolet light cross-linking material; Described armour 4 is steel band.Described outer jacket 5 is low-smoke halogen-free polyolefin fire retardant jacket.
The utility model provides a kind of two core cross linked insulation fireproof power cables; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
