Abstract
The invention discloses a crosslinked polyethylene steel strip armored halogen-free low-smoke flame retardant power cable, which comprises a polyvinyl chloride outer sheath layer, wherein insulating cores, a filling layer, a lapped tape, a liner and a steel strip armor layer are coated inside the polyvinyl chloride outer sheath layer; the filling layer and the lapped tape are made of halogen-free flame retardant materials; the liner is made of the halogen-free flame retardant material; steel wires are armored outside the liner to form a steel wire armor layer; a polyvinyl chloride outer sheath is extruded outside the steel wire armor layer to form the polyvinyl chloride outer sheath layer; a conductor shielding layer and an insulating shielding layer are made of semiconductive materials; and the conductor is a single-strand or multi-strand copper conductor. The power cable has halogen-free low-smoke flame retardancy, the combustion can be limited in a local range and can be prevented from spreading, and higher loss is avoided.
Description
Technical field
The present invention relates to a kind of power cable with cross-linked polyethylene insulation, especially have the power cable of LSOH anti-flaming characteristic.
Background technology
In recent years; In the electric power system fire incident in the global range, cause the ratio of power system power supply interruption on the rise owing to power cable catches fire, common cable is not owing to possess the function of fire protection flame retarding; Reach easy being burnt and cause power failure; Cable can produce a large amount of pernicious gases in burning, the harm Field Force's is healthy and safe, therefore has in a large number in power plant, transformer station etc.
ElectricEquipment and the intensive place of laying a large amount of cables adopt flame retardant cable to stop fire spreading, seem very necessary.
Summary of the invention
The problem that the present invention will solve provides a kind of crosslinked polyethylene steel-tape armouring zero-halogen low-smoke flame-retardant electrical cable that can stop the cable fire spreading and can not produce pernicious gas; This cable can stop the cable fire spreading to avoid the quilt of other electric equipments to burn effectively, has guaranteed first field device and personnel's safety.
In order to address the above problem, the present invention realizes through following technical scheme, a kind of crosslinked polyethylene steel-tape armouring of the present invention zero-halogen low-smoke flame-retardant electrical cable; Comprise the polyvinyl chloride external sheath layer, in the polyvinyl chloride oversheath, be surrounded by insulated wire cores, packed layer; Band, liner and steel-tape armouring layer.
Further improvement of the present invention is: packed layer and band adopt is the fire proofing of Halogen not, at the peripheral coiling band of insulated wire cores and packed layer.
Further improvement of the present invention is: liner adopts the not fire proofing of Halogen, makes with the form that extrudes, and at the armoured steel wire of liner, forms the wire armoring layer, outside the wire armoring layer, extrudes the polyvinyl chloride oversheath, forms the polyvinyl chloride external sheath layer.
Further improvement of the present invention is: insulated wire cores comprises conductor, conductor shield, insulating barrier, insulation screen, metal screen layer, restrictive coating.
Further improvement of the present invention is: conductor shield and insulation screen are made by semiconductive material, and insulating barrier is the LSOH anti-flaming cross-linking polyethylene materials.
Further improvement of the present invention is: conductor is sub-thread or multiply copper conductor.
Compared with prior art, the material that the present invention uses is the LSOH anti-flaming material, can stop the expansion of the intensity of a fire to be stretched effectively.
Description of drawings
As shown in the figure: Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of single insulated wire cores among Fig. 1.
The figure acceptance of the bid, 1 insulated wire cores, 2 packed layers, 3 bands, 4 liners, 5 steel-tape armouring layers, 6 polyvinyl chloride external sheath layers, 7 conductors, 8 conductor shields, 9 insulating barriers, 10 insulation screens, 11 metal screen layers, 12 restrictive coatings.
Embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is done below and further describe, this embodiment only is used to explain the present invention, protection range of the present invention is not constituted to limit.
Like Fig. 1, shown in Figure 2, a kind of crosslinked polyethylene steel-tape armouring of the present invention zero-halogen low-smoke flame-retardant electrical cable comprises polyvinyl chloride external sheath layer 6, in said polyvinyl chloride external sheath layer 6, is surrounded by insulated wire cores 1; Packed layer 2, band 3, liner 4 and steel-tape armouring layer 5 are at the peripheral coiling band 3 of said insulated wire cores 1 with packed layer 2; Said packed layer 2 and band 3 adopt is the fire proofing of Halogen not, and said liner 4 also adopts the not fire proofing of Halogen, with extruding the form making, in order to increase the intensity of cable; At liner 4 armoured steel wires, form wire armoring layer 5, outside wire armoring layer 5, extrude the polyvinyl chloride oversheath, form polyvinyl chloride external sheath layer 6; Said insulated wire cores comprises conductor 7, conductor shield 8, insulating barrier 9; Insulation screen 10, metal screen layer 11 and restrictive coating 12; Insulating barrier 9 is the LSOH anti-flaming cross-linking polyethylene materials, and conductor 7 is sub-thread or multiply copper conductor, and conductor shield 8 is to be made by semiconductive material with insulation screen 10.
The present invention makes cable possess the LSOH anti-flaming characteristic through said structure,, can be limited in burning in the subrange just in case catch fire when cable, does not produce and spreads, and keeps other various device, avoids resulting in greater loss.
