Abstract

A mould-proof and damp-proof power cable is characterized in that a conductor twisted by one or a plurality of tin plated coppers is adopted; a water stop tape which laps the conductor forms an inner-layer water stop tape layer; an insulating layer is extruded outside the inner-layer water stop tape layer so as to form an insulated conductor core, a single insulated conductor core is taken as a cable conductor, or a plurality of insulated conductor cores are twisted to form a cable, and a water stop rope is filled so as to form the cable conductor; and outside the cable conductor, an outer water stop tape layer and a longitudinal lapping aluminum-plastic tape layer which are formed by lapping the water stop tapes, and a mould-proof type PE outer sheath layer formed by lapping are arrangedsequentially from inside to outside. The mould-proof and damp-proof power cable has convenient production and processing and high production efficiency, and the cable has the mould-proof and damp-proof functions, thus guaranteeing operation safety.

Description

The moistureproof power cable of mildew-resistant

Technical field

The utility model relates to a kind of power cable, relates in particular to the moistureproof power cable of a kind of mildew-resistant, belongs to technical field of electric wires and cables.

Background technology

Electric wire is the auxiliary products of transmission ﹠ distribution electric energy, signal transmission or electromagnetic conversion.Because therefore the popularity in the field that each related electric equipment is used, needs electric wire to have the various complex environments of adaptation.The electric equipment products that external regulation damp-heat area uses require to have fungicidal properties.Southern china some areas also have the character of humid tropics weather at plum rain season, need electric wire to have performances such as mildew-resistant protection against the tide.

The cable that also has some special dimensions to use needs the special mildew-resistant humidity resistance of considering.The territory of use of shipboard cable is unrestricted, and all equipment all is in the very moist environment; Current used in nuclear power station IE level K3 class cable, great majority adopt the LSOH anti-flaming sheath, and superficial growth mould possibility exists.

If on the electric wire surface behind the mildew bacterium, the influence of cable is had:

1. influence product appearance, surface discolouration is cleaned the back and is left a trace in the grow mold zone; 2. influence surface insulation resistance, the possibility of electric leakage is arranged; 3. influence specific insulation; 4. serious situation reduces dielectric strength, and electrical breakdown may take place; 5. influence cable insulation or sheath material mechanical performance, quicken the degraded of macromolecular material etc.

Therefore, the electric wire in wet environment should have functions of resisting mould and damp, so just can guarantee the security of operation of electrical equipment.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of make easy to process, production efficiency is high, cost performance is high, it is radially waterproof and dampproof to have and have the moistureproof power cable of mildew-resistant of fungicidal properties.

The utility model adopts following technical scheme:

The design feature of the moistureproof power cable of the utility model mildew-resistant is to adopt single or many conductors that zinc-plated soft copper skein silk closes, wrapped waterstop forms the internal layer water blocking tape layer on conductor, the extruded insulation layer constitutes insulated wire cores outside described internal layer water blocking tape layer, with single insulated wire cores is cable core, or by the stranded stranding of many eradications edge core and fill waterproofing rope and constitute cable core; Outside cable core, what set gradually from inside to outside is to mould belt by outer water blocking tape layer, vertical alclad that wrapped waterstop forms, and the mould-proof-type PE external sheath layer that extrudes formation.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model has been taken all factors into consideration the suffered influence of cable under wet environment.Conductor has adopted tinned conductor, make its under wet environment the long-time running electric property be difficult for change, guarantee the fail safe of electrical equipment;

2, the utility model cable radially waterproof adopted vertical alclad to mould band, good water-proof effect, easy to process.Simultaneously, the plastic-aluminum band can also improve the performance and the quality of cable as the screen of cable;

3, the utility model has adopted water resistance better at external sheath layer, has the mould-proof-type PE sheath material of certain rotproofness again, cable is in for a long time is difficult for infiltration and mouldy in the wet environment, and global design is scientific and reasonable, convenient processing and manufacture.

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment

Embodiment 1 as shown in Figure 1:

Conductor 1 adopts tin annealed copper wire, be to adopt single or many conductors that zinc-plated soft copper skein silk closes, water blocking tape layer 2 in wrapped waterstop forms on conductor 1 extrudes poly-second insulating material of crosslinked with silicane or irradiation polyolefine material outside the internal layer water blocking tape layer, constitute insulated wire cores 3.Wrapped successively outer water blocking tape layer 5 and vertical alclad are moulded belt 7 outside single insulated wire cores 3, are provided with the many soft drainage threads 6 of tinned copper wire between plastic-aluminum belt 7 and outer water blocking tape layer 5.Extrude external sheath layer 8 on plastic-aluminum belt 7, external sheath layer 8 is that the mould-proof-type type PE that is added with mould inhibitors such as poplar anilide or oxazolone extrudes layer.

Embodiment 2 as shown in Figure 2:

Conductor 1 adopts tin annealed copper wire, be to adopt single or many conductors that zinc-plated soft copper skein silk closes, water blocking tape layer 2 in wrapped waterstop forms on conductor 1 extrudes poly-second insulating material of crosslinked with silicane or irradiation polyolefine material outside interior water blocking tape layer, constitute insulated wire cores 3; By a plurality of insulated wire cores 3 and an amount of waterproofing rope packed layer 4 stranded strandings, constitute cable conductor.Wrapped successively outer water blocking tape layer 5 and plastic-aluminum belt 7 outside cable core are provided with the many soft drainage threads 6 of tinned copper wire between plastic-aluminum belt 7 and outer water blocking tape layer 5.Extrude external sheath layer 8 on plastic-aluminum belt 7, external sheath layer 8 is that the mould-proof-type type PE that is added with mould inhibitors such as poplar anilide or oxazolone extrudes layer.

Claims
