It is powered, the feature of external insulation.
With developing rapidly for heliotechnics, this also brings new opportunity to our photovoltaic cable, for photovoltaic
For cable, solar powered cable, which is substantially all, to be an exposure among air, is so just easily caused cable and is exposed to the sun,
Traditional photovoltaic cable service life is short, and considers insufficient in overall shielding and fire protection design.
Utility model content
For problem above, the utility model provides protected type fire protection flame retarding solar photovoltaic cable, and service life is long,
Overall reasonable in design, can meet it is solar powered during power Transmission, and shielding and fire protecting performance protrude, can
The problem of effectively to solve in background technology.
To achieve the above object, the utility model provides following technical scheme：Protected type fire protection flame retarding solar photovoltaic
Pass through polyethylene layer, glass layer, silastic-layer, screen layer and pottery from outside to inside successively in cable, including shell, the shell
Porcelain fibrous layer is filled, and being fixedly arranged in the middle of on the outside of three cable cores, three cable cores in the shell is wrapped up by silica gel sheath, three
Cable core is circular and three is in triangular shape distribution, be spaced on the outside of the shell it is outstanding be formed with multiple projections,
Multiple grooves to be formed that cave inward are provided with the projection.
As a kind of preferred technical scheme of the utility model, the screen layer passes through copper cash and multiple copper band winding groups
Into, between multiple copper bands be spaced set.
As a kind of preferred technical scheme of the utility model, multiple through holes, institute are evenly arranged among the screen layer
State through hole oval.
It is used as a kind of preferred technical scheme of the utility model, the polyethylene layer, glass layer, silastic-layer and pottery
The thickness of porcelain fibrous layer is consistent, and the shielding thickness is twice of polyethylene layer thickness.
Compared with prior art, the beneficial effects of the utility model are：
Service life is long, overall reasonable in design, can meet it is solar powered during power Transmission, Er Qieping
Cover and protruded with fire protecting performance, polyethylene layer, glass layer, silastic-layer, screen layer and ceramics are passed sequentially through in shell fine
Layer filling is tieed up, polyethylene layer possesses with excellent resistance to low temperature, moreover it is possible to which the erosion of resistance to most of soda acids, electrical insulating property is excellent
Good, glass layer and ceramic fiber layer all have good fire resistance, both can cable risen during power Transmission
To fireproof flame-retardant effect, silastic-layer heat resistance is protruded, at 180 DEG C can long-term work, a little higher than 200 DEG C can also bear number
Week and still flexible for a long time, more than 300 DEG C of high temperature is instantaneously resistant to, such design is to ensure that cable in high-temperature condition
Under still normal work, then good shielding action is played to cable by screen layer, the higher electromagnetic field of extraneous frequency exists
During through screen layer, vortex can be produced and lost.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Fig. 1 to Fig. 3 is referred to, the utility model provides a kind of technical scheme：Protected type fire protection flame retarding solar photovoltaic
Pass through polyethylene layer 2, glass layer 3, silastic-layer 4, the and of screen layer 5 in cable, including shell 1, shell 1 from outside to inside successively
Ceramic fiber layer 7 is filled, and is fixedly arranged in the middle of three cable cores 8 in shell 1, three outsides of cable core 8 are wrapped up by silica gel sheath 13,
Three cable cores 8 are circular and three is in triangular shape distribution, are spaced on the outside of shell 1 and are outstanding formed with multiple projections
Multiple grooves 12 to be formed that cave inward are provided with 11, raised 11, wearability is good, is also risen in the transportation of whole cable
To anti-skidding effect, screen layer 5 is wound by copper cash 10 and multiple copper bands 9 and constituted, and is spaced set, screen between multiple copper bands 9
