Description

Protected type fire protection flame retarding solar photovoltaic cable
Technical field
The utility model is related to photovoltaic cable technical field, specially protected type fire protection flame retarding solar photovoltaic cable.
Background technology
Cable is typically by several or the stranded similar rope cable of several groups of wires (every group at least two), and every group is led Mutually insulated between line, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation.Cable has interior 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.
