Description
Technical field
The utility model relates to a kind of private cable, particularly relates to a kind of low stress crack resistence photovoltaic generating system private cable.
Background technology
Along with the development of global economy society, the scarcity of fossil energy more and more highlights, another overall background person is the fact of global warming, the disastrous effect of greenhouse gas emission manifests day by day, control the target of greenhouse gas emission, it is inadequate for depending reduction of discharging alone, has the lasting reliable renewable and clean energy resource of development only and is only the method for effecting a permanent cure, so photovoltaic generation industry has grand prospect.
Solar energy is the inexhaustible regenerative resources of the mankind, there is the advantage such as abundance and potential economy of sufficient spatter property, absolute fail safe, relative popularity, certain long-life and non-maintaining property, resource, in long-term energy strategy, there is critical role.Compared with other new forms of energy, solar energy should be real final solution route.From available total amount, water energy, wind energy, tidal energy are all too little, are not enough to meet human demand.So solar energy is known to the mankind, utilizable at present, clean and safe, the unique energy source that can solve needed for human future is selected, and photovoltaic generating system cable has wide promotion prospect.
Utility model content
The purpose of this utility model is to meet ac rated voltage 600/1000V and DC rated voltage 1800V and the transmission of following photovoltaic power generation system current is formed a complete and comprehensive system for collecting real estate fees demand, provides a kind of low stress crack resistence photovoltaic generating system private cable.
The technical solution of the utility model is: described cable comprises conductor, extrude photovoltaic cable 125 DEG C of heat curing-type halogen-free and low-smoke flame-retardant polyolefin insulating barriers outside described conductor and form insulated wire cores, described insulated wire cores extrudes photovoltaic cable 125 DEG C of heat curing-type halogen-free and low-smoke flame-retardant polyolefin waterproof sheaths, seizing wire braid, photovoltaic cable 125 DEG C of heat curing-type halogen-free and low-smoke flame-retardant polyolefin waterproof outer jacket strandings outward successively.
Described described conductor is the 1st, 2, the 5 class tinned conductors meeting GB/T3956-2008 requirement.
