Background technology
Cable is typically by several or the cable of similar rope made of several groups of wire strandings, and cable is usually by conductor wire
Core, insulating layer, sealing sheath and four part of protection coating composition.The application of cable is wide, can be divided by its purposes：Electric power
Cable, communication cable and control cable etc..And with the increasingly depleted of traditional energy, solar energy source has become the master in China's future
Lead new energy, and solar energy source have the advantages that it is inexhaustible.
But the photovoltaic cable due to being used in photovoltaic system usually needs to use in harsh environments, as high temperature,
Ultraviolet radiation, ozone, dramatic temperature variation and chemical erosion etc., so requiring the technology of photovoltaic cable also higher.And
Using low-grade material under these environmental stress, such as cable cover(ing) insufficient strength, it will keep cable insulation seriously damaged, from
And the service life of entire cable is influenced, increase the cable system even loss of photovoltaic system, or lead to short circuit, fire and people
The appearance for the problems such as member's injury is dangerous.Therefore, it is necessary using special photovoltaic cable in photovoltaic system.For this
Phenomenon, it is entitled " photovoltaic cable " such as patent ZL201020049564.1, the technical solution which uses for：Including leading
Body, anaerobic electrician round copper rod circular copper wire made of continuous annealing Medium drawing mach ine pass through buncher beam through tin plating tin plating round copper wire
It is twisted into wrapped polyester film band outside the conductor of 22-25 times of spacing, is 120 ° of low-smoke non-halogen flame-retardant irradiation outside polyester film band
Cross-linked polyolefin insulate, and is 120 ° of low-smoke non-halogen flame-retardant cross-linking radiations outside 120 ° of low-smoke non-halogen flame-retardant irradiation crosslinked polyolefin insulatings
Polyolefin jacket；Although silicone master batch, ultra-violet absorber, antioxidant is added in the material with sheath that insulate in the photovoltaic cable
Or the substances such as fire retardant improve the high temperature resistant, uvioresistant, fire-retardant and high temperature resistance of cable, but there is also ask as follows
Topic：1, the physical preparation added in insulating layer and sheath material is uneven, can not make to have at each location point of cable
Higher high temperature resistant, uvioresistant, fire-retardant and high temperature resistance, and the insulating layer and shield that insulating layer and sheath are strip structure
Set, structural stability are poor；2, it is directly wound with polyester film outside the device conductor, though polyester film has high rub resistance, high temperature resistant
And the advantages that chemical-resistant, but the corona resistance of polyester film is insufficient；Although 3, by photovoltaic cable insulating layer and
The physical preparation of addition, improves the service life of cable in sheath, still, since photovoltaic cable use environment is more harsh,
And dosage is larger, cable also suffers from the outer force effect of stretching, compression, torsion in use, therefore, the photovoltaic cable according to
It is old to meet the requirement used in the presence of a harsh environment.
Invention content
