The performance of Photovoltaic cable

Photovoltaic cable is mainly used for outdoor environment work, TUV photovoltaic cable can be used to connect the photovoltaic system equipment outside the building and the electrical equipment inside the building, from the use of the environment on the performance of the cable, photovoltaic cable has three requirements:

1, The requirements for cable flame retardant, usually this requirement will only be put forward for indoor cables

2. Outdoor cables should have UV aging resistance, humidity resistance and high and low temperature resistance

3, indoor and outdoor will encounter heat resistance oxygen aging requirements; In addition, it can also add the performance of oil resistance, acid and alkali resistance and ozone resistance only required for some special electrical equipment cables in the past. This complex situation is rarely encountered by all kinds of cables in the past. The complexity of photovoltaic cables is also reflected in the following requirements: the ambient temperature of the product ranges from -40℃ to +90℃, the long-term operating temperature of the conductor is 120℃, the operating temperature within 5 seconds of a short circuit is not more than 120℃, and the service life is not less than 25 years.

Performance of photovoltaic cable:

1, Corrosion resistance: conductor using tinned soft copper wire, has good corrosion resistance

2, Cold resistance: The insulation adopts cold resistance and low smoke halogen-free materials, can withstand -40℃, its cold resistance performance is good

3, High temperature resistance: the sheath adopts high temperature and low smoke halogen-free material, temperature resistance grade up to 120℃, excellent high temperature resistance performance

4, Other performance: photovoltaic cable insulation sheath after irradiation, with UV radiation, oil resistance, long life and so on.
