The usage environment of photovoltaic cables

Photovoltaic cable is mainly used for outdoor environment work, photovoltaic cable can be used to connect the photovoltaic system equipment and the building electricity equipment, from the use of the environment on the performance requirements of the cable, photovoltaic cable needs to meet three requirements:

1, flame retardant

2, should have the characteristics of anti-ultraviolet aging, moisture resistance and high and low temperature resistance　

3、Anti-thermal oxygen aging

In addition, it can also be added to the previous only for some special electrical equipment with cables only require oil resistance, acid and alkali resistance and ozone resistance and other aspects of performance, this complexity, is rarely encountered in the past all types of cables.

The complexity of photovoltaic cables is also reflected in the following requirements: the products are used in ambient temperatures ranging from -40°C to +90°C, the conductor's long-term operating temperature is 120°C, the operating temperature does not exceed 120°C within 5 seconds of a short circuit, and the service life is not less than 25 years.
