What are the functions and characteristics of outdoor photovoltaic cables?

How much do you know about Coslight photovoltaic cables?

Photovoltaic cables are mainly used in outdoor environments. TUV photovoltaic cables can be used to connect photovoltaic system equipment outside the building and electrical equipment inside the building. From the performance requirements of the cable in the use environment, the optical cable integrates three requirements.

1. For the requirements of the flame retardancy of cables, this requirement is usually only put forward for indoor cables.

2. Outdoor cables should have the requirements of UV aging resistance, moisture resistance, high and low temperature resistance, etc.

3. Indoor and outdoor heat-resistant oxygen aging requirements; in addition, you can also add oil resistance, acid and alkali resistance and ozone resistance, which is a complex situation rarely encountered by various cables in the past. The complexity of photovoltaic cables is also reflected in the following requirements: the ambient temperature of the product is -40 ℃ to +90 ℃, the long-term working temperature of the conductor is 120 ℃, the working temperature within 5 seconds of short circuit does not exceed 120 ℃, and the service life is not less than 25 years. Given the complexity of PV cables, the industry positions PV cables as another type of outdoor cable rather than normal outdoor cables.

 Advantages of outdoor  solar cable products.

1. Corrosion resistance: The conductor is made of tinned soft copper wire, which has good corrosion resistance.

2. Cold resistance: The insulation is made of cold-resistant, low-smoke, halogen-free materials, cold-resistant to -40°C, and has good cold resistance.

3. High temperature resistance: The sheath is made of high temperature, low smoke and halogen-free materials, with a temperature resistance level of up to 120 °C and excellent high temperature resistance.

4. Other properties: After being irradiated, the insulating sheath of photovoltaic cable has the characteristics of anti-ultraviolet radiation, oil resistance and long service life.

Characteristics of outdoor photovoltaic cables.

Currently commonly used TUV photovoltaic cables are environmentally friendly. It has good corrosion resistance and high temperature resistance. From the perspective of the impact of the cable on the environment, the cable belongs to the green cable. The earliest PV cables were PVC insulation and rubber jackets, which have been eliminated from the European market.
