Analysis: (1) According to Table 1, the conductor and agreement.
(2) It can be seen from Table 1 that the insulation and sheath of ordinary cables are different from photovoltaic cables.
(3) Ordinary cables are only suitable for laying in ordinary environment.
(4) PV Advantages: high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV protection, flame retardancy, environmental protection, photovoltaic It is mainly used in harsh climate with a service life of more than 25 years.
