So what damage will thunderstorms cause to photovoltaic power generation equipment?1. Thunderstorms can cause damage to solar cell modules.Solar photovoltaic panels are not only the core part of photovoltaic power generation equipment, but also the most valuable part of photovoltaic power generation...

At present, the most effective and widespread method among the existing measures is to connect the metal parts of electrical equipment to the earth. The four parts of grounding equipment, grounding body, lead-in wire and earth make up the grounding system. Good grounding is the most critical step in...

Photovoltaic cables are constantly exposed to sunlight, and solar systems are often used under harsh environmental conditions, such as high temperatures and ultraviolet radiation. In Europe, sunny days will result in on-site temperatures of up to 100C for solar systems. At present, we can use a vari...

The cable can be a single-core sheathed structure (DC cable) or a multi-core sheathed structure (2~5 cores, AC cable). #solar cable#Structural Requirements:Conductor: The conductor material is annealed soft copper wire, which can be tinned or not. The conductor surface should be smooth, free of oil,...

According to EN 60216-1, EN60216-2 Arrhenius curve, temperature index is 120℃. Time 5000 h. Retention rate of breaking elongation of insulation and sheath: 50%. Then the bending test was carried out at room temperature. The diameter of the test rod should be 2 times of the outer diameter of the cabl...

Everyone must know that solar photovoltaic cables will inevitably have safety failures during use. From an objective point of view, the cost of cables is not low. If the cables are directly replaced, the cost is relatively high. Therefore, when the cables fail, The priority solution is to repair the...

Reduce failures caused by solar cable laying worksThe laying and construction of photovoltaic cables is an extremely important project. In order to ensure its normal operation, if failures occur from time to time, the possibility of problems must be eliminated during laying, and the premise of elimi...
