The choice of insulating material directly determines the quality of the connector. A good connector needs to choose a suitable insulating material. The applicability mainly depends on the requirements of the connector, such as the weather resistance, heat resistance, flame retardancy, mechanical properties, and insulation properties of the material. The selection of insulating materials for photovoltaic connectors is the result of comprehensive consideration of these characteristics. Choosing the right material can reduce the probability of the product catching fire at a higher temperature rise.

      Photovoltaic connectors account for a relatively low proportion of the cost of photovoltaic power plants, but they are key components. In the early stage of power station construction, the risk of failure caused by the connector is often ignored, but in the later stage, it will become a pain point in the operation and maintenance of the power station. Operation and maintenance costs caused by connector failures include loss of power generation revenue, spare parts costs, labor costs, and safety risks. These operation and maintenance costs will ultimately affect the return on investment of the power station. Reliable quality and photovoltaic connectors provided by suppliers with rich production and assembly experience are one of the foundations to ensure the normal and stable operation of photovoltaic power stations, and the normal operation of the power station is one of the prerequisites to ensure the maximum profit of the owner.
