what’s Seal design protection of China PV connector

 China PV connector seal design can effectively block the long-term moisture, atmospheric pollutants and other contaminants into the system impact or corrosion of metal conductors or connectors to ensure high reliability connectors. Sealing requirements can achieve the following options:

(1) the use of box sealing structure design, the use of rubber gaskets or O-ring seal. However, the temperature inside and outside the box in order to ensure a balance should increase ventilation cooling holes, and heat ventilation holes must ensure that dust and water requirements. The design of the way higher, the structure is relatively complex and costly. But easy to use and quick.

(2) The sealing material isolation seal, that all exposed metal conductors or connectors on the sealing isolation layer thick coating layer, such as epoxy, silicone and other sealing materials. The way the design requirements low, the structure is relatively simple and low cost. However, the performance of coating materials have high requirements, such as metallic conductors or connected with the terminals of the thermal expansion coefficient matching, viscosity requirements, dielectric strength requirements, heat resistance, stability, life cycle and so these have to be considered.
