Abstract
Disclosed is an insulated backplane for solar photovoltaic components, which belongs to electrical insulation materials. The insulated backplane for solar photovoltaic components comprises a PET thin-film layer, a PVDF material layer and a Le film material layer; the PVDF material layer is located on the upper plane of the PET thin-film layer, and integrates with the PET thin-film layer as one body through a first gluewater layer; the Le film material layer is located on the lower plane of the PET thin-film layer, and integrates with the PET thin-film layer as one body through a second gluewater layer. The advantages of the insulated backplane for solar photovoltaic components are that the upper plane and the lower plane of the PET thin-film layer are respectively compounded with the PVDF material layer and the Le film material layer through the adhesive; the multi-layer composite structure has good weatherability and age resistance, excellent insulation performance, strong pollutant-resistance and small water vapor transmittance, and the partial discharge capacity is more than 1000V, and the service life of the product can reach more than 25 years.
Description
Technical field
The utility model belongs to the electrical apparatus insulation material, is specifically related to a kind of insulating back panel that is used for solar photovoltaic assembly.
