In order to resolve the post landing failure problem of wooden packing for conductor, insulator, transformer of REB, the names of the suitable timber species from different parts of the world, irrespective of countries of origin have been standardized along with their strength and treatability grades. The CCA treatability of some Pakistani timber species have been presented for example which was treated at high impregnation pressure with low moisture (12% MC) and low concentration (1.5% W/V) of CCA-C (chromated copper arsenate type-c, oxides) and was analyzed spectroscopically for finding out the dry oxide retentions (W/V & W/W%) of individual components of CCA-C as well as chemical balance.
