transformers located indoors transformer heat will permit the highest absorp tion of heat from the direct rays of the sun. The (smooth tanks painted black and aluminum, coefficients of absorption of solar radiation are room temperature 26 EC) as follows: Top oil rise Max. tank DEVELOPMENT OF POLE-MOUNTED DISTRIBUTION transformer volume would be very limited because of relatively small share of those components in total volume of transformer (only 12% as per Table 3). They could play more important role in weight reduction. Weight of tank is directly linked with volume of oil. So, reduction of oil volume is the key for reduction of weight and dimensions.
