Our company can manufacture and supply grain-oriented silicon iron wound toroidal cores, 0,05 to 0,30 mm thick, in size to customers’ specifications. These toroidal cores can be supplied with the following finishing: In order to meet the requirements of a magnetic circuit, we suggest to use where is possible, the following ratio: d D h 14 – 15 – 16 – 17 – 18 – 19 – 20 – 21- 22 – 24 – 25 – 26 – 28 – 29 – 30 – 31 – 33 – 35 – 36 – 37 – 38 – 39 – 40 – 42 – 43 – 44 – 45 – 46 – 48 – 50 – 52 – 53 – 54 – 55 – 56 – 57 – 58 – 60 – 61 – 64 – 65 – 66 – 68 – 70 – 72 – 74 – 76 – 78 – 79 – 80 – 85 – 87 – 88 – 90 – 92 – 95 – 100 – 110 – 120 -125 – 140 – 150 – 155 – 270 – 365 – 375 Min. 25 10 – 13 – 15 – 18 – 19 – 20 – 22 – 25 – 28 – 30 – 32 – 35 – 38 – 40 – 45 – 50 – 60 – 70 – 75 – 80 – 85 – 90 – 95 – 100 – 105 – 110 – 115 – 120 – 125 – 130 – 135 – 140 – 145 – 150 – 155 – 160 – 165 – 170 – 175 – 180 – 185 – 190 – 195 -200 Expoxy resin covered for power transformers
