Product Description

Dry Type Transformer for Airproof Places A dry type power transformer. Dry type power transformer. Dry type transformer, also called dry type distribution transformer or dry type power transformer, is a kind of voltage transformer utilizes air cooling method to reduce its working temperature. Compared with oil immersed transformer, dry type transformer is kind of transformer whose iron core and winding are not immersed in the insulation oil. The cooling methods of dry type transformer are divided into natural air cooling (AN) and forced air cooling (AF). When in the condition of natural air cooling, dry type transformer can be operated long-term continuously under the rated capacity. When in the condition of forced air cooling, the output capacity of dry type transformer can increase by 50%. Dry type transformers are widely used in local lighting, high-rise buildings, airports, places with mechanical equipment, etc. Dry-type distribution transformer SC 10 - 30 kVA technical data Type Rated capacity (kVA) No-load loss (W) Loading loss (W/75 °C) No-Load current (%) Sound level (dB) Impedance voltage (%) Base gauge (mm) Weight (kg) Outer dimension mm (L × W × H) SC10-50/10 50 270 870 2.1 43 4 550 460 1010 × 610 × 930 SC10-80/10 80 360 1200 1.8 45 4 550 630 1010 × 610 × 960 SC10-100/10 100 400 1370 1.8 45 4 550 690 1010 × 610 × 980 SC10-160/10 160 540 1850 1.6 45 4 550 920 1180 × 880 × 1055 SCB10-200/10 200 620 2220 1.4 46 4 660 1130 1320 × 760 × 1085 SCB10-250/10 250 720 2420 1.4 46 4 660 1280 1320 × 760 × 1155 SCB10-315/10 315 890 3040 1.2 46 4 660 1390 1320 × 760 × 1155 SCB10-400/10 400 980 3500 1.2 48 4 660 1760 1380 × 760 × 1315 SCB10-500/10 500 1170 4290 1.2 48 4 660 2040 1380 × 760 × 1365 SCB10-630/10 630 1350 5160 1.0 50 4 660 2200 1420 × 760 × 1410 SCB10-630/10 630 1300 5240 1.0 50 6 660 2390 1450 × 760 × 1435 SCB10-800/10 800 1530 6100 1.0 50 6 820 2570 1600 × 970 × 1480 SCB10-1000/10 1000 1780 7150 1.0 52 6 820 3180 1600 × 970 × 1510 SCB10-1250/10 1250 2100 8530 1.0 52 6 820 3630 1720 × 970 × 1615 SCB10-1600/10 1600 2470 10300 1.0 55 6 820 4280 1720 × 1000 × 1825 SCB10-2000/10 2000 3060 12720 0.8 55 6 1070 5530 1850 × 1200 × 1715 SCB10-2500/10 2500 3600 15110 0.8 57 6 1070 6220 1920 × 1200 × 1955 SCB10-1600/10 1600 2480 11390 1.0 55 8 1070 4410 1720 × 1000 × 1825 SCB10-2000/10 2000 3060 14050 0.8 55 8 1070 5690 1850 × 1200 × 1715 SCB10-2500/10 2500 3600 16630 0.8 57 8 1070 6400 1920 × 1200 × 1955 Dry-type transformer SC(B), SG(B) 35 kV/20 kV/10 kV technical data Rate capacity (kVA) No-load loss (W) Load loss (W) Sound level (dB) Weight (kg) Dimension (mm) LV terminal No-load current (%) Impedance voltage (%) a b c d 30 220 660 40 280 600 400 650 350 25 × 3 2.0 4.0 50 310 930 42 340 600 400 705 350 25 × 3 1.5 80 420 1280 44 565 730 500 740 450 25 × 3 1.1 100 450 1460 46 610 760 500 775 450 30 × 3 1.1 125 530 1710 48 640 760 500 840 450 30 × 3 1.0 160 610 1970 50 830 1060 600 1000 550 40 × 3 0.9 200 700 2340 50 990 1070 600 1050 550 40 × 3 0.9 250 810 2550 50 1160 1120 750 1080 550 40 × 4 0.9 315 990 3210 51 1340 1120 750 1135 660 50 × 4 0.8 400 1100 3690 51 1600 1210 750 1225 660 50 × 5 0.8 500 1310 4520 53 1830 1260 750 1185 660 60 × 5 0.7 630 1460 5510 53 1870 1440 750 1180 660 60 × 6 0.6 6.0 800 1710 6430 53 2140 1470 750 1285 660 80 × 6 0.5 1000 1990 7520 55 2500 1520 900 1325 820 80 × 8 0.5 1250 2350 8960 55 2980 1640 900 1355 820 100 × 8 0.4 1600 2760 10830 55 3530 1710 900 1510 820 100 × 10 0.4 2000 3400 13360 55 4450 1820 1200 1565 1070 100 × 12 0.3 2500 4000 15880 55 5230 1920 1200 1680 1070 120 × 12 0.3 1600 2760 11970 55 3630 1800 900 1480 820 100 × 10 0.4 8.0 2000 3400 14760 55 4550 1900 1200 1540 1070 100 × 12 0.3 2500 4000 17470 55 5330 2010 1200 1650 1070 120 × 12 0.3 Working environment: Working temperature: 0 °C - 40 °C. Relative humidity: < 70%. Altitude: ≤ 2500 m. Avoid rain, moisture, high temperature, intense heat or direct sunlight. The radiating vent of the transformer and the surrounding object should be not less than 40 cm. To prevent working in the places where contains corrosive liquid, gas, dust, conductive fibers or metal chips. To prevent work in a place of vibration or electromagnetic interference. Avoid long-term upside down storage and transportation, can not be affected by a strong impact. Features: Small size, light weight, low installation cost. Low loss, low noise, obvious energy saving effect. Safety, fireproof, no pollution, can be directly run in the load center. Excellent heat dissipation performance, strong loading capacity, the operating capacity can be increased when in condition of forced air cooling. Excellent moisture resistance performance, transformer can adapt to high humidity and other harsh environments. Adopted the international advanced technology, transformer features high mechanical strength, strong ability of anti short circuit, small partial discharge, good thermal stability, high reliability and long service life. Dry type transformer can be equipped with completed temperature detection and protection system. Adopted intelligent signal temperature control system, transformer can automatically detect, display the working temperature of the three-phase winding, automatically start and stop the fan, at the same time, it can set up the function of warning, tripping and so on. Application: With excellent fireproof performance, dry type transformers are usually used for places where need fireproof and explosion-proof, such as large buildings, high-rise buildings, local lighting, airports, or places with mechanical equipment. At the same time, dry type transformer can also be installed in the center load area to reduce the voltage loss and electrical power loss.
