Power Partners - Three-Phase Triplex Specifications Sheet

Power Partners Inc.Athens, GAISO 9001 CertifiedPDL 46-202Page 1Three Phase Triplex Overhead Distribution Transformer2009 The Power Partners, Inc. Triplex overhead distribution transformer can be used to serve three phase applications through 225 kVA. Triplex designs consist of three separate single-phase core-coil assemblies in one tank.Triplex overhead distribution transformers are often used to serve large motor loads where the motors are frequently started. Oil field pumping loads and some irrigation pumping loads should use only triplex designs. Also, the Triplex trans-former has international applications where Dy 5 and Dy 11 phase displacement are required.Ratings• 30-225 kVA• 65°C rise• 60 Hertz standard, 50 Hertz optional• High Voltages: 13800 and below• Low Voltages: 208Y/120, 240 x 480, and 480Y/277• Transformer BIL RatingsTransformer Primary Transformer BIL 2400 60 kV 4160 60 kV 7200 75 kV 8320 75 kV 12000 95 kV 12470 95 kV 13200 95 kV 13800 95 kVAdvantages• Easier, cleaner installations are provided by three phase overhead transformers compared to three single-phase units.• Reduced installation costs, lower operating costs, safer operation, minimized service disruptions, and increased transformer life provided by an optional CSP protection package.• The capability to serve large motor loads requiring frequent motor starting is provided by triplex designs.• The same design, manufacturing and performance advantages that are provided on PPI single phase overhead distribution transformers are incorpo-rated into the triplex design.Features1) Wound core with step-lap joints for increased efficiency and lower noise levels.2) Progressively wound coils with adhesive resins on insulating paper or conduc-tors for increased short-circuit strength, efficiency and thermal strength.3) CSP protection package available as an option for increased protection against surge currents, short circuits and overloads:• Primary protective links • Surge arresters• Secondary circuit breaker• Secondary breaker operating handle with emergency overload reset and overload signal light.4) Three point core-coil bracing for i ncreased mechanical strength.5) Self-venting and resealing cover that eliminates the need for an auxil-iary pressure relief device and offers increased safety through higher tank withstand.6) The paint finish process applies a durable, corrosion resistant finish to the product. The finish meets or exceeds all the performance requirements of ANSI C57.12.28. The multi-step process includes an epoxy primer uniformly applied by cationic electro-deposition and a urethane top coat.7) Cover has 13 mils minimum of polyester coating providing 15 kV dielectric insulation of tank ground parts from live parts and increasing resistance to corrosion. The cover is sloped 15° preventing water from collecting, thereby reducing the chances of corrosion and leaking.8) Tank bottom rim is three layers thick for increased durability and resistance to shipping and handling damage.Power Partners Inc.Athens, GAISO 9001 Certified2009Standard Design Dimensions and Weights (All weights and dimensions are approximate.)HV > 5000 HV < 5000BCBCA ADDOverall weights and dimensions are given in pounds, inches or gallons and are approximatesA = Overall Height, B = Overall Width, C = Overall Depth, D = Tank Diameter, E = Hanger SpacingHigh Voltages 4160GY/2400, 7200GY/4160, 8320GY/4800KVA A B C D E* Wgt Ship Wgt OIL Qty30 53 26 25 17.5 11.25 760 805 4045 57 26 25 17.5 23.25 915 960 4575 61 33 28 20 23.25 1120 1165 60112.5 61 34 28 20 36 1540 1585 58150 73 35 30 22 36 2455 2525 90225 76 35 30 22 36 2650 2745 90High Voltages 12470GY/7200, 14400GY/8320KVA A B C D E* Wgt Ship Wgt OIL Qty30 58 23 25 17.5 11.25 760 805 4045 62 23 25 17.5 23.25 920 965 4575 66 29 28 20 23.25 1310 1355 60112.5 66 34 28 20 36 1540 1585 58150 78 31 30 22 36 2470 2540 90225 81 31 30 22 36 2650 2745 90High Voltages 20780GY/12000, 21590GY/12470, 22860/GY13200, 23900GY/13800KVA A B C D E* Wgt Ship Wgt OIL Qty30 65 23 25 17.5 11.25 940 985 4545 68 26 28 20 23.25 1290 1340 6075 68 26 28 20 23.25 1340 1365 58112.5 68 34 28 20 36 1540 1585 58150 80 31 30 22 36 2470 2540 90225 83 31 30 22 36 2650 2745 90*E is the distance between the hanger brackets.
