AC WELDING TRANSFORMER

PRODUCT SPECIFICATION AND COMPOSITIONMEDIUM VOLTAGECentrado Transformer are adjusted to distribution voltage in Indonesia between 3 KV - 6 KV - 7 KV - 12 KV - 20 KV - 24 KV. Tap Changer at 2.5% - 5% - 10% are operated outside tank at off loaded capacity. Centrado Transformer are designed base on required voltage and capacity.LOW VOLTAGELow voltage tap with unloaded set-up are designed with 133V / 231V (B1) and 231V / 400V (B2) voltage or can be made by combining both voltage simultaneously with definision that loaded voltage are 100% at 133V / 400V. CONTRUCTIONCoil at middle voltage transformer are using high quality copper with enamel isolated and low voltage transformer are using copper foil or covered high quality copper. Middle voltage tap are using Elastimould Synthetic Resin / Porselin Bushing and for low voltafe tap are using Porselin Bushing or mould copper.VECTOR GROUPCentrado transformer are generally designed with two type of Vector such as :" 25 KVA - 160 KVA : Yzn" 200 KVA - 10,000 KVA : DynTo increase your productivity, centrado transformer are being tested at impulse voltage and high voltage adjusted to IEC standard by using Magnetic core made using Grain Oriented Silicon Steel that can add more value to your process. Base on our market riset to maximize customer satisfaction in using magnetic core at centrado transformer, the core are produce with close circuit using V mould with 45 degree to decrease Iron losses and copper losses and reduce operation noise which is help reduce the size of the transformer. Centrado transformer can hold on short circuit and well tested with Routine test, Induced Test, Standard IEC Test and quality check that give us new certication in ISO 9001:2001
