3 Phase Transformer 10 KVA – 250 KVA
BORRITECH TRANSFORMER 10KVA – 500KVA
– What is a Borritech 3-phase autotransformer ? A 3-phase autotransformer is a transformer with only one type of winding, meaning the primary and secondary windings are connected together. The 3-phase voltage taken from the autotransformer depends on the number of winding turns.
– 3-phase transformer is used to convert 3-phase 380v voltage to 200v – 220v 3-phase voltage without changing the frequency for use with imported equipment from Japan, USA, Taiwan… and other special needs.
– 3-phase input voltage: 380V (For 3-phase lioa transformers with input voltage other than 380V, they are manufactured upon request)
– 3-phase output voltage: Both Japanese standards are 200v and American standards are 220v (For 3-phase lioa transformers with capacity less than 200kva)
– 3-phase output voltage: Only one of the two Japanese standards is 200v or the American standard is 220v (For 3-phase lioa transformers with a capacity greater than 200kva)
– 3-phase output voltage other than 200v 3-phase and 220v 3-phase is produced upon request
– Frequency: 49 – 62HZ
– Electrostatic painted machine body
– (V) and (A) clocks are clearly displayed
– Overload and short circuit protection with circuit breaker

Characteristics of isolation transformers
Unlike autotransformers , isolation transformers consist of primary and secondary coils that are only connected by a magnetic field. The separate coils are electrically independent and create the following unique features of the isolation transformer:
- Any point on the secondary coil has a voltage of 0 compared to the ground. Therefore, when we touch any point on the secondary wire, we will not be shocked , the voltage only has a difference at 2 other points of the secondary coil, this is the biggest advantage of the isolation transformer, it helps to limit the risk of electrical leakage in the device shell and brings safety during use .
- Each primary or secondary winding has a different Volt-ampere characteristic according to the ratio of turns on the primary and secondary districts.
- The current generated from the secondary coil in an isolation transformer is a variable alternating current .
- Isolation transformers are machines with quite low impedance. On the other hand, they use electrostatic shielding between the primary and secondary wires, so they are able to resist surge power sources, prevent harmonic interference from other devices in the electrical system, and prevent electric shock.
- RF isolation transformers eliminate low frequency radio resonances and prevent surface leakage to reduce RF burns.
