Transformer Centrado can stand the test of high voltage dielectric 50Hz/60Hz and the impulse voltage according to IEC standards and the Indonesia Standard.
Adjusted with the voltage distribution system in Indonesia, namely: 6 KV, 12 KV, 20 KV and 24KV. Tapping the primary voltage is done by the commutator (Tap-Changer) in an empty load on the primary side. Centrado also serve special requests other high voltage in accordance with user needs.
Taping system is driven to a voltage adjustment +4%, +2.5% or 5%. For transformers with a capacity above 100 KVA can be made 2 commutator switches the primary voltage / voltage transfer outside the tank construction, making it easier to use with multiple functions can be locked for security.
In the secondary voltage in the empty weight can be 133 V/231 V (B1) and the voltage 231 V/400 V (B2) or can be provided simultaneously, that: the voltage 133 V / 231 V only 75% and the voltage 231 V / 400 V, the power is: 100% of normal power.
- Core transformers: Transformer core is made of Grain Oriented Silicon Steel 0.27-mm M4 is crafted and designed in such a way as to ensure the mechanical strength, reduces vibration and noise with iron losses low.
- Coil: The coil made of copper konstruktivitas value is high, the coil on the high voltage side is made of enamel insulated copper wire, while the low voltage side of the paper insulated wire. Note: If there is a special request for the class of higher insulation materials will be provided. *The core and coil transformer will then be dried with dioven until the insulation resistance up to more than 2000 Mega Ohm.
- Terminal: High voltage terminal using porcelain insulators or Elastimold Synthetic Resins. Low voltage terminal using porcelain insulators with the current above 1000 A with a copper berisloasi Synthetic Resins.
- Tank: Made of steel plate gilded zinc (Electrogalvanized Zin Coated Steel) or Mild Steel Plate. Designed water-resistant construction and air.
- Packing Transformers: Packing the transformer is made of rubber that can resist high temperatures and also has the oil resistance is good.
- Painting: Before the painting process to remove oil and rust are attached to the surface of steel plate, after which painting process followed by painting the bottom end later in dioven certain temperature so that a perfect result.
- Olie: Transformer oil has a double function as an insulating and cooling. By default PLN, Olie transformer used is: SHELL DIALA B “or the like.

1. YORITSU Stabilizer (Automatic Voltage Regulator, Motor made In Japan, Warranty 5 years)
Classic problem we often face in using electrical equipment such as computers, TV, audio & communications equipment OFFICE & HOUSE is less than maximum value such tools to work due to an unstable voltasi. So that these tools are having problems and eventually broken when we bought it not long ago.
In a larger capacity power tools are also used for LABORATORY & FACTORY is required to produce a good product and if the problem occurs the company will be charged a lot which resulted also behind a series of problems, not just a broken machine, but productivity is halted and means the cost for the company.
Are we still maintain these inefficiencies? By saving a little money but wasted too much time and high costs? It’s time you check voltasi today!
