Product Description

We manufactured various types of pad mounted transformer according to customer requirements.

Recently exported a top-of-the-line 500kVA pad mounted transformer to Jamaica. The primary voltage of the transformer is 24GrdY/13.8kV, while the secondary voltage is 0.24/0.12kV with two voltages in the LV side,which is precisely the uniqueness of this transformer. This transformer is used in buildings, so it may require two different output voltages to meet the customer's usage requirements. This transformer is designed to be "dead front" and is of the loop type, making it incredibly efficient and reliable. Due to the loop type of this transformer, the high voltage has two sets of incoming terminals and three two position load switches,and there are equipped three bay-o-net fuses and three current limit fuses in the HV room.In LV room equipped with pressure relief device, liquid level indicator,oil thermometer and vacuum pressure gauge.

Technical Data Sheet
 

25 kVA oil type single phase pad mounted transformer specifications and data sheet
 

For each transformer are prepared and issued a test report, in accordance with IEC 60076. except for routine tests, we also offer type tests and specialised tests to meet all customer requirements. We make what matters work for our customers in a safe and reliable way.

Routine test

-Measurement of winding resistance
-Measurement of voltage ratio and check of phase displacement
-Measurement of short-circuit impedance and loss
-Measurement of no-load loss and current
-Dielectric routine tests
-Tests on on-load tap-changers, where appropriate
-Leak testing with pressure for liquid-immersed transformers(tightness test)
-Tightness tests and pressure tests for tanks for gas-filled transformers
-Check of the ratio and polarity of built-in current transformers
-Check of core and frame insulation for liquid immersed transformers with core or frame insulation

Type test

-Temperature-rise type test
-Dielectric type tests
-Determination of sound level for each method of cooling for which a guaranteed sound level is specified
-Measurement of the power taken by the fan and liquid pump motors
-Measurement of no-load loss and current at 90% and 110% of rated voltage

Special test

-Dielectric special tests
-Winding hot-spot temperature-rise measurement
-Determination of capacitances windings-to-earth, and between windings
-Measurement of dissipation factor(tanδ) of the insulation system capacitances
-Determination of transient voltage transfer characteristics
-Measurement of zero-sequence impedance(s) on three-phase transformers
-Short-circuit withstand test
-Measurement of d.c. insulation resistance each winding to earth and between windings

What is Pad-mounted Transformer ?
 

A padmount or pad-mounted transformer is a ground-mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad. These transformer are used with underground electric power distribution lines at service drops to step down the primary voltage on the line to the lower secondary voltage supplied to utility customers.
