Dry-Type Transformers
Autotransformer
V.B. Powernet Autotransformer is a continuous on a single winding transformer coils act as a primary and secondary voltage. They are linked together or interconnected into one to produce different voltages. It has the usual magnetic core but much lesser in volume. V.B. Powernet Autotransformer is more economical and physical smaller in terms of weight and dimensions than two windings transformer.
It is commonly use for loads like motor compressor, lighting, or other loads not required special transformer and configuration.
General Purpose Transformer
The General Purpose Transformer built by V.B. Powernet is the standard design two windings dry transformer. It is available in any winding configuration or vector diagram which is prepared by electrical designer. It is commonly use for supplying appliances, lighting, heating, motorized machines, and power loads.
Is designed to reach rated temperature rise above ambient when operated continuously at rated voltage frequency and loads.

Aluminum Conductor
K-Rated Transformer
V.B. Powernet designed and manufactured k-rated dry-type transformer such us K-1, K-4, K-13, and K-20 rated. Available for aluminum and copper conductor. A K factor rated transformer is used to deal with harmonic loads. The transformer sized appropriate to handle the additional heating cause by non-linear loads. The K-rated transformer works it is uses a double size neutral conductor (200% than normal).
VB Powernet K-Factor Rated Transformer
K-1 Rated – For linear loads, standard transformer, or 15% harmonic current produced by equipment.
K-4 Rated – Used for induction heating, SCR, AC Drives, or where 35% harmonic current produced by the loads or equipment.
K-13 Rated – Used for school pulse lighting, hospital UPS, and other sensitive loads where electronic equipment represent up to 75% of the loads.
K-20 Rated – Used for data processing computer room, or very sensitive loads where 100% of loads is electronic equipment.
Shield in circle
Electrostatically Shielded Transformer
V.B. Powernet shielded isolation transformer usually configured as delta-wye connected. It is to convert 3 wires input to a 4 wires output with stable neutral buss for the power supply wiring going to sensitive equipment.
Providing an electrostatic shield or faraday shield between the primary and the secondary windings thus avoiding transformer of surge voltages passing through inter-winding capacitance and also to softening of high frequency noise from the input side by the neutral inductance of transformer.
