Due to the higher voltages on the utility side, primary/HV bushings are often the dead front type. The fully insulated dead front apparatus limits exposure to higher voltages and reduces the risk of arc flash for utility workers and other qualified persons accessing the HV cabinet while the transformer is energized. Another advantage of dead front bushings is that they reduce electrical clearances between bushings—allowing for a smaller overall cabinet size. The live front bushing type is still occasionally used for primary/HV bushings, however, it is less prevalent nowadays in padmount transformers.

Because the dead front interface typically allows only one cable connection per elbow connector, it is uncommon to see it used for transformer secondary/LV terminations (where multiple cables are landed on each phase). The most common deadfront interface (load break) has a current carrying capacity of 200 amps; 600 and 900 amp ratings are available with non-loadbreak (or deadbreak) type interfaces as well.

We can provide multiple connection styles as well as tailor-made solutions according to almost any kind of customer requirement/specification.
