Energy Blog Post - Designing Cable Assemblies for Transformer AppsCable assemblies are a crucial component in transformer applications, as they are responsible for transmitting electrical power and/or signal to operate and monitor the transformer.

 

There are several types of cable assemblies used in transformer applications, including bus bar assemblies, grounding cables, and high-voltage cables.

 

  • Bus bar assemblies distribute electrical power within the transformer. They are made of copper or aluminum and are designed to handle large amounts of electrical current.
  • Grounding cables safely ground the transformer, protecting it from electrical surges and reducing the risk of electrical fires.
  • High-voltage cables transmit electrical power from the transformer to the electrical devices being powered. These cables are designed to withstand high voltages and must be properly insulated to prevent electrical accidents.

 

When selecting cable assemblies for transformer applications, it’s important to consider the type of cable, the size of the cable, and the operating environment.

Cable harnesses and assemblies that are too small may not be able to handle the electrical current transmitted, while cables that are too large may be unnecessarily expensive. It’s also important to select cables that are suitable for the operating environment, as cables that are not rated for the temperature or humidity of the environment may fail or malfunction. Factors such as sunlight and rodent resistance can also play a factor into proper selection of cable materials.

 

The environmental conditions are also a key factor. Douglas Electrical Components manufactures hermetic electrical feedthroughs for transformer applications. These transmit power and signal in various environments that can experience weather conditions, flooding, and submersion. Hermetic electrical feedthroughs create a moisture-tight seal that are Helium leak tested at our factory to ensure transformer equipment is kept safe. We have decades of feedthrough experience that not only seals the cable jacket, but also the conductors within the assembly.

By choosing the hermetic feedthroughs and right cable assemblies, you can ensure that your transformer is able to transmit electrical power safely and efficiently. This is crucial for the proper operation of your electrical devices and helps to protect against electrical accidents and downtime.

DuctorSeal is the Douglas Electrical product series dedicated to hermetic wire and cable assemblies. It is available with designs for hazardous and non-hazardous areas. Combine the number of conductors, wire gauge, and lengths with a mechanical interface that simplifies installation to create a hermetic wire solution for your needs. Integrate various design features including in-line/integral connectors, braiding, twisted wires, as well as various types of wire through a single hermetic assembly.
