    Leave a Comment

    Dielectric Sciences, Inc. (DSI), a HEICO company, is a small, specialized, and internationally known company, which designs and manufactures cable assemblies, connectors, insulation systems, and accessories for high voltage applications in the medical, industrial, and military sectors. Currently in its 52nd year of operation, DSI has a reputation for deep expertise in designing high voltage connectivity systems that meet the demanding needs of their customers. DSI is looking to add a High Voltage Engineer to its production team in Chelmsford, MA.

    Responsibilities

    The High Voltage Engineer will provide design leadership for high voltage cable assemblies up to 1 MV for medical x-ray, military radar, pulsed power systems, accelerators, and high energy physics programs.  This position will include engineering, project management, business development, and production support. The High Voltage Engineer will determine design requirements, conduct electric field analysis, perform developmental tests, and provide solutions to complex high voltage insulation problems.

    Requirements

    The candidate shall have a MS in engineering, preferably electrical or mechanical, with a BS in a closely related technical field. Superior knowledge of dielectric materials (solid, liquid, gaseous, and vacuum) and their processing techniques is required. Familiarity with HV cable manufacture and strong mechanical design skills are required.

    Desired Skills and Experience

    The optimal candidate will act as the primary technical customer interface for new and existing customers.  The ability for some travel is preferred (<10%). The candidate will possess superior presentation skills, both verbal and written.

    Candidates may submit resumes to jgoldlust@dielectricsciences.com.

  2. Variables Involved in High Voltage Cable and Assembly Design

    Do you need a cable for your high voltage application?  The right cable will ensure that your systems work efficiently and aren’t affected by environmental conditions. Here’s some of the important variables to keep in mind when choosing the right cable for your application:

    • Electrical properties
      • Voltage/current level
      • AC vs. DC vs. pulse
      • Impedance
      • Inductance
      • Capacitance
      • Resistance
      • For AC cables: AC frequency
      • For pulse cables: pulse width/rise time/rep rate/amplitude/attenuation
    • Physical properties
      • Number of conductors
      • Shielded or unshielded
      • Insulation material
    • Environmental considerations
      • Working temperature
      • Insulation media
      • Atmosphere (vacuum, standard air pressure, elevated pressure)
    • Geometric considerations
      • Run length
      • Diameter
      • Flexibility
      • Dimensional tolerances
    • Availability
      • In stock vs. custom order

    We offer over 200 high voltage cable configurations to choose from, with many available in our online catalog, and if we don’t have exactly what you need, we can design a cable that is just right for your application. Contact our engineering team today to get started.
