ESAW Resistance Boxes Plug Type (EEC-10394)

Construction Details:

• In plug type resistance box the contact between plug and socket is the most important feature affecting destructibility of results. We use tapered brass plug and split block. Although expensive to make, this is the best form of contact. It requires accurate machining to ensure interchange ability (i.e. plugs and lugs are cut to a fine taper and are interchangeable.). The plug heads are machine molded, are of heavy insulated Bakelite in a beautiful shape.

• Selected double cover Eureka or Managanin wire is wound on the bakelite spool. Sufficient heat treatment is processed through to avoid any appreciable shifting of values.

• The coils are mounted on the lower side to an insulating panel with the help of threaded brass leads and connected across the gap between the heavy brass blocks which are mounted on the panel. The top panel is provided with two heavy type brass terminals.

• The coils are clearly marked on the panel. The case is made of teak wood.
