Problems in the application of electrical insulation in a partially developed country

The ultimate choice of insulating materials for use in an insulation system for a particular type of electrical equipment is the responsibility of the design engineer. In a partially-developed country like Brazil, however, factors governing this choice may involve so many fields that well-oriented teamwork is sometimes necessary to gather all the information required for a sound decision to be reached. The factors to be considered are, of course, the same in any country, cost usually being the deciding factor. The difference lies in the fact that local conditions may give entirely different weights to the various factors and to the various components of the total cost.
