Instrumentation Transformers

ITT

We represent Instrument Transformer Technologies Ltd of South Africa, ITT is the largest manufacturer of the Southern Hemisphere of Instrumentation Transformers, a company with presence in Asia, Australia and America, is known for its very high quality products in line with the high prestige of South Africa as A manufacturing of engineering products is concerned, ITT has IEC and ISO9001 certifications. ITT’s products and services offer includes the manufacture of current and voltage transformers (from 3.3kV to 132kV) and measurement units from 6.6kV- 33kV for pole and ground mounted applications.

Auri Business is the exclusive representative of ITT and helps you select the best equipment for your project, all payments are made 100% directly to our represented company without increasing any commercial margin, and we as an Auri Business can optionally handle all the logistics and processes Customs from the departure of their transformers from South Africa to the delivery at the door of your company, we are aware of the local legislation regarding the importation of electrical equipment in general in each country we represent and it is very certain that the prices you can get with We for the purchase of their transformers are unbeatable.
ITT products are aimed exclusively at electricity transmission or distribution generating companies, as well as large consumers of energy such as mining, shopping centers, large industry among others, which, due to their business activity, require the measurement of electrical parameters in HIGH VOLTAGE up to 132KVThe countries where we represent ITT exclusively are: Peru, Chile, Colombia, Ecuador, Bolivia.
