Transformers and Filter Reactors MIL-T-27A HERMETICALLY SEALED NEW EQUIPMENT COMMERCIAL GRADE CONTROL and POWER CIRCUIT CHICAGO hermetically-sealed transformers are designed and built in accordance with MIL-T-27A Grade 4, specifications for Class R operation. Other units are listed for Class S operation. All units fully meet the rigid requirements for guided missile, military airborne and ground communications equipment, marine equipment, and in any field where a maximum of sealing quality construction is important. They are especially useful in research and development applications, pilot runs, and pre-production models. To indicate the construction characteristics of this CHICAGO transformer line, the MIL-T-27A specifications require that the transformers be: 1. Temperature and Immersion cycled for 5 complete test cycles of five steps each in temperatures varying from (Plus 85°C. for Class R; Plus 108°C. for Class S) to minus 55°C. including a 25°C. saturated salt water immersion step. 2. Moisture resistance tested in temperatures varying from plus 65°C. to minus 10°C. at 90-95% relative humidity for ten 24 hour cycles extending over a ten day period. 3. Tested for insulation resistance in excess of 1000 megohms after being subjected to tests 1 and 2. 4. Tested on each winding at twice the rated A-C voltage and frequency. 5. Operated for 48 hours with 12% overload at rated ambient temperature with no resultant damage either electrically or mechanically. 6. Subjected to severe vibration tests on a shake table for a period of 2 hours in each of three perpendicular planes. 7. Subjected to 10 impact shocks of 50 gravitational units acceleration in each of 3 mutually perpendicular planes. 8. Capable of operation in 65°C. ambient temperature with a temperature rise not exceeding 40°C. except that the special Class S units can operate in an 85°C. ambient with a temperature rise not exceeding 45°C.
