Using Transformers | MuleSoft Documentation transformers are easier to use than custom transformers. You don't need to know the Java name of the transformer, and all properties are explicitly declared in a Mule configuration schema. Following is an example of declaring the standard Append String transformer, which appends string text to the original message payload:
Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.

GIS or Gas Insulated Switchgear | Electrical4U· SF 6 gas pressure for insulating purpose is generally kept below 2.5 bar whereas SF 6 gas pressure for interrupting purpose is ranged from 5 bar to 7 bar. As vacuum technology is not available for high voltage, so for GIS or gas insulated switchgear system above 72.5 KV, only SF 6 is used both for interruption medium and insulation.
