Trumpy,
In my plant we have voltages since 110Vac up to 230kV... but in my case, I'm usually involved with 440Vac only. Some times I'm involved with 4,16kV but it happens with lower frequency.
My main interest in discuss insulating gloves is because we have some variable speed drives - very strong but extremely obsolete (it is at least 20 years old). We have several of them (about 50units since 75HP up to 800HP)..... we are gradually replacing for modern ones but it will spend some years.
For while....during the the electrical troubleshooting, the electrician is exposed to electrical shock and arc flash because it's necessary to keep the equipment turned on to find problems in so obsolete equipments. There are control voltages (very low), but there are exposed points with power circuit where the existing voltage are technically classified as low voltage but really dangerous... for example 460Vac, 760Vdc...
For safety reasons, we got to use a garment made by nomex involving almost completely the body of the electrician. There is a transparente window at the level of his head to permit the electrician see around.
The ppe is really good but there are some opportunities I'd like to try analyse. The gloves made by nomex is a litle poor in terms of keep the sense of touching small check points(existinng in electronic plates). That's why I'm trying to explore the experiencies of our mates in terms of options, manufacturers, materials and so on to be used in low voltage equipments.
The main property (or quality) I'm looking for is good insulation (about 1kV is enough) but keeping good sense of touching.
best regards,
Emilio Josino
