titleOfInvention |
Double insulated heaters for treating subsurface formations |
abstract |
A heater includes a conduit and three insulated electrical conductors located in the conduit. At least one of the three insulated conductors includes an electrical conductor at least partially surrounded by an insulation layer and an electrically conductive sheath at least partially surrounding the insulation layer. One or more layers of electrical insulation at least partially surround the three insulated electrical conductors in the conduit. The one or more layers of electrical insulation electrically isolate the insulated electrical conductors from the conduit. |
