hvGrid-tech manufactures the EHV range of AC Type pre-pressurized dielectric fluid reservoirs for self contained fluid filled (SCFF) cable applications. AC Type pre-pressurized dielectric fluid reservoirs permit a positive dielectric fluid pressure to be maintained along a SCFF circuit during normal and extreme operating conditions.
Dielectric fluid feeding is accomplished through the use of nitrogen pressurized cells, surrounded by the dielectric fluid within the tank. The pressure-volume characteristic of each reservoir is determined by the amount of gas in the cells as well as the pressurization level. The size and pressure setting of the reservoir is determined by the cable system profile and operating parameters.
The standard reservoir shell is made of mild steel and coated with an epoxy resin paint. A stainless steel tank can also be supplied for corrosive environments, and for direct buried applications. Reservoirs can be supplied with wide range of dielectric fluids subject to specific customer requirements.
