We can also custom design and manufacture accessories and components for virtually any underground high voltage cable system.

3 Low-Pressure Fluid-Filled Terminations hvgrid s terminations are based upon a proven design with over 50 years of service around the world in operating voltages from 69 kv up to 345 kv. They are designed for paper insulated single conductors, up to 4000 kcmil, to withstand nominal operating pressures of 100 psig (690 kpa) and maximum transient pressures of up to 150 psig (1035 kpa). Stress control within the termination is achieved by utilizing either a stress cone with lip flare, a stress cone with insulated stress ring or capacitance type condenser cone. All terminations are designed in accordance with IEEE Standard 48 for class 1 terminations. Low-pressure fluid-filled outdoor terminations are available in operating voltages from 69 kv up to 345 kv. The termination utilizes a porcelain bushing with a minimum pollution creepage distance of medium level, as classified by IEC 815. Available optional items include 4-hole NEMA pad or universal type aerial lugs, and cast epoxy or porcelain mounting insulators. Low-pressure fluid-filled oil-immersed (cubicle) terminations are available in operating voltages from 138 kv up to 345 kv. The termination utilizes a porcelain bushing specifically designed to be mounted within a metal cubicle filled with dielectric oil, typically inside transformers. The mounting plate of the termination can be custom designed to suit the specific requirements of the cubicle or transformer interface. Low-pressure fluid-filled gas-insulated switchgear (SF6) terminations are available in operating voltages from 138 kv up to 230 kv. The termination utilizes a cast epoxy bushing specifically designed to be mounted within a metal clad switchgear. The termination interface and components are designed in accordance with IEC hvgrid custom designs and supplies terminations that match a variety of mounting arrangements. This allows our terminations to be a compatible replacement for any brand or manufacturer.

4 High-Pressure Pipe-Type Terminations hvgrid s terminations are based upon a proven design with over 50 years of service around the world in operating voltages from 69 kv up to 345 kv. They are designed for paper insulated single conductors, up to 4000 kcmil, to withstand nominal operating pressures of psig (1,380 2,070 kpa) and maximum transient pressures of up to 350 psig (2,415 kpa). A semi-stop assembly is utilized to maintain dielectric fluid inside the termination in the case of pressure loss within the carrier pipe and also to restrict the flow of dielectric fluid in the event of an insulator rupture. Stress control within the termination is achieved by utilizing either a stress cone with lip flare, a stress cone with insulated stress ring or capacitance type condenser cone. All terminations are designed in accordance with IEEE Standard 48 for class 1 terminations. High-pressure fluid-filled outdoor terminations are available in operating voltages from 69 kv up to 345 kv. The termination utilizes a porcelain bushing with a minimum pollution creepage distance of medium level, as classified by IEC 815. Available optional items include 4-hole NEMA pad or universal type aerial lugs, and cast epoxy or porcelain mounting insulators. High-pressure fluid-filled gas-insulated switchgear (SF6) terminations are available in operating voltages from 138 kv up to 230 kv. The termination utilizes a cast epoxy bushing specifically designed to be mounted within a metal clad switchgear. The termination interface and components are designed in accordance with IEC hvgrid custom designs and supplies terminations that match a variety of mounting arrangements. This allows our terminations to be a compatible replacement for any brand or manufacturer.

5 Low-Pressure Fluid-Filled Normal Joints hvgrid s single conductor low-pressure fluid-filled normal joints are based upon a proven design with over 50 years of service around the world in operating voltages from 69 kv up to 345 kv. The normal joints are installed in metallic casings that permit dielectric fluid to flow from one cable section to another through the hollow core inserts of the connector. They can be designed for sectionalized or non-sectionalized applications. Sectionalized joints utilize a cast epoxy joint sleeve insulator to isolate the cable sheaths on each side of the joint. This allows for sheath interruptions or permits sheath cross-bonding which minimizes sheath losses during cable operations. Non-sectionalized joints are used when sheath continuity is preferred for solid grounding requirements. The joint casing can be custom designed to meet the specific requirements of the cable system, taking into account the cable, sheath grounding, oil-feeding, manhole or joint bay configuration. The joints are designed for paper insulated single conductors, up to 4000 kcmil, to withstand nominal operating pressures of 100 psig (690 kpa) and maximum transient pressures of up to 150 psig (1035 kpa). Normal joints are designed in accordance with IEEE Standard 404.

6 High-Pressure Pipe-Type Joints hvgrid s three conductor high-pressure fluid-filled normal joints are based upon a proven design with over 50 years of service around the world in operating voltages from 69 kv up to 345 kv. They are installed in steel pipe sleeves between carrier pipe sections or inside spreaderheads or trifurcators which are installed to separate the three phases into individual riser pipes leading to the terminations. The steel pipe sleeves, which are welded to the carrier pipe through reducer flanges, can consist of a double sleeve or multiple telescoping sleeves. The pipe sleeves and reducer flanges can be custom designed to meet the specific requirements of the cable system, taking into account the cable, carrier pipe, oil-feeding, manhole or joint bay configuration. Aluminum spacers (spiders) are installed to separate the three shielded cores and to counter the adverse affects of thermo mechanical flexing of the cable/joint interface. The joints are designed for three paper insulated single conductors, up to 4000 kcmil, to withstand nominal operating pressures of psig (1,380 2,070 kpa) and maximum transient pressures of up to 350 psig (2,415 kpa). Normal joints are designed in accordance with IEEE Standard 404.

7 Pre-pressurized AC Type Oil Reservoirs hvgrid s pre-pressurized AC type oil reservoirs are based upon a proven design with over 50 years of service around the world. The pre-pressurized reservoirs permit a positive fluid pressure to be maintained along a cable circuit under extreme operating conditions. Fluid feeding is accomplished through the use of nitrogen pressurized cells, surrounded by cable insulating fluid within the tank. The pressure/volume characteristics of the reservoir are determined by the amount of gas in the cells and the pressurization level. The size and pressure setting of the reservoir is determined by the cable system parameters. Pre-pressurized reservoirs can be installed at ground level which eliminates the need for any type of tower structure or elevation differences that are required for gravity feed oil reservoir systems. All the valves and fittings are located on the outer shell for ease of making oil connections and for maintenance. An optional pressure gauge and mounting plate can be located on the outside of the reservoir for easy visibility and accessibility. The reservoir s outer shell can be fabricated from either mild steel or stainless steel and coated with grey epoxy resin paint. The stainless steel shells are recommended for corrosive situations such as coastal or industrial environments, manhole installations and for direct buried applications.
