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 200 - 300 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 fl uid inside the termination in the case of pressure loss within the carrier pipe and also to restrict the fl ow of dielectric fl uid in the event of an insulator rupture.

Stress control within the termination is achieved by utilizing either a stress cone with lip fl are, 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 fl uid-fi lled outdoor terminations are available in operating voltages from 69 kV up to 345 kV.

High-Pressure Pipe-Type

Terminations

hvGrid’s single conductor low-pressure fl uid-fi lled 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 fl uid to fl ow 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 specifi c requirements of the cable system, taking into account the cable, sheath grounding, oil-feeding, manhole or joint bay confi guration.

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.



Low-Pressure Fluid-Filled

Normal Joints

hvGrid’s three conductor high-pressure fl uid-fi lled 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 fl anges, can consist of a double sleeve or multiple telescoping sleeves. The pipe sleeves and reducer fl anges can be custom designed to meet the specifi c requirements of the cable system, taking into account the cable, carrier pipe, oil-feeding, manhole or joint bay confi guration.

Aluminum spacers (spiders) are installed to separate the three shielded cores and to counter the adverse affects of thermo mechanical fl exing 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 200 - 300 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.



High-Pressure Pipe-Type

Joints

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 fl uid 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 fl uid 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 fi ttings 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.

Cable clamps can be used for LPOF, XLPE, and EPR cables. Typical installation applications include: vertical shaft, termination support, riser pole, tunnel, seismic, manhole/duct entrance, cable tray, and wind towers. Custom clampling solutions are also available for non-standard / special applications.

Cast aluminum clamps are available in fi ve different cable diameter ranges. Each clamp is supplied with stainless steel mounting bolts and neoprene liners. Optional stainless steel springs are available to allow for expansion and contraction of the cable, while maintaining adequate holding force to secure the cable.

Other specialty types of clamps can be custom designed to suit the customer’s specifi c cable dimensions and/or special installation requirements. Examples include single point mounted clamps and multi-cable clamps.

Single point mounted clamps allow clamping in positions where two perpendicular holes to the cable direction are diffi cult to maintain or are not possible (for example, snaking of the cable).

Multi-cable clamps allow more than one cable to be clamped together in the same orientation utilizing only one clamp.

hvGrid-tech Inc. is the North American distributor of ID-Technik fi berglass reinforced cable clamps which are available in a variety of different styles for various cable applications. These clamps are ultraviolet ray protected, fl ame resistant and free from halogens. Mounting hardware, neoprene liners and springs are all optional items.
