Shemar High Strength Braced Line Post and Insulated Cross-arms (CICA)

Shemar High Strength Braced Line Post and Insulated Cross-arms (CICA)

Braced line posts have enabled compact transmission lines in the voltage range of 115 kV to 230 kV. Now line compaction is being considered at progressively higher voltages (EHV range) to develop structures with better visual amenities, smaller foot print, narrow right-of-way requirements and the economic benefits of lighter construction.

However, at 345 kV and above voltages as the section lengths increase due to electrical requirements, the mechanical capabilities of standard braced line posts with typical components becomes a limitation. The low working performance restricts span lengths and increase overall project cost and construction efforts.

Shemar Braced Line Post Insulators

Shemar Braced Line Post Insulators

The simplest insulator system for compact transmission line construction is a composite horizontal line post. However, line post insulators are limited in their vertical loading capabilities and thus cannot support longer spans or heavier conductor systems. Composite braced line posts are designed for applications similar to a line post but with an added suspension 'brace' insulator to significantly increase the vertical load capacity of the assembly.

Southern States Power System Solutions - STATCOM

Southern States Power System Solutions - STATCOM

Static Synchronous Compensators (STATCOMs) provide a range of benefits to power systems. They can be used to mitigate voltage fluctuations, increase power system stability, and improve power quality. STATCOMs can also reduce system losses, improve the efficiency of renewable energy sources, and support the integration of distributed energy resources. Additionally, they can provide fast-acting reactive power support during system faults, helping to maintain system stability and avoid blackouts. Overall, the use of STATCOMs can lead to a more reliable and efficient power system.

Emission rates of reconditioned, recycled and virgin SF6 gas

Emission rates of reconditioned, recycled and virgin SF6 gas

When it comes to medium and high voltage circuit breakers, there is no better electrical insulator than sulfur hexafluoride (SF6). Unfortunately, the same properties that make SF6 such a great insulating gas also make SF6 the most potent of all greenhouse gases. With the ever-growing challenges of federal & local reporting and a shift towards more eco-friendly practices, the industry is seeking ways to reduce SF6 emissions.

Valmont® Tubular Utility Structures

Valmont® Tubular Utility Structures

Structural strength can come from many places—design, materials, manufacturing. But it can also come from basic physics. For example, the strength and simplicity derived from the circle over its square and rectangular counterparts.

While traditional structural shapes (square and rectangle) have a history of strength and a place in low-profile or low-voltage situations, their complexity and bulk can be unwieldy. However, tubular structures (circular) provide the same strength with significantly less weight, fewer bolts and lower costs.

Southern States RLSwitcher®

Southern States RLSwitcher®

Switching shunt reactors located on the transformer tertiary can impose a severe duty on the connected system, switching device, and shunt reactor. Due to the relatively small inductive current, the interrupting device attempts to clear at a forced current zero causing current chopping. If the interrupter’s contacts have not separated enough to sustain the system voltage, a re-ignition of the arc will occur. These high magnitude and high frequency re-ignitions can shorten the life of the reactor and the switching device.
