NOJA Power Expands Solid Dielectric Load Break Switch Manufacturing Capacity
Australian Switchgear Manufacturing firm NOJA Power confirms the expansion of manufacturing capacity for their Solid Dielectric insulated Load Break Switch, known as the NOJA Power VISI-SWITCH®.
The NOJA Power VISI-SWITCH® is the world’s first Solid Dielectric enclosed Load Break Switch with visible isolation. Unlike legacy technologies, the NOJA Power VISI-SWITCH® has zero SF6 gas insulation, instead relying on a solid dielectric insulation system.
NOJA Power VISI-SWITCH’s rolling off the production line in Brisbane Australia.NOJA Power have developed expertise in solid dielectric insulation through their OSM Recloser product, which has seen almost 100,000 installations in 105 countries worldwide over the last 20 years.
Applying this technology to a Load Break Switch architecture, NOJA Power now provides a sustainable alternative to the incumbent SF6 products on the market today.
The NOJA Power VISI-SWITCH® consists of an enclosed air-break isolator and vacuum interrupter in series, operated by a mechanical sequencing mechanism. With this design, the vacuum interrupter is responsible for all electrical makes and breaks, while the isolator provides all the necessary BIL to meet standards for a point of isolation.

This viewing window allows operators to visibly confirm the point of isolation prior to linework, providing a safety advantage and peace of mind.
NOJA Power is expanding production capacity for the NOJA Power VISI-SWITCH® at their Brisbane Manufacturing headquarters. As more utilities worldwide seek to eliminate SF6 gas insulation from their distribution networks, NOJA Power is providing a viable option to make that transition with reasonable lead times.
“We are pleased to see the NOJA Power VISI-SWITCH® now rolling off the production line as it is the perfect solution to eliminate the use of the SF6 gas switches in our customers networks and help them take further steps to achieve their net carbon zero targets,” says NOJA Power Group Managing Director Neil O'Sullivan.
