For many years, Arthur D. Riley's Power Distribution and Control division has supplied power products to major utilities and industry throughout New Zealand. One of our more unique products developed specifically for NZ is our Ring Main Unit (RMU) - HALO. It's 11kV switchgear, and there are many of them located on roadsides and substations throughout New Zealand.
When these events happen, our power utility customers use the HALO device to isolate power in the affected area, instead of it running continuously and potentially causing more harm to individuals or damage to property.
What makes the ADR HALO unit stand out amongst its peers is its environmentally friendly configuration. Historically, units like these operated with gas, but the HALO utilises new technology. Not requiring gas reduces any negative impact upon the environment which is increasingly being brought into question.
This is a feature that is rare in these kinds of units; the technology is not yet widely used in the marketplace. As companies and utilities begin to focus on their environmental footprint, demand for units like the HALO is increasing. Within New Zealand, we’ve seen increasing demand to reduce our reliance on gas, and the ADR HALO is one of few options in the market that meet this environmental remit.
However, the use of this new technology means that the HALO unit is not as cost-effective as the gas options at purchase, but investment in them brings other benefits to off-set the initial cost difference. Being gas-free, they're ultra-low maintenance and don't require regular inspections like gas units. What near-zero maintenance means is:
The HALO initial investment is paid off over their 30 year lifespan. They're also highly durable. Being very compact units manufactured from stainless steel, they are built to weather New Zealand conditions better than their elect steel counterparts, meaning:
The HALO unit is modular, meaning they can be easily configured to any customer's specific needs. ADR can create a bespoke HALO solution that is tailored for individual requirements. The compact design also means intuitive operation providing increased operator safety.
In terms of automation the HALO:
Historically, the type of switchgear that has been in use in New Zealand for decades has been effective, but environmental challenges and conditions required new technology. ADR have harnessed that technology and HALO is the result - the next evolution in ring main unit switches.
