Technical FAQs 4

What is a containerized mobile substation?

Containerized mobile substations are sheltered and address applications in challenging environmental conditions including areas with high pollution, high humidity, extreme temperatures or sand storms. Containers are easy to transport and fast to install, by reducing foundation works as well as installation and commissioning effort on site.

What drives RWW development of containerised outdoor substations?

Customers requiring shorter overall delivery times and minimal on-site work have been the main drivers for RWW development of containerised outdoor substations.

Are containerised substations a good investment?

One key area where big industries can make significant cost savings is by using purpose-made, containerised substations. These repurposed marine shipping containers arrive on-site pre-installed with fully tested switchgear, ready for immediate cable connection. Containerised substations are incredibly useful in remote areas.

What is a containerised substation?

Purpose made substations, housing erected, tested and commissioned indoor distribution switchgear in one complete package. RWW’s containerised substations are designed, manufactured, fully assembled, wired and operationally tested in our workshops, therefore site works are minimised along with delays due to inclement weather.
