Our Products
Ehouses & Substations
JRS manufactures a wide range of prefabricated electrical/mechanical buildings (e/m-houses), from small 8’ x 8’ sheds to modular buildings of 100’ x 45’ or larger. We are prepared to install and integrate a wide range of equipment including transformers, switchgear, VFDs, MCCs, HVAC, generators, and other industrial equipment.
Power Factor Analysis & Capacitor Bank Systems
JRS can build and install automatic power factor correction (APFC) equipment for the 480-600 volt systems of the indoor type to 750 kVAR. Models APFC-100, APFC 101, and APFC 102. JRS also has the capabilities to manufacture power factor correction systems for the 5 kV and 13.8 kV systems up to 4000 kVAR (4 MVAR) for mining and distribution facilities. All systems use CSA-certified components and are certified completed units to CSA standards. Power factor correction systems lower the current drawn by the system by adding internal reactive power loading, thereby increasing power factor towards unity. This prevents situations like over-heated conductors and damaged motors and VFD drives due to distorted supply currents. APFC systems can reduce your electricity bill and save you from costly equipment repairs.
Power Skids
Designed and fabricated to accommodate various electrical components on a skid or platform for easy transportation, installation, and relocation.
Mine Power Skids & Mine Duty Voltage Boxes
These are skid-mounted, designed to hold up to harsh mining environment, and have high-voltage input with load interrupter switches up to 15 kV. Mine-Duty MV Junction Boxes are used to provide a suitable point for termination, connection, and splitting of medium voltage mining cables. They are available from 5 kV to 25 kV.
Switchgear/Motor Control Centres, Transfer Switches
Custom engineered MV switchgear for applications ranging from 5-25 kV, 600-4,000 A integrating breakers, load break switches, protection and metering devices from all major OEMs. Also available in arc-resistant version.
Crypto Mining Infrastructure
Our standard 300 kW mine vaults are designed to accommodate up to 70 Bitmain Antminer S19 Pro miners, but can be modified for use with other mining units. We understand different mining sites have differing requirements, so JRS experts can custom design mining enclosures and substations to meet the needs of any site.
