AEM - High-Voltage and Medium-Voltage Switchgear

AEM is a leading manufacturer of high-voltage power transmission and medium-voltage power distribution equipment, specialising in network switch and disconnector solutions from 12kV to 362kV, up to 4,000A.

Transmission and distribution authorities throughout Australasia use AEM products in transmission substations, terminal stations, zone substations and for underground power cable and overhead power distribution networks. AEM offers reliable products certified to relevant AS and IEC standards.

Reliable high-voltage and medium-voltage switchgear

AEM delivers certified, field-proven quality products with short lead times to help you complete substation projects with a minimum of time and cost. Our flexible, capable and experienced design team produces site-specific designs to meet your needs and standards.

Our products are produced using lean manufacturing principles to our ISO 9001-2008 quality system, to ensure that your product reaches site on time and defect free.

High-voltage power transmission products

AEM's HV and EHV power transmission products include:

• HV and EHV disconnectors, manual and automated
• HV and EHV earth switches, associated and independent
• Underground cable cross bonding link boxes

AEM double-break disconnectors and earth switches are rated from 36kV to 362kV. Products can be customised to suit your substation site and local standards with short lead times.

Underground power cross bonding cable link boxes are suitable for system voltages from 33kV to 330kV. AEM sheath earthing solutions minimise earth sheath losses.

Self-healing smart grid distribution solutions

• The self-healing distribution system increases network reliability, safety, and availabilityM
• Recloser, sectionaliser and load break combinations for ring and radial networks, providing automatic, autonomous fault detection, isolation, restoration and reporting (self healing)
• Reliable detection of high and low impedance faults, including SEF and true open conductor detection

Medium-voltage power distribution products

AEM's range of medium-voltage power distribution products includes:

• Air break switches and disconnectors
• Self-healing distribution automation and protection equipment: load break switches, sectionalisers and reclosers
• Pad mount switchgear: ring main, load break and transfer switches
• Single-phase links and fuses: disconnector links and solid links
• Accessories and spares: hook stick actuators, distribution insulators and spare parts

High-voltage installation and commissioning

Our high-voltage installation and commissioning team can safely and quickly install high-voltage and extra high-voltage disconnectors for a long and trouble-free life.

We have the knowledge and expertise to retrofit and upgrade older installations, and we can offer responsive site support for installations by others.

Engineering design services for outdoor switchgear

Our engineering design team can design outdoor switchgear to suit your site conditions and standards. Our local knowledge and presence ensures that project deadlines are met, even when unexpected issues arise on site. Every product, customised or standard, is fully documented with drawings, installation and operating instructions. Our service includes:

• Engineering design
• Site assessments
• Risk assessments
• Product development and adaptation
• Type testing
