Hitachi / JAEPS has the capability to provide complete GMCB solutions including design, manufacture, testing, installation and commissioning. Our GMCBs are capable of interfacing with all types of Isolated Phase Busbar (IPB) designs.

Isolated Phase Buses (IPB) provides a high degree of reliability and maximum protection for the generator and for other connected equipment. Hitachi / JAEPS offers the design and manufacturing of IPB.

Lightning Arresters (LA) provides protection against lightning strikes on site. Hitachi / JAEPS provides LA that offers superior lightning protection and withstanding multiple strikes.

To ensure stable, high quality power, plant systems connections must be flawless. Hitachi develop and manufacture stationary reactive power compensators, frequency converters and DC power delivery systems that guarantee optimum connections. Our electrical systems, moreover, feature highly advanced digital protection and control technologies.

Shunt Reactors are a vital part of the efficient operation of long transmission high voltage power lines. Hitachi / JAEPS Shunt Reactors offer the most cost efficient mean to compensate the capacitive generation.

Substation technology plays an important role in supplying stable and high-quality electric power. To meet these requirements, Hitachi / JAEPS is always continuing research and development of advanced technology Switchgears in Substation Systems (Ultra-High Voltage, High Voltage and Medium Voltage).

Hitachi / JAEPS provides various high-voltage and high-power testing services through its world-ranking testing laboratory and sophisticated technologies certified in accordance to ISO/IEC17025 standards.

Hitachi / JAEPS offer various proven-design and highly-reliable Transformers that offers excellent mechanical strength for ultra modern plant environment that has been proven through years of service and special testing.

Substation System project involves a highly complex process, from the initial inquiry right through to operation and maintenance. At each stage of such a project, the client will have specific requirements which demand a smooth, coordinated response from the supplier. Hitachi / JAEPS are able to answer these needs promptly and efficiently.

High quality Vaccum Interrupters (VI) in compact body designs are offered in broad ranges for circuit breakers, switches and contactors.

Hitachi Cubicle Type Vacuum Insulated Switchgear (C-VIS) is made up of the vacuum insulated switch and grease-free hybrid type electro-magnetic actuator components. With Hitachi’s expertise in vacuum technologies, the C-VIS was engineered to possess the reliability of Gas Insulated Switchgear (GIS) while allowing the accessibility of the Air Insulated Switchgear (AIS).

The C-VIS is environmental friendly as it is SF6 Gas-free.
