Requirements imposed on distribution and control systems have also become more complex in line with the diversification of demand for electricity. In this area, we leverage our advanced technology and the know-how that has been cultivated through our extensive track record to consistently provide optimal systems to our clients.

金属閉鎖形スイッチギヤ

Switchgears are used for high-voltage and extra-high-voltage power distribution in facilities containing high-capacity electric installations. Power plants; substations; steel mills; petroleum, chemical, and other large plants and factories; water, sewage, and other public facilities; and large buildings are some of the more common examples of sites where switchgears can be found.

Receiving, distribution, and auxiliary equipment are housed in a single grounded metal-enclosed box and parts are segmented by function to ensure a greater level of safety. Models are identified with reference numbers according to structure, material, form, and other variables. MWG models collectively refer to metal-clad switchgears, drawer-type devices, and main circuit busbar insulation.

キュービクル式高圧受電設備

Harnessing switchboards used to receive electricity supplied by an electric power company, these units are applied to high-voltage (6.6 kV) power-receiving systems with installed power-receiving capacity of up to 4,000 kVA. Everything from main shutoff devices to step-down transformers and breakers for distribution lines are housed in metal boxes.

The unit is referred to as a CB model where the main shutoff device is a high-voltage AC circuit breaker and as a PF/S model where the unit does not include a protection relay or other such component thanks to the use of a fuse-switch combination for installed power-receiving capacity of up to 300 kVA. Structurally speaking, we also offer cubicles for outdoor or indoor environments as well as thin-style cubicles to match the attributes of the installation site. Certified cubicles designed to secure a reliable source of emergency power to be supplied to firefighting systems and other such equipment are also available.

制御盤

Control panels are devices primarily used to operate, protect, and monitor electric motors (air-conditioning equipment, fans, and pumps) and other such equipment. For this purpose, they house circuit breakers, switches, protection relays, and other such components.

There are control panels for use outdoors or indoors depending on the location site and wall-hung or free-standing control panels according to size. We also offer certified control panels for disaster-prevention systems.

分電盤

Distribution boards distribute electricity diverted from a main line to electric light fixtures (lighting and outlets) and motor circuits. In order to protect these circuits, these boards house molded-case circuit breakers, switches, and other such components. In addition, distribution boards are also used to perform lighting control for illumination and operational control for small electric motors.

There are wall-hung or free-standing distribution boards according to size as well as shaft-type boards for which doors are not required due to their being installed inside pipe shafts. We also offer certified distribution boards for disaster-prevention purposes.

PDU

PDUs (power distribution units) are a type of highly functional and reliable distribution board used to receive electricity supplied by UPS (uninterruptible power supply) units and distribute it to IT equipment (network devices and servers) and other essential services. They are used together with PDPs (power distribution panels) (PDFs) designed to supply electricity to subdivided loads.

20kV級特別高圧配電盤

These switchboards constitute a type of metal-enclosed switchgear used in large plants and wind-turbine generator systems for the distribution of 24 kV of electricity. An air insulation system has been adopted out of consideration for the environment.

太陽光発電関連盤

In solar power generation systems, interconnected boards are used to connect with the power networks of electric power companies. Voltmeters and protection relays required for interconnection and transformers for voltage matching are mounted onto these boards. Connection boxes used to connect power conditioner units to solar cell panels are also available.

UPS周辺盤

When constructing a UPS system, an input transformer panel will be needed to step-down the voltage of supplied commercial power where high-voltage AC inputting is used. I/O boards used when building a system to provide parallel redundancy or a common spare for a UPS system and output branch power boards for securing branch circuits matched to loads are available.
