The ITV cameras, fire alarms, and internal broadcasting equipment also have a lot of achievements in lightning protection measures!
We would like to introduce examples of lightning damage countermeasures for electrical equipment in factories. In advanced factories, all equipment is highly digitized and interconnected through a network. As a result, damage in one area can often spread throughout the entire network, making it necessary to consider lightning protection measures for the entire factory. Our company focuses on lightning protection measures through on-site surveys, and we have a track record of implementing these measures in factories across various locations. We have received particularly high praise for our countermeasures concerning power equipment, such as servers, inverters, and DC power supplies, which are significantly affected by lightning, as well as instrumentation devices that are essential for plant operations. 【Main Lightning Protection Products (Partial)】 ■ Surge Protectors for Power Supply ・VAJ Series ・VNJ Series ■ Surge Protectors for Communication and Signal ・VTJ Series ・VCJ Series *For more details, please download the PDF or feel free to contact us.
Power supply SPD with pressure-resistant explosion-proof structure used in explosion-proof areas such as petrochemical plants.
The "EX-P type" is a power supply SPD (surge protective device) with a pressure-resistant explosion-proof structure, used in explosion-proof areas such as petrochemical plants and heavy chemical factories. It implements the MZS-200AV type SPD for power supply, compliant with JIS C 5381-1 Class I and II. 【Features】 ■ The MZS-200AV type is equipped with a deterioration indication function and an alarm contact output function during deterioration. ■ Certified explosion-proof equipment (Certification number TC19315). ■ Applicable gas or vapor explosion grade and ignition degree: IIBT6 (For explosive gases with an ignition temperature exceeding 85°C and below 100°C). For more details, please refer to the catalog or feel free to contact us.
JIS Class II compatible! SPD that allows remote monitoring of recommended replacement timing via LAN communication.
The "Smart SPD System" is a power supply SPD (surge protective device) that allows remote monitoring of recommended replacement timing based on lightning surge measurement values via LAN communication. In combination with a monitoring unit, it is possible to check lightning surge information and the status of the SPD. This enables replacement of the SPD before it completely loses functionality, eliminating unprotected time due to failure and allowing for efficient maintenance. 【Features】 ■ Visualization of deterioration status with replacement recommendation display ■ Equipped with a color LCD screen for easy management on-site ■ Compliant with JIS C 5381-1 Class II ■ Conforms to the Ministry of Land, Infrastructure, Transport and Tourism's building equipment design standards and the standard specifications for public building construction ■ Compliant with RoHS directive For more details, please refer to the catalog or feel free to contact us.
To build a highly reliable system essential for operation, lightning protection is also indispensable!
We would like to introduce examples of lightning damage countermeasures for electrical equipment at aviation facilities. Airports, with their vast land area and tall structures such as terminal buildings and control towers, have seen an increase in lightning damage frequency due to recent enhancements in transport capacity, which have led to increased flights and larger aircraft being relocated to mountainous areas. To establish a highly reliable system essential for airport operations, lightning protection measures are also indispensable. Our company proposes various lightning protection measures considering different types of lightning damage for various electrical and communication equipment, including apron lighting systems, and installs surge protectors for power supply and communication/signaling purposes.

Attention is needed for lightning surges that wrap around grounding from lightning strikes to lightning rods and similar devices!
We would like to introduce examples of lightning damage countermeasures for electrical equipment in universities (research facilities). Universities (research facilities) have many expensive devices installed, such as precision instruments, research equipment, and supercomputers. In addition to the damage to the equipment itself caused by lightning strikes, the interruption of experiments, loss of observational data, and disappearance of research data due to lightning damage can result in even greater losses. Our company has supplied a large number of lightning protectors, primarily for high-capacity power supplies, to a science and engineering university located in a mountainous area where lightning strikes are frequent and concerns about lightning damage to various equipment were raised. 【Case Overview】 ■ Issues - Attention is needed to ground lightning surges that can wrap around from lightning strikes to lightning rods and other devices. - In cases where there are multiple buildings, the ground potential difference between buildings can cause lightning surges to propagate not only to the building that was struck but also to nearby buildings. ■ Countermeasures: We propose VAJ-type lightning protectors for high-capacity power supplies at the main power distribution panel of floors with critical loads, and VNJ-type and VTJ-type lightning protectors for communication lines and signal lines depending on the equipment situation. *For more details, please download the PDF or feel free to contact us.
The lightning protection measures for the inverter driving the pump have received high praise as our unique proposal!
We would like to introduce examples of lightning protection measures for electrical equipment at water-related treatment facilities. Water supply and sewage facilities are critical infrastructure where shutdowns are not permitted. However, many of these facilities are located in suburban or mountainous areas with frequent thunderstorms, and they often contain instrumentation equipment and telemetry, which are relatively susceptible to lightning strikes, leading to a high incidence of lightning damage. Our lightning arresters are installed on power supplies, communication lines, instrumentation signal lines, inverters, and various equipment both inside and outside the facility, protecting the equipment from lightning. 【Case Overview】 - Lightning arresters are installed on the power supply sections of telemetry panels and instrumentation panels, as well as on telemetry communication lines and measurement signals from field equipment. - We also propose installation on the power supply and signal lines of measurement equipment on the field side. - In cases where wiring distances are long, lightning arresters are installed on self-owned communication lines between equipment and control signal lines between panels. *For more details, please download the PDF or feel free to contact us.
