FRP reinforced with glass fibers. Numerous achievements as electrical insulation components for heavy electrical equipment, vehicles, and facilities, with thin plates used as shielding plates for circuit breakers and switches!

One of the main materials handled at our factory is an electrical insulation laminated board made by impregnating, layering, and molding glass mat with a specially formulated polyester resin. It features strength, heat resistance, and does not discolor. We have numerous instances of switching from phenolic materials. It also has good machinability, and mass production processing with press cutting is possible for thicknesses below 3mm. We supply electrical insulation components for heavy electrical equipment, railways, semiconductors, and electrical equipment. Thin sheets have been successfully used as shielding plates for circuit breakers and switches. We offer three colors: red, white, and gray. It excels in insulation, arc resistance, and tracking resistance, and has obtained UL standard 94-V0 for heat resistance. The heat resistance class is Type B. We also have a higher grade with enhanced flame retardancy. NEMA standard: equivalent to GPO-2 / JIS standard: equivalent to TL-GEM For more details, please refer to "PDF Download" or feel free to contact us.

• Substation equipment

A new paper substrate with bakelite that maintains mechanical properties while incorporating anti-static functions. It features a superior linear expansion coefficient compared to thermoplastic substrates such as nylon.

With an excellent coefficient of linear expansion, it can be used in a temperature range of 0°C to 120°C without regard to the environment. It maintains the mechanical properties of conventional products, making it highly processable. Compared to general antistatic grades of nylon, it has a higher coefficient of linear expansion, and the small difference between the longitudinal and lateral directions reduces concerns about dimensional changes. Its heat resistance temperature is also 130°C, comparable to that of standard laminated boards. It has high processability and can be used for various applications, including jigs, transport pallets for electronic components, and covers for machine tools. As an antistatic grade, it is valuable for machine parts in environments that dislike dust, such as clean rooms, and for FA parts. We can also accept cutting and processing at our own factory. If there are concerns about scratches due to the black color, masking options are also available separately.

• Synthetic resin fittings

It has excellent electrical properties, mechanical strength, heat resistance, and moisture resistance, making it an FRP that performs well in areas subjected to high mechanical strength and high pressure.

One of the main materials handled by our factory is a laminated board based on glass cloth. Since it uses glass cloth as the base material, it has greater strength than glass mat laminated boards. The heat resistance class is F, and we also handle higher-grade products that enhance mechanical strength. Press cutting processing is possible for thicknesses below 3mm. It excels in electrical insulation, mechanical properties, and heat resistance, and has also passed the combustion test for railway vehicle materials (abbreviated: vehicle material combustion test). We also handle higher grades such as FR-4 grade and G-11 grade. NEMA standard: equivalent to G-10 / JIS standard: equivalent to EL-GEM.

• Substation equipment

A long-selling insulating material that is inexpensive and easy to machine.

It is a laminate made of paper substrate and cured with phenolic resin. It is a highly versatile and inexpensive insulator that is easy to machine. We have extensive experience in power distribution and vehicle applications. It is widely used in distribution boards, transformers, and vehicle insulators. Discoloration may occur over time, but there are no issues with quality. PL-PEV is a high-voltage grade that is a superior version of PL-PEM. Its applications are not significantly different from those of PL-PEM, but it is often used when electrical properties are required. Its strength is inferior compared to glass laminates. JIS standards: PL-PEM, PL-PEV *We also handle paper substrate phenolic resin laminates that comply with the combustion test for railway vehicle materials.

• Substation equipment

It is an insulating board made by heating and compressing Kyocera Chemical's BMC premix material.

It is primarily composed of unsaturated polyester resin. We have a track record of insulating parts for distribution boards, vehicle components, heavy electrical equipment, and more, including parts for railway vehicles and insulation components related to plant construction. The heat resistance is typically 150°C. Compared to polyester glass mat laminated boards, its strength is inferior. However, it excels in electrical properties and heat resistance. It also has excellent machinability, making it usable as various structural materials. There are several grades available, each with its own characteristics. We stock the general grade TC-F1. We also have grades that are resistant to salt, chemicals, acids, and sulfuric acid. All grades are available for handling.

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at TSP Corporation. ~ In the case of TSP ~ Before the introduction, there were challenges such as dealing with the "paper" sent from various locations and the reliance on specific individuals for the tasks. After the introduction, the input and checking of FB data, which used to take 2 to 3 hours, can now be completed in just 5 minutes. Additionally, the mindset of the accounting department, which was previously reliant on manual entry, has changed. [Case Overview] ■ Challenges before introduction - Dealing with "paper" sent from various locations, reliance on specific individuals ■ Key points of introduction - A robust support system for setup and operation - Easy to start from a small scale both financially and functionally *For more details, please refer to the related links or feel free to contact us.

The facility operating the nurse call system has made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
