The water-oil insulated tube is a type of insulating tube used in insulation breakdown tests to understand the aging condition of CV cables that have been removed from actual power equipment. It is inserted into the cable termination to relax the electric field using water and oil. In this test, an AC high voltage is applied to the removed CV cable with the aim of causing insulation breakdown in the effective electrode part (XLPE). However, at the cable termination (end part), the equipotential lines and electric field lines become skewed, concentrating the electric field, which leads to breakdown occurring near the outer conductor of the termination. By using the "water-oil insulated tube" to fill with water and oil, the stress of electric field concentration at the termination is reduced, and the potential gradient becomes gentler, allowing for the voltage to be increased to the point where insulation breakdown occurs in the effective electrode part. Our company has a long-standing track record of being a partner to research institutes related to power, involved in the termination processing of insulation breakdown tests for removed CV cables (3.3kV to 22kV) as well as the production and experimentation of water-oil insulated tubes. Based on our experience and technology related to this test, we can design and manufacture water-oil insulated tubes according to cable diameter and voltage. Recommended for those who: - Want to observe water tree degradation phenomena - Want to understand the aging condition of CV cables.

The "Drone Magnetic Field Resistance Performance Verification Test" allows for the actual flight of the drone body, enabling a quantitative understanding of sensor abnormalities caused by magnetic field influences. We provide a testing environment for evaluating magnetic field resistance performance under three conditions: alternating current at 50Hz for the eastern Japan region, alternating current at 60Hz for the western Japan region, and direct current assumed for railway overhead lines and direct current transmission lines, as well as exposure to horizontal and vertical magnetic fields. This allows customers to operate and fly the drone themselves and confirm the effects on the aircraft. [Features] ■ Quantitative understanding of sensor abnormalities caused by magnetic field influences ■ A testing environment that allows customers to operate and fly the drone themselves to confirm the effects on the aircraft For more details, please download the PDF and view the brochure.

The small magnetic field measuring device "TMM-II" is a compact instrument that allows for easy real-time monitoring of magnetic field measurement values and composite values along the X, Y, and Z axes on-site. It incorporates a small three-axis hollow concentric coil as a sensor, enabling accurate measurements of magnetic fields from any direction in space. Additionally, the positions of the three-axis sensors are displayed on the panel surface with magnetic field component marks. Please make extensive use of it for measuring the electromagnetic field environment around power transmission and distribution facilities, as well as household appliances. 【Features】 - Simultaneous display of magnetic field measurement values and composite values for each axis (X, Y, Z), making measurements easy. - The magnetic field measurement range is from 0.01 microtesla to 625 microtesla. - The measurement range is auto-ranging, providing excellent operability. - The measurement frequency range is from 40 Hz to 1,000 Hz, with a deviation of within ±2%. - Equipped with a hold function for convenient reading of measurement values and magnetic field waveforms, among other features.
