Bending strength test based on JIS K 6911.

Bending strength The bending strength of a 1mm thick test specimen is 450 megapascals. Many GFRP products are molded products based on thermoplastic resins. In contrast, glass cloth-based epoxy resin laminates are made by applying high heat to a substrate based on thermosetting resins while pressing at high pressure, resulting in excellent mechanical strength.

Examples of insulation used around coils (image) are often adopted in a way that they are machined into parts requiring mechanical strength and installed in places where metal would be inconvenient.

Examples of processing into insulating spacers Many GFRP products are molded using molds, but products made from glass fabric-based epoxy resin are obtained by "machining" from the material to achieve the desired shape.

We also offer laminated tubes made of epoxy resin with a glass fabric substrate in the shape of pipes.

Grounding transformer - It is a transformer used for generators such as wind power generation and micro gas turbines, where the neutral point cannot be directly grounded. - It is used to detect zero-sequence current and zero-sequence voltage in the event of a ground fault in the circuit. - Generally, grounding transformers are specified by their short-time rating. - It has a low zero-sequence impedance.

Industrial winding core This is a hollow structure winding core that is coupled via a flange to a tube that matches the chuck of the winding machine and a tube that is optimal in size for winding. To address wrinkles, it is necessary to increase the size of the winding core, but the increase in weight becomes an issue. With a glass epoxy winding core, these problems can be solved simultaneously.

Transformer for Wind Power Generation - A transformer installed inside the tower of floating offshore wind power generation. - Seismic performance that can withstand vibrations with a frequency of 2Hz to 100Hz and an acceleration of 0.7G. - Tilt performance that allows operation without issues even when the transformer is in a tilted or rolling state. - Both primary and secondary sides adopt a close-contact insulation cap structure, further enhancing dirt resistance performance. - It is also possible to have a fixed structure that can withstand transportation in a horizontal position while still installed in the tower.

Pulse Transformer - It is a transformer that supplies high-voltage pulse power to high-power microwave tubes such as klystrons. - The internal wires are firmly encapsulated in epoxy resin, which suppresses vibrations caused by electromagnetic mechanical forces. - By mechanically fixing the primary and secondary coils, the electromagnetic mechanical stress between the coils is enhanced. - It has a large inductance and a small sag. - The rise and fall times are steep, and the back swing is small.

Transformer for Direct Inverter 〇 This is a multi-winding transformer used in inverter devices for energy-saving operation of pumps and motors. 〇 By discarding the secondary winding, it contributes to energy-saving operation with minimal voltage fluctuations, even when connected to high-capacity inverters. 〇 We also accept manufacturing of rare winding types due to impedance matching.

Transformer for UPS (Uninterruptible Power Supply) - UPS systems are often connected to computer-related equipment, and this transformer is designed considering the "harmonics" produced by these devices. - To suppress overcurrent to the UPS device, the inrush current of the transformer is limited to about 1 to 5 times, and it can be designed to accommodate your desired inrush current. - It is strong against short-circuit mechanical forces and can handle multiple operations (more than 5 times per day). - By equipping a contact prevention plate, it can reduce noise above 1 kHz by approximately 30 dB.
