ＳＤＣ田中 List of Products and Services

The "SDC Current Insulation Bolt" is a set of insulated hex bolts, hex nuts, flat washers, insulated washers, and color caps designed to prevent electrical contact. It is ideal for areas where the flow of electricity must be interrupted and for high-voltage insulation points. In high-voltage situations, it is necessary for the insulation running to completely cover the flange part, and the screws must also be fully tightened, which is why it is sold as a set tailored to various flanges. 【Features】 ■ Insulation effect that withstands AC 2200V (guaranteed at 220V) ■ Excellent workability in dry conditions ■ Capable of preventing chlorine corrosion ■ Effectively prevents seizing ■ Can stabilize torque coefficient values *For more details, please contact us or download the catalog.
