0.1mm x 250 strands Triple Insulated copper Litz wire
The triple insulation of TIW wire offers many advantages over traditional wire used in high voltage products.
Its sturdy construction ensures greater safety and reliability. Triple insulation provides an additional barrier against electrical breakdown, reducing the risk of insulation failure and potential accidents. This makes it an excellent choice for use in high-voltage environments such as power plants and substations.
The fluoropolymer insulation layer contributes to the excellent thermal stability of TIW wire. It can withstand high operating temperatures without compromising its electrical integrity, ensuring safe and efficient operation even under harsh conditions.
The unique combination of materials used in triple insulation provides excellent resistance to chemicals and solvents, making TIW wire suitable for use in harsh environments where exposure to such substances is common.
