product description
Description of Diphenyl Ether Tube
Diphenyl ether fiberglass cloth laminated tube is tube-like laminated products, which is manufactured by fiberglass cloth soaked in diphenyl ether resin, and then rolled, backed and cured under heat and hot pressing with good electrical property and strong mechanical processing performance. The insulation class is H class and the main color is dark brown.
Application of Diphenyl Ether Tube
It is suitable for insulating structural spares in electrical equipment, and can be processed into coil insulation cylinder of dry-type transformer and insulation terminal coil of transformer.
Advantage of Diphenyl Ether Tube
Diphenyl ether fiberglass cloth laminated tube, produced by ZTelec Group using Diphenyl ether resin as raw material, can be mass-produced with advanced production equipment and full automatic production line. This product has the advantages of reliable quality, uniform color and neat cutting ends with strict manufacturing technology. Meanwhile, ZTelec Group is equipped with advanced ventilation facilities and dust-removing equipment to keep the products dry and clean.
