ABZ (Shanghai) Smart Tech Co, Ltd www.abz-sh.com TW dies to draw aluminium strands to ASTM standards India’s Ajex & Turner Wire Technologies designs TW dies in PCD, VNT nano or carbide to draw aluminium strands for producing ACSR, ACCC, ACSS and ACFR conductors (trapezoidal wire) to the ASTM standards approved by most power grid corporations around the world. The company states that its TW dies are designed to ensure accurate quality parameters, to obtain aluminium strands that

are shaped to provide a smooth outer surface that can meet applicable ASTM standards. The dies are made from high- quality raw materials that enable them to be both efficient and long lasting.
