T/CSTE 0106-2021 "Leader" Standard Evaluation Requirements for High-Speed Transmission Wire Extruders and Cage Twisting Equipment

Scope

Scope: This document specifies the terms and definitions, evaluation index system, and evaluation methods for the "Leader" standard evaluation of high-speed transmission wire extruders and cage winding equipment. This document is applicable to the level evaluation of high-speed transmission wire extruders and cage winding equipment products in enterprise standards for special electrical wire and cable equipment. Relevant institutions can refer to this document when formulating "Leader" evaluation schemes for enterprise standards. Enterprises can also use this document as a reference when formulating enterprise standards. Main Technical Content: 4.2 Classification of Evaluation Indices 4.2.1 The "Leader" standard evaluation indices for high-speed transmission wire extruders and cage winding equipment are divided into basic indices, core indices, and innovative indices. 4.2.2 Basic Indices 4.2.2.1 The basic indices of high-speed transmission wire extruders include screws, barrels, clearance between the screw and barrel, heating systems, and electrical safety protection. 4.2.2.2 The basic indices of cage winding equipment include specification requirements, precision of the winch, radial runout tolerance of the outer diameter of the winch roller, precision of the wire spool rack, safety requirements, and assembly requirements. 4.2.3 Core Indices 4.2.3.1 The core indices of high-speed transmission wire extruders include product eccentricity, temperature control precision, and energy-saving requirements of the whole machine; the core indices are divided into three levels, including advanced level, equivalent to a 5-star level in the enterprise standard ranking list; average level, equivalent to a 4-star level in the enterprise standard ranking list; and baseline level, equivalent to a 3-star level in the enterprise standard ranking list. 4.2.3.2 The core indices of cage winding equipment include precision of the winch, precision of the wire spool rack, a
