ISO 8205-2021 pdf download.Resistance welding equipment- Water-cooled secondary connection cables. This document gives specifications for single- and double-conductor secondary connection cables used for resistance welding and allied processes. These specifications include requirements for electrical, mechanical and cooling characteristics of the cables and their test procedures. 2 Normative references There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: — ISO Online browsing platform: available at https://www.iso.org/obp — IEC Electropedia: available at http://www.eIectropediaorg/ 3.1 double-conductor connection cable cable comprising two conductors providing an electrical link between the secondary terminals of a welding transformer and the welding set (manual or robotized guns) and designed so as to have as low an electrical reactance as possible 3.2 single-conductor connection cable cable comprising one conductor providing an electrical link between the secondary terminals of a welding transformer and the welding set (manual or robotized guns) 4 Classification 4.1 Form of the end lugs Double-conductor water-cooled connection cables are classified into two types. A-I and A-2, in accordance with the form of the end Jugs (see 5.1.3). Single-conductor water-cooled connection cables are classified into three types, C-i. C-2 and D, in accordance with the form of the end Jugs (see £2.3). 4.2 Resistance and reactance Double-conductor, water cooled connection cables are classified into two types, A-i and A-2, with power factor cosp  0,95 as shown in Figur1. 5 Dimensions 5.1 Double conductor connection cables 5.1.1 Cross-sectional area The effective cross-sectional area of copper per conductor shall be one of the following: 100 mm2 一150 mm2 一160 mm2 一200 mm2 一250 mm2 一315 mm2 5.1.2 Length The length, L, of the cable shall be one of the fllowing (non-preferred values are given in parentheses). The length shall have a tolerance + %: 一1 000 mm 一1 200 mm 一1250mm-(1500mm) 一1600mm-(1800mm) 一2000mm-(2240mm) 一2400mm 一2500mm-(2800mm) 一3000mm 3 150 mm 一3500mm-(3550mm) 4 000 mm 5.1.3 End lugs The end lugs shall have the dimensions given in Figure 1 and Table 1.ISO 8205 pdf download.
