Electricity, transmission technologies and international regulation of the entire system
Electricity, transmission technologies and international regulation of the entire system
With the development of technologies, the number of materials and methods of their application is increasing, such industries as energy are developing, which are directly related to electricity and its use, optimization of processes and increasing the productivity of activities carried out. Despite the fact that the emphasis of modern innovations is on transmitting information and, if possible, other elements over long distances with minimal use of additional devices, in this case we are talking about wires and their use, in everyday life it is impossible to underestimate their role. That is why international standards regulating their production and operation are still among the most in demand. Today we will acquaint you with the latest updates in the field of international standardization, namely with documents that may be useful to you in building a clear scientific technological base and a safely functioning system.
Specifications for particular types of winding wires - Part 0-8: General requirements - Polyester glass-fibre wound unvarnished and fused, or resin or varnish impregnated, bare or enamelled rectangular copper wire
Each document and international standard has both detailed specifications and generalized rules for the entire industry. One example of a common document is IEC 60317-0-8: 2019.
This document is available as IEC 60317-0-8:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60317-0-8:2019 specifies the general requirements of polyester glass-fibre wound fused, unvarnished, or resin or varnish impregnated bare, or grade 1 or grade 2 or enamelled rectangular copper winding wires.
The range of nominal conductor dimensions is given in 4.1 and in the relevant specification sheet. This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - revision to the title of the standard indicating that the glass fibre covering is fused and unvarnished; - revision to subclause 3.2 adding winding wire requirements for the fibrous covering and a list of covering classifications; - revision to subclause 3.3 requirements for appearance; - revision to subclause 8.2, adherence test requirements.
Since this standard changes over time due to innovative development and adapts to changes, we recommend that you follow its updates if your field of activity fits the above characteristics.
Specifications for particular types of winding wires - Part 12: Polyvinyl acetal enamelled round copper wire, class 120
In addition to generalized standards, there are also documents that have an extended and detailed description of the technical aspects introduced into production processes when using certain devices, in this case, wires. One of the most key standards of this type is IEC 60317-12: 2020.
This standard is available as IEC 60317-12:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60317-12:2020 specifies the requirements of enamelled round copper winding wires of class 120 with a sole coating based on polyvinyl acetal or polyvinyl formal resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements.
NOTE 1 A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics.
NOTE 2 Polyvinyl acetal is a general name for a family of thermoplastic vinyl resins produced by the condensation of polyvinyl alcohol with an aldehyde. Examples are polyvinyl acetal, polyvinyl formal and polyvinyl butyral.

The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This fourth edition of IEC 60317-12 cancels and replaces the third edition published in 2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition: - modification of the Scope; - addition of reference to transformer oil resistance test method in Clause 20.
This document has undergone changes and transformations in different years and if you are using the international standard of previous years, we insist that you read the latest updates. After all, they will give you a clearer understanding of which stage of your production requires modernization and implementation of changes.
Due to the fact that many standards have absolutely similar parts and additions to each other, a situation often arises when, when selecting the necessary document, the specialists of your organization may be misled due to the fact that even the technical characteristics may be similar. Despite this, each document contains a distinctive feature by which it is possible to distinguish both the scope of possible application of this document and the technical features. One of the striking examples in which such trends can be considered are the standards EN IEC 60317-17: 2020 and EN IEC 60317-18: 2020.
