This part of IEC 61952 is applicable to composite line post insulators for AC overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to line post insulators of similar design used in substations or on electric traction lines. This document applies to line post insulators of composite type@ generally with metallic couplings@ with and without a base plate. It also applies to such insulators when used in complex structures. It does not apply to hollow insulators adapted for use as line post insulators. The object of this document is to specify the main dimensions of the couplings to be used on the composite line post insulators in order to permit the assembly of insulators or fittings supplied by different manufacturers and to allow@ whenever practical@ interchangeability with existing installations. It also specifies a standard designation system for composite line post insulators.

ASTM B400/B400M-19 紧凑型圆形同心绞捻铝1350导体的标准规范

1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 ([n ]hard), 1350-H14 or -H24 (1⁄2 hard) and 1350-H142 or -H242 (1⁄2 hard) bare compact-round concentric-lay-stranded conductors made from round or shaped wires for use as uninsulated electrical conductors or in covered or insulated electrical conductors. These conductors shall be composed of a central core surrounded by one or more roller or die compacted layers of helically applied wires (Explanatory Note 1 and Note 2). 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. NOTE 1—Prior to 1975, aluminum 1350 was designated as EC aluminum. NOTE 2—The aluminum and temper designations conform to ANSI Standard H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Compact Round Concentric-Lay-Stranded Aluminum 1350 Conductors

ASTM B778-19 紧凑型同心绞合铝导线（AAC/TW）的标准规范

1.1 This specification covers shaped wire compact concentric-lay-stranded aluminum conductor (AAC/TW) and its component wires for use as overhead electrical conductors (Explanatory Note 1 and Note 2). 1.2 The values stated in inch-pound units are to be regarded as the standard with the exception of temperature and resistivity. The SI equivalents of inch-pound units may be approximate. NOTE 1—AAC/TW is designed to increase the aluminum area for a given diameter of conductor by the use of trapezoidally shaped wires (TW). The conductors consist of a central core of one round aluminum wire or a seven-strand compact round core surrounded by two or more layers of trapezoidal aluminum 1350-H19 wires. For the purposes of this specification, the sizes listed are tabulated on the basis of the finished conductor having an area equal to that of specific sizes of standard AAC (Table 1) or in fixed diameter increments (Table 2) so as to facilitate conductor selection. NOTE 2—The aluminum and temper designations conform to ANSI Standard H 35.1. Aluminum 1350 corresponds to Unified Numbering System (UNS) A91350 in accordance with Practice E527. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 General 1.1 RO.1 General (ncpt) This Part 2-24 gives the requirements for planning, design and construction of overhead electrical lines with nominal voltages exceeding A.C. 1 kV operating at 50 Hz frequency. The present Part 2-24 is not applicable for existing overhead electrical lines unless specifically required by Project Specification. The power installations of overhead lines, that are in different stages of design or construction, can be finalised in conformity with the standards in force at project beginning. For the application of this standard for specific requirements relaring to modernization, increasing safety and transport capacity of existing overhead lines, reference shall be specified in the Project Specification. At the same time, the correlation between relevant regulations and associated standards shall be established in the Project Specifications. The extension of existing electrical lines is considered as new overhead lines, except the junction points that shall be detailed in the Project Specifications. 1.2 Field of application 1.2 RO.1 Overhead electrical lines with insulated conductors (ncpt) This Part 2-24 is applicable for the design and construction of overhead electrical lines with insulated conductors where the internal and external clearances can be smaller than those specified in Part 1 (SR EN 50341-1:2013).

1   SCOPE 1.1   General (snc) EE.1 Application to new lines In Estonia the standard EN 50341‑1 (Part 1) can only be applied using this NNA (EN 50341‑2‑20) containing National Normative Aspects for Estonia. This Part 2-20 applies to all new overhead electric lines with nominal system voltages exceeding AC 1 kV and also for low voltage (below 1 kV AC) overhead lines performed by aerial cables. The requirements of the structural design are applicable also for DC overhead lines, where the electrical requirements are given in the Project Specification. (ncpt) EE.2 “New overhead line” A “new overhead line” means a completely new line between two points, A and B. A new branch line of the existing power line should be considered as a new power line including the junction support. Specific requirements for junction support should be defined with the Project Specification.
