9、ing and joining conductors of insulated electric cables, having compacted stranded, or uncompacted stranded conductors in the size range 10 mm to 630 mm. 1.2 This standard covers lugs and ferrules for attaching to the conductor by compression, using special tools. Soldered lugs are not included. 1.3
10、 This standard does not apply to compression joints on overhead conductors, which are designed to withstand high tensile forces, or to pre-insulated lugs. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this standard.
11、All standards are subject to revision, and since any reference to a standard is deemed to be a reference to the latest edition of that standard, parties to agreements based on this standard are encouraged to take steps to ensure the use of the most recent editions of the standards indicated below.

17、the intended application. The test is of such a nature that, after it has been successfully completed, it need not be repeated unless changes are made to the materials or design that might affect its performance 4 General requirements 4.1 Sizing Lugs and ferrules made to this standard shall be desig
18、ned to fit a specific conductor size and shall be marked with a number to indicate the conductor size in square millimetres. Where, on the larger sizes, significant differences exist in the diameters of compacted and uncompacted conductors, two sizes of connector shall be included, the code letters
19、XL identifying the lug or ferrule intended for use on compacted conductors. 4.2 Material Lugs and ferrules made to this part of the standard shall be of electrolytic grade copper, and may be bare or tinned. 4.3 Finish The surface finish as visually examined according to 6.1, shall be clean and be fr
20、ee of all defects such as burrs, cracks, rolled seams, blisters, twists, press and chatter marks. The faces of the palms of the lugs shall be flat and smooth. Fixing holes shall be free of burrs. The entry to the barrel of the lug or ferrule shall be profiled to facilitate entry of the conductor eit

Ferrules shall be similarly marked in the centre or at on
22、e end. If so required for the crimping procedure, the barrels of lugs and ferrules shall be marked to indicate the correct crimping positions, and if necessary also, the correct sequence of crimping (see 6.1).SANS 1803-1:2009 Edition 1.1 5 5 Dimensions 5.1 Lugs 5.1.1 Special requirements Lugs to be
