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.

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
