| Definition: | form of cross-bonding in which three consecutive elementary sections, termed “minor sections”, are taken to form a single unit, termed a “major section”
NOTE – The three shields are solidly bonded at both ends of a major section and may be earthed at these points. At the two intermediate positions, the cables are usually transposed and the shields are so interconnected that each continuous shield circuit through the major section occupies the same geometrical position in the cable formation. For long cable routes, there may be a number of major sections.
