Single-bonded cable

Grounding of a cable, (a) Single-bonded cable and (b) solidly bonded cable.

Single-point bonding as part of a cross-bonded cable. 

Section 3.2.1 addressed the impedance and admittance of a single-phase cable. This section addresses the impedance and admittance of a cross-bonded three-phase cable and how 6x6 impedance and admittance matrices can be reduced to 4 x 4 matrices. 

A key factor in the design and choice of earth continuity conductors, e.g. cable armouring, bonding straps, and fault current protective devices is the earth loop impedance . This is especially the case for solidly earthed low voltage systems, whether they be three-phase, single-phase or even direct current systems. 

The chemistry of polymers gives, as must by now be apparent, wide scope for developing materials with new and useful properties. In electrics they now do far more than just insulate cables. Polymeric conductors, which have already been in use for some years, are among the most remarkable. Chains with conjugated backbones— those with alternating single and double bonds, in which the electron doud extends over the whole...
