Underground cable laying — Proposal to lay power cable and OFC in one trench

The Objective of this paper is to workout and highlight the possibilities to operate an AC Power cable and Optical Fibre Cable (OFC) by laying both in one trench. This paper has studied the electrostatic, magnetic and thermal parameters associated with the above proposal. Mathematical equations, derivations supporting the claim have been presented. At the end, simulation tests were conducted by incorporating the obtained mathematical parameters into simulated environment. Beneficiaries of this proposal range from industry consumer(s), service providing companies, smart grids and the general public. Benefits could include distribution automation, economic aspect, reduced space requirement, reduced manpower and reduced road digging work. However, experimental tests to conform the proposal claims, developing standards for installation and operational purpose etc., all inspire us to work further on this proposal.
