Take the finite length s buried cable as a research object and establish a physical analysis model with the theory of electromanetic field and FDTD .

To counteract the problem of a large quantity of cables damaged by termites in the world each year,this paper emphatically analyzes the reasons of termites damaging the buried cables,and describes the merits and defects of several main methods to control termites,including ecological method,using anti-termite cables,poisoning the soil,and supervisory trapping and killing.

The method of using the earth resistance reflector to determine the electric leakage position of the buried cable;

Design of Underground Cable State Monitor

Through techno-economic analysis of overhead lines and underground cables in urban power network,their differences in electric performance,rated current and losses,reactive power and transmission capacity,etc.

The mechanism of insulation fault in underground cable and the principle of simultaneous measure- ment of temperature and strain distribution utilizing Brillouin scattering in optical fiber are analyzed in this paper.

Based on the analysis of sand wave topographic features and the available cable burial techniques,the submarine cable burial and construction techniques in the sand wave area are introduced in terms of burial equipment and construction mode.
