Definition - What does Cable Locators mean?
Cable locators can be defined as devices that are used to detect the presence of buried cables. Locating cables is a necessary step before conducting any kind of excavation to ensure that buried cables are not damaged. Locating cables is especially important in trenchless technology because of the sub-surface nature of excavation and is a part of the geotechnical investigation carried out for trenchless projects.
Trenchlesspedia explains Cable Locators
Cables are used to supply electricity and telecommunication services and damaging these lines can not only disrupt services, it can also be dangerous to human life. Cable locators have an internal antenna that picks up the magnetic field in its receiver. The magnetic field may be artificially generated using a transmitter or picked up from magnetic waves generated by cables carrying current.
They are classed as cable avoidance tools which are used to locate basic services and general area of utility location or professional locators which are used for locating utilities in congested areas, deep service location, location of large pipelines and long distance location.
