Stationary and portable earthing lances
Earthing of high voltage conductors with earthing lances
Earthing and short-circuiting is a major element in a series of safety rules for work on or in the vicinity of electrical installations.In substations, earthing lances form the short circuit-proof connection between high voltage conductor (bus bar or other types of conductor) and the earthing system.
Benefit from our long-term experience and competence
For more than 30 years we plan, project, and produce stationary and portable earthing lances. Benefit from our long-term experience and competence resulting from successful realisation of a multitude of worldwide earthing lances projects. We provide expert consultation and will work on a customised solution in cooperation with you.
Portable or stationary
Both systems are designed for a maximum short circuit load of 80 kA / 0.5 s and a peak load of 200 kA.Usually portable earthing lances can be used up to a conductor height of approximately 8 m.
For conductor heights above 8 m, stationary earthing lances apply. These can be used with little effort for conductor heights up to 12 m.
