Mulching high-voltage transmission and gas supply lines

Mulching high-voltage transmission and gas supply lines

In order to meet their legal duty to maintain safety and prevent damage or irregularities in the electric power supply, energy providers must prune back or have pruned back the trees and shrubs that grow into the protection zone of the overhead lines. The concept the power grid operator hereby stipulates that the vegetation must not grow closer than five metres to the lines. High-voltage transmission lines must therefore continuously be kept free from grass, undergrowth and shrubs. Overhanding branches must also be cut back constantly.

Because of the sheer size of the infrastructure (for instance, about 10 % of the 12,500 km of overhead transmission lines of the grid operating company RWE-Net run through woods), this work must be completed quickly and efficiently!

Efficient line care minimises the maintenance costs of overhead lines and ensures their reliable failure-free operation. In the sparsely vegetated time between October and March, forest offices, nature conservation associations or qualified service providers are therefore busy cutting the overhead lines free.

This is to be done with trade-association-approved methods.

With our radio-controlled equipment, legally stipulated minimum clearances are immaterial. Operator can always be far enough – this reduces switch-off times to a minimum.
