Our Service


Switchgears are elementary components for the distribution of electrical energy for both, industrial and private sectors. They are several decades in use and must occasionally be adjusted to changed operational conditions.

GSB supports you by expansion, reconstruction or modification of your plants. We offer individual solutions and enhance your existing systems with additional cubicles.

GSB has many years of experience in different kinds of power systems. We supply suitable measuring transformers and meters for you. The adaptation or replacement of circuit breakers or disconnectors is done independent of manufacturer on the basis of the right technical and economical solution. This guarantees high quality results and an optimized price-performance ratio.
