Power generation and substations

1Turbines and generator sets

The problem

Gas and steam turbines and generator sets turn non-stop: vibration, structural fatigue and a risk of misalignment.

What we fit

All-metal isolators, double springs with restraint or a floating slab under the machine, depending on its weight and speed.

Typical choice

Vibration mounts 954202-95420350–7,000 kg · 11–22 HzAnti-vibration floating slab1–4.5 HzDouble springs with retention80–1,460 kg · 7–9 Hz

The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.

2Exhausts and hot pipework

The problem

Turbine exhausts and gas ducts work at hundreds of degrees and expand: rubber cannot cope and rigid supports fatigue.

What we fit

Telescopic supports and all-metal isolators that isolate vibration and let the pipe expand.

Typical choice

S501 exhaust pipe vibration mount20–7,000 kg · 10–25 HzAnti-vibration metal cushion0–3,000 kg · 10–35 Hz

The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.

3Transformers and substation

The problem

A transformer hums continuously at 100 Hz. The hum passes through the floor to the control room and nearby buildings.

What we fit

A floating slab under the transformer or transformer mounts under its base, as in Endesa's substations.

Typical choice

Anti-vibration floating slab1–4.5 HzSpring isolator390–8,760 kg · 3–9 Hz

Proven in power plants and substations: Endesa (2011–2023), about 200 floating slabs for transformers.

The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.

4Switchboards and control rooms

The problem

Switchboards, UPS units and control equipment must keep working after an earthquake too, above all in nuclear power plants.

What we fit

Qualified seismic plinths (IEEE 344, as at Krško) and isolators for containers and equipment rooms.

Typical choice

Non-Raised Floor Plinth, seismic plinth for racks100–1,500 kg · 4–5 HzContainer Pad Seismic Vibration Isolator100–10,000 kg · 3–9 Hz

The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.

5Pumps and pumping stations

The problem

Feed, circulation or crude-oil pumps make the ground and the pipework of the whole plant vibrate.

What we fit

A floating slab under the whole pumping station or restrained isolators under each pump.

Typical choice

Anti-vibration floating slab1–4.5 HzMachine levelling feet25–7,000 kg · 15 HzEqual-frequency vibration mount4–3,125 kg · 2–8 HzDouble springs with retention80–1,460 kg · 7–9 Hz

The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.

6Cooling

The problem

Chillers, cooling towers and heat exchangers have fans and compressors that vibrate on the structure.

What we fit

Double springs with restraint, which isolate the equipment and hold it in wind or earthquakes.

Typical choice

Spring isolator390–8,760 kg · 3–9 HzDouble springs with retention80–1,460 kg · 7–9 Hz

The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
