One negative consequence of “modern technology” is an increased vulnerability to different types of electromagnetic disturbances. Disruptive low-frequency magnetic fields from switchgear, transformers, etc. often leads to costly downtime and production stops. Low-frequency magnetic fields can also have a negative impact on the working environment and human health and safety.
Disruptive low-frequency magnetic fields are often reduced on-site by encapsulating the source of the interference. For maximum reduction effect, shielding should be done as close to the source of disturbance as possible. We supply both fully assembled solutions and components for self-assembly.
Solutions based on traditional welding techniques often lead to problems:
• Cause interference on sensitive equipment nearby
• Welding is subject to the requirements for hot work
• Arc monitors can be triggered on switchgear, etc.
• Welding is not permitted in some settings
• Welding has a negative impact on the environment
• Results are dependent on the skill of the welder and can therefore vary from one occasion to the next.
The press wedge system offers a strong alternative to welded encapsulation structures.
The system is built around only three types of components - extruded aluminium profiles, aluminium press wedges and aluminium sheet (5 mm, type 4007-14 / EN 1050A-14). The modules are easily built into existing environments.
The system is verifiable and is offered with a wide range of application possibilities. It can also be supplemented later on. The turnkey solution is eco-friendly and aesthetically appealing. The press wedge system is also attractive from an economic standpoint in comparison with welded systems.
With the press wedge system, you avoid difficulties associated with welding solutions:
• Easy and fast assembly directly in existing environments
• Cleaner handling. Sanitation/decontamination can be avoided entirely
• No special permit required
• No disruption to surroundings during installation. Activities in surrounding environments can continue without disruption.
In measurements conducted by the Swedish Rail Association, Banverket, the press wedge system was compared with a traditional welded solution. The results show that the reduction effect of the press wedge system is fully comparable with systems with welded joints.
