EMI Challenges in Modern Hydrogen and Energy Storage Systems
Hydrogen electrolyzers, battery energy storage systems, and advanced power electronics operate in environments with high current densities, fast switching signals, and dense wiring networks.
These conditions make them particularly vulnerable to electromagnetic interference (EMI) and radio frequency interference (RFI), which can lead to:
Signal distortion and communication errors
Sensor misfires and control anomalies
Unexpected system downtime or reduced operational reliability
Traditional shielding methods—metal conduits, copper tapes, or foil wraps—often fail to provide adequate protection in such high-frequency, high-vibration, and high-temperature environments. Installation is cumbersome, flexibility is limited, and grounding is inconsistent, creating potential ground loops and long-term reliability issues.
Our Solution: Flexible Braided Shielding Sleeves with Grounding Strap
Our braided shielding sleeves are engineered to address these challenges and deliver complete electrical protection for critical systems:
360° EMI/RFI Shielding
High-conductivity tinned copper wires form a fully woven braid, effectively blocking electromagnetic noise and preventing signal interference.
Integrated Grounding Strap
Each sleeve includes a built-in grounding strap, ensuring consistent grounding, eliminating ground loops, and improving overall EMC performance.
Split Design for Easy Installation
The side-opening design allows retrofitting without disconnecting wires, simplifying maintenance and assembly in tight spaces, such as electrolyzer cabinets or battery racks.
Durable and Reliable
Resistant to corrosion, high temperatures, and mechanical stress, MJ sleeves maintain shielding effectiveness over long-term operation, even in harsh industrial environments.
