Telecom & Defense. MCB Cabins (EMP Proof) with RFI Doors.
EMP-proof MCB cabins with radio-frequency-interference sealed doors, delivered on trucks for field installation across nationwide telecom infrastructure. Turnkey enclosures for mission-critical switching and power distribution.
What made this hard.
- Attenuate EMP and RF from 10 kHz to 10 GHz.
- Preserve shielding integrity across door openings and cable entries.
- Ship pre-tested; drop into telecom sites without on-site retrofit.
- Deliver at telecom-programme cadence: multiple units per month.
How PES built it.
- Continuous copper mesh liner electrically bonded to the shell.
- Beryllium-copper finger-stock RFI gasketing on all door frames.
- Waveguide-below-cutoff cable entries for filtered penetrations.
- In-house shielding-effectiveness test bench before dispatch.
Numbers the customer measures us on.
