Roxtec Sealing Systems: Electromagnetic Shielding
Roxtec Cable Seals
Electromagnetic Shielding
Roxtec cable seals are used in cable vaults, duct banks, electrical substations, trenches and M&E building services protecting low, medium and high voltage power systems against numerous external risk factors including fire, gas, water, cables, pressure, electrical, particles and blast.
Electromagnetic shielding
Why do you have to protect critical LV MV HV infrastructure equipment against EMI, IEMI, EMP and HEMP? How can you both seal and secure the electromagnetic shield? There are many questions regarding electromagnetic threats.
Roxtec are happy to be able to provide answers – and cable transit solutions.
Their skills and expertise enable the correct solution to be chosen that has electromagnetic shielding alongside fire, gas and water ingress certification.
What is EMI, IEMI, EMP and HEMP?
EMC refers to good electromagnetic compatibility.
Disturbances can be attributed to electronics like computers and mobile phones.as well as war or acts of terror. They can majorly affect electrical equipment and critical power supply to hospitals, banks and server halls, and a blackout can be very expensive.
- EMI – electromagnetic interference
- IEMI – intentional electromagnetic interference
- EMP – electromagnetic pulse
- HEMP – high altitude electromagnetic pulse
The Roxtec ES sealing system
The Roxtec ES sealing system provides an effective protection when used in shielded environments. It diverts conducted disturbances, shields against radiated disturbances and provides a mechanical and environmental protection against fire, gas, water, dust, dirt and rodents.
HEMP protection
Roxtec can help you protect equipment against the effects of HEMP, a high-altitude electromagnetic pulse caused by a nuclear weapon far above the surface of the earth. HEMP causes chaos through electromagnetic pulses. It makes transformers explode and can cause breakdown of the entire power grid.
Verifying shielding effectiveness
At the Roxtec test lab, we use shielded rooms, antennas, transmitters and receivers to verify the ability of our seals regarding attenuation of radiated interferences. The cable seals have undergone numerous shielding attenuation and transfer impedance tests.
