INTERFERENCE in switchgear cabinets, mainly caused by frequency converters, requires the use of shielded cables that are effectively connected to the ground of the switchgear cabinet.
The WAGO shield (screen) connecting system, Series 790 is available from NHP Electrical Engineering Products .
Four different types of shield (screen) clamping saddles for cables with a diameter of up to 40mm are available. The clamping saddles can be mounted quickly by means of a snap on mechanism.
A spring material forms part of the clamping saddle, preventing the braiding from being damaged, compensating any deformation in the braiding and ensuring the connection is unaffected by vibration.
The shield (screen) clamping system offers several mounting options, each of them allowing the clamping to be positioned very close to the unshielded part of the cable.
The system also acts as a partial strain relief.
