RFOU VFD EMC

Description

Offshore power VDF EMC

DESIGN

Conductor
Class 5 tinned copper, based on IEC 60228

Grounding conductor
The grounding conductor is divided into three conductors; the equivalent section of the three protective conductors together is approximately 50% of the section of the phase conductor.

Insulation
Halogen Free Ethylene propylene, type EPR according to IEC 60092-351.
The standard identification is the following:

3x + 3G

Brown + Black + Grey + Green/Yellow (3x) (from 6mm2 conductors)

Bedding
Halogen Free compound.

Screen
Copper-polyester tape helically placed over the bedding. The tape serves as a screen. Over the tape there is a tinned copper braid screen. The tape and the braid act as a double screen to cut out all of the electromagnetic interference. The screen has a cover of 100% and its total section is approximately 10% of one of the conductors.

Outer sheath
Mud resistant thermosetting compound, black colour, low smoke and halogen free, type SHF MUD.

APPLICATIONS

Our offshore power Variable Frequency Drive (VFD) cables have been designed for use in drive systems where variable frequency drives are used to protect equipment against the effects of electro-magnetic interference (EMI). A well as the appropriate screening the outer-sheath is based on IEC 60092-353 and NEK TS 606. Suitable for fixed installation.
