415 / 417 MV Switch


FPS Swivels

The Model 415 medium voltage (MV) switch is designed to connect one three phase circuit to one of two others, at up to 24 kV, using single or multicore MV power cables. Its primary purpose is to select one of two subsea cables or swivel circuits or for use as a grounding device. This is a no-load switch, so circuits must be isolated before switching. The Model 417 is rated 36 kV.

There is sufficient space inside the switch to allow for MV cable termination and routing of large cables. There are facilities for connection of cable ground conductors and ground straps from the stress control sleeves.

The switch is certified as a flameproof (Ex d) enclosure. Ingress protection is IP66 / IP68. For power cables that include optical fibers, a fiber breakout facility is available.

All Focal 400 Series products are intended for use in Floating Production Systems (FPS). They are well suited for any application requiring a product that can withstand harsh marine conditions or require long life with minimal maintenance intervals. Designed and manufactured in our ISO 9001 facility under our project management system, products have a two year warranty and are provided with a complete document package.
