Wind Industry Profile of

Hauff-Technik Offshore-Sealing-System in The Windfair Newsletter

A60-proof IMO 754 (18) with medium-voltage/submarine- and offshore-hybrid cables

Electrical cabling in offshore wind farms require pressure-tight and fire-proof sealing solutions in steel container plantations. Not only numerous supplies of medium-voltage level of their respective turbine are brought together in central substation platforms but also the land connection of 150 kV high-voltage and fibre optical cables. With its individual high-quality seawater-resistant stainless steel constructions Hauff-Technik provides an ideal multiple socket piece within a few days. According to the particular cable arrangements and cable diameter the flange plate will be screwed vibration- and corrosion-resistant with a heat-resistant, halogen-free, uv- and oil-proofed flat sealing.

The precise round openings of the connecting pieces provide ideal prerequisites to ensure a gentle and permanently elastic sealing with custom-made seals. The permanently high rebound elasticity of the halogen-free rubber material is guaranteed by a highly quality stable grouting with seawater-resistant high-alloyed stainless steel plates. The materials withstand rough environmental conditions on the high seas with excellent seawater- and very good uv-resistance. Also in cases of emergency transformer oils are kept safe in insulating containers. Because the offshore-sealing-system is arranged as a material compound, the Hauff-Technik-System fulfill these highest requirements in a special way. Sealing and fire protection materials deliver independently of each other optimal best possible fulfillment of the different requirements without any compromises, as they usually have been built in highly filled composite elastomers until now.

Hauff-Technik Offshore-Sealing-System was proofed A60 according to IMO 754 (18) and will achieve a general GL-certification for all cables normally used with a proven occupancy rate of 40%. Cost-intensive and time-consuming certifications for each individual case are omitted in future.
