Hauff Technik
Hauff Technik are leading manufacturers of sealing systems for cables, pipes and building entries. They have been protecting buildings from penetrating water, gas, fire, dirt and vermin for the past 60 years. Specialising in sealing cable entries for secondary substations, Hauff Technik’s innovations help protect and set standards in the energy supply sector.
Hauff Technik’s new assembly challenge they pit the cold shrink-fit method against the heat shrink-fit method.
Both variants have their benefits. The cold shrink sleeve can be assembled without the need for tools. The cold shrink-fit method can only be used outside of buildings, however the sleeve remains permanently elastic.
The hot shrink-fit method can be used on the outside or inside of buildings. A hot air gun or gas burner is required for assembly. The heat shrink sleeve remains rigid, but is gastight and waterright up to 2.5 bar.
