Roxtec UG Solutions - Cable Duct Seals For Underground Applications

Roxtec UG forms part of the range of cable duct seals from Roxtec and is designed for sealing cable ducts and entries in underground applications - this includes LV MV power cables ducted in trefoil arrangement supplying 11kV and 33kV substations.

Roxtec Cable Seals

Roxtec UG duct seals provide a long lasting cable seal against high pressure water ingress and is deal for use on underground cables entering through building, transformer or substation foundations.  

The following film includes UK site footage of test installations where water tables were problematic for the utility.

A number of different "traditional"  duct seals had all failed over time due to the challenge of installing the seals under "running water" situations.

Roxtec UG seals prevent flooded substations and the consequential power outages caused by sub-standard cable duct sealing.

Long Lasting, Excellent Protection

The Roxtec UG cable duct seal has been designed and developed to be used specifically in underground applications where damage caused by fire is unlikely.

The cable duct seals are constructed to be fully resistant to constant, high water pressure and can be used to eliminate flooding.

The innovative Roxtec knock-out sleeve is designed to be cast into the undergound foundation and provides capacity for expansions and future cable installations.

The cable sleeves are available in 3 different standard industry sizes and are designed to fit Roxtec UG seals and frames.

Each sleeve can be used in many different combinations and putting the pieces together is very simple.
