Roxtec has extended its range of cable seals with a new seal specifically for underground power cables serving structures including electricity substations and wind turbines.
Roxtec has developed new solutions for underground sealing against constant water pressure. The Roxtec UG™ multi-cable seals are ideal for power cables entering via foundations. The seals are designed to be resistant to constant as well as catastrophic water pressure and can be used to eliminate flooding and prevent humidity from damaging equipment in a wide range of applications in the power industry.
“Power transmission and distribution is a fast-growing area of work for Roxtec in the UK, due to the number of substations being built on flood plains and areas with high water tables. The Roxtec UG system can be used wherever there are underground cables being served by a cable trench. It has been developed as a specialist water tight seal.”
The UG seal is IP68-rated, 1 bar for catastrophic water pressure and 0.3 bar for constant water pressure. It can be used on trefoil single core cables. The system has been tested in Roxtec’s specialist test laboratory with retention tests of 1400N and 3300N depending on the product selected, meaning the system can handle the weight of many cables which is often the cause of failure in traditional sealants.
