Roxtec Sealing Cables & Pipes In The Rail Industry

Sealing Cables.

Reliable Cable & Pipe Sealing In The Rail Industry.

The ingress, migration, spread and attack of water, gas, fire, smoke, rodents, dust and EMI are the main risks associated with cable and pipe service penetrations on rail infrastructure.

Roxtec, the leading manufacturer of cable and pipe sealing solutions, protects vulnerable assets and ensures their reliable operation with safe and certified cable sealing systems.

Roxtec have recently designed and manufactured heavy-duty cable sealing solutions for Network Rail’s London Bridge railway station substation.

The bespoke cable and pipe transit frames which, at 218kg each, are the heaviest frames Roxtec has ever produced for the UK, are specifically designed for the flagship rail project.

Together with the Roxtec cable and pipe sealing modules and compression units they will protect against the threat of water ingress, condensation, fire and rodents.

Managing Director of Roxtec, Graham O’Hare said the rail substation project, part of the multi-billion pound Thameslink Programme, required all of Roxtec’s engineering experience and expertise.

"Network Rail commissioned us to seal cables entering the substation from ground level inside a trackside riser above a switch room,” he said.

"We had to ensure that the cables feeding from the switchgear substation to the tracks were properly sealed and protected against multiple hazards."

"To achieve this we designed and manufactured customised transit frames to seal the high voltage cables. The cable transit frames, which had to both protect the 53mm diameter cables and provide ultra-rigidity for the tight radius bend, were then cast into poured concrete because of their weight. As a risk of condensation was also identified, each frame was sealed at both ends.

"The transit frames measured 1.5m in depth and were designed with puddle flanges and a special arch shaped flange to match the curvature of the existing substation roof.”

Roxtec’s cable seal solutions provide water ingress protection which exceeds the highest IP rating, a one-hour fire rating and vibration and pull-out resistance.

Crucially for the rail industry, they also have a long-life expectancy of up to 30 years.

He added: "Our engineers were heavily involved during the design phase of the project and provided full technical support throughout. We also provided installation training ahead of the work and then sent a Roxtec representative to oversee the weekend installation.

“As ever with Roxtec cable sealing solutions, we ensured that space was created to enable future cable upgrades can be made with the minimum of disruption.”

CPDMr O’Hare said Roxtec was able to win the Network Rail contract after showcasing its high-level of expertise during a rail industry Continuing Professional Development (CPD) seminar.
