Roxtec - Flexible Cable and Pipe Seal Manufacturing for the Rail Industry

Roxtec is one of the world-leading manufacturers of modular-based cable and pipe penetration seals for the railway industry. Roxtec solutions are used on all kinds of trains and light rail vehicles to ensure passenger safety and long-term operational reliability. The sealing system is also used in signaling and trackside equipment.

The Roxtec system protects life, assets and sensitive equipment. It also provides built-in spare capacity for upgrades, which is beneficial when it comes to staying competitive during the entire lifecycle of the train.

Cable and pipe-sealing technology

Roxtec was founded in Sweden in 1990 with the invention of Multidiameter™, a solution for adaptability to cables and pipes of different sizes based on sealing modules with removable layers. The technology simplifies design, speeds up installation work, and minimises the need for stock, materials and logistics. It also allows routing of pre-terminated cables.

Modular mechanical sealing technology

The Roxtec system is a mechanical solution, suitable for many applications and for multiple or single pipe penetrations. With six basic modules, it is possible to seal cables and pipes from 3.5mm to 99mm in diameter. The modules are inserted around cables or pipes in frames that are welded or bolted into the structure. The system is sealed with a separate or integrated compression unit.

Sealing of penetrating cables and pipes

Roxtec seals are used for all types of cables and pipes passing through partition walls, roofs and floors, and through different structures in the train. It is used in the driver's cabin, the engine room and in switchboard panels as well as for traction motors and converters / inverters. Other applications include installations for AC systems and pantographs.

The seals are used in cabinets and enclosures, and are available in versions with Ex and EMC performance. Area efficiency and reduced overall weight are benefits appreciated by users.

Roxtec seals provide superior protection against risks caused by fire, smoke, water, rodents, strain and shock-waves. The system is designed for cable management, clamping and retention of cable and pipes. The smooth yet firm Roxylon™ rubber absorbs vibrations and contributes to safe and comfortable operations.

Tested cable and pipe penetration seals

Roxtec products are tested according to the European standards CEN/TS 45545 part two and three, and several other test standards such as ASTM E662, UL 94, the German standard DIN 5510-2 and the French standard NFF 16-101/-102. The Roxtec sealing system is also approved and certified for use in hazardous and potentially explosive environments.

The main benefits of Roxtec include:

• Roxtec offers fast delivery and local technical support around the world: it is present worldwide to ensure product availability. Standardising with Roxtec secures operation wherever the train ends up.
• Easy planning, design and installation: thanks to Multidiameter™ and the Roxtec transit manager software tool, it is possible to make a complex design in a few minutes, with full cable control and transit detail overview. This improves project and cost management
• Built-in spare capacity for future needs and regulations: Multidiameter™ makes it possible to add cables and pipes of different sizes without any need for additional modules and the seal can be opened repeatedly without jeopardising integrity. Using Roxtec is a way of making improvement work secure and cost-effective and to reduce the total cost of ownership
