Roxtec sealing solutions were selected for use in the Dulles Corridor Metrorail Project in Washington, D.C

Report from Heavy Railway project at Dulles Metrorail

Roxtec sealing solutions were selected for use in the Dulles Corridor Metrorail Project in Washington, D.C in order to secure power supply, prevent water from damaging equipment, and minimize danger in case of fire.

The Dulles project team looked for an alternative sealing solution to the one they originally used, as it required exact knowledge about the size of all cables and conduits. They also did not want to use two different seals for the cables and the conduits, or use a compound containing lead.

Discovering Roxtec: Offered the right solution

Fortunately, Rich Farland, Senior Traction Power Engineer of design-build contractor Dulles Transit Partners had heard about Roxtec at a “lunch and learn” event and at a tradeshow. “I’m glad I came across Roxtec. The products work very well for us, as they can accommodate various sizes of cable. It makes it easy to do the design work and to handle changes in the field.”

As a result, Roxtec was specified for sealing of conduits and cables in conduits by Rich Farland for the Dulles Project.

Five Key Reasons for Selection of Roxtec For The Dulles Metro Project

1-Provided flexibility

Since Roxtec seals are adaptable to cables of different sizes and designed to fit various materials, the choice turned out to be perfect. The seals are used for fiberglass conduits, power cables and shielded cables as well as for handling at least ten different cable sizes and four sizes of conduit.

2-Numerous applications

Cables entering the substations and gap breaker stations via conduits are sealed from water by Roxtec. In certain areas, such as roof applications, Roxtec covers the special requirement for both water-tightness and a 3-hour fire rating. Roxtec is also used in the duct banks leading power cables to the contact rail. All seals on the wayside are there to keep water out of the conduits.

3-Power to the train

In the concrete structures supporting many miles of elevated track, some Roxtec seals hold the large power cables in place while others secure water-tightness and the power supply.

4-Speeding up the work

Where the new line meets the existing one, the work had to be done quickly without any digging. The solution was to let cables come up through a cast surface trench and seal them with Roxtec.

5-Changes made easy

If a cable is damaged and you have used shrink tubing, it can be difficult and time-consuming to remove. Roxtec eliminates shrink tubing; you just loosen up a few bolts and take it apart in a secure way. Roxtec seals also offer built-in spare capacity in order to simplify adding and removing cables in the future.
