When traditional methods were not enough to guarantee watertightness, Sarpel Ingeniería (an Energy Solar Tech Group company) specified Roxtec modular-based multi-cable and pipe seals. It was a successful decision – ensuring complete tightness and enabling huge cost savings.
“Roxtec solutions have allowed us to ensure watertightness in our substations —something we could not achieve with traditional methods like foams or resins,” company representatives explain. “Their ease of installation and ability to be modified in the future have saved us time and costs. Roxtec is a reliable and efficient solution.”
Flexible sealing solutions
Sarpel Ingeniería (an Energy Solar Tech Group company) is working for numerous major players within renewable energy. The company is using primarily Roxtec UG™ (underground) seals to ensure tight entries for medium-voltage, low-voltage, and grounding cables as well as for fiber optic cables.
The leakage issues they had to overcome in different substations were due to poor sealing with foams, resins, or concrete with drainage. Sarpel Ingeniería (an Energy Solar Tech Group company) recommended Roxtec seals to be able to meet the requirements and guarantee watertightness.
Saving up to €6,000 per project
The cost savings from avoiding leakage claims range from €3,000 to €6,000 per project, since in the event of a leak, sealing must be done from the inside with resin. All filtered material must be drained, and damage repaired. Roxtec solutions can be opened and modified, unlike others that require breaking and replacement with new material.
Long-term multi-hazard protection
Company representatives appreciate that the Roxtec sealing system simplifies for changes and upgrades. They also highlight the efficient protection against rodents and fire:
“This solution ensures that future users of the installation can easily adapt or modify the entries while still maintaining full compliance with Roxtec specifications and guarantees for reliable sealing performance. This prevents any sealing deficiencies and eliminates issues for the customer throughout the entire lifecycle of the installation. It is also important to highlight that the seal does far more than protect against water ingress. With Roxtec’s cable sealing accessories, it also safeguards against rodent intrusion and even prevents the spread of fire.”
Roxtec is a reliable and efficient solution.
