ALVL low voltage limiters
Information
Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

Results per page:
ALVL low voltage limiters are advanced surge protection devices designed to protect structural elements in traction networks powered by direct current (DC) and alternating current (AC). Their main purpose is to protect people from dangerous touch voltage that may occur as a result of a lightning strike or a catenary failure.
Application
ALVL arresters are designed for:
-
Protecting structural elements in catenaries powered by direct and alternating current,
-
Protecting people from dangerous touch voltage in the event of a catenary failure,
-
Indoor and outdoor installations, including in the pantograph area (current collector) and on supporting mast structures.
Benefits
-
Effective protection against Overvoltage: ALVL arresters effectively reduce the risk of electric shock due to lightning surges or catenary failures.
-
Maintenance-free operation: Thanks to the use of modern technologies, these devices do not require regular maintenance, which reduces maintenance costs.
-
High weather resistance: The silicone rubber housing provides excellent resistance to external factors such as moisture, UV radiation, and pollution.
-
Wide range of applications: Thanks to the various models, ALVL arresters can be used in both indoor and outdoor installations, adapting to the specific needs of the user.
