About Back / Earth Fill Compound
A
BFC (Back Fill Compound) is a specialized, highly conductive moisture-retentive material used to optimize
electrical grounding systems. It is packed in bags (typically 25kg) and poured into the pit around an earthing electrode to permanently lower soil resistivity.
High-Performance Lightning ProtectionWith its Early Streamer Emission technology, the BFC Bag Compound provides a proactive solution for safeguarding buildings and towers. Its exceptionally fast response time of under 60 microseconds offers superior defense against direct strikes, maintaining safety and minimizing damage risks.
Rugged Design for Outdoor UseManufactured from stainless steel, the BFC Bag Compound endures challenging weather and environments. Its substantial 700 mm height and 5.5 kg weight contribute to its stability and performance, making it a dependable choice for rooftop or ground installations.
FAQ's of BFC Bag Compound:
Q: How does the BFC Bag Compound provide lightning protection?
A: The BFC Bag Compound uses Early Streamer Emission (ESE) technology to detect and intercept lightning discharges before they strike structures. By emitting an upward leader earlier than conventional air terminals, it attracts and safely channels the lightning current to the ground, minimizing damage.
Q: What types of structures are suitable for installing the BFC Bag Compound?
A: This lightning protection device is ideal for outdoor protection of buildings and towers, especially high-value or mission-critical sites. It can be installed on rooftops or on the ground with a mast, providing versatile coverage for a variety of architectural designs.
Q: When should the BFC Bag Compound be installed for optimal performance?
A: It is best to install the BFC Bag Compound during new construction phases or as part of an overall lightning protection upgrade. Installation prior to lightning season ensures continuous protection against surge and direct strikes.
Q: Where should the BFC Bag Compound be mounted for maximum effectiveness?
A: For maximum protection, it should be mounted at the highest point of the building, typically on the roof or on a mast. Positioning at elevated points ensures the air terminal can offer a broad protection radius around the structure.
Q: What is the installation process for the BFC Bag Compound?
A: Installation involves securely fixing the air terminal to the roof or ground mast, establishing a reliable earth connection, and ensuring compliance with Class I lightning protection standards. Professional installation is recommended for safety and performance.
Q: How is the BFC Bag Compound maintained after installation?
A: Periodic inspections and standard electrical checks are advised to ensure the device remains in optimal condition. Its robust stainless steel build minimizes maintenance needs, but verifying electrical continuity and secure mounting enhances long-term reliability.
Q: What are the benefits of using a BFC Bag Compound air terminal?
A: Key benefits include a rapid response time for early interception of lightning, high-level protection for outdoor structures, robust durability, and compliance with the highest protection class. This leads to reduced downtime, lower maintenance costs, and enhanced safety for critical infrastructure.
