Introduction:
Beckercom’s innovative leaky feeder system revolutionizes communication in mines, fostering safety and productivity. This system enables miners to communicate seamlessly using standard two-way commercial radios, reaching every corner of the mine or tunnel. Additionally, the leaky feeder allows monitoring and control of electrical equipment, enhancing overall operational efficiency.
- Leaky Feeder System:
Beckercom’s leaky feeder system, when paired with the Becker I.S. Portable two-way radio, establishes two-way communication throughout the mine. Leaky feeder antenna cables transmit signals from the surface Head End, covering extensive underground travelways. This ensures effective communication and signal retransmission over kilometers.
- Head End Unit:
The Head End Unit consolidates up to sixteen channels, facilitating voice or data communication. Channels are allocated for various purposes, including general chat, production, maintenance, and emergencies. Integration with telephone systems allows radio-to-telephone communications, while customizable channel access control enhances operational flexibility.
- Leaky Feeder Cable:
The designed leaky feeder cable radiates radio signals and allows reception within 50-200 meters. Line amplifiers, strategically placed every 350m, maintain signal levels over long distances. The system’s power is backed by Intrinsically Safe Uninterrupted Power Supplies (UPS), ensuring functionality even during power outages.
- Line Amplifier:
Amplifiers, powered via coaxial cable, play a crucial role in maintaining communication throughout the mine. These are strategically positioned to cover all working faces and areas, enhancing overall communication reliability.
- Branch Units:
Branch Units cater to coverage in tunnels not on the main travel route, such as cross-cuts or returns. Available in three-way and four-way versions, Branch Units enable leaky feeder installation in all mining areas, ensuring comprehensive radio coverage.
- Growing with the Mine:
The Leaky Feeder System evolves with the mine’s expansion. Additional cables and amplifiers can be seamlessly added to the arterials, with electrical personnel easily extending the system without extensive training.
- Repairs and Extensions:
Quick repairs and connections are vital for minimizing downtime. Becker’s splice units, including line splices for joining cable sections, address these needs. Line terminations are essential for proper system termination.
- Two-Way Radio:
Becker’s compact UHF intrinsically secure (I.S.) portable radios offer versatility and reliability. Designed for use in challenging mine environments, these radios provide efficient communication in a small, rugged package.
Conclusion:
Beckercom’s I.S. Radio System stands as a reliable and adaptable solution, ensuring seamless communication and operational efficiency in mining environments. From initial implementation to growing with the mine’s expansion, the system provides a comprehensive and innovative communication infrastructure.
