Tunnels VHF Leaky Feeder Cable PVC Low smoke halogen free jacket

•  Quick Details:
• Oxygen free copper inner conductor (99.99% copper )
• Virgin grade PE insulation
• Flam retardant jacket
• Low smoke halogen free PE jacket is availiable
• MSHA certificate

Description:

MSHA certified leaky feeder cable, Meet IEC1196 and EN50117.

The leaky feeder cable has a radiation pattern of 360 degrees around the cable and can be strapped directly to a centenary cable, water or air pipe. The standard length is 350m or 500m with a yellow outer jacket.

As an option, the cable can be manufactured according to order with a blue color outer jacket and low smoke halogen free jacket is also available.

Applications:

• Mines underground communication system
• metro stations
• tunnels
• ships
• In-building wireless systems.
• perimeter detection
