Network cable STEINMARK CAT5 UTP 305 m LSZH — 305 m unshielded twisted pair cable

STEINMARK CAT5 UTP network cable on a 305 m reel is an unshielded twisted pair cable with a Low Smoke Zero Halogen (LSZH) outer sheath. It is engineered for Category 5 Ethernet and LAN installations, offering a continuous long length that simplifies structured cabling, horizontal runs and patch-panel connections in indoor environments where reduced smoke and halogen emissions are required.

Advantages

The LSZH sheath reduces hazardous smoke and corrosive gas emission in the event of fire, improving safety in enclosed spaces. Unshielded twisted pair construction provides reliable signal transmission for standard Ethernet applications while remaining flexible and easy to route. The 305 m reel minimizes joins and interruptions during installation, saving time on long cable runs and allowing cleaner cable management in racks and conduits.

Suitable for

• Indoor structured cabling for offices and commercial buildings
• Horizontal cable runs between patch panels and wall outlets
• LAN and Ethernet installations at Category 5 performance
• Environments requiring reduced smoke and halogen emissions (public buildings, data rooms, residential common areas)

Key specifications

• Cable type: Unshielded twisted pair (UTP)
• Category performance: Category 5 (Cat5)
• Length: 305 m continuous reel
• Sheath: Low Smoke Zero Halogen (LSZH)
• Application: Ethernet/LAN structured cabling and patch runs
• Installation: Indoor use, suitable for conduit and cable trays

How to use

Plan the cable route and measure required lengths considering the 305 m continuous reel to minimize splices. Use appropriate cable management tools such as cable ties, trays and conduits. Strip the LSZH sheath carefully with suitable tools to avoid nicking the inner conductors. Terminate with compatible RJ45 connectors or patch panels rated for Category 5 performance, following standard wiring schemes (TIA/EIA or ISO) and maintaining correct pair untwist lengths to preserve signal integrity. Test each run with a network cable tester to verify continuity, pair mapping and performance before finalizing installations.

Usage recommendations

For best results, store the reel flat and avoid tight bends below the manufacturer’s minimum bend radius. Keep the cable away from strong electromagnetic interference sources and high-voltage power lines. When installing in public or safety-sensitive spaces, use LSZH cabling to reduce smoke and toxic gas risks. Verify that Category 5 performance meets bandwidth requirements for your network; consider higher-category cable for future-proofing when higher speeds are needed.
