LAN Network Cable STEINMARK CAT6 UTP 305m CPR Class Dca s2 d2 a1, LSZH, 4-pair

STEINMARK CAT6 UTP LAN Network Cable is a 4-pair, unshielded twisted pair cable supplied on a 305 m drum, designed for structured cabling and Gigabit Ethernet. The cable features a low-smoke, zero-halogen (LSZH) jacket and meets CPR fire performance Class Dca s2 d2 a1, making it suitable for indoor installations where reduced smoke and corrosive gas emissions are required. This cable supports high-speed data transmission for horizontal and vertical network runs in offices, data centers and similar environments.

Advantages

The STEINMARK CAT6 UTP cable provides consistent performance for Gigabit Ethernet with four twisted pairs engineered to minimise crosstalk and maintain signal integrity. The LSZH outer sheath reduces smoke density and eliminates halogenated compounds in case of fire, while the CPR Class Dca s2 d2 a1 rating informs about its controlled contribution to flame propagation and smoke production. Supplied on a 305 m drum, the cable is convenient for longer runs and reduces the need for multiple joints or reels during installation.

Suitable for

• Office local area network installations and horizontal cabling
• Data centre patching and inter-rack connections
• Vertical riser runs and multi-storey building cabling
• Structured cabling projects requiring LSZH sheath and CPR Class Dca

When it may not be suitable

This CAT6 UTP cable is intended for indoor use and environments where LSZH and CPR Class Dca characteristics are required. It is not intended for outdoor direct burial, prolonged UV exposure, or installations where mechanical protection against crushing or rodent damage is needed without additional conduits or protective tubing. For shielded cabling requirements (e.g., environments with high electromagnetic interference), a shielded FTP/STP cable would be more appropriate.

Key specifications

• Cable category: Category 6 (CAT6)
• Cable type: Unshielded twisted pair (UTP), 4 pairs
• Length: 305 metres on a drum
• Jacket material: Low Smoke Zero Halogen (LSZH)
• Fire performance: CPR Class Dca s2 d2 a1
• Application: Gigabit Ethernet and structured cabling

How to use

Unwrap the required length from the 305 m drum and cut using appropriate cable cutters. Strip the LSZH jacket and prepare individual pairs following standard T568A or T568B termination schemes, depending on your network design. Use quality RJ45 connectors or patch panels rated for CAT6 to preserve performance. Route the cable through cable trays, conduits or risers keeping bend radius recommendations and avoid tight bends or kinks. Test terminations and channel performance with a certified cable tester after installation.

What to consider before purchase

• Confirm required cable category (CAT6) and whether UTP is suitable for your environment regarding electromagnetic interference.
• Verify indoor use suitability and whether LSZH and CPR Class Dca s2 d2 a1 meet building and fire-code requirements.
• Plan cable length and routing to ensure 305 m drum size fits your installation strategy and reduces waste.

Usage recommendations

For reliable Gigabit performance, maintain separation from power cables, secure cables with appropriate clips or trays, and perform post-installation certification testing. When installing in multi-floor buildings, verify local regulations for CPR and LSZH requirements and protect cable runs where mechanical damage risk exists.
