LAN network cable CAT6 UTP STEINMARK 305m CPR Class Cca LSZH for indoor installation

STEINMARK LAN network cable CAT6 UTP on a 305 m drum is designed for indoor structured cabling where Gigabit Ethernet and reliable data transmission are required. The cable uses four twisted-pair conductors in an unshielded configuration and is covered with an LSZH (low smoke zero halogen) jacket. It is manufactured to meet CPR Class Cca fire performance, reducing smoke and toxic emissions in confined spaces and making it suitable for offices, server rooms and residential installations that require enhanced fire safety.

Advantages

This CAT6 UTP cable supports Gigabit Ethernet and typical data network speeds for modern local area networks while maintaining consistent signal quality over horizontal runs. The LSZH outer sheath limits smoke production and halogen release in case of fire, improving occupant safety and reducing corrosive residues on equipment. Supplied on a 305 m drum, the cable is convenient for longer runs and reduces the need for joins, enabling neater installations and fewer connection points.

Suitable for

• Horizontal and riser runs in office and commercial buildings
• Wiring in server rooms, telecom closets and data cabinets
• Residential structured cabling where low-smoke materials are preferred
• Gigabit Ethernet networks and PoE applications within standard power limits

When it may not be suitable

This unshielded CAT6 cable is not designed for environments with high electromagnetic interference where shielded cable variants would be preferable. It is intended for indoor fixed installations and is not rated for direct burial, outdoor exposure, or use in conduits subject to continuous moisture without additional protection.

Key specifications

• Cable category: CAT6 (unshielded twisted pair)
• Length on drum: 305 metres
• Conductor arrangement: 4 twisted pairs
• Sheath type: LSZH (low smoke zero halogen)
• Fire performance: CPR Class Cca
• Intended environment: Indoor installations
• Typical applications: Gigabit Ethernet, data networking, PoE within standard limits

How to use

Plan the cable route and measure required lengths before cutting from the drum to avoid waste. Terminate the cable with compatible CAT6 RJ45 connectors or keystone jacks following standard T568A or T568B wiring schemes, ensuring pair integrity and correct pair untwist limits near terminations. Use proper cable support, avoid sharp bends and do not exceed the recommended pulling tension. When installing in risers or plenum-type spaces, verify local regulations to confirm suitability of CPR Class Cca and LSZH materials.

What to consider before purchase

• Verify that an unshielded cable meets electromagnetic interference conditions of the installation site
• Confirm length requirements and whether 305 m drum size fits planned runs without excess waste
• Ensure required fire performance class and LSZH jacket meet local building codes
• Check connector and termination method compatibility (RJ45, keystone jacks, patch panels)

Usage recommendations

For optimal performance, use this CAT6 UTP cable for horizontal runs up to the standard channel length, maintain proper bend radius, keep separation from power cables where possible, and test completed links with an appropriate network cable tester to confirm wiring correctness and performance before putting the network into service.
