LSHF Alternative to Belden 8761NH Single Pair Screened Data Cable

The conductor material used is tinned copper, 22(7) AWG, offering excellent conductivity and durability. The pair insulation is made of polyethylene (PE), ensuring reliable electrical insulation. The cable consists of 1 core, identified by clear and black colour coding for easy identification. The overall screen consists of aluminium foil, providing 100% coverage to protect the cable from electromagnetic interference (EMI). The drain wire is tinned copper, 22(7) AWG, used for grounding. The sheath material is Low Smoke Halogen Free (LSHF), ensuring safety in case of fire. The sheath is grey in colour, giving the cable a neutral, industrial look.

The nominal conductor resistance at 20°C is < 53 Ω/km, ensuring low power loss and efficient data transmission. The capacitance between core-to-core is 70 pF/m nominal, while the core-to-screen capacitance is 130 pF/m nominal, making this cable suitable for high-speed data transfer. The impedance is 75 Ω ± 15, making the cable ideal for a range of network and video applications. This cable is rated for a voltage of 450/750 V (applies to CE marked FSC branded stock only) and can withstand a test voltage of 2.5 kV for 5 minutes, providing additional safety in high-stress environments.

The overall diameter of the cable is 5.1mm nominal, making it compact yet durable. The minimum bend radius is 10 times the outer diameter (OD), ensuring flexibility without compromising the cable's integrity. The temperature rating of the cable ranges from -30°C to +70°C, making it suitable for use in a wide variety of environments. The cable weighs 25 kg/km, making it easy to handle while still maintaining robustness and strength.

This data cable meets several important industry standards for safety and performance. It is flame retardant to BS EN 60332-1-2, ensuring it will not propagate fire. It also has low smoke generation as per BS EN 61034-2 and meets the halogen gas emission standards BS EN 60754-1&2, making it safe to use in areas where safety is paramount. The cable is RoHS compliant, meaning it is free of harmful substances. It has been weather-tested to ISO 4892-3, ensuring it can withstand harsh outdoor conditions. The cable is CE compliant, meeting the requirements of LVD (2014/35/EU) and CPR (305/2011), and has a CPR classification of B2ca s1a, d1, a1 (EN50575:2014+A1:2016), ensuring its suitability for use in construction and other high-risk environments.
