Šviedšķiedras kabelis B2Ca OS2 universālai lietošanai, ugunsizturīgs FireHardy ZW-NOTKtsdD / U-DQ(ZN)BH - SM 24J 9/125 LSOH ALANTEC

Universal-use cable: outdoor-indoor. The optical fibers remain protected from moisture by a swelling water-absorbing layer, and are protected from rodents by fiberglass. The B2ca non-flammable sheath has been tested and complies with CPR 305/2011 regulation, meets the requirements of strict safety standards (hospitals) and is perfect for use in buildings with high safety requirements (commercial buildings and offices). This is confirmed by the relevant quality certificate.PHYSICAL PROPERTIESOuter diameter6.5 mm* (cable outer diameter tolerance +/- 5%)Weight24 fibers: 55 kgMax. tensile force (static)1000 NTensile force (dynamic)2000 NCompression resistance (max.)200 N/cmMin. bending radius during installationR = 50 mmWater resistanceresistant to longitudinal water penetration due to swelling layerRodent protectionYes (aramid fibers form a barrier that is difficult to gnaw through, which significantly reduces the risk of damage caused by these animals)CPR euroclassB2caCONSTRUCTIONStrength elementsfiberglass sheathOuter sheathLSOH – halogen-free, UV-resistant, thickness 1.3 mm, yellow color, white information inscription, length marking every 1 mFiber colors1.
