Self-Supporting Dielectric Optical Cable OKMS for Reliable Communication

Self-supporting dielectric optical cable for suspension on supports of communication lines, contact network and auto-locking of railways, power lines, lighting poles, between buildings and constructions, for laying protective plastic pipes (PPT), including pneumatic laying method, in blocks, cable trays, in tunnels, collectors, on bridges and overpasses, inside buildings and structures and operation at ambient temperature from minus 60 °? to 70 °?. The outer sheath is made of polymer compositions with consideration of application: when suspended on overhead transmission line supports under the influence of electric field potential more than 12 kV - from tracking-resistant polymer; less than 12 kV - from polyethylene; when the cable enters the premises from polymer compositions not spreading combustion; power elements from aramid threads or glass roving, inner sheath from polyethylene (or without it), optical modules twisted around the central power element. Optical characteristics: K...
