PROCESS OF CABLE ( WIRE ) LAYING IN CABLE DUCT

摘要

electrical engineering. SUBSTANCE: process specifically refers to methods of laying of various cables and wires in cable ducts and is intended for use in industrial, administrative and residential buildings. Process of cable or wire laying in cable ducts involves application of load and subsequent placement of cable or wire in duct of cable-carrying tube. Novelty of process lies in manufacture of cable-carrying tube in the form of body with holes in surface. After placement of cable or wire in duct it is fixed relative to surface of duct. Fixing is conducted by way of preliminary placement of cable or wire in zone of holes, by squeezing of individual parts of cable or wire in zone of holes beyond bounds of duct and by their later fixing on surface of cable- carrying tube beyond limits of duct. EFFECT: expanded arsenal of technical aids. 2 cl, 2 dwg
