FIELD: electrical and radio engineering, equipment lying cables and wires.
SUBSTANCE: invention is related to lying of electric cables and wires. Tray to lay cables or wires has case and cover with open butts. Case includes bent upper edge on each sidewall and forms groove outside and convex collar above it. Cross-section of cover follows form of cross-sections of grooves and collars to form lock joint between cover and case. Internal edge of each collar is bent with formation of space locating connecting bar. System to lay-out cable lines has at least two trays made by manner described above as well as at least one linking element attached to open butts of adjacent trays, it can have at least two connecting bars arranged on each side in spaces of adjacent trays. Connecting straps and tray connectors can be employed in the capacity of linking elements.
EFFECT: system can include additional route bypasses and branchings.
